Analysis of the reasons why the three-wheel electric vehicle is not charged:
1. Battery life expires
Even the best battery products have their own life cycle. If the electric vehicle has been unable to charge, we must first consider the battery life problem, the general battery life cycle in 2-3 years, the main factor determining the life is mainly related to the user's use habits.
Second, the fuse is disconnected
If the battery's internal fuse breaks, the battery is dead. What to do at this time is to go to a special electric vehicle repair shop or a car store to replace the fuse, do not change yourself.
Third, poor contact
When the contact between the safety tube and the safety seat is poor, there will also be a situation where the electric vehicle battery is not charged or is dissatisfied, at this time, the user needs to go to a professional maintenance shop for maintenance, so as to solve the problem of dissatisfaction or failure to charge.
Fourth, poor contact with the power supply
Poor power contact is a problem that many users will encounter, 30% of the failure of the electric car battery is from the battery and the power supply caused by poor contact with the electric car is not charged or charged, at this time you need to unplug the charger, plug it back in, the state is in contact with no harm, to see whether the charge is dissatisfied or not charged.
Five, the line problem
If the charging line is disconnected or removed poorly, it will also lead to no charging response, and it is necessary to overhaul the vehicle line.
6. The charger is damaged
The charger of the user of the Xiudou electric vehicle has failed during use, resulting in battery parameter drift, or has lost the function of charging, although the indicator light will be on, but it has actually stopped working. This requires a replacement charger.
Seven, the battery short-circuit problem
Due to the high density of the battery, when riding the road bumps, the battery is collided and the battery is broken, this situation needs to go to a professional maintenance network, if it is determined that the charge is not charged for this reason, the battery needs to be replaced.
1, for the polarization voltage is not high battery is more likely to appear, the ordinary three-stage charger, in the first and second stages of charging, due to the single cell charging voltage is too high, more than the single cell 2.45V, some batteries will appear charging current can not fall to the charger full of the current judgment, thus can not enter the full state. As the battery continues to charge, the gas bubble and heat, the temperature rises, and the polarization voltage becomes low, and the current can not be reduced.
2, charger reasons: some chargers in the first and second stage of the voltage limit value is much higher than the single cell of 2.45V, making it more difficult to enter the full state.
solution
1, change a better charger.
2, Adjust the voltage, the single cell charging limit voltage down to 2.33V.
Note: The bubbling phenomenon of the battery car, long-term gas bubbling scouring the plate, not only makes the active material fall off into a self-discharge (the partition process is not good water bottle, other batteries do not exist this problem), but also the positive plate gradually decayed (from the metal frame to non-metal, from the entire plate into loose mud), and gradually entered the complete scrap stage in advance.
First of all, do you consider whether the fuse is damaged in this case to replace? Try to replace this situation, and repair it to solve the problem of poor contact damage
After long-term use, the battery life is damaged. Loss of power is inevitable during charging
