The invention discloses an electric loader cooling control system and a control method, and belongs to the technical field of electric loaders. Comprising a cooling unit and a PDU power distribution system used for controlling the cooling unit, the cooling unit is communicated with a cab cooling pipeline and a battery cooling pipeline, the PDU power distribution system comprises a PDU control module, and the PDU control module is connected with a control unit positive relay, a pre-charging resistor and a unit pre-charging relay. The pre-charging resistor and the unit pre-charging relay are connected in series and then are connected in parallel with the unit positive relay, and are used for preventing high-voltage components from being damaged due to excessive instantaneous current when high voltage is applied. And a TMS is arranged in the cooling unit. According to the system, after the cooling unit is powered on through the PDU power distribution system, the TMS controls the cooling unit to work, the cab and/or the battery can be cooled separately or simultaneously, and compared with a traditional mode that the cab and the battery are cooled separately through two cooling systems, the structure is simpler, and the cost is lower.

    本发明的一种电动装载机冷却控制系统及控制方法,属于电动装载机技术领域。包括冷却机组和用于控制冷却机组的PDU配电系统,冷却机组分别连通驾驶室冷却管路和电池冷却管路,PDU配电系统包括PDU控制模块,PDU控制模块分别连接控制机组正继电器、预充电阻和机组预充继电器,预充电阻和机组预充继电器串联后与机组正继电器并联,用于在上高压时防止瞬间电流过大顺坏高压部件。冷却机组内设有TMS。系统通过PDU配电系统对冷却机组进行上电后,TMS控制冷却机组工作,可以分别或同时对驾驶室和/或电池进行冷却,相对于传统的两套冷却系统分别对驾驶室和电池进行冷却,结构更加简单且成本更低。
