Power battery temperature adjusting device for electric automobile

Abstract

The invention discloses a power battery temperature adjusting device for an electric automobile, and relates to the technical field of power battery temperature adjustment. The power battery temperature adjusting device comprises a control device and an execution device, the execution device comprises a base, a battery pack and a side plate, the battery pack is inserted in the base, a clamping hole matched with the battery pack is formed in the base, and the side plate is fixedly connected to one side of the base. According to the power battery temperature adjusting device for the electric automobile, through the arrangement of a temperature adjusting pipeline, the battery temperature adjusting device has the effects of being uniform in temperature adjustment and flexible and convenient in heat dissipation and heat preservation; through the cooperation of a compressor and a liquid path heater, in the using process, the refrigeration cooling and the heating heat preservation can be flexibly adjusted according to the temperature and speed signals provided by all the sensors, the temperature adjustment is uniform, and therefore the effects of being convenient to control and small in occupied space are achieved; and multiple layers of adjusting devices are matched with one another, so that the purpose of improving the battery temperature adjusting efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of power battery temperature regulation, in particular to a power battery temperature regulation device for electric vehicles. Background technique [0002] With the development of social economy, the demand for energy is further increased, and the voice of new energy technology is getting higher and higher. The development of electric vehicles is the general trend; as the core part of electric vehicles, the performance and service life of batteries directly determine the performance of electric vehicles. performance and cost. [0003] Due to the advantages of long life, low self-discharge rate, high specific power, high energy density and no pollution, lithium-ion power batteries have become the main power batteries used in electric vehicles; however, there is an optimal temperature range for lithium-ion battery discharge. When the battery temperature When it is too high or too low, exceeding its allowable...

AI Technical Summary

Problems solved by technology

However, the flexible adjustment of heating and heat preservation cannot be realized, the control is not sensitive, single-layer heat dissipation and heating, it is inconvenient to achieve flexible adjustment of battery temperature when the temperature is too high or too low, the adjustment effect is not ideal, and it has large inhomogeneity

[0005] Moreover, in winter, the low temperature will reduce the power performance of the battery. If the battery cannot be kept warm, the low temperature environment will have a great impact on the service life of the battery. The existing device has poor heat preservation effect, insensitive control, and takes up a lot of space.

[0006] Based on the above-mentioned technical problems in the cooling of electric vehicle power batteries, there is no relevant solution; therefore, it is urgent to find an effective solution to solve the above problems
