The invention relates to a dual hybrid battery pack suitable for motor driving equipment, and belongs to the technical field of hybrid batteries. The dual hybrid battery pack comprises a hybrid battery pack, a secondary battery pack, a battery pack management system (PMS) and a battery management system (BMS), wherein the hybrid battery pack is composed of two or more hybrid batteries; each hybridbattery is formed by combining a secondary battery and a storage battery; the secondary battery is an energy storage device composed of a plurality of battery packs; each battery pack is composed ofa plurality of battery cells; the secondary battery pack comprises two or more secondary batteries; the hybrid battery pack and the secondary battery pack are connected in parallel; and thePMSand theBMS are used for controlling so as to use only electricity of the hybrid battery pack when the motor is started and use electricity of the secondary battery pack when the motor is driven. According tothe invention, the rate capability of the battery can be greatly improved, the charging time is shortened, and the battery capacity can be greatly reduced compared with the capacity required by the motor.

    本发明涉及一种适用于马达驱动设备的双重混合电池组,属于混合电池技术领域。本发明包括混合电池组、二次电池组、电池组管理系统PMS和电池管理系统BMS,其中:混合电池组,由两个以上的混合电池构成,混合电池由二次电池和蓄电池组合而成;二次电池,为由若干电池组所构成的能量储存装置,电池组由若干电池芯构成;二次电池组,由两个以上的二次电池构成;混合电池组和二次电池组并联连接;电池组管理系统PMS和电池管理系统BMS,用于控制以便在启动马达时只使用混合电池组的电而驾驶时则使用二次电池组的电。本发明可以大幅提高电池倍率性能而缩短充电时间,且相比于马达所需容量能大幅减少电池容量。
