Correct charging and maintenance method of lithium battery in electric vehicle

Correct charging and maintenance method of lithium battery in electric vehicle:

1. Charge according to standard time and procedure, even the first three times.

2. When the lithium battery is too low in the driving process of electric vehicles, it should be charged as soon as possible and timely.

3, lithium battery electric vehicle activation does not need special method, lithium in the electric vehicle driving

The battery will activate naturally.

4, the car is equipped with a special charger for charging, the charger output plug corresponding to plug into the battery charging socket and then plug the charger plug into the city power jack, observe the indicator light for charging judgment (generally red light indicates charging, green light indicates basic sufficient power, the more discharge, the longer the charging time).

5. After the charger indicator light turns green, charge it for 1-2 hours, and then stop charging.

The lithium electric car USES the environmental protection light lithium ion battery, has the capacity big, the life is long, does not need the maintenance, the weight is light, does not have the pollution and so on prominent characteristic. At the same time, the service life of lithium battery is closely related to your correct use. This paper discusses the use and maintenance of the battery according to the characteristics of lithium battery for reference.

You buy a new car, in order to transport safety, the battery factory is in semi-electric state, you must ride before the battery is fully charged before use, the first charge time is not less than 10 hours. (note: use the car's supporting special charger for charging. When the charging indicator is green, please continue charging.)

Don't run out of battery every time you ride. If you run out of battery, it will greatly reduce the battery life. Remember!! Because lithium batteries have no memory effect, they can be recharged at any time. So you should develop the good habit of timely charging after use, so that the battery life can be extended 3-5 times.

Battery life is affected by the environment at the same time, the use of the product temperature within the range - 20 ℃ and 60 ℃, the temperature is too high will affect its service life, low will reduce the effective capacity of 20% 30% (influence line continuation mileage).

Do not let the battery get wet or soak in water.

If you do not use the battery for a long time, please charge it once within 90 days. It is strictly prohibited to store it at a loss of power. Once the battery voltage reaches the discharge state, it will cause great damage to the battery and cannot be recovered.

Before using the battery, be sure to read the "notes for use of WST lithium ion battery pack" on the battery shell.

And now the lithium battery price is low price is not a myth, shun yi lithium electric vehicle cost performance is very good. The state four ministries and commissions issued a regulation electric vehicle market, will make lithium electric vehicle rapid development, so with the battery will be very convenient.

1. Do not change the charger casually and do not remove the speed limit of the controller

The charger of each manufacturer has personalized demand commonly, do not change charger at will when uncertain. If the mileage requirement is long, multiple chargers must be equipped for remote charging. The charger that is fully charged during the day should be replaced with a supplementary charger, and the original charger should be used at night. Removing the speed limit of the controller can improve the speed of some cars, but it will not only reduce the safety of the car, but also reduce the service life of the battery.

2. Protect the charger

General operating instructions have instructions on how to protect the charger. Many users do not read the manual habit, often in addition to the problem after thinking of looking for the manual to see, often too late, so it is very necessary to read the manual first. In order to reduce costs, the current charger is basically not done high vibration resistance design, so that the charger generally do not put in the back of the electric bicycle and the basket. When it is necessary to move, the charger should be packed with foam plastic to prevent vibration. After the vibration of many chargers, the potentiometer inside them will drift, causing the whole parameter to drift, resulting in abnormal charging state. In addition, it is necessary to pay attention to the ventilation of the charger when charging, otherwise it will not only affect the life of the charger, but also affect the charging state due to thermal drift. This will damage the battery. Therefore, it is also very important to protect the charger.

Recharge your batteries every day

Even if you do not require long battery life, you can use it for 2 to 3 days on a single charge, but it is recommended that you charge it every day, so that the battery will be in a shallow cycle and the battery life will be extended. Some early users of mobile phones, think that the battery is best used up after the basic charge, this view is wrong, lead-acid battery memory benefits are not so strong. Frequent discharge of the battery life of the impact is greater. Most chargers charge 97 to 99 percent of their batteries after the indicator light changes to indicate that they are fully charged. Although only 1% ~ 3% of the battery is undercharged, the impact on the ability to continue to run can be almost ignored, but also the formation of undercharged accumulation, so after the battery is charged with electric transformer lamp or continue to float charging as far as possible, is also good for the inhibition of battery vulcanization.

4. Timely charging

After the battery discharge began the vulcanization process, in 12 hours began, there is a significant vulcanization. Timely charging, can remove the serious sulfide, if not timely charging, these sulfide crystals will accumulate and gradually form coarse crystals, the general charger is powerless to these coarse crystals, will gradually form a decline in battery capacity, shorten the service life of the battery. Therefore, in addition to charging every day, we should also pay attention to charging as soon as possible after using, so as to make the battery power in a full state.

5. Regular deep discharge

A regular deep discharge of the battery also helps "activate" the battery, slightly increasing its capacity. The usual method is to discharge the battery completely at regular intervals. The method of full discharge is to cycle to the first under-voltage protection under normal load conditions on a flat road surface. Note that we place special emphasis on the first under-voltage protection. The battery in the first under-voltage protection, the battery after a period of time, the voltage will rise, and return to the state of non-under-voltage, at this time if the use of the battery, the battery is very harmful. After complete discharge, the battery is fully charged. It will feel like the battery capacity has been increased.

Develop some good habits of saving electricity

Use taxiing whenever possible. For example, when it going downhill, you can try to slide down before power cut. Taxi is ahead of the traffic lights to minimize braking. A friend of mine told me that it made sense that he would rather turn around once more than brake once

When starting, it is better to add cycling assistance, which can not only improve the starting speed, but also reduce the loss of battery power and life damage.

7. Pay attention to the charging environment

Charging the best environment temperature is 25 ℃. Now most of the charger did not adapt to the environment temperature automatic control system, so most of the charger is designed according to the environmental temperature 25 ℃, so in 25 ℃ under the condition of charging is better. Otherwise, it is hard to avoid the problem of under-charging in winter and over-charging in summer. And ambient temperature at 25 ℃ real time is less, so it must be summer winter owe battery problem. Fortunately, most families now have indoor temperature regulation conditions, so, when charging, it is best to arrange the battery and charger in a ventilated and temperature regulation environment.

In particular, the battery in the northern winter in the low temperature outside into the warm indoor state, the battery surface will appear frost condensation. In order to avoid battery leakage caused by frosting and condensation, the battery should be charged after the battery temperature rises close to the indoor temperature and dries out

8. Make full use of maintenance conditions

Many e - bike dealers can provide battery maintenance and repair services, should make full use of these services. Some brands of electric bikes have proposed battery repairs. For example: regular maintenance of the battery can reduce the damage to the battery. Fixing the battery's charged state can ease the failure of "dead batteries," which is easy for dealers equipped with maintenance capabilities. For water loss, rehydration at 70% of the battery capacity is better than rehydration at 40% of the battery capacity. Even some brands suggest that failing to repair the battery within a specified time is equivalent to giving up the battery warranty. Make consumer suffer the loss that should not happen. Therefore, consumers should make full use of the condition of battery maintenance to extend the service life of the battery.

The correct use method of lithium battery in electric vehicle is as follows:

1. The battery does not need to be "activated"

Lithium batteries do not need the first three charges more than 12 hours, lithium batteries have no memory.

2. Battery charging

Use the charger specified by the manufacturer for charging. Pay attention to whether the charger model matches the battery model when charging.

3. Avoid high temperature charging

Lithium-ion batteries do not charge under the environment of temperature more than 40 °, high temperature can make the battery capacity decline.

4. Timely charging

Lithium battery with the implementation of as far as possible with charge, avoid the battery every time under voltage after recharging, which can greatly improve the battery life. 5, store

Do not use the battery for a long time should be disconnected from the car battery, and interval of time to add some battery power, avoid self-discharge of the battery, or the power consumption of the protection plate will put the battery.
