How to use the electric vehicle lithium power battery correctly

The correct use of the lithium power battery for electric vehicles is as follows:

1, the battery does not need to "activate"

Lithium batteries do not need to be charged for more than 12 hours in the first three times, and lithium batteries have no memory.

2, battery charging

Use the charger specified by the manufacturer to charge. When charging, please pay attention to whether the charger model matches the battery model.

3, avoid high temperature charging

Do not charge the lithium power battery in an environment where the temperature exceeds 40°. The high temperature will degrade the battery capacity.

4, timely charging

Lithium batteries should be used as much as possible to avoid charging, so that the battery can be recharged after each undervoltage, which can greatly improve battery life. 5, storage

When the battery is not used for a long time, disconnect the battery from the whole vehicle, and add some power to the battery at intervals to avoid self-discharge of the battery or the power consumption of the protection board.

Hello! The correct use of the lithium power battery for electric vehicles is as follows:

1, the battery does not need to "activate"

The lithium power battery used by the company does not need to be charged for more than 12 hours in the first three times.

2, battery charging

Use the charger specified by the manufacturer to charge. When charging, please pay attention to whether the charger model matches the battery model.

3, avoid high temperature charging

Do not charge the lithium power battery in an environment where the temperature exceeds 40°. The high temperature will degrade the battery capacity.

4, timely charging

Lithium batteries should be used as much as possible to avoid charging, so that the battery can be recharged after each undervoltage, which can greatly improve battery life.

5, storage

When the battery is not used for a long time, disconnect the battery from the whole vehicle, and add some power to the battery at intervals to avoid self-discharge of the battery or the power consumption of the protection board.

1. Do not replace the charger at random, do not remove the speed limit of the controller.

Chargers from various manufacturers generally have individual needs, so don't change the charger when you are not sure. If the mileage requirement is longer, you must equip multiple chargers for off-site charging. Charge the charger for the daytime supplement with an additional charger, and use the original charger at night. Removing the controller's speed limit, although it can improve the speed of some cars, but in addition to reducing the safety of the car, it will also reduce the battery life.

2, protect the charger

The general instructions for use have instructions for protecting the charger. Many users do not have the habit of reading the manual. They often think of looking for the manual after the problem. It is often too late, so it is very necessary to read the manual first. In order to reduce the cost, the current chargers basically do not have a high vibration-resistant design, so that the charger is generally not placed in the trunk and basket of the electric bicycle. In the case of special movements, the charger should also be packaged in foam to prevent bumps. After many chargers are vibrated, their internal potentiometers will drift, causing the entire parameters to drift, resulting in an abnormal state of charge. Another thing to note is that the charger should be kept ventilated during charging. Otherwise, it will not only affect the life of the charger, but also cause thermal drift and affect the state of charge. This will cause damage to the battery. Therefore, it is very important to protect the charger.

3, charging every day

Even if your continuation ability is not long, you can use it for 2 to 3 days, but it is recommended that you charge every day, so that the battery is in a shallow cycle and the battery life will be extended. Some users who used mobile phones early thought that the battery should be recharged after basic use. This view is wrong. The memory efficiency of lead-acid batteries is not so strong. Frequent discharge of electricity has a greater impact on the life of the battery. Most chargers may charge 97% to 99% of the battery after the indicator light is fully charged. Although only undercharged 1% to 3% of the power, the impact on the continuation ability is almost negligible, but it will also form undercharge accumulation, so after the battery is fully charged, it will continue to float as much as possible, to suppress the battery vulcanization. beneficial.

4, timely charging

The vulcanization process started after the battery was discharged, and at the beginning of 12 hours, significant vulcanization occurred. Timely charging can remove non-severe vulcanization. If not recharged in time, these vulcanized crystals will accumulate and gradually form coarse crystals. The general charger is powerless to these coarse crystals, which will gradually reduce the battery capacity and shorten the capacity. Battery life. Therefore, in addition to charging every day, it is also necessary to pay attention to the early charging after use, as much as possible to make the battery full.

5, regular deep discharge

Regular periodic discharge of the battery also facilitates "activation" of the battery, which can slightly increase the capacity of the battery. The general method is to periodically discharge the battery completely. The method of full discharge is to ride to the first undervoltage protection under normal load conditions on a flat road. Note that we place special emphasis on the first undervoltage protection. After the battery is under the first undervoltage protection, after a period of time, the voltage will rise and return to the non-undervoltage state. If the battery is used again, the battery will be seriously damaged. After the complete discharge is completed, the battery is fully charged. Will feel the battery capacity has improved.

6, develop some good habits of saving electricity

Use sliding as much as possible. When using the following slopes, use the early power-off slide to reduce the speed as much as possible. When you are about to encounter a traffic light, enter the taxi ahead of time to minimize the brakes. A friend told me that he would rather turn the bay once more and also reduce the brakes. This makes sense.

When starting up, it is best to add riding assistance, not only can increase the starting speed, but also reduce battery power loss and life damage.

7, pay attention to the charging environment

The best ambient temperature for charging is 25 °C. Most chargers now do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed for an ambient temperature of 25 ° C, so charging at 25 ° C is better. Otherwise, it will inevitably have problems of under-charging in winter and over-charging in summer. The ambient temperature is really less at 25 ° C, so there will be a problem of under-charging over-charging in summer. Fortunately, most families now have indoor temperature adjustment conditions, so when charging, it is best to arrange the battery and charger in a ventilated and temperature-controlled environment.

It is especially pointed out that when the battery enters the warm room in the outdoor low temperature in the north in winter, frost condensation will appear on the surface of the battery. In order to avoid leakage of the battery caused by frost condensation, it should be charged after the battery temperature rises to be close to the room temperature and dried.

8, make full use of maintenance conditions

Many electric bicycle dealers can provide battery overhaul and repair services, and should make full use of these services. Some brands of electric bicycles have been proposed to overhaul the battery. For example, regular maintenance of the battery can reduce damage to the battery. The repair of the state of charge of the battery can alleviate the "battery behind" failure, which is a breeze for dealers equipped with maintenance capabilities. For water loss, when the battery capacity is 70%, the hydration effect is better than the battery capacity of 40%. Even some brands of products have suggested that not going through the prescribed time is equivalent to giving up the warranty period of the battery. Consumers are subject to losses that should not occur. Therefore, consumers should make full use of the conditions of battery maintenance to increase the service life of the battery.
