Which methods can improve battery life?

A good way to improve battery life 1. Try to prevent full charge to 100%. Under normal circumstances, the optimal power range of lithium batteries is 30% to 80%. For example, when Nissan Motor sells Lefeng electric vehicles, it recommends that users stop charging when it reaches 80% of the power. This may reduce the driving range of electric vehicles, but it can effectively extend the battery life. In addition, leaving a certain amount of battery capacity can be used for energy recovery when the electric vehicle is braking, because if the battery is fully charged or close to full, in order to prevent the battery from overcharging, the braking energy recovery will be stopped. 2. Regarding pure electric vehicles, try to prevent complete discharge to 0%. Lithium batteries are more suitable for partial discharge cycles rather than deep discharge cycles. Since the lithium battery has no memory effect, there is no need to worry about the impact of shallow charging and shallow discharge of the battery on the battery life. The question consumers often ask is how far can electric cars go? But please try not to run out the battery to test the driving range of the electric vehicle. 3. Regarding plug-in hybrid vehicles, consider using the climbing mode or turning off the electric mode under certain circumstances. Regarding plug-in hybrid vehicles such as Toyota Prius or GM Volanda, they can switch to gasoline mode after the battery power is low, because the battery management system of the vehicle will shut down the battery system in time to prevent deep cycling. But if there is a long climb on the planned travel route, please turn on the climbing mode or turn off the electric mode at least 20 minutes before climbing. 4. Use the charge management system to reduce the high battery state of the battery. Generally speaking, the lithium battery is the most stable in the half-charge state. Therefore, how to keep the battery state stable while ensuring that the battery power meets the travel requirements? Many electric vehicle manufacturers or charging facility manufacturers propose to use smart charging managers to delay charging to reduce the time when the battery is in a high state. The best way is to set the time to reach the required power state about 1 hour from the departure time. On the one hand, this can prevent accidental changes in the itinerary, on the other hand, it can also lower the battery temperature before traveling (the latter one can be ignored in winter, because the charging temperature is beneficial to low-temperature use). 4. However, there are exceptions. When the electric vehicle battery is almost out of power, timely charging becomes more important. 5. In hot weather, try to park in the shade; in cold weather, try to park in the garage. Most electric vehicles have a thermal management system to keep the battery temperature between -6°C and 30°C, which is very important to keep the battery in a healthy state. However, in hot weather, if the thermal management system is not turned off after parking in the open air, the battery of the vehicle may have been exhausted by its own cooling after returning after a few hours; if the thermal management system is turned on for a few minutes and then stopped after parking, the battery in the vehicle will be depleted. The surrounding environment slowly warmed up. Both conditions have an impact on the life of the battery. Another solution is to charge the battery while turning on the thermal management system of the battery after parking in high temperature weather. This can not only maintain the proper temperature of the battery, but also prevent deep discharge. 6. Plan the long-term parking mode in advance. For some models with a storage mode, you can plug in the vehicle and turn on the storage mode; for a car without this function, if you will not drive an electric car for more than a month. You can (1) park the car in a place with a low temperature (but not too cold); (2) charge to 60%; (3) the battery will slowly self-discharge, when the self-discharge reaches 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 charging mileage of an electric vehicle cannot meet the day's travel. However, the battery will pay a price for this convenience. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
