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.
