Abstract: As a common fault in the maintenance work of electric vehicle, whether the alternating current slow charging fault of electric vehicle can be effectively diagnosed and quickly repaired is crucial for improving the user experience and ensuring the charging safety of electric vehicle. Focusing on the key link of the charge control guide circuit, this paper deeply analyzes the working principle of the slow charging system of electric vehicle, closely combines the actual maintenance experience, summarizes the common causes of the alternating current slow charging failure of electric vehicle, and designs a set of fault diagnosis process and maintenance steps, covering the whole process from fault location to fault elimination. It provides reference and reference for technical personnel to solve electric vehicle alternating current slow charging system fault quickly and accurately.
