Abstract

The invention discloses an electric automobile constant temperature battery compartment which can enable a power battery to locate in a suitable environment temperature range. The electric automobile constant temperature battery compartment is formed by sealing a car compartment floor (1), a front sealing plate (2), a rear sealing plate (3), an inner sealing plate (4), a lower sealing plate (5) and a battery compartment door (6), wherein heat insulation cotton (7) is disposed on the inner walls of the car compartment floor (1), the front sealing plate (2), the rear sealing plate (3), the inner sealing plate (4), the lower sealing plate (5) and the battery compartment door (6), which form the electric automobile constant temperature battery compartment, an air inlet and an air outlet which communicate the electric automobile constant temperature battery compartment with a car compartment are formed in the car compartment floor (1), a filtering screen (8) is arranged on the air inlet, and a thermoregulation fan (9) is installed on the air outlet. The electric automobile constant temperature battery compartment is applicable to electric automobiles, can prolong life of the power battery, and improves safety performance of the electric automobiles.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a constant temperature battery compartment of an electric vehicle. Background technique [0002] Traction battery is the main energy storage device of electric vehicles. The temperature of the battery not only has a certain impact on its discharge power and charging ability, but also greatly affects the life of the battery. Suitable operating temperature range is an important factor for optimal battery performance and extended service life. When the power battery is charged and discharged, it will generate electrochemical reaction heat and Joule heat generated by the internal resistance of the battery, which will increase the temperature of the battery itself. Taking 25 degrees as the base, the battery's operating temperature will increase by 10 degrees, and the battery's charge and discharge life will be reduced by 50. %, when the upper limit of the optimal operating temperature is e...
