Generally, lithium batteries can be used for 3 to 5 years. The battery is a wearing part of electric vehicles that must be replaced regularly. As the number of charges and discharges increases, the battery performance also decreases, so the battery needs to be replaced regularly. There are two types of batteries commonly used in electric vehicles, one is lead-acid battery and the other is lithium battery.
During the charging and discharging process, the battery ions will move in the electrolyte, and some ions will chemically react with the electrolyte when they move in the electrolyte.
As the number of charges and discharges increases, the number of ions in the battery will continue to decrease, so the battery performance will also decrease.
If you can maintain good driving habits, you can extendeffectively extend battery life.
When using your car, it is recommended that you use a suitable charger and take care to avoid overcharging and over-discharging the battery.
If the battery is overcharged or discharged, its performance will be reduced and its lifespan will also be reduced.
If you do not need to use the car for a long time, you should also charge the battery regularly, otherwise the battery will be discharged for a long time.
If the battery is left without power for a long time, the battery life will be shortened and its performance will also be reduced.
Do not charge immediately after riding. At this time, the battery temperature is relatively high. If you charge it immediately, the battery temperature will continue to rise and the battery will be damaged.
What is the general lifespaneral of lithium batteries for electric vehicles?
About three years.
Lithium-ion electric vehicles equipped with lithium batteries as the main power source have also invaded ordinary people's homes. Compared with traditional lead-acid batteries, lithium-ion batteries have the advantages of being light and long-lasting. Long life, high energy density and fast charging. Quick benefits and more. The lifespan of most lithium batteries is designed to be about 1,000 times longer (ordinary ternary lithium battery materials), or 3 to 4 years. But this does not mean that the lithium battery life will end after 3-4 years of use. As long as you pay attention to these points, the life of the lithium battery of electric vehicles can be doubled.
Detailed information:
When charging the electric vehicle battery in the vehicle, the electric door lock must be closed. Do not charge the battery backwards. When charging, try to charge it fully immediately.
When the electric vehicle battery is not used for a long time, it should be charged once a month. Store the battery once it is fully charged. Do not store it in a depleted state.
When using the battery charger, use the corresponding charger. Since the battery raw materials and production processes of lithium batteries are different, the technical requirements of chargers are also different, so special chargers must be used for charging.

The lifespan of lithium battery is "500 times", 500 times of charge and discharge, if it exceeds this number, the battery is "end of life ".
The lifespan of a lithium battery is “500 times”, which does not refer to the number of charges, but to one cycle of charging and discharging.
A charge cycle means that all of the battery's energy is used from full to empty, then charged from empty to full. This is not the same as a single charge. For example, a lithium battery only uses half its power the first day and then charges slowly. If it is still the same the next day, i.e. if you charge it half and charge it twice in total, this can only be counted as one charging cycle and not two.
Therefore, multiple charges may typically be required to complete a cycle. Each time a cycleAfter charging is completed, the battery capacity decreases a little. However, this reduction in power is very small. High quality batteries retain 80% of their original capacity after being charged several times. Many lithium-ion powered products are still in use after two or three years. Of course, lithium batteries still need to be replaced once their lifespan is reached.
How to identify?
1. Compare battery capacity.
General nickel-cadmium batteries have a capacity of 500 mAh or 600 mAh, and nickel-hydrogen batteries are only 800-900 mAh; while the capacity of lithium-ion batteries for mobile phones is generally between 1300-1400 mAh, so lithium batteries are used. once they are fully charged, the time is about 1.5 times that of nickel-hydrogen batteries and about 3.0 times that of nickel-cadmi batteriesum. If you find that the lithium-ion cell phone battery you purchased does not work as long as advertised or specified in the manual, it may be counterfeit.
2. Look at the plastic surface and the plastic material.
The original battery has a uniform wear-resistant surface and is made of PC material, which is not brittle. Counterfeit batteries do not have a wear-resistant surface or are too rough and are made from recycled materials. are prone to fragility.
3. Measure the charging voltage of the battery pack.
If a nickel-cadmium or nickel-hydrogen battery pack is used to simulate a lithium-ion cell phone battery pack, it must be composed of 5 single cells. The charging voltage of a single battery generally does not. exceeds 1.55 V and the total battery pack voltage does not exceed 1.55 V. More than 7.75 V When the tIf the total charge voltage of the battery pack is less than 8.0 V, it may be a nickel-cadmium or nickel-hydrogen battery.
4. For original batteries, the color and texture of the battery surface should be clear, uniform, clean, without obvious scratches or damage; the battery brand must be printed with the model, type and rated capacity of the battery. , standard voltage and normal voltage. Negative pole mark, manufacturer name.
It must be smooth and unobstructed, have a suitable seal, fit the hand well and have reliable locking; the material must not have obvious scratches or black or green spots. If the battery of the cell phone we buy does not conform to the above phenomenon, we can initially conclude that it is fake.
5. From their own point of view, many mobile phone manufacturers have made efforts to improveenhance their know-how to make mobile phones and their accessories more difficult to counterfeit, thus further curbing the proliferation of counterfeits and parallel imports.
As a general rule, classic mobile phone products and their accessories should have a consistent appearance. Therefore, if we install the battery of the cell phone we purchased, we should carefully compare the body and the bottom case of the battery? If the color matches, it is an original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.
6. Observe charging anomalies. Generally, genuine cell phone batteries must have an overcurrent protector inside, which automatically cuts off the circuit when an external short circuit causes excessive current to avoid burning or damaging the phone. The batteriesithium-ion also have an overcurrent protection circuit, which can be; used when non-standard electrical appliances are used, when the power supply current is too large, the power supply will be automatically cut off, resulting in charging failure under normal conditions of the battery, it can automatically return to the conductive state. If during the charging process we find that the battery seriously overheats, smokes or even explodes, it means that the battery must be fake.
