How to extend the life of lithium-ion batteries for electric vehicles

1. Use a suitable charger to prevent the chemical activity of high-current iron-lithium-ion batteries from being much more active than lead-acid batteries. The requirements for chargers are higher. Once a brand-name charger or unsuitable fast charger is used , Not only affects the service life of the lithium-ion battery itself, but also causes an explosion due to the breakage of the diaphragm due to overheating. 2. Do not charge and discharge lithium-ion batteries frequently. Many people think that the number of cycles of lithium-ion batteries in the manual of electric vehicles is hundreds of times as long as they are plugged and unplugged once. In fact, this is a misunderstanding. The manual actually refers to complete re-discharge. Lithium-ion batteries are different from nickel-cadmium batteries. Lithium-ion batteries do not have any memory effect and can be recharged anytime and anywhere. Charging the battery with residual power will not shorten the service life, but can also maintain and extend the battery life. Regarding the recycling cycle, the correct approach for lithium-ion batteries is slow charging instead of deep charging. 3. Do not store the lithium-ion battery of an electric car (18650 batteries) with full power. When you buy it, it is usually 2-3 cells. There are few fully-charged ones. The full-charge storage time is long, which will reduce the capacity of the iron-lithium ion battery. . In addition, it should be noted that the protection board of better quality should be selected. Pay attention to these points, your electric car lithium-ion battery is no problem for five or six years. 4. Do not do the behavior of harming the battery There are many behaviors that harm the lithium-ion battery of electric vehicles, such as excessive discharge, sudden braking, excessive load, series use of new and old batteries, fast charging, overcharging, etc., which will affect the service life of the battery. As a result, its useful life is shortened. 5. Regular maintenance Regularly inspect the outer casing of the lithium-ion battery of electric vehicles to see if there is any deformation, damage, scratches or other problems. If so, go to the repair point for repair in time, and conduct a thorough inspection on it, if the wiring is found If there is corrosion at the end, it should be dealt with in time to avoid leakage.
