Abstract

The invention provides a battery system and an electric automobile. The battery system comprises battery modules, wherein each of the battery modules comprises a plurality of battery module units; each of the battery module units comprises a plurality of batteries; a first heating pole and a second heating pole connected with the first heating pole are arranged on each of the batteries; each first heating pole is serially connected to a first branch; the second heating pole is serially connected to a second branch; the first branch is connected with a cathode of an external power supply; the second branch is connected with an anode of the external power supply; a temperature sensor is arranged in each of the battery module units and is used for detecting the temperature of the battery; an executing plate is used for collecting a temperature signal acquired by the temperature sensor. According to the battery system provided by the invention, the heating pole arranged on the battery can realize the heating of the battery. Such a heating manner increases the heating efficiency and guarantees the battery to be free from being overheated, and meanwhile, the increasing of the battery temperature can be completed within a short period of time, the battery temperature can reach the temperature for high-power charging and discharging, and the high power requirement of the whole vehicle is met.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a battery system and an electric automobile. Background technique [0002] With the ever-changing scientific and technological progress, people's pursuit of quality of life is getting higher and higher. Cars have become an indispensable means of transportation for people's daily travel. People are becoming more and more picky about the comfort, safety and environmental protection of cars. . [0003] New energy vehicles, especially electric vehicles, have led the future development direction of automobiles, and electric vehicles have gradually entered people's daily life. [0004] The battery commonly used in electric vehicles is a chemical power source that is charged and discharged through chemical reactions. Because the chemical reaction rate is significantly affected by temperature, generally when the temperature decreases, the chemical reaction rate decreases, so the...
