Abstract

The invention belongs to the technical field of charging of new energy vehicles, and particularly relates to a liquid cooling charging system for a new energy vehicle and a control method. The systeminvolves a charging socket, a water pump, a water inlet pipe, a water outlet pipe, a connecting water pipe, a heat dissipation water tank, a power distribution unit and a safety monitoring box, wherein the water pump and the heat dissipation water tank are connected through the connecting water pipe, the water inlet pipe is arranged at the end, away from the connecting water pipe, of the water pump, and the water outlet pipe is arranged at the end, away from the connecting water pipe, of the heat dissipation water tank. According to the liquid cooling charging system for the new energy vehicleand the control method, through the reasonable structural arrangement, the cooling effect of the liquid cooling charging system is effectively improved; through temperature sensors arranged on a charging liquid cooling terminal and a liquid cooling terminal, temperature monitoring is carried out, and the safety of the charging process is guaranteed; and meanwhile, through the arrangement of a cooling liquid insulation detection module, the insulation failure problem due to the long-term use of cooling liquid is avoided.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicle charging, and in particular relates to a liquid-cooled charging system and a control method for new energy vehicles. Background technique [0002] With the rapid development of global industry, the ecological environment is being destroyed day by day, and environmental protection issues are gradually put on the agenda. Exhaust emissions from automobiles account for most of the environmental pollution. If we want to promote environmental protection, we must solve the problem of exhaust emissions from traditional automobiles. For this reason, due to the use of advanced technology, new energy vehicles have effectively achieved low-carbon and environmentally friendly travel, and have been widely promoted. [0003] In recent years, in the process of practical application and promotion of new energy vehicles, the two main factors affecting the development of electric vehicles are driving ran...
