How to use electric vehicle battery correctly

Correct charging and maintenance method of lithium battery for an electric vehicle:

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

2, when the electric vehicle in the process of low battery power, lithium battery should be charged as soon as possible in a timely manner.

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

The battery will activate naturally.

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

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

The lithium electric car is made of the environmentally-friendly and portable lithium-ion battery, which features large capacity, long service life, maintenance-free, lightweight and pollution-free. 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 the lithium battery for reference.

When you buy a new car, in order to transport safety, the battery factory is in the half-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 special charger attached to this car for charging. When the charging indicator is green, please continue charging.)

Do not run out of battery during each ride. If you run out of battery, it will greatly reduce the battery life. Because lithium batteries have no memory effect, they can be charged at any time. So you should develop a 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 expose the battery to rain or water.

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

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

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

The battery cannot be charged with empty, such as empty after recharging, the capacity of the battery will drop by 2%.

2\ if convenient, it can be refilled when 70% is used.

Make sure you have enough charge for 2 hours after the light change, but never more than 12 hours.

4\ usually charging can be according to the consumption of electricity to see the actual time of charging, such as later charging, with the same electricity beyond the usual charging time is too long, to timely power off, send the battery and charger, to prevent the battery is charged drum.

If you don't use it for a long time, you'd better have enough for 20 days or so.

Don't use other people's charger to charge, such as the voltage and the interface of the plus or minus one, will cause damage to the battery.

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 the charger at will when uncertain. If the mileage requirement is long, it must be equipped with multiple chargers for off-site charging. The charger that is fully charged during the day should be used with a supplementary charger, and the original charger should be used at night. Removing the speed limit from the controller may increase the speed of some cars, but it will not only reduce the safety of the car, but also reduce the battery life.

2. Protect the charger

The 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 later think of looking for the manual, often too late, so it is very necessary to read the manual. In order to reduce the cost, the current charger is basically not done high vibration design, so that the charger generally do not put in the trunk of the electric bicycle and the basket. If it is necessary to move, the charger should be packed with foam plastic to prevent vibration. After the vibration of many chargers, their internal potentiometer will drift, making the whole parameter drift, resulting in abnormal charging state. In addition, it is necessary to keep the charger ventilated 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 very important to protect the charger.

Recharge your batteries every day

Even if your endurance is not long, you can use it for 2 to 3 days with a single charge, but it is still 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 thought that it was best to charge the batteries after they were basically used up, which was wrong. The memory benefits of lead-acid batteries were not as strong. Frequent discharge of the battery life of the impact is relatively large. After most chargers are fully charged when the indicator light changes, the battery charge may be 97% ~ 99%. Although the power of undercharge is only 1% ~ 3%, the impact on the range can be almost ignored, but it will also form the accumulation of undercharge, so after the battery is fully charged, the lamp will continue to float charge as much as possible, which is also good for suppressing battery vulcanization.

4. Timely charging

After the battery discharged, the vulcanization process began, and at the beginning of 12 hours, there was significant vulcanization. Timely charging can remove the serious sulfide, if not timely charging, these sulfide crystals will accumulate and gradually form large crystals, the general charger is powerless to these large crystals, will gradually form the decline of battery capacity, shorten the service life of the battery. Therefore, in addition to charging every day, you should also pay attention to charging as soon as possible after using, so as to make the battery power in 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 cycling under normal load conditions on flat surfaces to the first under voltage protection. Note that we place special emphasis on the first under voltage protection. After the battery is under voltage protection for the first time, after a period of time, the voltage will rise and return to the non-under voltage state. At this time, if the battery is used again, it will do great harm to the battery. After a complete discharge, the battery is fully charged. Will feel the battery capacity has increased.

6, develop some good habits of power saving

Use taxiing whenever possible. For example, when going downhill, take advantage of the power cut ahead of time to slow down. Slide in ahead of the traffic light to minimize braking. A friend of mine told me that he would rather make one more turn than one brake, and it made sense

When starting, it is best to add riding power, which can not only improve the starting speed but also reduce the loss of battery power and liver damage.

7. Pay attention to the changing 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 the ambient temperature at 25 ℃ real times 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 the maintenance conditions

Many e-bike dealers can provide battery repair and maintenance services, should make full use of these services. Some brands of e-bikes have proposed battery overhauls. For example, regular maintenance of the battery can reduce the damage to the battery. Fixing the battery's charged state can mitigate "battery lag" failures, which are easy for dealers equipped with maintenance capabilities. For water loss, rehydration at 70 percent of the battery capacity is better than rehydration at 40 percent of the battery capacity. Even some brands suggest that failure to repair within the required 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.
