Charging piles, the most important supporting facility for charging, are attracting people’s attention. In the charging process, the output voltage of a charging pile is up to several hundred volts. Any failure in the insulation or communication system of charging equipment may lead to charging accidents, even casualties.
Zhang Han et al. see the health evaluation, bad working condition evaluation and aging maintenance evaluation as the basic elements of the health state evaluation of a charging pile and predict the health state of a charging pile based on a Markov prediction model.
In the existing charging pile sharing platform, the user charging transaction data, personal privacy data and other related data are stored in a centralized database.
The standards [14, 15] for charging safety protection of batteries and charging equipment of electric vehicles have been formulated globally, including insulation , leakage , superheat , communication [17, 18, 19, 20, 21, 22, 23], and further research has been carried out on this basis.
The safety of outdoor charging piles, especially when the charging station is not under a roof, is affected by environmental factors. Their internal system may fail due to a thunderstorm, high temperatures, or a typhoon in summer.
In order to prevent accidents related to the charging safety of electric vehicles and ensure proper safety of passengers and people, the charging safety and charging safety protection methods of electric vehicles have become the research priorities for scholars.
