In EVs, while there is no traditional engine to start, the vehicle's low-voltage systems need to be activated before the high-voltage propulsion battery can power up the motors. The auxiliary battery is responsible for powering the systems that manage the activation of the high-voltage system.
Electric vehicles still consume power when idle. Climate control, keyless entry systems, alarm systems, and internet connectivity all draw small amounts of power when the vehicle is not in motion. The auxiliary battery handles these power draws, ensuring that the primary propulsion battery retains its charge for driving.
While the primary focus of EV development often revolves around the propulsion battery, auxiliary batteries play an indispensable role in powering non-propulsion systems. From supporting safety features and infotainment systems to ensuring vehicle operation and redundancy, the auxiliary battery is an unsung hero in electric vehicle design.
Ensuring Safety and Redundancy: The auxiliary battery in an EV acts as a redundancy mechanism. In case the main propulsion battery fails or depletes, the auxiliary battery ensures that essential systems like hazard lights, power locks, and emergency communication systems remain operational.
Battery Management Complexity: Integrating an auxiliary battery system with the high-voltage propulsion battery requires sophisticated battery management systems (BMS) to ensure seamless operation. Balancing the charge and discharge cycles of both battery systems adds to the complexity of the overall vehicle design. 2.
It is important to ensure the auxiliary battery has enough energy to meet the basic loads regardless the vehicle is in park or running. However, the existing methods only focus on auxiliary energy management when the vehicle is in a dynamic event.
