Temperature automatic regulating system of lithium ion power battery in electric automobile

Abstract

The invention relates to a temperature automatic regulating system of a lithium ion power battery in an electric automobile. The temperature automatic regulating system comprises a water supply module, a temperature adjusting module, a lithium battery elevating module, a rotating module, a leakage-proof apparatus, an electric power storage module, and a control module and a pedestal; wherein, the water supply module, the temperature adjusting module, the leakage-proof apparatus, and the lithium battery elevating module are fixed on the pedestal and are arranged with an automobile rack together; the rotating module carries a pure electric automobile lithium battery and is arranged on the lithium battery elevating module, the water supply module and the temperature adjusting module are connected, the control module is respectively connected with the water supply module, the temperature adjusting module, the lithium battery elevating module, the rotating module and the leakage-proof apparatus for realizing the automatic control of the temperature. The temperature automatic regulating system can control the temperature equalization on each aspect of the automobile lithium battery, solves the problems in employment of two different devices for cooling and heating and leakage of a cooling liquid of a prior cooling and heating system, has the characteristics of safety, reliability, and convenient usage, and prolongs the lithium battery life.

Description

technical field [0001] The invention belongs to the technical field of lithium battery temperature control, in particular to an automatic temperature adjustment system for lithium ion power batteries in electric vehicles. Background technique [0002] With the country's further promotion of energy conservation and emission reduction, green and pollution-free pure electric vehicles are becoming more and more popular among consumers. The state's support for pure electric vehicles has also been further strengthened. Now many cities are developing pure electric buses, and many automobile manufacturers have also launched pure electric vehicles. Because lithium batteries have many advantages such as high energy density, no memory effect, low self-discharge rate, wide allowable operating range, and long service life, more and more pure electric vehicles now use lithium batteries as their power. However, due to the chemical reaction in the charging and discharging process of the el...
