The invention relates to the technical field of new energy automobiles, in particular to a power battery pack, a vehicle and a method, the power battery pack comprises a first electricity storage assembly and a second electricity storage assembly, and the first electricity storage assembly and the second electricity storage assembly are both used for storing and releasing electricity. The first electricity storage assembly and the second electricity storage assembly can be mutually charged and discharged, and the electricity stored by the first electricity storage assembly is larger than the electricity stored by the second electricity storage assembly; the controller is used for controlling the first electricity storage assembly and/or the second electricity storage assembly to store electricity generated by energy recovery in the vehicle energy recovery process and controlling the first electricity storage assembly and/or the second electricity storage assembly to release electricity in the vehicle driving process so as to provide driving energy. Therefore, the problem that the service life of the power battery pack is shortened due to insufficient recycling capacity of the power battery in a high-electric-quantity state and insufficient discharging capacity of the power battery in a low-electric-quantity state in the prior art is solved.

    本申请涉及新能源汽车技术领域,特别涉及一种动力电池包、车辆及方法,其中,动力电池包包括第一储电组件和第二储电组件,其中,第一储电组件和第二储电组件均用于存储电量和释放电量,第一储电组件和第二储电组件之间可相互充电与放电,且第一储电组件存储的电量大于第二储电组件存储的电量;控制器,用于在车辆能量回收过程中,控制第一储电组件和/或第二储电组件存储能量回收产生的电量,并在车辆驱动过程中,控制第一储电组件和/或第二储电组件释放电量,以提供驱动能量。由此,解决了相关技术中动力电池在高电量状态下回收能力不足、低电量状态下放电能力不足,导致动力电池包的寿命缩减等问题。
