CHARGER COOLING SYSTEM CONTROL METHOD AND CONTROLLER FOR GREEN CAR

摘要

The present invention relates to a method to control a charger cooling system for an environmental vehicle. Since a cooling system controller (1) executes a predicted temperature rise-based cooling control mode to enable the cooling system controller (1) detecting a charging operation state of a charger (10), to operate a cooling fan (30) or electric water pump (20) at a calculated temperature rise prediction value until a residual charge completion time of a main battery (10-1), the present invention is capable of optimizing cooling efficiency even if the frequency of the operation of the cooling fan (30) and the electric water pump (20) is reduced to a charging current-based temperature rise prediction value besides temperature information of the charger, sensed in real time, and especially, the reduction in the operation of the cooling fan (30) and the electric water pump (20) enables low noise and reduces energy consumption.
