The invention provides a vehicle, an energy balancing device and a balancing method thereof.The energy balancing device comprises a battery pack, a bridge arm unit, an energy storage module, a switch module and a control module, and when a first battery pack and a second battery pack are in an unbalanced state, a first power switch unit and a second power switch unit are controlled to be switched on alternately; and enabling the energy storage module to be in an alternate energy storage and release process until the first battery pack and the second battery pack are in a balanced state. According to the technical scheme, only devices in an existing circuit need to be used, an equalization circuit does not need to be additionally arranged, the energy storage module serves as an energy equalization medium, the energy output by the high-energy one of the first battery pack and the second battery pack is stored firstly, and then the energy is released to the low-energy one of the first battery pack and the second battery pack; therefore, the first battery pack and the second battery pack are balanced, the balancing speed is high, energy consumption is not needed, meanwhile, a transformer circuit does not need to be added, and the size and the cost of a product are reduced.

    本申请提供一种车辆、能量均衡装置及其均衡方法,能量均衡装置包括电池包、桥臂单元、储能模块、开关模块以及控制模块,当第一电池组和第二电池组处于不均衡状态时,控制第一功率开关单元和第二功率开关单元交替导通,使储能模块处于交替储能和释能过程中,直至第一电池组与第二电池组处于均衡状态。本申请技术方案仅需要使用现有电路中的器件,无需额外增加均衡电路,将储能模块作为能量均衡的中介,先存储第一电池组和第二电池组中能量较高者输出的能量,再将能量释放给第一电池组和第二电池组中能量较低者,进而实现第一电池组与第二电池组的均衡,均衡速度快,不需要进行能量消耗,同时不需要增加变压器电路,降低了产品的体积和成本。
