Bicycle battery/Electric vehicle lithium battery/How many years is the service life of electric vehicle lithium battery?
The service life of lithium batteries for electric vehicles is generally 3-4 years. But this does not mean that the service life of lithium batteries will end after 3-4 years of use. As long as you pay attention to these points, the life of lithium batteries in electric vehicles can be doubled.
Lithium batteries have strict charging times, generally around 1000-1200 times. However, the charging of lithium batteries and lead-acid batteries is completely opposite. It needs to be recharged after being used up. When the battery is not used for a long time, it needs to be fully charged every two months.
Lithium batteries are afraid of cold and heat, so don't use them in extreme environments. Putting lithium battery electric vehicles in the sun in summer, or parked in the yard or on the road in winter, is very detrimental to the service life of lithium batteries. The migration rate and temperature of lithium ions in the electrolyte and electrode sheets Closely related, theoretically the temperature can be used normally between -20°C and 55°C. In daily life, the use temperature of lithium batteries is between 5°C and 35°C. There is no harm to lithium batteries. Northern users try to take lithium batteries home for storage in winter, and do not put them outdoors. Southern users avoid summer exposure.
Lithium batteries for electric vehicles are mainly divided into three categories
First, ternary lithium is also the most common type of lithium battery currently used;
Second, lithium iron phosphate;
Third, lithium titanate. Among them, the popularity of lithium titanate is very low, and the usage rate is less.
How to prolong the life of electric vehicle lithium battery
charge every day
Even if your electric vehicle lithium battery can be used for 2~3 days after a single charge, it is recommended that you charge it every day. Because the lithium battery after use is in a shallow cycle state, charging it every day will prolong the life of the lithium battery of the electric vehicle.
timely charging
Because the lithium battery will enter the vulcanization process after it is discharged, if it is charged in time, the non-serious vulcanization can be removed. Therefore, the lithium battery should be charged as soon as possible after use, and the battery should be fully charged as much as possible.
regular deep discharge
A regular deep discharge of the battery is also conducive to "activating" the battery, which can slightly increase the capacity of the battery. The general method is to fully discharge the battery at regular intervals.
Try to use the original charger
In general, the chargers of various manufacturers generally have individual needs, so don't change the charger at will when you are not sure. In addition, do not remove the speed limit of the controller. After removing the speed limit of the controller, although the speed of some cars can be increased, it will reduce the service life of the battery.
