The battery is completely broken.
In a certain way, the electric vehicle battery has a use time, that is, it has a certain life. At present, most battery cars use lead-acid batteries, charging and discharging cycle is about 300 times, normal use for a year and a half, the capacity has fallen to within 80% of the rated capacity, the capacity has become smaller, of course, it can not be charged into the electricity, that is, the surface is charged, full, the actual inside there is not much electricity, simply run.
When the battery is put away for a long time, it needs to be charged every once in a while to maintain a certain amount of electricity to make it active, otherwise it will also be damaged by aging. When the battery is broken, it is generally impossible to repair it and can only be replaced with a new one.
2. The charger is damaged
Electric car chargers, there are indicators. The charging process will show a red light, and the discharge process will naturally show a green light. However, because the charger is used for too long or other problems cause the charger to be damaged, it is not charged when charging, so it will also appear that the charge is full and the ride is out of power.
If the internal line of the charger is in poor contact, after connecting the circuit, it will not work normally, so the green indicator of the charger will also light up, making people mistakenly think that it is full of electricity, but it is not charged into the electricity.
3, wiring problems
In other words, when charging an electric vehicle, if there is a problem with the wire line, it will give people an illusion that it is not charged, and the green indicator light of the charger has been lit up to show that it is full, so there will be a display when riding an electric vehicle that the battery is out of power.
There is also another possibility that the wire connected to the charger has no electricity at all, so that the green indicator light will light up after the charger is connected to the socket, and it will give a person the illusion that it has been full of electricity.

The line is broken

Check whether the connection of the charging circuit is reliable, check whether the connection is in good contact with the plug, and carefully check whether the plug of the socket box is. Start a fire Arc burning phenomenon, whether there is line damage, broken line, etc. Check whether the charger is damaged and whether the charging parameters meet the requirements.

The fuse is in poor contact
< br >
When the contact between the safety tube and the safety seat is poor, the battery will not be charged or charged, as long as the position of the two is adjusted to make it in good contact, the problem will be solved.

The internal plug-in is not in good contact
< br >
If the plug-in in the battery is in poor contact or the lead is broken, it will not be charged. You can plug it back in or replace the cable.
