Lithium-ion battery electric vehicle charger measure standard, lithium electric motor vehicle charging precautions. At present, there is a measure of the standard for lithium-ion battery electric vehicle charger. Therefore, we must use a dedicated electric vehicle charger, but the charger is mixed, and the inferior charger is quite large, and it can use a few times.
The charge is reduced, and the life is shortened, so there should be corresponding requirements for the charger. Here are you to introduce the lithium-ion battery electric vehicle charger measurement standard and lithium electric motor charging precautions. Lithium Ion Battery Electric Vehicle Charger Measurement Standard (1) Charge starts with a large current, fast charging function in a short period of time, and rush into the total capacity of more than 80% of the total capacity within 15 minutes.
According to the supporting battery category, the current is changed according to different charging phases, adapt to the characteristics of different battery poles, the charger should have a large positive pulse to impact and break the vulcanized crystals of the polar active substance, so that the active substance maintains a good charge. Discharge activity. The result is not only the capacity of the L-C battery remains stable, and the life will be clearly extended.
(2) Charge to the final stage automatically transfer the trickle for fine charge, is the sufficient reaction of each battery polar plate active material, and make each battery to charge each other as much as possible. (3) After reaching the charging termination voltage, the charger voltage must be accurately fixed on the battery's charging termination voltage line, absolutely not exceeding. (4) The charger should have temperature compensation to prevent damage due to the high temperature is too high.
When the battery is reached, the output circuit is automatically turned off when the battery is allowed, and the temperature is reduced and charging. (5) About the charger of the metal hydride-nickel battery, should also have functions that can properly improve the charging voltage, which reduces the latter capacity in use. In order to make the battery have a good capacity state, it is possible to improve the charging voltage to increase the charging termination voltage from the original 1.
5V to 1.6-1.7V.
If the user is in the car, if it is equipped with a nickel-hydrogen battery, it should ask if the charger can be improved. Charging voltage. Lithium Electric Vehicle Charging Precautions 1.
If the charger is lost or damaged, please use the dealer to purchase, and can not be charged using a lead-acid charger or other form of charger. 2, long-term use of electric vehicles should be disconnected from the battery and the entire vehicle, and the battery is added to the battery in a period of time to prevent battery self-discharge. Lithium-ion batteries do not allow empty storage, if you don't apply a lithium-ion battery for a short time, please store the battery to more than 50%, and the battery must be replenished every 30 days.
3, when charging the battery, if the charger plug is constantly fever and the heat is long, it is necessary to immediately check if the plug is shorted or the contact is poor, and the charger should be pulled out to check whether the plug is on the presence of oxides and immediately remove it immediately. Lose. 4.
Recommendation with charging. After the lithium-ion battery pack is discharged, the vulcanization process is started, and there is a significant vulcanization at 12 hours. Timely charging can remove unscrupulous vulcanization, if not recharge these vulcanized crystals, gradually form a coarse crystallization.
The above is a lithium ion battery electric vehicle charger measurement standard and lithium electric motor charging precautions. It is expected that the lithium-ion battery electric vehicle will be promoted in the next three to five years, but the high price of electric power from the lithium-ion battery also makes consumers. I believe that with the maturity of lithium-ion battery production technology in the next few years, it will enter people's families with a reasonable price.
