Compared with ordinary batteries, new energy batteries are more suitable for vehicles under the current technical conditions, so they have a wide range of applications. The performance of new energy batteries in daily life is often unsatisfactory. However, after they are applied to new energy vehicles, the disadvantages of new energy batteries are gradually eliminated due to scientific charge and discharge management, and the advantages are obvious. This paper starts from the development history of new energy,the battery technology of new energy electric vehicles is deeply analyzed, and the dynamic analysis of battery charge and discharge in new energy electric vehicles is carried out.
