The reason why the lithium battery cannot be charged and the green light is always on is that the charger converter or fuse is defective, the battery is defective and the wire connection is disconnected or virtually connected. .
1. The charger converter or fuse is defective.
If the electric vehicle cannot be charged and the green light is still on, you should first determine whether there is anything abnormal with the charger. It is very likely that the converter or fuse is defective. the electric vehicle is defective. The converter or fuse needs to be replaced. If the problem cannot be resolved, the only option is to replace it with a suitable charger.
2. The battery is defective.
If a small battery in the battery pack is shorted, the green light will stay on during charging.arge. You can find a maintenance technician to check whether there is any abnormality in each battery. After finding the fault, try to see if it can be repaired. If it cannot be solved, you can only replace the battery with a new one.
3. The connection cable is disconnected or poorly connected.
In addition to the two main reasons above, there may also be connection line disconnection or virtual connection. Typically, the interface is disconnected or has a virtual connection. You can try unplugging and plugging in the charger several times and charging it several times. If the green light still stays on, you can try replacing the connection cable.
Also, it should be noted that you usually cannot detect specific problems yourself. You must therefore be attentive when anomalies or malfunctionss occur in electric vehicles.
What is a lithium battery?
Lithium battery is a type of battery that uses lithium metal or alloy lithium as the negative electrode material and uses a non-aqueous electrolyte solution. The first lithium battery came from the great inventor Edison, using the following reaction: Li+MnO2=LiMnO2 This reaction is a redox reaction.
As the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. Today, lithium batteries have become common.
What should I do if the lithium battery electric vehicle I just purchased does not respond to charging?
If the light turns green as soon as it is charged and cannotnot be charged, it means there is a problem with the batteryThe battery capacityis. seriously lost and must be checked and replaced. The second reason is the charging failure caused by the charger problem, and the charger needs to be replaced.
Precautions for charging lithium batteries
Do not overcharge or discharge. Since lithium batteries are non-memory batteries, it is recommended to charge or recharge the battery regularly after each or every day of driving, which will significantly extend the life of the battery. Overdischarge or self-discharge reaction at low voltage will cause the lithium-ion active materials to decompose and destroy, and any form of overcharging of lithium-ion batteries will seriously damage the battery performance or even explode.
Recharge on time. After being discharged, beat themLithium ries will enter the sulfidation process if charged in time, less serious sulfidation can be eliminated.
Without electricity, electric vehicles will not move. On the surface it appears to be fully charged, but in reality it is not. Also, after unplugging the charging plug after charging, the electric vehicle plug was not plugged in.
1. The battery has zero voltage or there is a battery with no voltage in the combination battery. The battery without voltage is either itself an inferior product and did not achieve the corresponding rated capacity and voltage value when it left the factory, or it has reached the end of its service life. Due to long-term use, the capacity is exhausted and. the voltage drops to zero.
Considering that after long-term storage of lithium batteries, for example more than a year, the energy may be exhausted in the form of autodischarge and the voltage will be zero. The current protection of the lithium battery. The system is designed to require the battery to have zero voltage. It can also be charged.
Therefore, there are two differences between voltage-free batteries. One is that they can be charged and continue to be used, and the other is completely worthless; in other words, the loss of capacity of the first is reversible; and the other is completely useless. It's irreversible. If a zero-voltage battery that cannot be charged is unfortunately designed into a lithium battery, the zero-voltage signal may be transmitted to the battery through the protection chip, thereby turning off the MOSFET and making the battery unable to charge.
2. The battery is incorrectly connected. This situation is less likely to occur because rechargeable batteries or battery packs generally need to be fully inspected before being released.itter the factory. This happens to batteries from common manufacturers, unless a certain batch of batteries is not fully inspected before leaving the factory and it is the bad battery. The pack is connected. He's on the unchecked list.
Of course, it's a different matter for products made by non-regular manufacturers or assembled by individuals. Connection errors cannot be completely eliminated. Relatively speaking, the complete inspection rate of nickel-metal hydride batteries is lower, and the probability of such errors may be greater.
3. The internal electronic components and protection circuits are abnormal. This situation usually occurs after prolonged battery use. Aging and falling of electronic components will cause the battery to charge abnormally. Especially when the electronic components integrated into the protection circuitection present the above situation, it will directly affect the protection. operation of the circuit. As a result, the charging process cannot be guided correctly.
