What are the hazards of long charging time for car lithium batteries?

Generally speaking, it will take longer to charge a newly purchased electric vehicle. Of course, this is an electric vehicle with a lead-acid battery. The lithium iron phosphate battery electric vehicle can be fully charged, do not activate, the lithium battery will naturally activate when the electric vehicle is driving. If you deliberately want a 12-hour long charge activation method for a new battery, it would be a waste of time. Of course, frequent charging for a long time is likely to cause premature loss of battery electrolyte, thereby affecting the battery's service life. Overcharging leads to a decrease in battery life, and overcharging can cause a large amount of gas to wash the battery plates, causing active materials to fall off, and ultimately reducing battery life. Of course, the general lithium battery will automatically turn green when fully charged. At this time, it will always be charged with a small current to ensure the safety of the battery. The charging time is best according to the specification, 48V/20A lithium battery, the charger is 5A, it needs to charge a little more than 4 hours, if it is a 10A charger, it is a little more than two hours, 20A charging Charge the device for one hour. Charging Tips for Lithium Battery of Electric Vehicles 1. Do not recharge after the battery is completely used up, charge it when the meter shows two lights left, because strictly speaking, the lithium battery cannot be overcharged or overdischarged. 2. Don't put flammable objects nearby when charging, and don't cover the charger with sundries to ensure accidental fire. 3. After the light turns green, power off after charging for 1-2 hours. 4. Remember to plug in the battery end plug first, and then the mains plug when charging; pull out the mains plug first, and then the battery end plug after charging. 5. Do not charge for more than 8 hours after the green light. 6. Please do not manually discharge the lithium battery by short-circuiting for deep discharge. Do not charge the lithium battery for more than twelve or even twenty-four hours frequently. Statement : Some pictures and content of articles published on this site are from the Internet.
