Lithium-ion batteries have different charging and discharging characteristics and performance parameters than nickel-metal hydride batteries. The use and maintenance of power lithium batteries for electric bicycles are not much different from those of ordinary lithium batteries. Here is how to use power better. The method of lithium battery.

   1. Timeliness of charging: (1) When the battery is shipped from the factory, it is usually charged with a semi-electric state. When riding for the first time, it is best to fill the battery. One self-discharge will reduce the charge of the lithium battery, and the other will activate the active substance. (2) Do not exhaust the battery every time you ride, because over-discharge is very harmful to the lithium battery. Long-term over-discharge will reduce battery life by a factor of three. At the very least, when there is a low battery warning in the electric vehicle riding, stop the ride decisively and charge the lithium battery.

   2, the timeliness of charging: (1), lithium battery charging is effective at any time, even if there is 50% of electricity before charging, it does not matter, because it is different from nickel-metal hydride battery, the latter has memory effect Lithium battery does not. (2), do not overcharge, when the charging completion indicator is on, stop charging.

   3, make up the self-discharge charging: If you do not use the battery for a long time, you must charge it once in 60~90 days, because the optimal storage state of the lithium battery is semi-electric storage (that is, 40%~60% of the nominal capacity of the battery) Between storage), we know that the maximum voltage of the lithium battery is 4.2V, therefore, the storage voltage is preferably between 3.8V and 3.9V, and the capacity is basically half.

   4, the original charging equipment: try to use the original lithium battery charger to charge, the original charger supporting performance, charging rate is moderate, there are some fast charging piles, it is recommended not to use more, use the last time, twice in a year There is no excuses. Excessive current charging also has a greater damage to the internal structure of the battery.

   5, the temperature environment during storage: Lithium battery temperature environment is wide, -20 ° C ~ 45 ° C, but in fact the most suitable temperature is room temperature. From the perspective of "aging", temperature may be the main reason for the gradual decline in lithium battery capacity. For countries with large temperature differences in China, the northern region should develop low-temperature lithium batteries, while the southern region should develop high-temperature lithium batteries.

   6. Strictly observe the precautions in the manual: When the lithium battery is idle, it should be placed in a cool and ventilated place to avoid high temperature and humidity. Try to avoid riding in rainy days, even if riding, be careful to prevent the lithium battery from entering the water.
