Embodiment Construction

[0026] Next, the technical solutions in the embodiments of the present invention will be described in the following examples, and the described embodiments are merely, not all of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.

[0027] It should be noted that if there is a directional indication (such as above, lower, left, right, post, after, after, after, after, after ...), the directional indication is only used to interpret a particular attitude (such as the figures. Sign) The relative positional relationship between the components, the movement condition, etc., if the specific posture changes, the directional indication is also correspondingly changed.

[0028] Further, in the embodiment of the present invention relates to a "first", "second", the description, "first", "second", and the like are used only for the purpose of descript...

Abstract

The invention discloses a battery module and a light logistics vehicle. The battery module includes: a battery cell assembly, a housing and a heating assembly. The battery cell assembly includes a plurality of battery cells stacked up and down; one side of the housing has an opening; The heating assembly is arranged at the opening of the housing, and is enclosed with the housing to form an accommodation space, the cell assembly is accommodated in the accommodation space, and the heating assembly includes a heating film, an insulating sheet, and a heat conduction film arranged between the heating film and the insulating sheet. The insulating sheet is covered on the side of the cell assembly away from the opening; the heating film is used to heat the heat conducting plate, and the cell assembly is heated through the insulating sheet. The cell assembly of the battery module of the present invention is formed by stacking cells, and the lifting The capacity of the battery module is increased, and the battery module is heated by a heating film, which reduces the lateral width of the battery module, so that the battery module can meet the layout requirements of light logistics vehicles in the width direction, and achieve low-cost and safe large-scale logistics. Capacity and large-size battery modules can be applied to light logistics vehicles.

Description

Technical field [0001] The present invention relates to the field of new energy vehicles, and more particularly to a battery module and a lightweight logistics vehicle. Background technique [0002] There are two main types of battery modules applicable to new energy vehicles, one is a cylindrical battery, which mainly uses serpentine flat tubes for heat dissipation, preferably maintaining battery operating temperatures, and extend battery life. However, the liquid cooling configuration of the cylindrical battery is high, and the battery is small, such as using light logistics vehicles, larger currents such as 90 ~ 100 kWh electrical cores are more, string and complicated, resulting in liquid cooling system prices Higher, not suitable for low cost, safe use of light logistics cars; [0003] Another large-scale battery mainly applied to large cars such as new energy commercial vehicles, which is mainly used to use heating membrane natural cooling or water-cooled plate cooling, wit...
