Fault and Maintenance Practice of New Energy Vehicle Power Battery
The research objective is to investigate the faults and maintenance practices of power batteries in new energy vehicles.During the research process,the case analysis method was used,com-bined with the battery failure performance of a new energy bus in Hubei.After diagnosis,the cause of the fault was reduced.In response to the 30A fuse melting fault caused by the loosening of the fixing nut of the lower terminal of the fuse,maintenance practices were carried out for the 30A fuse and the re-placement of the base.The research results show that one of the typical causes of accidents in new ener-gy batteries is power battery failure.In this regard,it is necessary to combine the specific types of pow-er batteries in new energy vehicles,classify the faults of power batteries in new energy vehicles,analyze the causes of the faults in depth,and finally propose maintenance measures for power batteries in order to eliminate the faults in a timely manner.The research conclusion points out that accurate diagnosis of power battery faults in new energy vehicles and effective implementation of battery maintenance prac-tices can ensure the safe operation of new energy vehicles and promote the healthy development of the new energy vehicle industry.
