Abstract

The invention discloses a battery module and a light logistics vehicle. The battery module comprises a battery cell assembly, a shell and a heating assembly, wherein the battery cell assembly comprises a plurality of battery cells stacked up and down; an opening is formed in one side of the shell; the heating assembly is arranged at the opening of the shell, an accommodating space is defined by the heating assembly and the shell, the battery cell assembly is accommodated in the accommodating space, the heating assembly comprises a heating film, an insulating sheet and a heat conducting plate arranged between the heating film and the insulating sheet, and the insulating sheet covers the side, which deviates from the opening, of the battery cell assembly; and the heating film is used for heating the heat conducting plate, and the battery cell assembly is heated through the insulating sheet. According to the invention, the battery cell assembly of the battery module is formed by stackingbattery cells, the capacity of the battery module is improved, the battery cell assembly adopts a mode of heating by the heating film, and the transverse width of the battery module is reduced, so that the battery module meets the arrangement requirement of the light logistics vehicle in the width direction, and the battery module which is low in cost, safe, high in capacity and large in size canbe applied to the light logistics vehicle.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a battery module and a light logistics vehicle. Background technique [0002] There are mainly two types of battery modules used in new energy vehicles in the prior art. One is a cylindrical battery, which mainly uses serpentine flat tubes for heat dissipation, so as to better maintain the working temperature of the battery and prolong the service life of the battery. However, the cost of liquid cooling configuration for cylindrical batteries is relatively high, and the size of the cells is small. If it is used in a light logistics vehicle, the number of cells with a large current such as 90-100kwh is large, and the serial and parallel connection method is complicated, resulting in the price of the liquid cooling system. High, not suitable for low-cost and safe use of light logistics vehicles; [0003] Another type of large square battery is mainly used in large vehicles such ...
