Embodiment Construction

[0044] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0045] A specific embodiment of the power module of the present invention, such as Figure 1 to Figure 8As shown, a power module includes an assembly 19 , an insulating plate 20 , an upper fixing component 14 and a lower fixing component 15 . The assembly 19 is formed by stacking battery components. The battery component is composed of a battery 1, a frame 2 and an aluminum plate 3. The battery 1 is fixed in the frame 2 by pasting. The frame 2 is a plastic part, and the aluminum plate 3 is pre-embedded by injection molding. The form is fixed in the frame 2 formed by plastic parts. The aluminum plate 3 is a U-shaped structure. The heat generated during the discharge process is conducted through the U-shaped bottom wall of the aluminum plate 3, and then diffused through the U-shaped folded edge, which facilitates the heat conduction and heat dissipation o...

Abstract

The invention relates to a power supply module and a vehicle. The power supply module comprises a battery pack and a box body; the box body has a cavity for fixing the battery pack; the battery pack comprises two or more overlaid framework units; a fixed plate for enabling the framework units to be in tight contact is arranged on the tab side of the battery pack; the fixed plate and the battery pack form an assembly part; and the assembly part is fixed in the box cavity which is matched therewith. The fixing structure of the power supply module can directly realize positioning and fixing through the fixed plate of the battery pack, and next, the well-fixed assembly part is put into a sealed box, so that the firm fixation of the power supply module is ensured while relatively high energy density and relatively high energy conversion ratio are achieved.

Description

technical field [0001] The invention relates to the field of soft pack lithium batteries, in particular to a power module and a vehicle. Background technique [0002] In recent years, the new energy industry has developed rapidly, and lithium-ion batteries are widely used because of their advantages such as light weight, large energy storage, no pollution, long life and small self-discharge coefficient. In the field of electric vehicles, in order to meet the long-term driving of electric vehicles, it is necessary to connect several lithium-ion batteries in series or in parallel to form a module, and then form the entire battery system through the series and parallel connection of modules to meet the demand. [0003] For soft-pack lithium batteries, when high-energy and high-voltage batteries are needed, it is necessary to connect the tabs of several soft-pack lithium batteries in series or in parallel to form a soft-pack lithium battery module, but each module formed Due to...
