The Reasons for Common Charging Pile Jump Guns and Rectification Measures

With the rapid popularization of new energy vehicles, charging piles are used more and more frequently. Safe, convenient, efficient and stable ways of recharging energy for vehicles are crucial. When charging a new energy vehicle, under normal circumstances, the vehicle automatically stops charging when it is fully charged (or is considered to be charging). If the charging level is not met and the expected charging level is not reached, the charging ends abnormally and the expected effect is not achieved. This abnormal end is commonly known as “jump”. Gun” can also be understood as “stop charging”. This paper is based on the problem of abnormally high jumping rate of new energy vehicles when charging, combined with years of test experience, analyzes from many aspects, and proposes relevant countermeasures to reduce the jumping rate of charging piles, improve charging efficiency and reliablllty[1].
