Cooling System of DC Charging Piles and Ventilation Control Strategy
This paper clarifies the problem observed in the cooling system of charging piles,and outlines the new solution proposed.The 180 kW charging pile is modeled by the virtual simulation platform Flow Simulation,and the test environ-ment is also configured.By comparing the number of fans obtained from simulation and test,the flaws in the product de-sign and the potential improvement scheme are pointed out.The temperature rise of charging pile after applying the pro-posed control strategy is compared with that of a single rectifier module,thereby verifying the feasibility of the scheme.
