The proper use of lithium-ion batteries depends on the understanding of the charge and discharge process of lithium-ion batteries.
I. Charging method of electric vehicle lithium-ion battery
First, the first charge, consistent with the usual charging, without special treatment, charging for eight to twelve hours.
Second, you must use the special charger supplied by the lithium ion battery manufacturer for charging. When charging, you must first connect the output port of the charger to the battery, and then connect the charger to the power supply
Third, because the lithium ion battery has no memory effect, it can be charged as it is used, which is good for the life of the battery. It is suggested that eight to twelve hours can be charged each time, and the longest time should not exceed one day.
Fourth, in the case of long-term non-use, it is necessary to charge the lithium ion battery for two hours every two months, otherwise it will cause battery performance decline. In addition, try not to charge when the battery power is completely finished, it is best to charge with the use of shallow shallow charge.
Second, mobile phone lithium ion battery charging method
1. Lithium-ion batteries generally have a shelf life of 3 years, which will decay quickly after three years, whether they are used or not. Lithium-ion battery fullchargecycle should also pay attention to, is about 400-500 times after decay quickly. It is to see you use 3 years or first charge to the number of times.
2, lithium ion battery in addition to the fear of low power, and is afraid of heat, especially when charging, if the mobile phone case heat loss should pay attention to remove. The best way to keep lithium-ion batteries for a long time is to charge them to 40% and put them in the refrigerator, but don't freeze them.
Don't always wait until the battery runs out to charge, it will speed up the loss of it. The loss of lithium-ion battery is relatively large when it is in low power. A long-term battery of 40%-60% can make it live the longest. However, it is impossible for frequently used equipment, but you can make it always at 100%, that is to say, it is often charged and does not pull out after washing. It is not overcharged, and the power is used at this time, the battery will not waste Chargecycle, so it is conducive to prolong the life of the Chargecycle.
4, lithium ion battery can be used when charging, the battery is not discharging while charging, there are two circuits in the mobile phone, one to charge the battery, the other directly through AC power supply to the machine.
5, after charging, connected to the power supply will not cause any harm to the lithium ion battery, because it is directly powered by the power supply, which reduces the number of charging but also conducive to prolong the battery life.
6, (subject to debate) always charging the battery at more than 90% but less than 100% is also not good for lithium-ion batteries, i.e. always "toppingoff". ThinkPad laptops have a mechanism that keeps the battery from charging for more than 90% of the time.
7. There's no harm in charging overnight because you're not using it and it won't heat up. Personally think overcharge is always not a good thing, it is best not to charge at night, in some areas at night voltage instability, harmful to the machine!!
