Abstract

The invention discloses a battery pack temperature adjusting method and device of a new energy refrigerator car and the new energy refrigerator car. The method comprises: acquiring current temperatureof a battery pack; if the current temperature is lower than a first threshold value, controlling a heat exchange unit to heat the battery pack; and if the current temperature is higher than a secondthreshold value, controlling a heat exchange unit to cool the battery pack, wherein the heat exchange unit is adjacent to the battery pack. According to the invention, the battery pack can be always kept in a stable working temperature range, and the charging and discharging performance and stability of the battery pack are ensured.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a method and device for adjusting the temperature of a battery pack of a new energy refrigerated vehicle, and a new energy refrigerated vehicle. Background technique [0002] Refrigerated trucks are mainly used as transportation carriers for refrigerated, frozen and fresh-keeping foods, such as agricultural products, poultry meat, aquatic products, quick-frozen foods, special medicines, etc., which need to be kept at the best low temperature during storage and transportation. New energy refrigerated vehicles are generally closed vans, and their refrigeration systems are directly powered by battery packs, while traditional refrigerated vehicles are driven by engines, which have low energy efficiency and serious environmental pollution. In recent years, my country has increased preferential measures for new energy vehicles to encourage the vigorous development of new energy s...
