The invention discloses a four-wheel direct-current charging pile charging module fault diagnosis method, which comprises the following steps: step 1, self-inspection of a use environment: self-inspection of the use environment of a four-wheel direct-current charging pile and conditions of a vehicle is carried out, and maintenance is directly carried out if problems exist; 2, appearance inspection: inspecting whether the appearance of the charging gun has problems, inspecting whether the appearance of a power line of the charging pile has problems, and inspecting whether a display screen has problems; 3, judging the software; 4, judging the state of the battery; according to the diagnosis method, the faults of the charging pile are classified into environment, appearance, software and charging module problems in sequence, after fault reason classification is completed, the faults exclusive to the charging module are specifically overhauled, and charging module protection is started while overhauled. Particularly, AC input overvoltage and undervoltage protection and over-temperature protection are carried out on the charging module, and the service life of the charging module is prolonged.

    本发明公开了一种四轮直流充电桩充电模块故障诊断方法,包括以下步骤:步骤一、使用环境自检:对四轮直流充电桩使用环境和车辆自身条件进行自检,如若存在问题直接进行检修;步骤二、检查外观:检查充电枪外观是否存在问题、检查充电桩电源线外观是否存在问题、检查显示屏是否存在问题;步骤三、判断软件;步骤四、判断电池状态;步骤五、模块检修,本发明该诊断方法依次将充电桩的故障分为环境、外观、软件和充电模块自身问题进行分类,故障原因分类完成后再对专属于充电模块的故障进行具体检修,且检修的同时启动充电模块保护,具体为对充电模块进行交流输入过压、欠压保护和过温保护,延长充电模块的使用寿命。
