Battery module for hybrid electric vehicle and battery pack thereof

Abstract

The invention discloses a battery module for a hybrid electric vehicle. The battery module comprises at least two electrically connected battery rods and a clamp hoop, wherein the clamp hoop uses a duplex clamp hook; the duplex clamp hoop comprises two duplex clamp hoop sub bodies; each duplex clamp hoop sub body comprises two clamp hoop sub bodies with mutually connected outer walls; a position clamping buckle and a position clamping block which are anastomotic with each other are arranged on the duplex clamp hook body; the two duplex clamp hook sub bodies are connected through buckling the position clamping buckles and the position clamping blocks; the two clamp hook sub bodies form a clamp hook monomer; a battery monomer is fixed in the clamp hook monomer. The invention also discloses a battery pack using the battery module. The battery module and the battery pack provided by the invention have the characteristics that the structure is reasonable; the space utilization rate is high; the heat radiation performance is good.

Description

technical field [0001] The invention relates to a power supply technology for a hybrid electric vehicle, in particular to a battery module and a battery pack for a hybrid electric vehicle. Background technique [0002] In recent years, as people pay more attention to issues such as air quality and the earth's oil resource crisis, pure electric vehicles, plug-in hybrid vehicles, hybrid vehicles and other new energy vehicles that can achieve energy saving and emission reduction have developed rapidly. The power battery is a key component of a hybrid electric vehicle, and its performance will directly affect the performance of the vehicle. Ni-MH power batteries have become the preferred power source for hybrid vehicles due to their high specific power, good low-temperature performance, excellent high-current discharge performance, long cycle life, no pollution to the environment, and high safety. [0003] Compared with pure electric vehicles, hybrid vehicles are more convenien...

AI Technical Summary

Problems solved by technology

At present, most of the battery modules and battery packs are fixed by external brackets. The fixing between battery modules is relatively simple, and the fixation is not firm. Due to frequent vibrations, the battery pack may become loose or even the connecting piece may fall off.

Moreover, the assembly method and space utilization of the currently used battery packs are unreasonable, and the heat dissipation of the assembled battery packs is not ideal.
