Abstract

The invention discloses a battery module for a vehicle. The battery module for the vehicle comprises a battery assembly, a micro-channel parallel flow heat exchanger, electric heating parts and a temperature equalizing plate, wherein the micro-channel parallel flow heat exchanger is arranged at the top and / or bottom of the battery assembly and comprises a first flow collecting pipe, a second flow collecting pipe and a plurality of flat pipes; the two ends of the flat pipes are connected with the first flow collecting pipe and the second flow collecting pipe respectively; the plurality of flat pipes are distributed at intervals in the axial direction of the flow collecting pipes; the electric heating parts are arranged on the sides, departing from the battery assembly, of the flat pipes; and the temperature equalizing plate is arranged between the battery assembly and the micro-channel parallel flow heat exchanger. The battery module for the vehicle, provided by the invention, has simple structure, high heat exchange efficiency and high working reliability.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a battery module for vehicles. Background technique [0002] Compared with the pure electric power system, the discharge rate of the extended-range power system is higher, and more secondary heat is generated during operation, while the life and performance of the power battery system are greatly affected by its temperature, so the requirements for the heat dissipation system are higher. On the other hand, as the only power source needs to maintain good performance at low temperature, the thermal management system needs to ensure that the temperature of the battery core is within a reasonable range in the low temperature environment. The current active management system is either inefficient and unable to meet the requirements of the extended-range system, or the system structure is complex and cannot meet the requirements of system integration and light weight, and the...
