The invention discloses a bidirectional charging and discharging type portable battery replacing method and system. The method comprises the steps that an electric vehicle obtains the electric quantity of an electric vehicle battery and the electric quantity of a portable battery through a controller or a battery management system; and the portable battery charges the electric vehicle battery or the electric vehicle battery charges the portable battery according to the electric quantity of the electric vehicle battery and the electric quantity of the portable battery. Through the bidirectional DC/DC converter, the portable battery can supplement electricity to the electric vehicle battery, operation feedback energy of the electric vehicle can be stored to the portable battery in reverse, and energy consumption is avoided. Meanwhile, the portable battery can be charged while the battery of the electric vehicle is charged in the charging process, so that the utilization rate of the portable battery is further improved.

    一种双向充放电的可携电池换电方法及系统,所述方法包括:电动车通过控制器或电池管理系统获取电动车电池和可携电池的电量;电动车根据电动车电池和可携电池的电量,使可携电池向电动车电池充电或电动车电池向可携电池充电,本申请通过双向DC/DC变换器,既可以使可携电池给电动车电池补电,也可以反过来将电动车的运行回馈能量存储到可携电池上,避免了能量的浪费,同时在充电过程中给电动车电池充电的同时,也能够给可携电池充电,进一步提高可携电池的利用率。
