The invention discloses an intelligent charging and discharging method. The method comprises the following steps that 1, a mobile phone APP displays vehicle information; 2, a vehicle owner sees the information state of the whole vehicle through the APP and then sends an instruction to the whole vehicle through a 4G signal of the APP; 3, a whole vehicle receiving terminal sends the instruction to a vehicle-mounted charger and a storage battery system through a CAN network; and 4, the vehicle-mounted charger and the storage battery system carry out intelligent charging on the storage battery according to needs, and carry out intelligent charging on the power battery. According to the intelligent charging and discharging method, OBC and DCDC can be deeply integrated, and automatic power distribution can be achieved; charging and discharging are carried out according to the power grid power utilization state, the power utilization peak is avoided, and the client use cost is reduced. And the DCDC is automatically started according to the state of the storage battery and is closed regularly, so that the risk that the vehicle cannot be started through storage battery feeding is reduced.

    本发明公开了一种智能充放电方法,步骤如下:步骤一:手机APP显示整车信息;步骤二:车主通过APP看到整车信息状态,然后通过APP的4G信号给整车发指令;步骤三:整车接收端通过CAN网络将指令发送至车载充电机和蓄电池系统;步骤四:车载充电机和蓄电池系统根据需要对蓄电池进行智能补电,对动力电池进行智能充电。本发明智能充放电方法能够深度集成OBC和DCDC并可自动功率分配;根据电网用电状态,进行充放电,避开用电高峰期,减少客户使用成本。根据蓄电池状态自动开启DCDC并定时关闭,降低蓄电池馈电无法启动车辆的风险。
