The invention discloses a control method for charging a storage battery of an electric vehicle, which is characterized in that a storage battery under-voltage wake-up circuit is additionally arranged in a DCDC device connected with the storage battery in parallel, and when the voltage of the storage battery is too low, the storage battery under-voltage wake-up circuit generates a wake-up signal to wake up a VCU, a BMS, the DCDC and a T-BOX, so that the charging of the storage battery is realized. By means of the mode, electricity can be effectively supplemented to the storage battery of the electric vehicle in time, cost is low, power consumption is low, and controllability is good.
本发明公开了一种为电动汽车蓄电池补电的控制方法,通过在与蓄电池并联的DCDC装置中增加蓄电池欠压唤醒电路,当蓄电池电压过低时,蓄电池欠压唤醒电路产生唤醒信号来唤醒VCU、BMS、DCDC、T-BOX,实现对蓄电池的补电。通过上述方式,本发明能够及时有效地为电动汽车蓄电池补电,成本低,功耗低,控制性好。
