Abstract

The present invention provides a battery pack heat exchange system and an electric vehicle, pertaining to the technical field of new energy sources. The battery pack heat exchange system comprises multiple heat exchange devices, a total water inlet pipe and a total water outlet pipe. The multiple heat exchange devices are arranged corresponding to multiple batteries in a battery pack one by one, and each heat exchange device comprises a water inlet and a water outlet. The multiple water inlets are all connected with the total water inlet pipe, and the multiple water outlets are all connected with the total water outlet pipe, so that the multiple heat exchange devices are connected in parallel. Each heat exchange device is arranged under each single battery, the multiple heat exchange devices are connected in parallel, and when the heat exchange is needed, each heat exchange device performs heat exchange independently, so that the mutual contamination between the heat exchange devices is reduced, and the heat exchange of the battery pack is more even. The electric vehicle comprises the battery pack heat exchange system. The battery pack heat exchange system and the electric vehiclecan solve the technical problem of uneven temperature control among single batteries in the battery pack.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a heat exchange system for a battery pack and an electric vehicle. Background technique [0002] Although the electric vehicle industry has developed rapidly in recent years, there are still major hidden dangers behind it, among which problems such as insufficient cruising range of electric vehicles, poor user experience in summer / winter extreme weather, and insufficient lifespan are still prominent. To solve the above problems, it is necessary to focus on the perspective of the battery system. [0003] As one of the most important components of the battery system, the thermal management system's performance is closely related to the mileage, safety performance and service life of electric vehicles. Due to the particularity of existing lithium batteries, their use (discharge) range is generally limited to -20 to 60°C (except for batteries for special applications), and the...
