Abstract

The invention relates to a uniform-temperature heating power battery system and an automobile thereof. The system comprises a battery module, a battery module temperature measurement assembly, a heating unit and a heating control module, wherein the battery module is divided into a first battery module area with high natural cooling speed and a second battery module area with low natural cooling speed according to the measurement condition of the battery module temperature measurement assembly; the heating power is differentially designed according to the natural cooling characteristic and theactive heating characteristic of the battery module area; the active temperature uniformity function of the heating process and the passive temperature uniformity function of the charging process arecombined, and the series loop is used for overall control, so that the overall temperature uniformity of the heating process and the charging process is ensured, and the performance of the power battery is ensured.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a power battery system and an automobile with uniform temperature heating. Background technique [0002] With the continuous development of new energy vehicle technology and the continuous improvement of people's awareness of environmental protection, electric vehicles have become more and more popular. Electric vehicles use power batteries (that is, battery packs) to provide power sources to drive power motors to drive cars forward. As the main power source of new energy vehicles, power batteries have strict requirements on the working environment temperature. In use, the working environment temperature of the power battery is generally required to be -30.0°C-60.0°C. When the power battery works in a high temperature environment, the cycle life is reduced; when it works in a low temperature environment, the charge and discharge capacity is reduced. , which is determined by the chemi...
