Protector for improving performance of new energy vehicle battery

Abstract

The invention discloses a protector for improving the performance of a new energy vehicle battery, which includes a body and a battery pack. The body is provided therein with a heating chamber. The battery pack is fixedly arranged between the front and rear walls of the heating chamber. The left side of the heating chamber is in communication with a lifting cavity. The left side of the lifting cavity is in communication with an air intake cavity and a transmission cavity. The air intake cavity is located above the transmission cavity and is in communication with the outside. The protector canenable the battery pack of a new energy vehicle to still have high use efficiency in severe cold winter weather, and controls the frictional heat generation and air pressurized temperature rise through the mechanical transmission of a vehicle's power shaft during the start and travel of the new energy vehicle, enables the hot air to directly preheat the battery pack of the new energy vehicle, cangreatly improve the efficiency of the battery pack and increase the endurance mileage of the new energy vehicle in cold winter.

Description

Technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle battery performance improvement protector. Background technique [0002] At present, as the topic of environmental protection and less and less gasoline resources is getting more and more attention, new energy vehicles have been vigorously developed, and the purchase and use of new energy vehicles are actively promoted in various places. However, new energy vehicles are at the current level of development. There are still a large number of unsolved problems. For example, new energy vehicles use electric energy, and the electric energy devices installed on new energy vehicles are usually battery packs. Because they are batteries, they must not be used in severe cold winter weather. The less problem is that the efficiency of the battery is reduced, and the battery can keep the car’s cruising range greatly reduced due to the influence of low temperature. ...

Problems solved by technology

[0002] At present, with the topic of environmental protection and less and less gasoline resources being paid more and more attention, new energy vehicles have been vigorously developed, and various places actively advocate the purchase and use of new energy vehicles. However, with the current level of development of new energy vehicles, There are still a lot of problems that have not been completely resolved. For example, new energy vehicles use electric energy, and the electric energy devices installed on new energy vehicles are usually battery packs. Since they are batteries, they must be used in severe winter weather. The less problem is that the efficiency of the battery is reduced. Under the influence of low temperature, the battery can keep the mileage of the car greatly reduced. Generally, the solution for new energy vehicles on the market is to install a heating device, but this device still needs to use electricity. It will waste a part of the battery's storage power, and does not completely solve the battery life problem
