What is the reason for the electric vehicle lithium-ion battery pack when charging? The lithium-ion battery charging method is substantially constant current charging, constant voltage charging, pulse charging, etc., using different charging methods at different stages, the electric vehicle lithium-ion battery pack has been with self-discharging characteristics, long-term and intermediate period If you are not charged, the self-discharge will make the battery power, causing the battery to be too low, charge the electricity. What is the reason for the electric vehicle lithium-ion battery pack when charging? The electric vehicle lithium-ion battery pack is charged when charging is charged, which can be divided into the following reasons: charger to reverse or charger failure; protective board protection does not recover or protect the panel failure; lithium-ion battery pack and electrical appliance external circuit.

For the above bad phenomena, check whether the charger is reversed, the lithium-ion battery pack charging positive and negative plug is reversed; re-enabled the protective plate protection, measure whether the protective plate MOS tube has a drive voltage; lookup wiring connection Loosen. Electric Vehicle Lithium Ion Battery Packet charges the important reason 1. Check if the loop connection is good, whether the charger is mixed in the electric vehicle lithium-ion battery pack, check whether the socket and charging line work properly to prevent the socket Failure, loose caused in the case of charge.

When charging, apply the charger that the electric car itself, prevents the string from using other cars, model charger, resulting in power-on invalidation. 2, the battery is seriously drum, causing electric cars to charge the drum battery first, check if it can be used. How to fix? Open the battery case, open the holes cover on the battery (the rubber cap on the heating hole is not lost), and it is observed whether there is liquid.

Use a syringe to absorb the distilled water 5 to 10 ml, add the liquid liquid hole, and add it again until the liquid is just over the electrode plate, and there is a water level instruction outside. 3, the lithium-ion battery pack is set for too long, resulting in too low the loss, the charger cannot charge the electric vehicle lithium-ion battery group long time does not have to receive a large damage, and common is that the battery enters the sleep state, which cannot be used normally. Or is more serious, it is the internal battery of the battery.

For this situation, the easiest way is to try to charge the low-type charger, and change the original charger. 4. Battery charging IC or BMS system causes problems due to the unence of the battery, resulting in problems with lithium-ion battery management system, resulting in management IC miscurs, causing the voltage or current.

How does the electric vehicle lithium-ion battery group charge better?. After the lithium-ion battery pack is discharged, the vulcanization process is started. At 12 hours, there is a significant vulcanization.

Timely charging, you can remove unscrupulous vulcanization, if it is not charged in time, these vulcanized crystals will accumulate to gradually form a coarse crystallization. ● Be sure to charge with the adarable lithium-ion battery charger, first insert the charger output plug insert the battery charging socket, and then insert the charger plug into the main hole, observe the indicator light to perform charging determination. If the charger is lost or damaged, please find the dealer to buy.

Can not be charged using a lead-acid charger or other form of charger. ● If the outgoing or long-term placement, the electric vehicle lithium-ion battery pack causes "running electricity", and the battery loss will seriously affect the battery life. It is recommended to charge once a month.

Summary: The above is the reason why the electric vehicle lithium-ion battery pack charge does not advance and the correct charging method of electric vehicle lithium-ion batteries. Through the sharing of this content, everyone's correct charging method and charging process of electric vehicle lithium-ion batteries have been detailed. Cognition, correctly grasp the charging time of lithium-ion battery pack, which will extend electric vehicle battery life.
