The invention discloses a battery system circuit convenient for echelon utilization and battery replacement, which comprises a battery pack, the battery pack comprises a power battery and a battery management system connected with a power supply, and the battery management system is used for monitoring the use state of the battery; a multi-pack parallel system is adopted, each battery subsystem can independently supply power to the whole vehicle, under the condition that not all packs are abnormal, the vehicle can be ensured to run by switching a power supply mode, and the battery packs are connected with a high-voltage box through a quick-change connector and are indirectly connected with the whole vehicle at the same time; the battery pack is also connected with a high-voltage box; the high-voltage box is used for vehicle integrated power distribution. According to the invention, charging and battery replacement design is considered, so that the battery system can still adapt to the charging gun base for charging after being separated from the battery replacement station, and the charging scene of the battery-replaceable battery system vehicle is expanded. And therefore, service can be better provided for echelon utilization according to the actual situation, the use safety is improved, and the safety risk is reduced.

    本发明公开了一种便于梯次利用和换电的电池系统电路,包括电池包,电池包内包括动力电池以及与电源连接的电池管理系统,电池管理系统用于监控电池的使用状态;采用多包并联系统且每个电池子系统又可独立为整车供电,非所有包出现异常的情况下,车辆可通过切换供电模式来确保车辆行驶,电池包经快换连接器实现与高压盒连接同时间接的完成与整车间连接;电池包还连接有高压盒;高压盒用于整车集成配电。本发明的兼顾充电和换电设计,使得电池系统在脱离换电站后仍能够适应充电枪座进行充电,拓展了可换电电池系统车辆的充电场景。使得可以根据其实际情况更好的为梯次利用服务,增加使用安全,降低安全风险。
