Introduce the maintenance of lithium-ion batteries in electric vehicles.18650 battery rechargeable

release time:2023-09-12 Hits: Popular:AG11 battery

　　① Battery cannot be charged

　　There are several reasons for not being able to charge during charging, which can be divided into the following: the charger is connected in reverse or the charger is faulty; The protection board protection is not restored or the protection board is faulty; There is an external circuit between the battery pack and the consumer.

　　When dealing with the above adverse phenomena, check in order: whether the charger is connected in reverse, and whether the positive and negative pole plugs of the battery pack are connected in reverse; Restart the electrical appliance to remove the protection of the protection board, and measure whether the MOS tube of the protection board has a driving voltage; Check for loose and disconnected wiring connections.

　　② Short range

　　The battery pack quickly runs out of charge during use, and the reasons for this situation include: the lithium-ion battery is not fully charged; Large difference in voltage capacity of a single string; The battery pack is slightly short circuited or has a large self discharge, resulting in the battery pack being depleted as soon as it is fully charged.

　　To address the above issues, the battery pack can be recharged or defective battery cells can be replaced.

　　③ Battery board softening fault

　　The important manifestation is that the surface of the positive electrode plate gradually softens from a solid to a paste, and as the surface area decreases, it will lead to a decrease in battery capacity.

　　Repair method: After discharging 10.5v, discharge the bulb for 1-5 hours. Then there is the activator, which activates the repair. In this way, it is possible to repair, but in heavier cases, it can only be replaced with a new one.
