The news is filled with stories about automakers going all-in on electric vehicles. Thirty-three electric models were released last year, and automakers such as General Motors have plans for all-electric vehicle lines by the start of the next decade. The first step in servicing them is to get familiar with a few concepts. Since the introduction of smart charging systems in the '90s, battery management systems (BMS) have existed in some form. Electric vehicles (EVs) have a more sophisticated , BMS to help protect the high-voltage (HV) battery and extend its life. BATTERY PROTECTION: A BMS is designed to keep a battery safe (during its normal use) to operate the electric vehicle and while charging the HV battery. It does this by closely monitoring the pack's temperature at various locations, controlling the battery's voltage and amperage while driving and charging, and keeping the battery balanced amongst its cells. These are just a few of the BMS' primary functions in keeping the battery safe. |
