Many people want to buy an electric car, but they are afraid that the battery life is short and not disabled. It is difficult to decide. Let's analyze the battery of the electric car. Let's first take a look at what is going on with the battery. There are many kinds of batteries, including lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, and lithium polymer batteries. At present, the power battery commonly used in electric vehicles is mainly a lithium ion battery. The application of lithium-ion batteries in daily life can be seen everywhere, from small smartphones to laptops to lithium-ion batteries. The life of a lithium-ion battery is about 5 to 20 years, with an average of 8 years. However, when the battery capacity of an electric vehicle is reduced to less than 80% of the initial capacity, the driving range of the electric vehicle will be significantly reduced. It needs to be replaced. How long is the life of most electric vehicles? Under the current state of the art, lithium-ion batteries have a service life of about 3-5 years on electric vehicles. There are many factors affecting the battery life of electric vehicles, including: (1) battery working environment temperature. Both high temperature and low temperature will have an impact on battery life; (2) battery charging and discharging methods. High current charge and discharge will also reduce the battery life; (3) battery state of charge, overcharge and overdischarge will have an impact on battery life. In addition, the uniformity of the cells and the difference in the working environment after the battery is grouped will have an impact on the life of the vehicle power battery. A good way to improve battery life 1. Try to avoid full charge to 100%. Under normal circumstances, the optimal power range for lithium-ion batteries is 30% to 80%. For example, when Nissan Motors sells a wind electric vehicle, it is recommended that the user stop charging when charging to 80% of the power. This may reduce the driving range of the electric vehicle, but it can effectively extend the battery life. In addition, a certain battery capacity can be used for energy recovery when the electric vehicle is braking, because if the battery is fully charged or nearly fully charged, in order to prevent overcharging of the battery, braking energy recovery is stopped. 2. For pure electric vehicles, try to avoid full discharge to 0%. Lithium-ion batteries are more suitable for partial discharge cycles than for deep discharge cycles. Since lithium-ion batteries do not have a memory effect, there is no need to worry about the impact of shallow shallow charge on battery life. The question consumers often ask is how far electric cars can go? However, please try not to try to use the battery to test the driving range of the electric car. 3. For plug-in hybrid vehicles, consider using the “climbing mode†or turning off the electric mode in certain situations. For plug-in hybrid vehicles such as the Toyota Prius or General Volanda, the battery can be switched to gasoline mode after the battery is low, because the vehicle's battery management system will shut down the battery system in time to avoid deep circulation. However, if there is a long climb on the planned travel route, turn on the Hill Climb Mode or turn off the electric mode at least 20 minutes before climbing. 4. Use the charge management system to reduce the battery's high battery status. In general, lithium-ion batteries are the most stable in the half-charge state. Therefore, how can we keep the battery state stable while ensuring that the battery power meets the travel requirements? Many electric vehicle manufacturers or charging facility manufacturers have proposed using a smart charging manager to delay charging to reduce the time of high battery state. The best way is to set the time to reach the required state of charge to about 1 hour from the departure time. This can prevent accidental changes in the stroke on the one hand, and lower the battery temperature before travel on the other hand (the latter can be ignored in winter, because the temperature of charging is beneficial for low temperature use). 4. However, there are exceptions. When the battery of an electric car has almost no power, timely charging becomes more important. 5, in high temperature weather, try to park in the shade; in cold weather, try to park in the garage. Most electric vehicles have a thermal management system that keeps the battery temperature between -6 ° C and 30 ° C, which is important to keep the battery healthy. However, in hot weather, if the thermal management system is not turned off after parking in the open air, after a few hours of returning, the battery of the vehicle may have been exhausted by itself; if the thermal management system is stopped after a few minutes of stopping, the battery in the vehicle will be The surrounding environment is slowly warming up. Both conditions have an impact on battery life. Alternatively, the solution is to charge the battery thermal management system while parking in hot weather. This keeps the battery at a suitable temperature and avoids deep discharges. 6. Plan long-term parking mode in advance. For some models with a “storage modeâ€, the vehicle can be plugged in and the “storage mode†turned on; for cars without this function, if you will have more than one month, the electric car will not be turned on. You can (1) park your car in a cooler (but not too cold) location; (2) charge to 60%; (3) the battery will slowly self-discharge, when self-discharged to 20% or 3 months later (whichever comes first), recharge the battery to 60%. 7. Reduce the number of DC fast charging. Fast charging is very useful when the single-charge mileage of an electric car cannot meet the day's travel. However, the battery will pay a price for this convenience. The above is a suggestion to extend the battery of an electric car, but it is not necessary. But the problem of dealing with battery life is enough!
