With the continuous increase in the price of electric vehicle batteries, it is more important to learn how to maintain the battery maintenance of electric vehicles. Because the maintenance of electric vehicle batteries can double the battery life of electric vehicles, it is equivalent to saving money!

1. Do not replace the charger casually. 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 speed limit of the controller, although it can improve the speed of some cars, 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 special cases, it must be moved, and the charger should 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. Charge 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 early users of mobile phones think that it is better to recharge the battery after it has been basically used up. 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. Charge in time.

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.

After the battery is discharged, the vulcanization will form quickly. Someone has been tested. After the battery is discharged for 24 hours, the white sulfide can be seen on the electrode plate, and the sulfide is a substance that is very easy to crystallize. Known as "sulfation", referred to as vulcanization, and not charging in time, will accelerate the formation of this vulcanization. The general charging method does not eliminate this vulcanization. Over time, vulcanization will become an important cause of reduced capacity and shortened battery life. If you have any conditions, it is best to purchase a pulse-removing vulcanization and anti-vulcanization device "Lead-acid battery capacity recovery device", which can prevent and eliminate plate sulfide at any time.

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. If you use this type of callback, A few times, it is possible that the battery will be completely scrapped. 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 reduce the brakes once more in the bay. 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 the 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.

Through these methods, the user can greatly extend the battery life. Some users have shorter continuation miles, battery life is relatively longer, and some problems are relatively difficult to find. Therefore, the "deep discharge" measures mentioned in Article 4 are also an effective way to find the battery problem in time, and it is difficult to deal with when the battery problem is serious.

Electric vehicle maintenance precautions

1, diligent charging --- lead-acid batteries should be kept with the habit of charging, can not wait until the battery is recharged, this will affect the battery life. If it is not used for a long time, charge it once a month. Please use the matching dedicated charger for charging.

2, more maintenance --- in case of rain, can not let the water flood the hub center; when the vehicle is off, close the door in time, usually the tires are full of gas; in the case of heavy loads such as uphill and top wind, use the pedal boost In case of failure, it will be sent to the special maintenance department designated by the manufacturer for repair.

3, diligent lubrication - according to the use of the situation, the front axle, rear axle, central axle, flywheel, fork, shock absorber pivot point and other components should be scrubbed and lubricated every six months to one year (recommended to use molybdenum disulfide lubrication fat). The transmission components in the electric hub have been coated with special lubricants, so users do not have to scrub the lubrication themselves.

Extend the life of electric vehicle batteries

1. Charge frequently to avoid “deep discharge”. Riding an electric car should develop the habit of charging on the same day of use. It is best to charge the battery in any way, no matter how far it is riding. Don't wait for it to be recharged. After the battery is discharged, the vulcanization will form quickly. Someone has been tested. After the battery is discharged for 24 hours, the white sulfide can be seen on the electrode plate, and the sulfide is a substance that is very easy to crystallize. Known as "sulfation", referred to as vulcanization, and not charging in time, will accelerate the formation of this vulcanization. The general charging method does not eliminate this vulcanization. Over time, vulcanization will become an important cause of reduced capacity and shortened battery life. If you have any conditions, it is best to purchase a pulse-removing vulcanization and anti-vulcanization device "Lead-acid battery capacity recovery device", which can prevent and eliminate plate sulfide at any time.

2. When the battery is charged in the car, the electric door lock should be closed. Do not charge the battery upside down. When charging, try to fill it once. If there is any smell or the battery temperature is too high during the charging process, stop charging immediately and send it to Lulu Technical Department for overhaul. When removing the battery, do not touch the ends of the electrode with a metal such as a wet hand or a key to avoid burns.

3. When not in use for a long time, it is necessary to charge the battery once every month. It is necessary to store the battery in the battery and store it in a state of loss.

4. Use a special charger when charging. Due to the different battery formula and process, the technical requirements for the charger are different. Which type of charger can be filled with any brand of battery, which is different, so do not mix the charger.

5, in order to protect the battery, the user can use the charge, but can not use the rebound voltage to prevent serious loss of power, when the battery is dead, the power should be turned off.

6. When charging, the charging indicator should not stop charging immediately when it is fully charged, and should be floated for 2-3 hours.
