The traditional low-temperature charging and discharging technology of new energy vehicles has low power saturation index and can not meet the endurance requirements of new energy vehicles.Therefore,a new low-temperature charging and discharging technology of new energy vehicles is designed based on electromagnetic induction.The low-temperature charge discharge coupling transformer of new energy vehicle is designed,the low-temperature charge discharge compensation is calculated based on electromagnetic induction,the low-temperature charge discharge frequency of new energy vehicle is tracked,and the low-temperature and efficient charge discharge of new energy vehicle is realized.The experimental results show that after applying the low-temperature charging and discharging technology of new energy vehicles designed in this paper,the vehicle power saturation index is higher,which meets the endurance requirements of new energy vehicles,and can be used as a reference for the subsequent research and development of new energy vehicles.
