The invention provides an eCVT hybrid power system, and belongs to the technical field of new energy. The eCVT hybrid power system is a hybrid power system adopting a double-motor double-planet two-gear row and is composed of an engine, two motors, a DMCU, two planetary gear systems and a storage battery management system BMS. During use, the BMS monitors module voltage and temperature of the storage battery pack, is responsible for management of the storage battery pack, including storage battery safety, residual electric quantity SOC calculation, charging and discharging process control, parameter monitoring, high-voltage safety of a power assembly, fault code feedback to the HTCU, handshake with a ground charging pile, identification, and confirmation processes, and the HTCU is responsible for fault diagnosis. According to the eCVT hybrid power system, the voltage, the temperature, the charging and discharging process control, parameter monitoring and the like of the storage battery pack are monitored sensitively, the situation that the storage battery pack is damaged is avoided, and the service life of the storage battery pack is prolonged.

    本发明提供了一种eCVT混合动力系统,属于新能源技术领域。该eCVT混合动力系统是采用双电机双行星两档位排的混合动力系统,由发动机、两个电机、DMCU、两套行星齿轮系统和蓄电池管理系统BMS组成。使用时,蓄电池管理系统BMS监测蓄电池组的模块电压和温度,负责对蓄电池组进行管理,包括蓄电池安全、残余电量SOC计算、充放电过程控制、参数监测,负责动力总成的高压电安全,并反馈故障码给HTCU,负责与地面充电桩的握手、识别、确认过程,实现外接充电功能,该eCVT混合动力系统对蓄电池组的电压、温度、充放电过程控制、参数监测等监测灵敏,避免蓄电池组损伤的情况,提高了蓄电池组的使用寿命。
