What should I do in the electric car battery?

The electric vehicle battery often occurs in the use of the charging drum, resulting in two factors in the deformation of the battery drum, one is the quality problem of the battery itself, such as the internal electrolytic solution of the battery; another factor is inappropriate use of. There are several aspects of the bulk bags caused by the battery: 1. It is important to change the properties of the active material in the long-term overcharge battery.

At the same time, the charging process is also the process of electrolytic water, especially in the late stage of charging, the active substance has been fully transformed, continue Charging will speed up the decomposition of water in the battery, resulting in reduced electrolyte, and battery often charge will lead to the emergence of drum bag. When the battery is charged, after the charger turns, you will cut off the power at 2 hours, otherwise it will cause overcharge. 2, often large current charging electric car battery charging current is usually 0.

12 ~ 0.15c2, such as 20ah battery, maximum charging current is 3A. The large current is charged.

One means that the charging current of the charger is too large, the other is to use the fast charging station to quickly charge the battery, the charging current of the fast charging station generally reaches 10A, far exceeds the specified charging current. Regular large current charging will cause the battery to be lost, the battery will drum. 3, using inferior chargers, the electric motor vehicle market is full of inferior chargers, some miscellaneous electric vehicles are mostly equipped with this charger for reducing costs, many consumers do not pay attention to the quality of chargers, and they are cheap.

Buying this charger, cost is generally more than a dozen yuan. The electronic components of this charger are basically adopted by inferior materials. It is easy to damage.

The frequent problems is that the battery is not turned back, and the charging current cannot be adjusted according to the battery voltage, causing the battery to overcharge, after multiple times Battery will drum. 4, the charger does not match the battery used by the different electric vehicles, one is that the battery is different, and the second is that the voltage of the battery is different, and there are 48V, 60V, 72V, but some electric car users are using the process. In the middle, it will be used frequently, take 60V charger charger for the battery, take 20ah charger charge 12AH battery, charging voltage and current do not match, of course, will cause the battery to be filled with drums, and even new batteries A few days of drum.

5, the charging temperature is too high, and there are two aspects: one is the impact of the ambient temperature, especially in the summer, the temperature is high in summer, the internal temperature of the battery is high, and the charge is charged at high temperature, and the time is long. The battery will drum. Therefore, after using the electric car in the summer, one should not charge immediately, and the second is to charge the charging of the cool and ventilated place.

Second, it is necessary to pay attention to the battery when the battery is installed. When it is supplied, it can be dissipated. Some users are installed when the battery is installed, so that when the battery is charged, the heat is disseminated.

When charging, the battery temperature is too high, speeding up, time long, battery will have a phenomenon of drums, all manufacturers' chargers generally have personalized demand, do not replace charger at will not. If the mileage requirement is relatively long, you must use multiple chargers to charge offically, the charger charged during the day, using additional chargers, and the original charger is used in the evening. Do not remove the speed limit of the controller remove the speed limit of the controller, although the speed of some cars can be improved, in addition to the safety of the car, it will also reduce the service life of the battery.

Protecting the Charger General User Manual has a description of the protection charger. Many users don't look at the habits of the manual. In addition to the problem, I want to find the instructions in the future, often too late, so I will first look at the instructions is very necessary.

In order to reduce costs, the current charger is basically not designed with high vibration, so that the charger should not be placed in the trunk and the basket of electric bicycles. In special cases, you must move, but also pack the charger with foam plastic, prevent the bump of vibration. Many chargers have passed through vibrations, and their internal potentiometers will drift, so that the entire parameter is drifted, resulting in abnormal charging state.

In addition, it is to pay attention to the charging of the ventilation of the charger, otherwise it will not only affect the life of the charger, but also the thermal drift can affect the charging state. This will form damage to the battery. Therefore, it is also very important to protect the charger.

Every day, even if your renewal capacity is not required, it can be used for 2 to 3 days, but it is recommended that you charge each day, so that the battery is in a shallow cycle, the battery life will be extended. Some early use of mobile phone users think that the battery is basically basically used in the future, this view is wrong, the lead-acid battery memory benefits are not so strong. Always put the life of the battery is relatively large.

Most chargers indicate that the light-made light indicates that the battery can be charged into the electricity of 97% to 99%. Although only 1% to 3% of the electricity, the impact of the continuation capacity is almost neglected, but it will also form an under charge accumulation, so the battery is filled with the electric shifting, and the floating charge will be continued as much as possible, and the vulcanization of the battery is also beneficial. .
