Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle batteries, and in particular to a heating element for new energy vehicle batteries. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Currently, my country's new energy vehicle technology and ownership are among the world's leading positions, with pure electric vehicles accounting for the highest proportion of new energy vehicles. Although my country's pure electric vehicle technology is quite mature, some problems still cannot be effectively solved, such as the problem of battery use in low-temperature environments. Existing batteries will slow down the internal chemical reaction in low-temperature environments, which will lead to a decline in battery performance or failure, affecting the range and normal use of electric vehicles.

[0004] Therefore, there is an urgent need for a new energy vehicle battery heating element that can solve the problem of poor performance of existing new energy vehicle batteries in low-temperature environments. Utility Model Content
