Abstract

Lithium-ion power battery pack provided with flame-retardant heat superconducting pipe, comprises a lithium battery box, a single battery, heat superconducting pipes, a heat removal fan and a refrigerant. The invention ensures constant, safety temperature in a lithium battery box while the lithium-ion power battery pack system is in normal operation. If any accidental collision or rollover of electric vehicle occurs in the running process, the vehicle lithium battery system may be damaged and burned because of strong external squeezing, however, if heat pipes placed inside the car are made of thin copper and aluminum, which would immediately crack under squeezing of the surrounding single battery, evaporation area of spilling refrigerant would suddenly increase with swift and violent endothermic phenomenon, which can extinguish or delay the fire by powerful cooling.

Description

technical field

[0001] The invention relates to a lithium-ion power battery pack for an electric vehicle, in particular to a lithium-ion power battery pack equipped with a flame-retardant thermal superconductor. When the lithium-ion power battery pack system is working normally, the temperature in the lithium battery box is guaranteed to be constant and safe. ; When the electric vehicle accidentally collides or rolls over during driving, it can effectively prevent the burning of the lithium-ion power battery pack due to external force extrusion. Background technique

[0002] The safety of the lithium-ion battery power system (hereinafter referred to as the lithium battery system) has become a national industry and the general concern for electric vehicles with lithium-ion power battery packs as the driving force, especially during the operation of pure electric vehicles (EV). People from all walks of life in automobile development pay close attention to the issue. Almost ev...
