Research on Low Power Consumption of Battery Management System for Hybrid Electric Vehicle 2008-01-1571
Based on self-designed battery management system, the hardware construction and software strategy is researched for decreasing system's power consumption. Moreover, four different working modes are set to control the system. They are normal mode, idle mode, standby mode and sleep mode, among which the system can switch according to definite internal or external conditions so as to realize as low power consumption as possible. Especially, when vehicle stops for a long time, the system enters the sleep mode through controlling hardware and software, where extremely low power consumption is achieved. The strategy of low power consumption also has its general value for other vehicle embedded systems.
