A battery management system for an electric vehicle includes a high voltage battery, a low voltage battery, and a bidirectional converter. The bidirectional converter is configured to connect the high voltage battery to the low voltage battery and generate a power flow between the high voltage battery and the low voltage battery. The bidirectional converter is further configured to monitor a first voltage associated with the high-voltage battery and a second voltage associated with the low-voltage battery, and to control a voltage ratio of the first voltage to the second voltage to be maintained in a predetermined range by controlling a power flow between the high-voltage battery and the low-voltage battery.
本发明涉及一种用于电动车辆的电池管理系统,该电池管理系统包括高电压电池、低电压电池和双向转换器。双向转换器被配置为将高电压电池连接到低电压电池,并且在高电压电池与低电压电池之间生成功率流。双向转换器进一步被配置为监视与高电压电池相关联的第一电压和与低电压电池相关联的第二电压,并且通过控制高电压电池与低电压电池之间的功率流,来控制第一电压与第二电压的电压比保持在预定范围中。
