The invention discloses a rail engineering vehicle power battery charging control system and method, and the system comprises a central control unit, and a power battery management unit, a transmission control unit, an engine control unit and a charging main circuit which are connected with the central control unit. The charging main circuit comprises a generator set unit, a controllable rectification unit, a charging and discharging unit, an intermediate direct current unit, a traction inversion unit and an asynchronous traction motor which are sequentially connected in series, and a power battery connected with the charging and discharging unit. The central control unit obtains target charging power according to first allowable charging power, transmitted by the engine control unit, of the generator set unit and second allowable charging power transmitted by the power battery management unit, and the transmission control unit controls the controllable rectifying unit and the charging and discharging unit to charge the power battery according to the target charging power. The power battery can be charged during driving or parking in the engine mode, and the problem that the power battery cannot be charged due to the absence of a ground charging pile is solved.

    本发明一种轨道工程车动力电池充电控制系统及方法,系统包括:中央控制单元、与中央控制单元连接的动力电池管理单元、传动控制单元、发动机控制单元以及充电主电路,充电主电路包括:依次串联的发电机组单元、可控整流单元、充放电单元、中间直流单元、牵引逆变单元和异步牵引电机、以及与充放电单元连接的动力电池,中央控制单元根据发动机控制单元传输的发电机组单元的第一允许充电功率以及动力电池管理单元传输的第二允许充电功率获取目标充电功率,传动控制单元根据目标充电功率控制可控整流单元和充放电单元对动力电池进行充电。本发明能够实现发动机模式下行车或停车时均可向动力电池充电,避免了因无地面充电桩无法向动力电池充电的问题。
