AI Technical Summary

Problems solved by technology

If the temperature drops, the reaction rate of the electrodes will also drop. Assuming that the battery voltage remains constant, the discharge current will decrease, and the power output of the battery will also drop. The transmission temperature will drop, and the transmission will slow down. The charging and discharging performance of the battery will be affected, and it will fail to charge. Or when the usage time decreases sharply after being fully charged

Abstract

The invention provides a battery temperature control system for cars which is used in electric automobiles. Power batteries are sensitive to internal and external temperature, and have a large effect on normal operation of the batteries. Aiming at the problem, the battery temperature control system provided by the invention uses a liquid temperature control method to heat the power batteries and dissipate the heat of the power batteries used by the electric automobiles, so that the service performance of the power batteries is guaranteed.

Description

technical field [0001] The patent of the present invention relates to a vehicle battery temperature control system, in particular to a method of using liquid temperature control to heat and dissipate the vehicle battery. Background technique [0002] At present, electric vehicle-related technologies are developing at a rapid pace, and established automakers and emerging automakers continue to launch their own prototypes and production plans to compete for the attention of consumers. However, in the actual use of electric vehicles, there are still many challenges, one of which is the heat dissipation and heating of the power battery. [0003] As we all know, automotive power batteries, especially lithium-ion batteries, will generate heat when charging and discharging. This heat is harmful to the battery and is harmful to the life of the battery itself and the safety of vehicle users: It will lead to a series of side reactions, which will cause thermal damage to the battery. ...
