The invention discloses an electric quantity equalization method and equalization system for battery packs in train carriages, a train and a central control unit, the method comprises the following steps: acquiring battery pack information in each carriage, the battery pack information comprising battery pack electric quantity and maximum allowable discharge power; when it is determined that the train needs to be subjected to electric quantity equalization according to the electric quantity of the battery pack in each compartment, the actual allowable discharge power of the battery pack needing to be subjected to electric quantity equalization is obtained according to the electric quantity of the battery pack in each compartment and the maximum allowable discharge power of the battery pack needing to be subjected to electric quantity equalization; and performing limited power control on the motor in the corresponding compartment according to the actual allowable discharge power of the battery pack needing to be subjected to electric quantity equalization so as to realize electric quantity equalization of the battery pack in each compartment. According to the control method, balance control can be effectively carried out on the electric quantity of each battery pack, so that the train is in a balanced state, and the situation that operation of the train is affected by insufficient electric quantity due to excessive discharge of a single or multiple battery packs is avoided.
本发明公开了一种列车车厢内电池包的电量均衡方法和均衡系统、列车和中央控制单元,所述方法包括:获取各个车厢内的电池包信息,其中,电池包信息包括电池包电量和最大允许放电功率;根据各个车厢内的电池包电量确定列车需要进行电量均衡时,根据各个车厢内的电池包电量和需要进行电量均衡的电池包的最大允许放电功率获取需要进行电量均衡的电池包的实际允许放电功率;根据需要进行电量均衡的电池包的实际允许放电功率对相应车厢内的电机进行限功率控制,以实现各个车厢内的电池包的电量均衡。本发明的控制方法,能够有效地对各电池包电量进行均衡控制,使列车处于平衡状态,保证列车不会出现因单个或多个电池包放电过多电量不足影响运行的情况。
