What are the usages of lithium batteries?

Lithium batteries have been widely used in some electric vehicles. Today, I will explain some methods of using lithium batteries. Charge in time 1. The battery is generally in a charged half-charged state when it leaves the factory. When riding for the first time, it is best to fully charge the battery. On the one hand, self-discharge will reduce the charge of the lithium battery, and it can also activate the active material in it. 2. Don't exhaust the battery every time you ride. Long-term over-discharge will reduce the battery life by 3 times. When the battery is too low when the electric vehicle is riding, it is necessary to decisively stop the charging time. 1. The lithium battery is effective at any time, even if there is 50% of the battery before charging, it does not matter. This is because, It is different from nickel-metal hydride batteries, which have a memory effect while lithium batteries do not. But it should be noted that lithium batteries cannot be over-discharged, as over-discharge will cause irreversible capacity loss. When the machine warns that the battery is low, charging will begin immediately. 2. Don't overcharge. When the charging completion indicator light is on, stop charging. If the battery is not used for a long time, the battery should be taken out of the instrument and stored in a dry and cool place, and charged once within 60 to 90 days to avoid excessive storage time, and the battery will be too low due to self-discharge, causing irreversible capacity loss. Because the best storage state of lithium batteries is half-electric storage. Charging to make up for self-discharge. If the battery is not used for a long time, the battery should be removed from the instrument and stored in a dry and cool place, and charged once within 60 to 90 days to avoid excessive storage time, and the battery will be too low due to self-discharge. Irreversible capacity loss, because the best storage state of lithium batteries is half-electric storage (that is, between 40% and 60% of the nominal capacity of the battery). We know that the highest voltage of lithium batteries is 4.2V. Therefore, storage The voltage is preferably between 3.8V~3.9V, and the capacity at this time is basically half. Use the original charger to charge with the original lithium battery charger as much as possible. The original charger has strong supporting performance and moderate charging rate. Now there are some fast charging piles, which are recommended not to be used. The lead-acid battery charger of the same model cannot be used on the same model of lithium battery. Excessive current charging will also cause greater damage to the internal structure of the battery. The storage temperature environment is relatively wide, ranging from -20°C to 55°C, but in fact the most suitable temperature is room temperature. From the perspective of aging, temperature may be an important reason for the gradual decline of lithium battery capacity.
