The invention discloses a new energy vehicle type storage battery charging control method, and belongs to the technical field of electric vehicle storage batteries, and the method specifically comprises the following steps: detecting the SOC value of a storage battery EBS; when the gateway control unit detects that the SOC value is in a power shortage state, a CAN network is awakened, and a power supplementing request is sent to the whole vehicle control unit; after receiving the power supply request, the vehicle control unit judges whether a power supply condition is met or not, if yes, a storage battery is supplied with power through high-voltage power on, and a power supply signal is fed back to the gateway control unit; after the gateway control unit receives the electricity supplementing signal, the SOC value of the storage battery is detected, and electricity supplementing timing is started; and in the electricity supplementing process, electricity supplementing termination conditions are judged in real time, and when the electricity supplementing termination conditions are met, electricity supplementing is stopped. According to the charging method, when the electric quantity of the storage battery is low, the storage battery is charged in an automatic high-voltage power-on mode, the storage battery is not charged in a low-voltage mode, and the situation that the storage battery is insufficient in power due to the whole vehicle cost limiting factor or the controller software and hardware limiting factor can be avoided.

    本发明公开了一种新能源车型蓄电池补电控制方法,属于电动汽车蓄电池技术领域,具体包括如下步骤:检测蓄电池EBS的SOC值;当网关控制单元检测到SOC值处于亏电状态,则唤醒CAN网络,向整车控制单元发送补电请求;整车控制单元收到补电请求后,判断是否满足补电条件,如满足,高压上电给蓄电池补电,并向网关控制单元反馈补电信号;网关控制单元收到补电信号后,开始检测蓄电池SOC值,并开启补电计时;补电过程中实时判断补电终止条件,当满足补电终止条件时,停止补电。该补电方法在蓄电池电量偏低时,通过自动高压上电的方式给蓄电池补电,且低压并不上电,可避免因整车成本限制因素或控制器软硬件限制因素导致的蓄电池亏电。
