Problems solved by technology

The conductor can be overloaded with multiple times of current through the heat dissipation of the liquid cooling system, but the abnormal operation of the liquid-cooled high-power charging device cannot be detected in time, which will cause the liquid-cooled high-power charging device to burn out due to the insufficient current-carrying capacity of the conductor itself

Abstract

The invention discloses a liquid cooling high-power charging device and a monitoring method of the liquid cooling high-power charging device. The liquid cooling high-power charging device comprises charging cables, a charging controller and a cooling system. One end of each charging cable is connected with a charging gun. Each charging gun is provided with a thermal sensor. The cooling system comprises an oil tank, an oil pump and a heat dissipater, the oil tank, the oil pump and the heat dissipater are connected with the charging cables through pipelines, and a cooling loop is formed. The thermal sensors are connected with the charging controller and used for detecting the working temperatures of two terminals of the charging guns. The charging controller judges whether the working temperatures are larger than a first preset temperature threshold value or not, and if the working temperatures are larger than the first preset temperature threshold value, charging current is reduced to the preset current range or charging is stopped. By the adoption of the technical scheme, the reliability of the liquid cooling high-power charging device can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid-cooled high-power charging, in particular to a monitoring method for a liquid-cooled high-power charging device and a liquid-cooled high-power charging device. Background technique [0002] With the maturity of electric vehicle technology, the occupancy rate of electric vehicles is gradually increasing. When the battery power of the electric vehicle is low, it needs to go to a special power station for charging. [0003] When charging, connect the two main power cables of the charging station to the car, and start charging after the power is turned on. The current during car charging is very high, which can easily heat up the cables or charging equipment. For this reason, in the prior art, a liquid cooling circuit is provided in the cable to absorb the heat in the charging process, reduce the temperature rise in the charging process, and dissipate heat in time. The conductor can be overloaded wi...
