A vehicle including a hybrid battery pack includes a first battery pack and a second battery pack. The first battery pack has a higher energy density than the second battery pack. The second battery pack has a higher power density than the first battery pack. A power inverter module is connected between the hybrid battery pack and a motor generator unit (MGU) that is connected to a powertrain of the vehicle. The power inverter module is configured to regulate power flow between the hybrid battery pack and the MGU. A battery management module is configured to: control switching of the power inverter module; selectively charge and discharge at least one of the first battery pack and the second battery pack; and selectively charge the first battery pack with power from the second battery pack. 一种包括混合电池组的车辆，该车辆包括第一电池组和第二电池组。第一电池组比第二电池组具有更高的能量密度。第二电池组比第一电池组具有更高的功率密度。功率逆变器模块连接在混合电池组和连接到车辆动力系的电动发电机单元(MGU)之间。功率逆变器模块被配置为调节混合电池组和MGU之间的功率流。电池管理模块被配置为：控制功率逆变器模块的切换；选择性地对第一电池组和第二电池组中的至少一个充电和放电；以及利用来自第二电池组的电力选择性地对第一电池组充电。
