Battery module for new energy electric vehicle

The utility model discloses a battery module for a new energy electric vehicle. The battery module comprises a module shell and a battery core assembly positioned in the module shell, the module shell comprises a top cover, a bottom plate and a module heat conducting plate, and the module heat conducting plate is provided with a wave-shaped buffer structure; the module heat conduction plate is filled with a working medium used for heat conduction. According to the battery module provided by the utility model, the module heat-conducting plate is arranged, so that on one hand, the module has certain elastic change in height dimension due to the fact that the module heat-conducting plate is provided with the wave-shaped buffer structure, and the battery module is self-adaptive to the height dimension change of the module caused by the thickness change in the charging and discharging and life cycle of the battery core; and on the other hand, the working medium for heat conduction is filled in the module heat cond
