How to make the battery life of electric vehicles longer

The principle of lead-acid battery is multi-purpose, multi-flush life will be long, and it can be used for about 4 years.

Take good care of it! Supplement the first floor also do not over-discharge and do not overcharge, if not, it is best to replenish once a month.

It is impossible to improve the service life of electric vehicle batteries, but only to ensure the service life of electric vehicles as much as possible.

Charge in time. Vulcanization begins after the battery is discharged, and obvious vulcanization will occur after 12 hours, and timely charging can remove the vulcanization that is not serious. If not in use for a longer period of time, the battery should be stored fully charged and recharged once every 15 days to a month.

Hydrate promptly. The electric vehicle battery is designed with a poor liquid, and during the charging process, the battery will have gas deformation, resulting in a gradual decrease in the distilled water in the electrolyte in the battery, so check whether the battery is short of water every six months or so, and if it is found that there is a lack of water, it is necessary to replenish the distilled water in time.

The battery life is generally 300 times of full charge and discharge. The battery is a consumable, and it is very high, so it is very necessary to use and maintain the battery correctly and extend the service life of the battery to achieve the best use of the battery.

The battery life is generally calculated by the number of times the battery is fully charged and discharged, and the 300 times is calculated by the battery capacity dropping to 75% of the nominal capacity, this data is very important, because the user will not charge the battery when it is only 75% of the capacity, but when there is really no way to use it, the battery capacity has dropped to 40% of the nominal capacity, that is, there is an overdischarge.

Therefore, in order to prolong the service life of the battery, it is necessary to carry out certain maintenance and maintenance.

It is important to keep the battery fully charged at all times. If it is an electric car, do not wait for the battery to run out of power before charging, save.

If the battery is less than half of the charge, it must be charged.

Charging time. Strictly follow the provisions of the manual. If yes.

Motorcycles, cars.

and portable lights.

of the battery, often observed.

Electrolyte level height, below.

Tick marks are added.

Distill water to a normal liquid level, never add electrolyte. When you need to charge, charge slowly with a small current and try not to take it.

High current fast charging.

way to charge. If the vehicle is parked for a long time, remove the battery and charge it once a month, otherwise the battery will be scrapped. Under my careful maintenance, my lord.

It has been four years since the leopard was drilled, and the battery has not stored enough electricity. Correct use and maintenance will significantly improve the service life of the battery and even the whole vehicle.

When the battery of an electric vehicle is stored, it should be stored after it is fully charged, and it should be taken out for discharge or used once or twice in a month or so, and then charged and continued to be stored; This is conducive to prolonging the service life of the battery; Generally, the first three charges of a new battery are best in 8-12 hours, and then it can be mastered in 6-8 hours; It doesn't matter how fast or slow the battery is charged; The key is the discharge time; It can be used for a long time after discharge; As long as the battery can be charged and discharged, it can continue to be used; If you buy a big domestic brand, you can; If you can identify the quality of the product, you can also buy the brand products of small and medium-sized manufacturers; This is more cost-effective; Battery bulging is generally due to air leakage and deterioration, and it is usually the beginning of being unable to continue to use (because some less serious, or better quality batteries can still be barely used); If the battery is bulging, it has no effect on the life of the device; However, some batteries are prone to bursting after the bulging; In the small space of the equipment, it is easy to damage the equipment; Therefore, do not use the battery after the drumming; Generally, the life of the battery is determined by the number of times it is charged and discharged; Generally, the number of recharged batteries for repair and refurbishment is about 50 times, so when you buy, you will swear to tell you that the warranty is three months or half a year; Once the warranty period is over, it will definitely not be long; The number of charging and discharging of batteries produced by ordinary manufacturers is about 100-180 times; The term of use is about one to two years; The battery charged and discharged by a good manufacturer is about 200-300 times; The term of use is about two to three years; The imported and original batteries can be charged and discharged more than 500 times, and the service life is longer; The most taboo of general batteries is overcharging and overdischarging; As long as these two principles are followed, the maximum use and maximum service life of the battery can be used.

Doing the following things can delay life:1Do not store the state of power loss, which means that the battery is not charged in time after use, which is prone to sulfation, and the lead sulfate crystals are attached to the plate, resulting in insufficient charging and a decrease in the capacity of the battery.

When the battery is not in use, it should be charged once a month to keep the battery healthy. 2.If the driving range of the electric vehicle suddenly drops in a short period of time, it is likely that at least one battery in the battery pack has a short circuit.

It should be inspected, repaired or matched by a professional battery repair institution in time. 3.Do not discharge high current When the electric vehicle is starting, carrying people, and going uphill, please use the pedal to help and try to avoid instantaneous high current discharge.

How to extend the service life of electric vehicle batteries? In this way, the battery is immediately scrapped, and the merchant does not include after-sales service.

The newly bought electric car should be discharged, and then once sufficient for 14 hours, three times in a row, and charged in time in the future use, not all used up and then charged.

First, the quality of the battery itself should be good.

Second, the power usage is about 30% and it has to be charged.

3. When not in use for a long time, it should be fully charged first. Drain the electricity for about a month, and then leave it sufficiently.

Fourth, do not lose electricity.

Electric vehicles are generally lead-acid batteries, unlike mobile phone batteries that have a memory effect, so it's okay when you rush it, and it doesn't affect if you can't unplug it Note, bad batteries are generally caused by overcharging and overdischarging, and you must pay attention to the floating charge for 20-30 minutes after charging, and a single charge should not exceed 6 hours, otherwise it will cause overcharging!! Most batteries are overcharged.

Battery maintenance doesn't play a big role. As long as the electricity is used up, it can be fully charged. Generally, it can be used for about 1 or 2 years...

First of all, there must be a correct way to use it, 1: Do not attack the battery violently, (take a very bumpy road, the battery is not very stable, or bump the battery) 2: Even if the battery liquid is replenished (in winter, it is appropriate to supplement less stock solution) 3:

Try to keep the surface of the battery clean 4: If you don't use the battery for a long time, keep it charged once every 2---3 months, 5: Try not to discharge it all at once (this will cause great harm to the battery).

These are the daily maintenance methods of the battery, I hope it will help you, and I hope you can adopt it!

I'm an electric vehicle engineer at Epson.

1. It should be charged in time, and it is better to recharge it with about 70%;

2. Do not store the car for a long time, it will be scrapped after more than two months, and the damage will be more serious in the state of power loss;

3. Do not often overload operation, the standard counterweight is 75 kg, overload will cause early retirement of the battery;

4. On rainy days, the water level on the road should not exceed the motor shaft, otherwise the motor is easy to burn out;

5. Try to assist the start as much as possible when starting, so that the battery damage is slower;

6. After a week of riding a new car, check the standard parts of each part, and it is best to let the sales point overhaul it.

Ninety-five percent of today's electric vehicle batteries are "lead-acid maintenance-free valve-regulated sealed batteries", which do not need maintenance and can be used until it is scrapped.

As long as you don't overload it often in use, and don't discharge it deeply (that is, you don't run out of electricity), it won't cause damage to the battery!

It is also important to note that the battery can not be placed for more than two months at most, and the damage to the fully charged battery is small, and the damage to the battery is greater!

Seventy percent discharge before charging is recognized as the best method in the industry!

You don't need to charge it every day, it's very annoying to charge every day, as long as you can guarantee that you don't use electricity at all.

The so-called 70% is the data calculated according to the battery discharge curve, which is the ideal discharge standard.

Besides, if it's broken within the expiration date, find a point of sale to replace it with a new one! Half a year for a new one, 8 months for a standby, a year for maintenance, more than a year to care.

1) Charge frequently, 2) Prohibit positive and negative short circuits.

The electricity should be completely used up before charging, not charging before it is used up.

1. Reduce high-current discharge; Use foot pedal assistance when starting and going uphill; Avoid carrying heavy items, preferably no more than 75 kg; Always check your tires for full air.

2. Prevent over-discharge; Electric vehicles are generally equipped with under-voltage protection function, when the battery power indicator only one indicator light is on or when the power indication is in the ** area, the battery should be charged immediately, and the ride should not be continued. The power lock should be turned off immediately when not in use.

3. Referring to the usual riding conditions and the configuration of electric vehicles, it is best to charge the battery once when the discharge depth is 50-70, and it can be converted into riding mileage when it is actually used, and it can be charged once when needed. A three-stage pulse charger is used to delay the generation of irreversible vulcanization, and the battery is recharged once a month during storage.

6. Carry out a deep discharge every two months, that is, ride for a long distance until the undervoltage indicator flashes, the power is used up, and then the battery capacity is restored. When the battery capacity is reduced to 60-70 of the original capacity, it should be restored and maintained in time.

7. When the battery is charged, it is found to be hot, and the charger does not change the red light and the green light is green, and the professional restoration and maintenance will be carried out in time the next day; Otherwise, the battery will be swollen and scrapped within a few days.

8. The purchase of electric vehicles should be based on practicality, and the purchase of ultra-high-power electric vehicles should be avoided; The more powerful the motor, the shorter the battery life.

1. What is the service life of the electric vehicle battery?

A: The electric vehicle battery depends on what brand you use. The average garbage battery has a service life of -1 year. The general brand battery is about -1 and a half years. Big brand batteries are generally 2 to 2 and a half years old. It can even be longer.

1. Keep the battery in a fully charged state, ride an electric moped every day, no matter 10-15km, it should be replenished and charged, so that the battery is in a "full state" for a long time, and it will be charged on the same day, and it will be charged again after a few days of idleness, which is prone to extreme vulcanization and reduced capacity.

2. Carry out regular deep discharge: It is recommended that you use it for two months and carry out 1 deep discharge, that is, long-distance riding only to the undervoltage indication flash, and the power is used up to make you know the current capacity level of the battery and whether it needs to be maintained.

3. It is forbidden to store the battery with power loss: the storage of the battery will seriously affect the service life, and if the idle time is longer, the battery will be damaged.

4. Regular inspection: If you buy a new car for 50km, within three months there is a serious reduction in the continuation, such as more than ten kilometers, at this time you can use a multimeter to check the voltage value of the external terminal post of the battery, the general full charge should be 39-42 volts, if it is a few volts less, or open the battery box One of the battery voltages is lower than volts, it may be an internal single-grid short circuit, at this time you should find a maintenance station to repair and replace, so as not to damage the other two good batteries. The charger should also be checked for malfunction.

5. The design load capacity of the electric vehicle is 75kg, so avoid carrying heavy objects, and please use your pedals to help when starting and going uphill. Because the motor current increases at this time, the battery is discharged too quickly and the voltage drops rapidly. The smaller the discharge rate of the battery per use, the longer the life of the capacitor.

Therefore, reducing high-current discharge can prolong the battery life and increase the driving range. In addition, no matter how large the capacity of the battery is used, users should develop a good habit of charging at any time.

6. It is normal for the battery capacity to drop with the drop in temperature in winter, with 25 as the standard, and the general -10 capacity is 80%.

7. Keep the surface of the battery clean for a long time, prohibit exposure to the sun when storing the car, and place the car in a cool, ventilated and dry place.

8. During the use of the charger, try to use the original charger as much as possible to avoid short circuit caused by the opposite output voltage, which will burn the charger and seriously affect the battery life. It is recommended to use a smart charger that can adjust the constant voltage value according to the temperature and set parameters.

9. Braking and starting again during the driving of the electric vehicle will cause damage to the battery and affect the mileage, so avoid frequent braking and starting.

10. At present, the widespread use of electronic speakers consumes a lot of power and damages the battery greatly, so it is recommended to avoid frequent use as much as possible in use.

11. When the temperature is high in summer, the charging should be in a cool and ventilated place. It is best to charge for 2-3 hours and recharge after an interval of 1 hour. When the temperature is low in winter, try to replenish the electricity indoors.

1.Do not store the battery at a loss of power: The state of power loss refers to the fact that the battery is not charged in time after use, resulting in insufficient charging and a decrease in the capacity of the battery. The longer the idle time, the more serious the damage to the battery. When the battery is not in use, it should be charged once a month, which can extend the life of the battery.

2.It is necessary to regularly inspect that in the process of use, if the driving range of the electric bicycle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery group has a short circuit phenomenon such as broken grid, plate softening, and plate active material falling off. At this time, you should go to a professional battery repair institution for inspection and repair in time.

3.Do not discharge high current When the electric bicycle is starting, carrying people, and going uphill, it is best to use the pedal to assist and try to avoid instantaneous high current discharge. High-current discharge can easily lead to lead sulfate crystallization, which damages the physical properties of the battery plates.

4.In general, the battery is charged at night, and the average charging time is about 8 hours. If it is shallow discharge (the mileage is very short after charging), the battery will be fully charged quickly, and if it continues to charge, it will be overcharged, causing the battery to heat up and reduce the battery life.

Therefore, it is best to charge the battery once when the discharge depth is 60%-70% (down two grids), and it can be converted into riding mileage when it is actually used, and the necessary charging is carried out according to the actual situation to avoid harmful charging. Deep discharge once a month (to undervoltage in charge).

5.Protect from high temperature exposure. The environment with too high temperature will increase the internal pressure of the battery and make the battery pressure limiting valve forced to open automatically, the direct consequence is to increase the water loss of the battery, and the excessive water loss of the battery will inevitably cause the battery activity to decline, accelerate the softening of the plate, and the shell heats up, the shell bulges, deforms and other fatal injuries during charging.

6.In winter, the battery should be heated indoors for two hours before being recharged.
