The invention relates to the technical field of storage battery pack charging, in particular to a quick charging control method and system for a multi-branch storage battery pack. The method comprises the following steps: S1, calculating the residual power in a corresponding charging mode according to the working condition of locomotive operation; S2, calculating the total charging supply current; S3, calculating the maximum allowable charging total current of all traction storage battery branches; S4, comparing the charging supply total current with the maximum allowable charging total current of all traction storage battery branches; S5, if the total charging supply current meets the total current of all the traction storage battery branches, carrying out charging according to the maximum allowable charging current of each traction storage battery branch; and S6, if the total current of all the traction storage battery branches is not enough to meet the total current of all the traction storage battery branches, distributing the charging supply total current in proportion, and charging the traction storage batteries by all the traction storage battery branches according to the distributed charging current. According to the invention, the charging current can be reasonably distributed to each charging control branch, and rapid charging is realized.
本发明涉及蓄电池组充电技术领域,更具体的说,涉及一种多支路蓄电池组快速充电控制方法及系统。本方法包括以下步骤:S1、根据机车运行的工况,计算对应充电模式下的剩余功率;S2、计算充电供给总电流;S3、计算所有牵引蓄电池支路最大允许充电总电流;S4、比较充电供给总电流和所有牵引蓄电池支路最大允许充电总电流;S5、如果充电供给总电流满足所有牵引蓄电池支路总电流时,则按照各个牵引蓄电池支路的最大允许充电电流进行充电;S6、如果不足以满足所有牵引蓄电池支路总电流时,将充电供给总电流按比例进行分配,各个牵引蓄电池支路按照分配的充电电流对牵引蓄电池进行充电。本发明能给各个充电控制支路合理分配充电电流,实现快速充电。
