The invention discloses a battery pack, a grid-connected management method, electric energy equipment and an energy storage system, the battery pack comprises a battery, a vehicle-mounted charger, an alternating current interface and a battery management system, and the battery is used for providing direct current; the battery is connected with the alternating current interface through the vehicle-mounted charger; the vehicle-mounted charger is used for converting direct current of the battery into alternating current or converting alternating current transmitted by the alternating current interface into direct current; and the battery management system is connected with the battery and the vehicle-mounted charger. According to the technical scheme, the vehicle-mounted charger is integrated in the battery pack, and after the battery pack is decommissioned, the vehicle-mounted charger can replace an energy storage inverter to convert alternating current and direct current and communication protocols between the battery pack and the energy storage power station; therefore, the problem that different battery packs can be connected to the energy storage power station only by using different energy storage inverters is solved.

    一种电池包、并网管理方法、电能设备以及储能系统,电池包包括电池、车载充电机、交流接口以及电池管理系统,电池用于提供直流电流;电池通过车载充电机与交流接口相连接;车载充电机用于将电池的直流电流转化为交流电流,或将交流接口传递的交流电流转化为直流电流;电池管理系统与电池和车载充电机相连接。本申请技术方案通过将车载充电机集成于电池包内,当电池包退役后,车载充电机能够代替储能逆变器,对电池包与储能电站之间的交直流和通讯协议进行转化,从而解决不同的电池包需要使用不同的储能逆变器才能接入储能电站的问题。
