After using the electric vehicle charger for a long time, it is inevitable that some problems of this kind will occur. These are inevitable. We cannot guarantee the service life of the charger, but we can try to extend its service life. When there are some minor problems with the electric vehicle charger, we can first conduct our own investigation and do some simple processing on the vehicle, which can also reduce some unnecessary troubles. Yidili Power Technology is here to share with you some daily troubleshooting methods for electric vehicle chargers. , squeaking, heating, or insufficient charging during charging. Turn on the power and measure the voltage of the large capacitor. As long as it is lower than the capacitor voltage, it is usually because the capacitor has failed and can be replaced.
. The power supply does not turn on. Plug in the power supply, but the large capacitor has voltage. Unplug the power supply and measure the voltage at the large capacitor terminal again, but the voltage does not drop. After discharging the capacitor, replace the starting resistor. The starting resistor is in the power input part, with resistance value and power.
Severe fever is usually caused by a problem with the fan. Just check and replace it with a new one.
When power is on to burn out the fuse, first check whether the power tube has been broken down. If not, replace all rectifier diodes with new ones, and then test the machine to see.
If the light does not turn on when charging, first use a tester to check various data. Generally, the voltage of a newly charged battery is not higher than that of a battery charged for about half a year. It is normal that the voltage of a battery charged for about half a year is not higher. If the voltage is higher than this, the light may not turn on.
. Low output and hot. If the output voltage is lower than much and the power tube and transformer are hot, it is usually because there is a problem with the transformer. You can go to the store for a detailed check.
In addition, during normal use, electric vehicle chargers should be kept away from harmful gases, flammable materials, explosives, corrosive chemicals, and strong mechanical vibrations, impacts, and magnetic fields. The packaging box needs to be placed at least high from the floor and away from walls, heat sources and vents. The charger can be stored for two years under safe storage conditions. If it exceeds two years, it must be retested. If it is not used for a long time, the charger should be powered on every three months, and the power-on time should be no less than half an hour. If you use it a lot in daily life, you should pay attention to charging frequently, not overcharging or undercharging.
Of course, choosing a good quality charger is the best way to go. Yidili charger adopts intelligent charging, which is extremely safe. It can automatically recognize the battery voltage and promptly judge whether to insert or remove the battery. After disconnecting the battery, the charger can automatically cut off the power and adopt four-stage intelligent charging technology when charging. In addition to extending the battery life, it has high charging efficiency and can charge quickly. It is a trustworthy brand.
