The invention provides a high-voltage-class charger system and a control method. The system comprises a parallel power distribution module, a series power distribution module and all charging modules in a preset charger system to be transformed, the parallel power distribution module is respectively connected between positive electrodes of at least two charging modules in a preset charger system and between negative electrodes of the at least two charging modules so as to control the at least two charging modules to be connected in parallel or disconnected; the series power distribution modules are connected between the positive electrodes and the negative electrodes of the at least two charging modules respectively so as to control the at least two charging modules to be connected in series or disconnected. According to the invention, the charging module with relatively high cost in the preset charger system to be transformed does not need to be replaced, the transformation difficulty can be reduced while the transformation cost is reduced, and the transformed high-voltage-grade charger system is obtained through a simple and practical method.
本发明提供一种高电压等级充电机系统及控制方法。该系统包括:并联配电模块、串联配电模块和待改造的预设充电机系统中的所有充电模块;并联配电模块分别连接在预设充电机系统中的至少两个充电模块的正极之间和该至少两个充电模块的负极之间,以控制该至少两个充电模块并联或断开;串联配电模块分别连接在该至少两个充电模块的正极和负极之间,以控制该至少两个充电模块串联或断开。本发明无需更换待改造的预设充电机系统中成本较高的充电模块,可以在降低改造成本的同时,降低改造难度,通过简单实用的方法得到改造后的高电压等级充电机系统。
