Although battery-management systems (BMS) don't get much attention, modern electric vehicles (EVs) would not be possible without them. Tucked away inside every EV's battery pack there’s a BMS that’s responsible for insuring the safety and longevity of their powerful, but temperamental, cells.
Now, as EVs enter the mainstream market, both their batteries and the BMS technologies they rely on must evolve to meet the market's growing expectations for improved price, performance, and reliability. In this article, we'll discuss a few of the most significant issues driving the evolution of EV batteries, and how tomorrow’s BMS will help address them.
