Multi-effect power module for electric vehicle

Abstract

The invention relates to a multi-effect power module for an electric vehicle, comprising a power module, a heat-insulation flame-retardant module and a shell anti-collision module, wherein the power module as a power source provides stable voltage and power for the electric vehicle; the heat-insulation flame-retardant module consists of a functional foaming body with an integral sealing profiling structure, and the functional foaming body is made of foam material and has the effects of water and moisture prevention, heat preservation and insulation, flame retardance, fire resistance, shock and collision avoidance and electromagnetic radiation prevention; and the shell anti-collision module consists of metal or nonmetal materials which have mechanical strength and heat conductivity. The invention ensures that the components have optimal environment-friendly ecological conditions by using environment-friendly nontoxic materials and components and partial materials can be recycled; and besides, functional parts, such as a heat conducting system and the like, can be conveniently added on the structure because the functional foaming body has the characteristic of convenient secondary processing.

Description

technical field [0001] The invention relates to a power module, in particular to a multi-effect power module for an electric vehicle integrating fire protection, heat preservation and other functions. Background technique [0002] High-energy batteries are widely used in industrial fields, especially in the field of electric vehicles. The current electric vehicles have excellent efficiency, economy and environmental protection because they use high-energy batteries as energy storage and supply systems to replace or partially replace traditional car engines that use fossil fuels. High-energy batteries include magnesium dry batteries, metal-air batteries, lithium-nonaqueous electrolyte solution batteries, sodium-sulfur batteries, and lithium high-temperature batteries, as well as zinc-halogen batteries, sodium-water batteries, and lithium-water batteries under development. [0003] Such as figure 1 As shown, taking a commonly used lithium-nonaqueous electrolyte solution batt...

[0004] Invention: Power-off safety structure for overcharging of soft-shell lithium batteries (application number: 200710090895.2, application date: 2007-04-11), the disclosed method is to connect a safety circuit to the lithium battery, but this method can only prevent overcharging The explosion caused by the electrolyte degassing has no effect on the explosion caused by other reasons

Invention: Safe Lithium Battery Shell (Application No.: 200810020116.6, Application Date: 2008-03-25), which discloses a sealed lithium battery shell. By setting a safety explosion-proof mechanism on the side of the shell, the lithium battery is drained due to electrolyte The pressure generated by the gas can achieve the purpose of explosion-proof; because the safety explosion-proof mechanism is to set a plurality of explosion-proof holes on the side of the lithium battery shell, the explosion-proof holes are covered with an explosion-proof film to isolate the lithium battery from the external environment, which will inevitably reduce the shell itself. Strength, it is difficult to achieve the effect of shock absorption and anti-collision
