If the lithium battery cannot be charged after being stored for a long time, you can charge a single battery in the lithium battery pack or use a charger with lower voltage to charge the lithium battery. If that doesn't work, simply replace it with a new battery.
The activation method for lithium batteries that cannot be charged after being stored for a long time is to charge each individual battery in the lithium battery pack, and the charger used to charge them must be the original charger. If the voltage is the same, you cannot change the charger from one charger to another, otherwise it will be damaged. However, this method usually takes a long time. Another method is to use a charger with a lower voltage to charge the. lithium battery, that is to say for example It is said thatThe original charger current is 48 volts, so just use a 20 volt charger to charge.
However, the most direct method is to replace the lithium battery with a new one, or find a professional to repair it. If you don't know how to operate it, don't disassemble the lithium battery casually. After all, it is prone to explosion if not used properly.
Lithium Battery Maintenance
Lithium batteries are different from lead-acid batteries. They present the necessary conditions for rapid charging. They must therefore be charged. Different current chargers. There are also many time differences. Taking a 48V20AH battery as an example, if equipped with a 5A charger, it generally takes no more than 5 hours to fully charge. , it usually takes about 2 hours for a full charge. ByTherefore, lithium batteries should not be charged overnight or for a long period of time.
Many car owners actually cannot disconnect the power supply regularly. At present, they can choose switch sockets with timer and adjust the charging time according to the battery capacity to avoid overcharging and damaging the lithium battery.
Once an electric bike's lithium battery is too discharged, it can no longer be recharged. You can repair it yourself.
1. Once the electric bicycle lithium battery is over-discharged, it cannot be recharged because the battery capacity liquid is reduced and vulcanized. If it's not serious and only loses power occasionally, you can add a little diluted solution. sulfuric acid or sulfuric acid diluted 1:1.28.
2. Once the lithium batteryof an electric bicycle has been over-discharged for a long time, it cannot be recharged. If it loses power for a long time, the battery will be seriously vulcanized. the battery needs to be replaced.
Detailed information
How to properly maintain the battery:
1. From the time the battery leaves the factory to the time it is used. is installed in the car and then in your hands A rollover process During the rollover period, the battery will have insufficient capacity due to self-discharge. Therefore, the battery should be charged with a built-in charger until it is sufficient.
2. If you go on a business trip for a long time, the battery should be fully charged before storage, and the battery should be recharged once a month in the future to prevent it from being damaged by sulfate plate in raIgnoring long-term storage of battery power loss may result in reduced capacity or even disposal.
3. Points you should pay attention to when using electric vehicles in summer:
Avoid exposure to the hot and scorching sun, and charging in high temperature environments is strictly prohibited.
Avoid charging immediately after driving in high temperatures to prevent the charging time from being too long (normally around 8 hours).
If the power box becomes hot or the indicator light does not turn green when charging the battery, you should promptly go to the battery store or after-sales service point of our company for inspection and maintenance of the battery or charger. .
