Abstract

The invention relates to a battery module, a power battery pack and an automobile. The battery module comprises a plurality of middle separation plates which are stacked along the left-right directionof the battery module, a plurality of single batteries, a mounting plate arranged at the front side of the battery module and a draught fan fixed on the mounting plate, wherein middle heat dissipation air plates are arranged on the middle separation plates; middle heat dissipation air channels which are through along the front-rear direction are formed in the middle heat dissipation air plates; left side faces of the middle heat dissipation air plates are subjected to heat exchange with right side surfaces of the single batteries at the left side; right side faces of the middle heat dissipation air plates are subjected to heat exchange with left side surfaces of the single batteries at the right side; each middle heat dissipation air channel is provided with a first air opening and a second air opening; a chamber is arranged between a mounting plate and a front end face of each single battery; the first air openings are communicated with the chambers and the second air openings are formed in the rear side of the battery module and are communicated with the outer part of the battery module. The battery module provided by the invention is high in heat dissipation efficiency and theheat dissipation problem in a rapid charge / discharge process (3C to 6C high-rate charging and discharging) is solved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a battery module, a power battery pack and a vehicle. Background technique [0002] The power battery pack is an energy supply device for new energy vehicles. Usually, the power battery pack is composed of multiple side-by-side battery modules, and each battery module is composed of multiple single cells stacked. [0003] When the battery module is charged and discharged, heat will be generated. If the heat is not discharged in time, it will affect the performance of the battery module and even cause danger. The heat dissipation of the battery module usually includes air cooling and water cooling. [0004] The existing air-cooled heat dissipation solutions for battery modules are as follows: [0005] (1) An air-cooled heat dissipation plate is placed at the bottom of the battery module. The single battery is only in contact with the heat dissipation plat...
