Abstract

The invention discloses an alpine region new energy automobile lithium battery heat management system. The alpine region new energy automobile lithium battery heat management system comprises a lithium battery pack, a heating system, a control system and a working solution. Aluminum alloy serves as a heat-conducting sheet, the working solution serves as a heat-conducting medium, and the temperature of the working liquid is transmitted to the heat-conducting sheet and then is transmitted to the core of the lithium battery through the heat-conducting sheet, so that management on the temperatureof the lithium battery is realized. By the set of system, the lithium battery is stilled maintained to be at the optimal working temperature. In addition, when the control system detects that the rotating speed of a motor is zero and the temperature of the lithium battery is too low, ECU controls the heating system to work intermittently, so that an automobile can start rapidly. The alpine regionnew energy automobile lithium battery heat management system is simple in structure, safe, reliable, low in cost and high in practicability, and can accelerate the use of the electric automobile in the alpine region.

Description

technical field [0001] The invention relates to a thermal management system for a battery, in particular to a thermal management system for a lithium battery of a new energy vehicle in an alpine region. Background technique [0002] As the main energy storage device of electric vehicles, lithium battery pack is a key component of electric vehicles, and its performance directly affects the performance of electric vehicles. In the low temperature environment, the battery life of electric vehicles is shortened mainly because the extremely low temperature will affect the activity of lithium compounds. However, under low temperature conditions, the activity of these compounds is weakened, and the charging and discharging efficiency is reduced, which reduces the battery life of electric vehicle lithium batteries, causing difficulty in starting the vehicle, lack of power, and even failure to drive normally. It is an efficient way to control the temperature of the battery by contro...
