Battery Technology

Batteries have come a long way. There are still a lot of things we can do with existing technologies and this was covered in Making Batteries Better.

Lithium Ion Battery

The leading Rechargeable Battery Technology at present is the Lithium Ion Battery because of the high energy density and reduced weight compared to Lead Acid Battery technology. But there is a problem with them wanting to explode so a lot of care is required in both making and using the Lithium Ion Batteries. And there are different types suited to different applications including non-rechargeable Primary Cell application.

Sodium Ion Battery

An emerging Battery Technology is the Sodium Ion battery. And it has a number of advantages.

The advantages it brings to the table are:

  • not a rare material like Lithium
  • much more stable
  • can be charged faster
  • can deliver higher discharge currents
  • are able to supply the same voltage range (around 3.6V)
  • will be cheaper to make, and use, and recycle

The idea has been around since the 1970s but took a back seat to Lithium Ion Battery technology. Now Sodium Ion Battery technology it is coming to the fore and key researchers in Australia are helping to make that happen. The diagram below shows how it works. Click on the diagram for a full sized view.

The high cost and scarcity of lithium are driving research to develop alternatives to lithium-ion batteries, especially to meet future needs in energy storage. One potential alternative is sodium-ion batteries. (Purdue University image/Vilas Pol)

Some further reading for those interested:

Better and more affordable batteries will be one aspect of adding storage to the Electrical Grid and make renewables more viable for base load demand satisfaction.

Electrical Power Distribution

Electricity is essential to the modern world. It is the power source behind the vast majority of modern appliances. And for large quantities of it, we are currently mostly burning things to produce heat to run generators to create AC power to transformers to high voltage power lines to more transformers, low voltage power lines and eventually, homes, businesses and facilities.

AC power distribution has become the dominant way power is distributed because it was easier and more reliable to make big transformers than do DC/DC power conversion. And to reduce heat losses in wires higher voltages at lower currents is a good strategy. This is Electrical Engineering 101 material.

Today however, this has changed. DC/DC power conversion is now routinely used at high voltages and is more efficient than a transformer. So that saves some of the burning which helps reduce carbon emissions and can help with a range of concerns from climate change to pollution.

A good example of this is Basslink which passes power from Tasmania to Victoria at 400kVDC. While there is some criticism that it doesn’t deliver the originally planned 630MW (only goes to 500MW) it is still a good example of this type of technology.

Reducing Losses

There are other options for reducing losses and Power Factor Correction is one of the primary ones. This process add leading power factor capacitive reactance to the distribution grid by putting capacitors in to correct for lagging current due to lagging power factor inductive reactance from the dominant loads in the system such as motors etc. A good example of products that manage this are the ABB CQ900 and CQ930 smart power controllers. Both Australian design and made products. These are networked and Smart Grid enabled.

The other strategy is reduces losses at the loads. So LED lighting, building management systems, better insulation and better business models that make it worth the while of the asset developers to consider the long term energy footprint of running the asset. This is covered very will in Natural Capitalism.

Improving Distribution

In Electricity Grid 2.0 and Global Power Grid we explored what a world electricity grid could look like if we started again now. And High Voltage Direct Current plays a key role as do renewables and storage. However, if it really is a world grid then the sun will always be shining somewhere and when it is winter here is is summer elsewhere so a lot of the issues with variability can be averaged out.

 

Improving Load Management

Companies like Rectifier Technologies Pacific design and make higher efficiency power supplies for backup power, uninterruptible power supplies and data centers. This is an important way to reduce power losses. It also won them some iAwards.

Another approach is to micromanage the AC power itself and this is being done by companies like 3DFS that are putting microsecond level load demand management into data centers. They call is Software Defined Electricity. and it works by cleaning up the fluctuating demand distortion of the AC sine wave our Power Distribution Network is meant to be delivering.

3DFS Cleaning Up AC Power

They have some very advanced ideas on how to go about this and already have products in the market. You can get a good understanding of their overall strategy from the video below.

An even more interesting idea is that of making devices smarter so they work with the grid to manage their own demand so the total process is more efficient overall.

And finally, Low Power Electronics devices can reduce the amount of power needed to achieve a function. Some of the technologies we are working with now allow up to reduce power consumption by 3 orders of magnitude.

So there are lots of ways we can do it better and if we work together and use all the tools available to us then it is likely we will succeed at achieving that. The place to start is knowing it is possible.

Electric Vehicles

This is a post I started 6 years ago and decided not to publish. Since then things have changed a lot so here goes.

The History of Electric Vehicles

The Electric Vehicle has been around for a long time. The new push to Electric Vehicles is mostly being pushed by the belief that they will reduce carbon emissions. This really depends on where the power comes from, how efficient the motors are and how well the batteries work. Most studies prior to 2011 have shown that unless a substantial amount of the power comes from renewable energy then it is likely the Electric Vehicle will generate more pollution than a petrol vehicle.

Electric Vehicles began a long time before the petrol vehicle was the norm and even way before Vanguard made the first mass produced Electric Vehicle in the 1970s.

Vanguard-Sebring Electric Vehicle

Vanguard-Sebring Electric Vehicle

 

Although details vary, 1828 is generally regarded as the date of the First Electric Vehicle and Anyos Jedlik put together a small scale model decades before the modern combusion engine cycle was invented. And the challenge was the same then as it is now, the battery. The History of Electric Vehicles is also the History of the Battery.

Jedlik Electric Car

Jedlik Electric Car

So what happened to the Electric Vehicle?  The challenge today is still the same, the Battery. We really need a better solution. Which is where my original post stopped.

Guess what? It seems to have happened.

Tesla et al

So enter Elon Musk and Tesla Motors. His purpose is to take petrol off the road so they have done some pretty innovative things including opening up their patent database so anyone can use their technology with their permission.

Tesla

Tesla

And of course Nissan, Toyota, Honda and many others are putting Electric Vehicles front a center in their product lines now.

With improvements in energy density storage and reducing costs for high capacity batteries we are approaching a time when Battery Electric Vehicles are the better choice for the environment, even when charged with electricity derived from fossil fuels. Studies show that there are more Emissions from the manufacture of a Electric Vehicle, but this is made up for in 1 year of operating emissions improvements and over the course of the Electric Vehicle’s life, Global Warming Emissions are halved. This assumes a 50mpg (US based study) petrol vehicle is used for the comparison. This equates to 21.3Kpl or 4.7L/100Km so this is as realistic comparison with a high efficiency petrol or diesel vehicle.

What a big different 6 years makes.

Hydrogen Fuel Cell Cars

So how are Hydrogen Fuel Cell based cars progressing? Calculations are that it will be roughly 3 times less efficient that a Battery Electric Vehicle. And extracting the H2 also requires energy. So H2 is an energy storage source. It is hard to store and manage and so the infrastructure costs are also high. So it is hard to do. The plus is that you don’t consume any fossil fuels in the process if you use some of the new solar based extraction mechanisms so although there are big drawbacks, there are also big benefits. The following video covers the territory well including some commentary from Elon Musk toward the end.

Let’s look at another perspective which is more optimistic.

So the infrastructure just isn’t there. So it looks like Battery Electric Vehicles are still the way to go. But the advantages are big enough that the debate will continue. And it is interesting that we have multiple fuel types in use simultaneously including Petrol (gasoline), Diesel, LPG, Alcohol, Battery Electric, Hydrogen, Biodiesel, compressed air, coal, wood and others.

The big advantages for Hydrogen are:

  • longer operating range than battery alone but not as much as petrol/diesel/LPG
  • no harmful emissions when running, the same as Battery Electric Vehicles and a big improvement over petrol/diesel/LPG

Time will tell. I should put a diary entry into my calendar for 6 years time and do another comparison.

Powering Telemetry

A big issue in the world of the Internet of Things, or IoT as it is abbreviated, is how to get power to remote devices. And this splits up into 2 separate but definitely related problems:

  • the power source
  • the power consumption

Obviously, if the power consumption is high, the power source has to be capable of providing a lot more power. We looked at this in our IoT – Remote Telemetry Case Study. So let’s tackle that one first.

And the focus for this article is remote devices using Solar Charging. Before we look at that specifically, let’s understand the problem.

Power Consumption

There are multiple ways to reduce power consumption. These were covered already in Reducing Power Consumption and Reduce Power While Awake with examples given in Sleep Saves Energy.

Low Power Sleep Mode

Low Power Sleep Mode

The short version of this is that you have to do 2 things at the same time:

  • reduce the average power that is consumed all the time
  • reduce the energy required to process an event

The first of these is also known as Quiescent Power Consumption. This is the power consumed just running the system when it is doing nothing, or close to it. At a minimum, the Power Supply has to deliver this amount of power just to make sure that we could react to an event, should it occur. And I can hear you thinking that it is hard to get this low enough and still have a responsive system.

Correct! But you have to have at least this amount of power or Game Over!

Which is where the second part comes in. You also need some power to respond to events. These can be something you need to log, or reports you need to post. If you are uploading to a web service using cellular communications, the peak power consumption can be very high. So you have to minimise this time.

We would normally model both of these and work out a power budget based on the worst case scenario model. Excel is a suitable tool for doing simple modelling of this as well as scenario modelling.

But I can hear you thinking “why worst case“? Answer: “Because you want it to always work, not just work on average“!

Telemetry

Telemetry means measurement at a distance or remote measurement. So you are measuring something at location A, and want to know the value of the measurement at location B. This implies the 2 locations are not close enough together that this is a trivial problem to solve.

In our world, Telemetry can mean anywhere on earth, though our customers are usually in Australia. In NASA’s world, (maybe world is the wrong term for them) it can be anywhere in the solar system. Voyager 1 is currently more than 18 billion Kilometres away and has been active for 40 years.

Artist's concept of Voyager in flight

Artist’s concept of Voyager in flight

The challenge for low power consumption, is how to get the measurement from location A back to location B?

Solar Charging

The NASA solution is simple. Near sun facilities are Solar Powered, and the rest use some form of nuclear power. Since no-one will ever let us nuclear power any Telemetry device, and I’m Okay with that, and we are near enough to see some sun, we will follow that option instead. And besides which, we can do it in our office and not a heavily shielded facility.

So lets recap on what we know about solar charging:

  • ignoring the energy cost of making a solar panel, the energy cost is free after that
  • there is a maintenance cost which includes cleaning panels
  • provided the construction is robust, they are a long life product
  • you have to do Maximum Power Point Tracking (MPPT) to harvest the most energy or minimise the panel size

And to get more power from a solar panel, you have to:

  • have more sun
  • have a better angle to the sun (cosine reduction)
  • have a better MPPT
  • handle lower voltages
  • use the right silicon

Not all Solar Panels are equal. If you want you panel to work in a mostly shady place then you might also want to use mono-crystalline Silicon solar cells because they are efficient and can continue to convert even low levels of light. In recent developments the efficiency of conversion had passed 25% as reported in Efficiency of Silicon Solar Cells Climbs and some of the stacked cell technologies are past 40% efficiency.

And then you have to harvest that energy. Which is where new devices like the SPV1050 come in. Experiments in our office showed that we can charge a Lithium Polymer battery from the internal lighting. And it is a buck boost converter meaning that it can charge the battery in full sunlight (reducing voltage) and also moonlight (increasing voltage) and the device costs less that $2 in 1K pieces.

I only have on criticism. The super low quiescent current LDOs would have been more useful if they were fully independent because this would have taken another item off the Bill of Materials.

Primary Cells

The other option for Telemetry is using Primary Cells. These are not rechargeable and so must last the life of the product. We currently deploy Cellular based Telemetry modules that can run for up to 10 years from a Lithium Primary Cell or 5 years from Alkaline Primary Cells. This is ideal for Smart City style projects where the devices might be moved as they fulfil their current purpose. A good example of this is people metering or pedestrian counting where a council may want to know how much use an area is getting. Once that is understood, the Telemetry module can be redeployed and since it isn’t connected to mains power you don’t need an electrician to do that. Or they could be used to understand the level of demand of public transport services in real time so you can adjust capacity on the fly.

So there are options and as technologies like NB-IoT and CAT-M1 come online the power budget for cellular communications continues to fall. We covered this in Cellular IoT Communications. And as of last month, Telstra turned on CAT-M1 across the 4GX network.

Putting Light to Work

Light is a really interesting thing. It has so many different aspects. And it took us a long time to work out exactly how it functioned. And in many ways that is still an ongoing process. So this post is a brief survey of some recent advances in our understanding of light, how to use it, and how to generate it.

Extracting Energy from Light

Recent advances in Quantum Dots have taken us one step closer to improving our extracting of energy from light and Solar Cells continue to improve.

So apart from turning the light in electricity, what else can we do with light?

Light for Communication

Light is also useful as a communications tool. And recent advances in Quatum Dot management of light means it could hold the key to higher levels of computing power in the future, as well as more secure communications.

But is there more?

Other uses of light

As it happens, yes there is.

Nanoscale structure purifies water using light

Artificial Photosynthesis extracts CO2

So this remains a very busy space.

LED Street Lighting

With concern for rising global emissions and the majority of the worlds power still generated by burning fuels of one kind of another, the replacement of older street lighting technologies with higher efficiency and longer life LED Street Lighting would appear to make sense. And on the up side, everyone agrees that the longer life of the LEDs compared to other lighting technologies is a huge plus.

However, it turns out to be not as simple as that. In LED Streetlights Are Giving Neighbourhoods the Blues the author, Jeff Hecht, points out a few other issues to consider. The picture below graphically demonstrates one of them.

Modern Street Lighting - Aerial View

Modern Street Lighting – Aerial View

Colour Temperature, or how warm or cold a light appears to our eyes, has a significant impact on how we perceive the lights. Above we see very white looking LED lighting alongside more traditional High Pressure Sodium lamps. The much bluer LED Street Lights cause several serious issues including:

  • actually reducing our ability to see clearly at night
  • disturbing noctural creatures more (eg. hatching turtles)
  • affecting sleep patterns
  • affecting biorythms
  • decreasing our ability to see stars at night

So the energy savings are real, but the environmental side affects are too.

Managing Colour Temperature

Unfortunately LEDs are not as easy to control for Colour Temperature. Unlike an incandescent light, they emit a very narrow band of wavelengths of light. And most White LEDs emit blue and use a phosphor to down convert some of the Blue to Yellow so they look whiter rather than Bluer. The earliest White LEDs were very blue and so early adopters of LED Street Lighting have ended up with the worst outcome. And the more we warm up the colour the lower the efficiency because we lose some energy in the down conversion.

The are some breakthrough underway and Cree have recently discovered that it is more efficient to add some red LEDs to the mix to drop the perceived colour temperature. And this is helping. But even the newest devices are at a colour temperature of 3000K and the High Pressure Sodium Lamps are at around 2100K. So still quite a bit different.

The only solution for the millions of already installed LED Street Lighting is unfortunately to swap them out for more recent LED arrays that are at a better colour temperature.

Batteries Today

There are 4 separate drivers for current battery technology:

  • Cost
  • Size and Weight
  • Capacity
  • Recharge rates and cycles

An example of an emerging industry for batteries is electric vehicles. These require high recharge rates, high capacity, high recharge cycles and acceptable weight, size and cost. So the current front runner in commercial batteries, the Lithium Ion battery, has some challenges meeting these requirements. But it is also the best we have right now.

Adding Super Capacitors

One approach to improving battery performance in peak demand situations is to add a Super Capacitor in parallel with a conventional lead acid battery. The Super Capacitor smooths the energy demand by delivering the high current needed for peak demand and the lead acid battery provides the bulk energy storage.

CSIRO UltraBattery Inventor - Dr Lan Lam

CSIRO UltraBattery Inventor – Dr Lan Lam

The CSIRO developed UltraBattery is a good example of Australian Technology Innovation in next generation batteries. It is one example of their work in Energy Storage. And also good example of their partnerships with industry to bring next generation technologies to commercial reality.

New Battery Technologies

The front runner for the next generation of battery technologies is the Lithium Air Battery. This promises double the energy density per unit volume of Lithium Ion Batteries but at 20% of the weight. So ideal for Electric Vehicles where weight is one of the critical elements.

Lithium Air Battery Chemistry

Lithium Air Battery Chemistry

The reason this is such a promising technology is because it has:

  • high recharge efficiency (90%+)
  • high recharge cycles (>2000 versus 300 for some Lithium Ion batteries)
  • high energy density
  • low weight

So what is the catch?

Researchers believe commercial versions of this battery technology are only 10 years away. That isn’t that long for a new battery technology. The hurdles they still need to face are primarily in protecting the pollution from corroding the metal electrode and preventing dendrite growth which is an existing problem with Lithium Ion Batteries. The electrode wants pure oxygen and is corroded by moisture, carbon dioxide and nitrogen. So some challenges remain.

Using Existing Batteries Better

The other approach is the one we usually take. Use Existing Batteries Better.  This involves better power management, better battery management and rethinking the whole solution to a problem. We showed an example in a recent Remote Telemetry Case Study we did in the Internet of Things space where we took an installation that would have required a 200W solar panel and instead deployed a system that runs from 4xAA batteries for 2 years. The next step is to add an energy harvesting component with a suitable rechargeable technology to take the battery maintenance interval from 2 years to 5 years. Even with the best and most durable rechargeable battery technology around today for regular commercial applications, a 5 year maintenance interval is still needed.

So multiple approaches. I’m looking forward to the next set of breakthroughs in this area. Including marrying the CSIRO Super Capacitors with a Lithium Air Battery.

Local versus global electrical power

Up until recently, AC Power Distribution was the most efficient way to move electrical energy about. But right back at the beginning of electricity, it wasn’t obviously the case. Thomas Edison had favoured DC voltage and current distribution but was defeated commercially by almost all other comers because the technology to do AC Voltage Transformation, the transformer, was just easier top make than a DC version based on the technology of the day.

Thomas Edison

Thomas Edison

You can read more about this era in the War of Currents. This was the 1880’s of course. Probably the highest fundamental invention decade so far. But that is for another post.

Modern DC Power Distribution

Wind forward more than 100 years and the technology to transform DC voltage and current, at high efficiency, is mainstream. Of course the incumbent AC infrastructure is wide spread and not easily displaced. But DC is winning ground in new installations.

In Australia, Basslink is connecting Tasmanian power generators to the Victorian electricity grid using HV/DC or High Voltage DC Technology. It is now the technically superior offering.

World Power Grid

And so the new opportunities open up for sharing power across the globe. The current plans are just for grid connect. But if you consider renewable energy as a major contributor, if we have a globally connected grid then the solar power generators sun side can be supplying the night side communities and 12 hours later the other way around. If solar goes global and the grid goes global, then the fluctuating and time of day dependent power generation can be balanced out globally. What we can’t make economic in a single region, can suddenly become overwhelmingly compelling across the globe.

That will require quite a lot of collaboration and market trading beyond what has traditionally been possible, but the pay off would prove worth it. I am going ahead of what we can currently do, but I also believe this is where we have to get to.

Global Power Grid

Global Power Grid

For more information on the current state of play, check out the IEEE article on Let’s Build a Global Power Grid.

And you can be sure we will be doing all we can to support the push.

Internet of Things

The Internet of Things, or IoT as it is abbreviated to, is still an emerging trend. But it is driving some substantial changes in some industry areas. This includes the 4th Industrial Revolution, also known as Industry 4.0.

If you are deploying to a factory or industrial complex, then generally the networking and power is already dealt with and you can piggy back off the existing infrastructure. But what about deploying Remote Telemetry? If you wanted to measure water tank levels or water usage in a rural location you might have to use a solar powered or primary battery powered system and 3G or 4G communications to get the data back to a website or server. That can have its own challenges. The typical industrial computer used for these monitoring tasks and posting reports or transactions requires a lot of power to run and is expensive. So can you do it if the budget for the hardware is $600, you don’t want to use solar cells and also don’t want to change the batteries every month?

The answer is YES. Check out this short video to find out how.
