Abstract

The invention discloses a temperature adjusting system for electric vehicle batteries, comprising: a first reel and a second reel arranged on two sides of a battery box respectively, wherein the firstreel is rotationally arranged in an insulation barrel; a first motor and a second motor; a belt that includes two layers of base cloth sewn together and a heat-absorbing portion including a pluralityof heat storage tubes sewn between the two layers of base cloth, wherein the heat storage tubes are filled with a phase change material; an environmental temperature sensor; a battery temperature sensor; a heat storage tube sensor; a controller that captures an electric vehicle stop signal from an electronic control unit, wherein the heat-absorbing portion covers the lower portion of the batterybox for a period of time when the environmental temperature is lower than the lower limit of environmental temperature, and a hollowed-out portion is reeled to the second reel; wherein the controlleracquires an electric vehicle start signal from the electronic control unit, and the heat-absorbing portion covers the lower portion of the battery box when the battery temperature is lower than a lower limit of battery temperature. The temperature adjusting system for electric vehicle batteries provides automatic adjustment for battery temperature efficiently and helps extend the service life of each battery.

Description

technical field [0001] The invention relates to the field of new energy vehicles. More specifically, the present invention relates to a temperature regulation system for electric vehicle batteries. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles can also be called electric vehicles. The battery of an electric vehicle has certain requirements on the operating environment. One of the very important points is that the temperature of the battery should not be too low when the car is started, otherwise the battery will not work properly. Therefore, the temperature of the battery must be regulated and compensated. At the same time, the batt...
