How to make electric vehicle batteries more durable?

With the widespread use of electric vehicles, the battery replacement cost of electric vehicles continues to rise, and how to extend the service life of the battery has become one of the concerns of customers. So, how to make the battery of an electric car more durable? The reporter knew for a while and summed up the following relevant experience. Lead-acid batteries: At present, most electric bicycles are lead-acid batteries, which are characterized by low discharge current, long power consumption, deep discharge depth, and cannot be charged while driving. The longer the distance, the deeper the discharge depth. The daily travel distance is 30-40km, and the drainage depth is 60%-80%. The battery of an electric bicycle should be a deeply charged power battery. Ni-MH battery: As a sealed battery, the Ni-MH battery is easy to operate in any direction, and the component weight is about 10 kg. Compared with ordinary lead-acid batteries, it not only has low secondary pollution, but also can be charged at any time and can be reused without protection. Taking overcharge and overdischarge as the application process, it is estimated that it can be used about 1000 times. Lithium battery: The lithium battery adopts three-layer protection measures, which can be charged and discharged many times, making it safer and more convenient to use. It has the four major characteristics of small size, light weight, long life, and environmental protection (no need for recycling). A battery weighs only 4 kilograms, about the size of a children's crayon box, and can be placed in a car basket. However, the current electric bicycles on the market are still easy to be lost in recycling, and the colloidal lead-acid batteries that pollute the environment twice. Ni-MH batteries and lithium batteries have good environmental protection effects, but the cost is high, resulting in high prices and low penetration rate of electric bicycles equipped with these two types of batteries. In the future, hydrogen fuel-powered batteries and carbon nanotubes (a container that holds electrical energy like a faucet and discharges it) will become the future of electric bicycles. At eight o'clock, beware of experts reminding you to pay attention to the following eight points when using the battery: 1. After the battery is used up, recharge the battery in time. If the battery is not charged for a long time, the battery will be damaged; 2. When the charging lamp lights up in the future, it means that the battery can be used or is basically sufficient, but it is still far from 100%. It is recommended to charge the battery once a week or every two weeks for a long time. 3. Pay attention to check the tire air of electric bicycles, not too much in summer, try to save enough electricity in other seasons; 4. Do not charge the battery after fully discharged, the deeper the discharge, the shorter the battery life; 5. If the electric bicycle is long When not in use, the battery should be recharged and then placed. The battery must be checked at least once a month. 6. If it is not electric friction, the effect of the new anti-theft device is not great, and the burden of the new battery; 7. Assuming that the riding distance is about 15 kilometers per day, the battery life is estimated to be 2 years; 8. If it is found during the charging process The battery is overheated and should be shut down immediately for quick maintenance. Four defenses extend battery life In order to make the battery work better for electric vehicles, experts believe that it is important to do a good job of daily battery protection. First of all, the battery should be firm in the electric bicycle device, prevent front and rear disassembly, and prevent the battery from being damaged by vibration in different uses. Frequently remove dust and dirt on the battery box, and pay attention to keeping the battery dry and clean to prevent the battery from discharging. Second, the battery is not close to high-temperature heat sources. In the hot season, it is forbidden to expose to the sun (especially in summer car storage). Pay attention to good ventilation when charging, and charge the battery in time for future use. Use of charging can ensure a smooth next trip. . Third, when the electric bicycle is just started, try to use the pedal power to start it to prevent excessive discharge current from damaging the battery. Do not over-discharge the battery when riding a bicycle, which may cause serious battery loss and shorten its service life. Fourth, the overloading of electric bicycles will cause the motor current to increase, leading to battery over-discharge and premature aging of the battery, which seriously affects the battery life. It should be noted that if a battery rupture or electro-hydraulic leakage is found, the battery should be replaced in time to prevent the formation of acid corrosion. The battery electrolyte is corrosive, please do not touch your skin and clothing, and avoid splashing it into your eyes. If the above situation occurs, you should immediately rinse with clean water and immediately send to the hospital for treatment.
