Beschreibung
Zusammenfassung:	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
