The development of new energy vehicles is a national strategy for China to transform from a big automobile country to a powerful country in automobiles. It is very important to ensure the charging safety of new energy vehicles.
In 2020, the National Big Data Alliance for New Energy Vehicles looks at the accident statistics monitored by the national supervision platform:
1) The vast majority of new energy vehicle charging accidents occur in the charging end stage and the resting stage after that;
2) The vast majority of accidents occur in the high SOC state of the power battery;
3) In the three stages of vehicle charging, standing and driving, the charging stage is the most suitable stage for the safety monitoring and analysis of battery indicators.
