Abstract

The invention discloses a battery cooling system and an electric bus. The battery cooling system comprises a cooling circuit and a refrigeration circuit which are arranged in parallel. The refrigeration circuit comprises a compressor, a condenser, an expansion valve and a heat exchanger which are sequentially connected in series. The cooling circuit comprises a battery which is connected in serieswith the heat exchanger. The battery cooling system further comprises an exhaust rehydration device arranged in the cooling circuit. The exhaust rehydration device is arranged between the heat exchanger and the battery. The aim of that invention is to solve the cooling problem of the power battery of the electric bus in case of charging and discharging, and the air in the system can be effectively discharged and the battery coolant can be replenished so as to improve the heat exchange efficiency of the cooling system.

Description

technical field [0001] The invention relates to the technical field of battery cooling systems, in particular to a battery cooling system and an electric passenger car using the battery cooling system. Background technique [0002] In recent years, electric buses have become more and more popular, and the working temperature of the power batteries used in them is usually not higher than 60°C. In summer, the outdoor ambient temperature can reach 40°C. At the same time, the charging and discharging process of the battery itself will generate a lot of heat, which will cause the battery temperature to rise sharply, which will not only affect the battery life, but also explode in serious cases. However, the existing battery cooling system generally uses air cooling to reduce the temperature of the battery coolant, which not only has low efficiency, but also cannot remove the air in the system and cannot replenish the liquid in time, thereby affecting the heat exchange efficiency....
