![]() ![]() The 12-volt battery ensures that autonomous systems are fail-safe, operating even if a car’s primary power source stops functioning. The automotive industry is moving beyond simple safety and convenience features to advanced driver assistance systems and, ultimately, to fully autonomous vehicles – both internal combustion and all-electric. In turn, the high-voltage battery recharges the 12-volt battery and supports loads during the drive cycle. Drivers rely on the 12-volt battery to safely initialize the high-voltage battery, and to power vehicle applications when the high-voltage system is disengaged. The 12-volt battery plays a critical role in supporting the car’s electrical network throughout the drive, powering everything from heated seats and infotainment systems to cutting-edge safety features like pedestrian detection systems.Įlectric vehicles require two interdependent batteries: a high-voltage battery that powers the drivetrain, and an advanced 12-volt battery that handles key offloads. The amount of power consumed by vehicle features and electronic devices has doubled in the past 10 years and is projected to double again in the next five. Today’s automotive battery must do much more than start the car or keep the radio playing at the end of the drive. Providing more power throughout the drive ![]() Here’s how it remains a critical source of power across the evolving range of vehicles.ġ. As vehicles become more electrified and more autonomous, the 12-volt advanced lead-acid battery is taking on new and challenging responsibilities. ![]()
