Since I began in October 2011, I’ve written a couple of these every day, and I’ve covered a huge variety of topics, including:… Read more »

The challenges of battery state of charge measurements

Your BMS’s fuel gauge is lying to you. Here’s why that’s not a big deal. Battery management systems (BMSs), and the fuel gauges in them, are a part of daily life for almost everyone. You’ll find them in vehicles, laptops, cell phones, grid-attached energy storage – basically, anything that does work and needs to be plugged in,… Read more »
