How many years does a tram battery usually change?

8 years.

After a certain number of years of use, the battery of pure electric vehicles gradually decreases with the attenuation of the battery, and the battery must be replaced, and the cost of replacing the battery is indeed expensive; The battery warranty service of pure electric vehicles is very long, but according to different **, the battery type is also different, so the life is relatively different.

The battery of electric vehicles is changed once every 8 years.

Therefore, it is recommended to replace the battery every 8 years. The battery is an important part of the electric vehicle, which can supply power to all the electronic devices in the car, and the battery can supply power to the electric motor. If you don't have a battery, the electric car won't be able to run properly.

Electric vehicle battery batteries are strictly forbidden to be in a state of power loss when storing. The state of power deficit refers to the fact that the battery is not charged in time after use. Storing the battery in a state of power loss is prone to sulfation, and the lead sulfate crystals adhere to the plates, blocking the ion channel, resulting in insufficient charging and a decrease in battery capacity.

The longer the battery is idle, the more damaged the battery will be. Therefore, when the battery is not in use, it should be replenished once a month, so as to better maintain the health of the battery.

In the process of use, if the driving range of the electric vehicle 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 pack 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 in time for inspection, repair or matching. This can relatively extend the life of the battery pack and maximize cost savings.

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. High-current discharges can easily lead to lead sulfate crystallization, which damages the physical properties of the battery plates.

Electric vehicles should not be left outside when it rains, which can easily lead to paralysis and are easy to deteriorate if they are too many times.

Hybrid vehicle batteries can basically be divided into ternary lithium batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries.

Among them, the first two belong to lithium-ion batteries, ternary lithium batteries have a cycle life of less than 1,000 times, lithium iron phosphate is about 2,000 times, and they are used in hybrid vehicles for about 200,000 kilometers for 10 years of normal use, and the pressure is not large. Even if there is a single damage, the replacement cost is not high, a few hundred dollars a piece, and the overall replacement will basically not occur in the life cycle. It is possible to do it 1000 times under the premise.

NiMH batteries have been used by Toyota Hybrid, with a service life of about 500 cycles, and hundreds of thousands of kilometers without moving the battery abound. With the ultra-long warranty of the hybrid vehicle battery, you can buy it with confidence and do not have to worry about battery life.

Pure electric vehicle battery 1: lead-acid battery.

Lead-acid battery has a long life, generally in years, lead-acid battery, is a battery with electrodes mainly made of lead and its oxide, and the electrolyte is sulfuric acid solution. In the discharged state of lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; In the charging state, the main components of the positive and negative electrodes are lead sulfate.

Pure electric vehicle battery two: nickel hydrogen battery.

Nickel-hydrogen batteries store twice as much energy per unit weight as lead-acid batteries, and other properties are better than lead-acid batteries. ** It is 4-5 times that of lead-acid batteries, and is being vigorously researched to bring it down. Nickel hydrogen battery is charged by constant current charging, according to the battery's ability to accept the current, different currents can be used to charge the battery, and there is no need to limit the voltage of the battery cell during the charging process, and at the same time, fast charging can be realized.

Pure electric vehicle battery three: lithium iron phosphate battery.

Lithium iron phosphate batteries refer to lithium-ion batteries that use lithium iron phosphate as the cathode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in most lithium-ion batteries.

The theoretical life of lithium iron phosphate power battery is 7-8 years.

The battery replacement time of an electric vehicle is not based on a periodic basis. The replacement cycle is mainly determined by its mileage and frequency of use. In general, during the normal use of the battery.

At least he can use it for 3 to 5 years. Because the cost of the battery is also relatively expensive, so. 3 to 5 years is his minimum period of use.

Members of the China Electric Vehicle Alliance replied: The new car must be charged for 12-14 hours 3-4 times before charging in order to activate the battery. In the future, as long as the train runs 1 kilometer, it will have to be charged every day, and the time is 6-8 hours.

The battery of the electric car is not afraid that you will charge, but I am afraid that you will not charge. However, pay attention to the charging time should not be exceeded, if it is overcharged, it will be very bad for the battery and the charger.

Change it every two to three years.

How often to replace the electric vehicle battery has a certain relationship with the service life of the battery, personal maintenance habits, frequency of use, battery quality, etc. Generally speaking, it is better to replace the battery after one and a half years and two years, not more than three years at the latest, if the battery is not replaced for too long, it not only needs to be charged frequently, but also may bury hidden dangers to personal safety.

For people who ride electric vehicles regularly, the loss of the battery will also be relatively large. Generally speaking, replacing the battery after a year and a half or two years will give you a better riding experience. However, if the quality of the battery is relatively good, the battery can be replaced after three years.

But whether to persist for so long and then replace the battery also depends on the performance of the battery and the riding needs.

The importance of daily battery maintenanceSome people do not know how to maintain the battery in their daily life, which can easily lead to the shortening of the battery life. In the hot summer months, some people will put their electric cars in the yard to charge when they see that they are running out of battery. As everyone knows, charging an electric vehicle in a high-temperature environment can easily lead to battery damage and even bury potential safety hazards.

Some people think that you can't wait for the battery to run out of power before charging, so you can charge the electric car when you get home from cycling, so that the battery will not be damaged. Although this will not damage the battery due to power loss, the more frequent the charge, the shorter the battery life. Therefore, if you want the battery of the electric car to last longer, it is good to wait for the battery to only 30% of the battery before charging, and do not need to charge it every time it is used, which will only shorten the life of the battery.

Electric vehicle batteries are generally replaced once every 2-3 years.

Maintenance of electric vehicle batteries:

1. Rigorously choose the charger.

There is a saying that is widely circulated in the industry: the battery is not used badly, it is charged badly. So the choice of charger is very important. The charger used with the car should match the battery pack and meet the requirements of the charger parameter table in this description, otherwise the performance of the battery will be impaired.

2. Accurately grasp the charging time.

In the process of using electric vehicles, the charging time should be accurately grasped according to the actual situation, it is best to charge after the battery uses about 80% of the power, if the battery power is exhausted, the power should be turned off, and the battery should not be used to 'rise voltage' to force driving, so as to prevent shortening the battery life due to 'over-discharge'.

If the battery is charged continuously for more than 10 hours, and the charger still does not change the light or the battery is hot, the charging should be stopped immediately and handed over to the battery after-sales service for processing, and it is strictly forbidden to continue charging without changing the charger.

3. Regular inspection to avoid exposure to the sun.

The battery can not be close to the fire source, heat source, it is strictly forbidden to directly expose to the sun in the hot season, the temperature is too high the environment 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, the shell is heated when charging, the shell is bulging, deformation and other fatal damage. At the same time, it should also avoid violent vibration, collision and short circuit of the positive and negative electrodes of the battery.

4. It is strictly forbidden to put the state of power loss on hold.

The battery charge leaves the factory, usually the user can directly load the car for use, such as a long period of time (more than 2 months) before use should be supplemented, the charger is plugged into the battery box and then connected to 220 volts of AC power, the charger turns green after continuing to charge for 1 2 hours, you can stop charging.

The warranty period for electric vehicle batteries is one year. The battery is the core part of the electric vehicle, in addition to the engine, the battery is the most core part of the electric vehicle, the battery determines the life of the electric vehicle, and the battery of the electric vehicle will decline in battery capacity after a period of use. Behaviors such as deep discharge, high-current discharge, high charging and discharging frequency, short-term charging and failure to charge in time after discharge will reduce the life of the battery.

As a means of transportation, the charging and discharging of electric vehicles are separated, and it is difficult to have the conditions to charge in time after discharge, and the lead sulfate formed after discharge will be sulfurized into crystals if it is not charged for a long time and reduced to lead oxide, which has a great impact on the life of the battery.

Electric vehicle batteries generally have a lifespan of between one and a half to two and a half years, so you can choose to replace the battery in about one and a half to two and a half years.

Service life: Under normal temperature conditions, lithium batteries are counted according to the charge and discharge cycles.

The standard is about 500 times, assuming that one charge a day is underway, the new electric vehicle lithium battery, for ordinary family use, can be used for about two years, for some takeaway and express brother electric vehicle batteries, it may be a year and a half after the need to replace the battery.

Therefore, the battery life of electric vehicles is normally one and a half to two years to need to be replaced, if the cold northern cities, the life of the battery is different, and it will also have a great relationship according to the frequency of charging, so it is recommended to fully charge each time the power is almost finished.

The battery of an electric vehicle can generally last for 2 to 3 years. The main component of an electric vehicle is the battery, and the highest cost is also the battery, and the battery is currently the fastest depletion. If used properly, it is not a big problem for ordinary batteries to last for about 2 years.
