Customer ServiceDesigning an efficient auxiliary battery system presents unique challenges, particularly as EV technology continues to advance. These challenges include balancing power demands, ensuring safety, managing battery life, and maintaining system efficiency.
Customer ServiceEnsuring 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.
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.
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.
The auxiliary battery acts as the backbone of the system to support the proper operation of the vehicle. It is important to ensure the auxiliary battery has enough energy to meet the basic loads regardless the vehicle is in park or running.
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.
As a result, the energy consumption remains low while the SoC of the auxiliary battery is sustained. Since the auxiliary load represents an important part of energy consumption in the vehicle, an optimal energy management strategy for the Auxiliary Power Unit (APU) is necessary.
