Abstract: Aiming at the problems in which the normal work of new energy vehicles at low temperature is affected, the dynamic characteristics of the battery of new energy vehicles is decreased, and the charging and discharging efficiency decreased, for the battery thermal management as a starting point, this paper designs a set of new auxiliary heating system, and through the real car bench and road tests verify the effectiveness of the proposed set of design. The test results showed that the average mileage of the vehicle has been effectively improved to 54.6% after the power battery is heated by the heating system, improved the new energy vehicles the problems of low efficiency in low temperature environment. It will provide an effective engineering reference for the efficient utilization of dynamic characteristics of new energy vehicle batteries and the development of technologies.
