In order to solve the defects of decreased vehicle comfort of pure electric passenger car when air conditioning system is turned on to cool the power battery, this paper, combining actual development projects, determined the typical travel chain of electric vehicle according to the sales target area of developed vehicle, and formulated the annual calendar driving conditions of electric vehicle according to the travel chain. The vehicle bench environment simulation test was carried out according to the annual calendar driving conditions, and the statistical analysis of the battery temperature distribution in three states of the vehicle in driving, charging and storage within one year was completed according to the test results. The battery cycle life evaluation was completed, and the influence of each operating condition of the vehicle on the battery life attenuation was decomposed, and the battery cooling system control strategy was optimized. The results indicate that, the proportion of cooling system engaged in the battery cooling process decreases greatly, air conditioning comfort improves obviously.
