 Our research is cutting edge because we're working on new methodologies to diagnose and prognose batteries. And we want to do it using only the sensors that are available in the field. We're working here mostly on single cells, that means one single battery. If you look at a car or a storage system, you have thousands of batteries plugged together. But we test the exact same single cell. We have around 100 channels for testing batteries at the same time. So any size from a few amp-power to 100 amp-power is not a problem. For each channel, we can have a battery do whatever we want. We can simulate driving a vehicle. We can simulate the input of a solar panel. We can simulate the usage of a home. We can simulate a cell phone usage. And so we can test the battery over and over 24-7, so that we know after 100,000 to 200,000 cycles what the battery would be under those particular conditions. We are working mostly on lithium-ion batteries. Lithium-ion batteries are powerful, they're reliable, they last quite a long time, so they're a really good candidate for battery storage. Batteries are deployed to the grid. Since electricity is produced and used at the same time, we need to be able to store energy. So if there's a cloud, it's coming, or the wind dies, we still have power. Batteries are great because they are really efficient. What we put in, we get a vast majority out. When we have a commercial cell, what we do is we open it in a glove box so it's safe. And we harvest each electrode that we can test individually with metallic lithium. Then we can take that information and build a virtual cell in a way on the computer. And from that virtual cell, we can simulate any possible degradation and know how the voltage would change. And then we just have to compare that to what we observe on our testing and we know how the cell degraded. We can help customers really understand their battery, and make sure they use them to their fullest so they can extend the life to the maximum. And also, which is really important, is to operate them safely.
