Embodiment 1

[0019] like figure 1 As shown, the cooling system is a cold air supply system. The cold air supply system provides cold air to the wind-side condenser of the electric vehicle, reduces the working environment temperature of the wind-side condenser, reduces the working pressure of the vehicle-mounted chiller, and improves the working efficiency of the vehicle-mounted chiller, thereby ensuring that the battery of the electric vehicle is in the charging process. Good condition, guaranteed charging speed.

[0020] The cooling capacity of the on-board chiller and the heat generated when the vehicle is running stably are two indicators of vehicle performance that have been determined when the vehicle leaves the factory. According to the matching relationship between the cooling capacity of the on-board chiller and the heating value of the electric vehicle during stable operation, the temperature of the cold air provided by the cold air supply system to the wind side condenser is als...

Embodiment 2

[0025] like figure 2 As shown, the difference from Embodiment 1 is that the cooling system also includes a spray system. The effect of the spraying system on the wind side condenser of the electric vehicle is similar to that of the cold air supply system in Embodiment 1. The difference is that the spray system provides water mist to the condenser of the electric vehicle to reduce the working environment temperature of the condenser on the wind side in the form of spray. According to the matching relationship between the cooling capacity of the on-board chiller and the heating value of the electric vehicle during stable operation, the spray volume provided by the spray system is different. The specific method of use is as follows: when the cooling capacity of the vehicle-mounted chiller is less than 3 times the calorific value when the vehicle is running stably, the method of use is as described in Embodiment 1; when the cooling capacity of the vehicle-mounted chiller is grea...

Abstract

The invention relates to a charging pile system. The charging pile system comprises a charging pile and a cooling system. The charging pile is used for charging an electric vehicle, and the cooling system is used for cooling an air-side condenser of the electric vehicle. By reducing the temperature of the working environment of the air-side condenser, the working efficiency of a vehicle-mounted water chiller set is improved, it is ensured that batteries of the electric vehicle are in a good working state, and thus the battery charging speed is guaranteed.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging pile system. Background technique [0002] When the charging pile is charging the electric vehicle battery, the battery will generate a lot of heat, especially during fast charging, the heat generated by the battery will increase exponentially. Based on the consideration of safety and battery life, the battery temperature should be kept at 25-35°C. Therefore, the battery cooling problem during battery charging becomes the main factor hindering the battery charging speed. However, the cooling capacity of the existing vehicle-mounted chiller has limitations, which cannot meet the requirements for cooling the battery during the fast charging process, thereby reducing the charging speed of the fast charging. The invention provides a charging pile system, which can assist a vehicle-mounted water chiller to cool the battery of an electric vehicle to ensure charging ...
