The invention relates to a charging and discharging method of a charging trailer, and relates to the technical field of energy storage batteries. Comprising the following steps: determining the electric quantity and address of a first battery module and the electric quantity and address of all second battery modules; when the charging trailer is charged, the first battery module is charged to a preset electric quantity according to the electric quantity and the address of the first battery module; determining a target rechargeable battery module according to the electric quantities and addresses of all the second battery modules; and charging the target rechargeable battery module to preset electric quantity according to the address of the target rechargeable battery module. When the charging trailer discharges, determining a target discharging battery module according to the electric quantity and the address of all the second battery modules; and controlling the target discharge battery module to discharge according to the address of the target discharge battery module until all the second battery modules finish discharging, and controlling the first battery module to discharge according to the address of the first battery module. The problem that the unified charging and discharging mode of each layer of module affects the battery health of each layer of module is solved.

    本申请涉及一种充电拖车的充放电方法,涉及储能电池技术领域。包括以下步骤:确定第一电池模块的电量和地址以及所有第二电池模块的电量和地址。当充电拖车充电时,根据第一电池模块的电量和地址为第一电池模块充电直至预设电量;根据所有第二电池模块的电量和地址,确定目标充电电池模块;根据目标充电电池模块的地址为目标充电电池模块充电至预设电量。当充电拖车放电时,根据所有第二电池模块的电量和地址,确定目标放电电池模块;根据目标放电电池模块的地址控制目标放电电池模块放电,直至所有第二电池模块完成放电后,根据第一电池模块的地址控制第一电池模块放电。解决了各层级模块统一充放电模式对各层级模块的电池健康造成影响的问题。
