When you think of safety in an electric vehicle (EV), airbags, stability control, and driver assistance features might come to mind. But behind the scenes, one small component makes all of these systems possible: the 12V battery.

Every electric vehicle (EV) runs on not just one battery, but two. While the high-voltage battery pack gets most of the attention for powering the car, the smaller 12V battery is equally important for safety and everyday functions.

Every electric vehicle (EV) has two batteries: the big high-voltage pack that drives the car and the smaller 12V battery that powers electronics and safety systems. While the high-voltage pack gets most of the attention, the 12V battery is just as critical, and it wears out much faster.

When most people think about an electric vehicle battery, they picture the big high-voltage pack that drives the car. But every EV also has a 12V battery, and just like in petrol or diesel cars, it doesn’t last forever.
