Vehicle electrical power management system based on an adaptive dual-path controller power supply

A vehicle electrical power management system (VEPMS) is proposed, based on a new vehicle electrical power supply mechanism. As a classified power supply mechanism, it supplies power for electronic control units and traditional electrical devices separately, resulting in clean, pollution-free control signals, with no electromagnetic interference. According to the requirement of electronic control units and communication, an adaptive dual-path controller power supply is designed, to manage the electrical power supply and realize over current protection. Prototype is developed and tested, which confirms that it can achieve stable management and ensure electrical power supply safety.
