How to protect electric vehicle battery, how to maintain electric vehicle battery

With the constant price increase of electric vehicle batteries, it is more important to learn how to do a good job in electric vehicle battery maintenance, because electric vehicle battery maintenance method can double the life of electric vehicle batteries, which is equivalent to saving money!

1, do not change the charger, do not remove the speed limit of the controller.

Each manufacturer's charger generally has a personalized demand, in the uncertain time do not change the charger at will. If the mileage requirement is relatively long, multiple chargers must be provided for remote charging. The chargers that are recharged during the day are added with additional chargers and the original chargers are used at night. Removing the speed limit of the controller, although it can increase the speed of some cars, in addition to reducing the safety of the car, it will also reduce the service life of the battery.

2, protect the charger.

The general instruction manual has instructions on the protection of the charger. Many users do not have the habit of reading the instructions. They often think of looking for the instructions after the problem. It is often too late, so it is very necessary to read the instructions first. In order to reduce costs, the current charger is basically not designed for high vibration resistance. In this way, the charger is generally not placed in the trunk and basket of an electric bicycle. In special cases, you must move the charger and pack it with foam to prevent vibration. After many chargers have been vibrated, their internal batteries will drift, causing the entire parameters to drift, causing the charging state to be abnormal. In addition, it is necessary to pay attention to maintaining the ventilation of the charger when charging, otherwise it not only affects the life of the charger, but also affects the heat drift and affects the charging state. This will damage the battery. Therefore, it is also very important to protect the charger.

3,Charge every day.

Even if your ability to continue is not long enough and can be used for two to three days at a time, it is recommended that you charge every day so that the battery is in a shallow cycle and the battery life is extended. Some early cell phone users thought that batteries were best to be recharged after basic use. This is not true. The memory efficiency of lead-acid batteries is not so strong. Frequent discharge of electricity has a greater impact on battery life. Most chargers may be 97 to 99 after the indicator lamp is changed to indicate full power. Although only 1 to 3 batteries are undercharged, the impact on the renewal ability is almost negligible, but under-charging accumulation can also be formed, so the battery will continue to float charging as much as possible after being filled. It is also good for inhibiting battery vulcanization.

4, charging in time.

After the battery discharge, the vulcanization process began. At the beginning of 12 hours, obvious vulcanization occurred. Charging in a timely manner can remove the non-serious vulcanization. If not charging in a timely manner, these vulcanized crystals will accumulate and gradually form coarse crystals. The general charger can not do anything about these coarse crystals and will gradually form a reduction in battery capacity. Shorten the battery life. Therefore, in addition to daily charging, it is also important to note that after the use of early charging, as far as possible to keep the battery in full state.

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 "Sulfate", 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.

The periodic deep discharge of the battery also facilitates the "activation" of the battery, which can slightly increase the battery capacity. The general method is to perform a complete discharge of the battery at regular intervals. The method of complete discharge is to cycle to the first under pressure protection under normal load on a flat road surface. Attention, we stress the first case of stress protection. After the battery is under pressure for the first time, after the battery has been under pressure for some time, the voltage will rise and return to non-low pressure. At this time, if the battery is used again, the battery will be very harmful. If you use this call back to ride several times, That could lead to the battery being completely scrapped. After completing the complete discharge, the battery is fully charged. It feels like the battery capacity has increased.

6,Develop the good habit of saving electricity.

Use gliding as much as you can. When the following slope, as far as possible to use the early power loss slide to slow down. Slide in advance when you are about to encounter a traffic light to minimize braking. A friend of mine told me that it made sense for him to reduce his brakes by turning the bay one more time.

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

7, pay attention to the charging environment.

The optimal ambient temperature for charging is 25 °C. Most chargers now do not have automatic control systems that adapt to ambient temperatures, so most chargers are designed at ambient temperatures of 25 °C, so charging at 25 °C is better. Otherwise, the problems of undercharging in winter and overcharging in summer are inevitable. The ambient temperature is really less at 25 °C, so there must be a problem of under-charging in summer and winter. Fortunately, most homes now have indoor heating conditions, so when charging, it is best to place the battery and charger in a ventilated and temperature-adjusted environment.

What is particularly revealing is that when the battery enters the warm room at a low temperature outside in the northern winter, Frost condensation occurs on the surface of the battery. In order to avoid the battery leakage caused by frost condensation, the battery should be recharged after the temperature rises to be close to the indoor temperature and dry.

8, make full use of maintenance conditions

Many electric bicycle dealers can provide battery maintenance and repair services, and should make full use of these services. Some brands of electric bikes are proposed for battery overhaul.

For example, regular maintenance of the battery can reduce the damage to the battery. Repair of the battery's charge state can alleviate the failure of the "battery lag", which is easy for dealers equipped with maintenance capabilities. For water loss, water replenishment is better when the battery capacity is 70 <UNK> than when the battery capacity is 40 <UNK>. Even some brands of products have suggested that not overhauling at the specified time is equivalent to giving up the battery warranty. To make consumers suffer losses that should not have happened. Therefore, consumers should make full use of the conditions of battery overhaul to extend the battery life.

Through these methods, users can greatly extend the service life of the battery. Some users have relatively short range, battery life is relatively long, and some problems are relatively difficult to find. Therefore, the "deep discharge" measures referred to in Article 4 are also an effective way to detect battery problems in a timely manner, and do not wait until the battery problems are serious to deal with.

Attention to maintenance of electric vehicles

1,Rechargerment-lead-acid batteries should be kept in the habit of charging with use, and should not wait until the battery is used up again, which will affect the battery life. If it is not used for a long time, charge it once a month. Please use a dedicated charger for charging.

2, more maintenance-in the event of rain and water, do not let water flood the hub center; When getting off the bus, close the electric door in time, and usually fill the tire with air; In the case of uphill, top wind and other heavy loads, use pedals to help; In case of failure, send to the manufacturer's designated special maintenance department for maintenance.

3, diligent lubrication-according to the use of conditions, the front axle, rear axle, middle shaft, Flywheel, front fork, shock absorber rotation fulcrum and other parts should be scrubbed and lubricated once every six months to one year(recommended to use Molybdenum disulfide lubrication grease). The transmission parts in the electric hub have been coated with special lubricants, and users do not have to scrub and lubricate themselves.

Extending 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. 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 "Sulfate", 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 charging 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 it is not used for a long time, it must be charged once every month. The electricity in the battery must be filled and stored. It must not be stored in a state of loss.

4, when charging to use a matching special charger. Due to different battery formulas and processes, the technical requirements for chargers are not the same. What type of charger can be filled with batteries of different brands, so do not mix chargers.

5, in order to protect the battery, users can use with the charge, but can not use the rebound voltage to prevent serious power loss, when the battery is out of power, should turn off the power riding.

When charging, do not stop charging immediately when the charging indicator shows full power, and should be floating for 2-3 hours.
