The invention provides an electric vehicle energy management method, an energy storage management controller and an energy management unit. The energy storage management controller firstly controls abattery to carry out the high-voltage power distribution on a high-voltage device, provides high-voltage power for a battery thermal management system, supplies power to a low-voltage power supply ofa whole vehicle through a DCDC power supply, then detects the working states of the battery, the high-voltage device and the battery thermal management system, and sends a control instruction according to the working states so as to carry out power-on and power-off control on the high-voltage device and carry out charging and discharging management on the battery. Therefore, the energy storage management controller can independently realize high-voltage management of the electric vehicle, and does not need a VCU and a BMS to realize decentralized management of high-voltage devices in the priorart, so that the problems of high complexity and high difficulty of high-voltage management caused by decentralized management in the prior art are avoided.
本发明提出一种电动汽车能源管理方法、储能管理控制器和能源管理单元,其储能管理控制器,首先控制电池为高压器件进行高压配电,且为电池热管理系统提供高压电,并通过DCDC电源为整车低压电源供电;然后,再检测电池、高压器件和电池热管理系统的工作状态,依据工作状态发送控制指令,以对高压器件进行上下电控制,以及,对电池进行充放电管理。因此,本储能管理控制器可单独实现对于电动汽车的高压管理,而无需现有技术中VCU来与BMS共同实现对于高压器件的分散管理,进而避免了现有技术中由于分散管理带来的高压管理复杂度高和难度大的问题。
