Abstract

The invention discloses a thermal l management system of a commercial vehicle power battery. The thermal management system comprises a battery liquid-cooling system, a heat dissipation system and a heating system, wherein the battery liquid-cooling system comprises an ethylene glycol aqueous solution circulation system and a refrigerant circulation system, the ethylene glycol aqueous solution circulation system comprises a compensation water tank, a power battery and a first water pump, and the refrigerant circulation system comprises an expansion valve, a condenser and a compressor. The additionally-arranged heat dissipation system is connected in parallel with an engine cooling system outside an intelligent cooling management system, and an air suction type electronic fan of the intelligent cooling management system is used for blowing air and cooling; and compared with an original system, the novel power battery thermal management system has the advantages of relatively small change and more energy saving, and the battery temperature difference can be more uniform.

Description

technical field

[0001] The invention relates to a battery thermal management system, in particular to a commercial vehicle power battery thermal management system. Background technique

[0002] As the global energy crisis and environmental problems are intensifying, the traditional automobile industry is facing unprecedented severe challenges; the world's major automobile producing countries have accelerated deployment, taking the development of electric vehicles as a national strategy, accelerating technology research and development and industrialization, and vigorously Develop and promote the application of automotive energy-saving technologies; the power battery pack generates a lot of heat during the operation of the car, and if the heat is not dissipated in time, the temperature of the battery pack will rise; too high or too low temperature will not only reduce the use efficiency and cycle of lithium batteries The life of the system may also lead to permanent failure o...
