Abstract

The invention relates to a vehicle-mounted battery charger which comprises a charger module used for charging a battery system. The vehicle-mounted battery charger further comprises a heat transfer plate and a heater. The heat transfer plate is in series connection with a heating cycle loop of the battery system. The heater is connected with an output end of the charger module. The charger module or the battery system supplies a power source to the heater through the output end. A flow channel is contained in the heat transfer plate and the heat transfer plate is connected with the heater. The heat transfer plate exchanges heat generated by the heater with refrigerant fluid in the heating cycle loop through the flow channel. According to the technical scheme, a high-voltage liquid heater need not be independently installed, the cost of an overall vehicle is reduced and the arrangement complexity of the overall vehicle is reduced. The invention further provides a battery liquid cooling system which reduces the system cost and decreases the system structure. The invention further provides the electric vehicle. The overall vehicle is lower in cost and smaller in arrangement complexity.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an on-board charger, a battery liquid cooling system and an electric vehicle. Background technique [0002] As countries pay more and more attention to energy conservation and environmental protection, the electrification of traditional fuel vehicles has become the mainstream direction of automotive technology development. As one of the main core "three electrics" of electric vehicles, power batteries occupy a very important position. In terms of thermal management, the use of battery liquid cooling methods that can adapt to all-weather environments has gradually become the mainstream of technology. In order to realize the heating function of the liquid-cooled battery and improve the charging and discharging performance of the battery in a cold environment, an independent high-pressure liquid-cooled heater is generally equipped to heat the battery system by heating the...
