Abstract
本申请提供的一种充放电均衡控制方法、电池组件及用电系统。电池组件包括M个电池模块，M个电池模块并联连接，M为大于1的正整数；每个电池模块包括：控制单元、DCDC转换器和储能单元，控制单元与DCDC转换器电连接，DCDC转换器还与负载和/或供电源电连接；针对每个电池模块，该方法包括：控制单元确定功率参数的参考值，参考值用于实现M个电池模块均衡充放电；控制单元通过DCDC转换器控制功率参数的实际值等于参考值。从而，实现了M个电池模块的均衡充放电，还实现了电池组件中不同容量的电池模块并联并功率，解决了相关技术中由于电池模块并联使用而对各个电池模块中的电芯包的一致性要求较高的问题。
