How to charge lithium-ion battery to prolong its service life? To prolong the life of lithium-ion batteries, we have to predict the reason. Several factors that affect the life of lithium-ion batteries: the number of charging cycles: from 0% to 100%, which is the number of charging cycles. This is basically related to the material and technology of the battery itself. No matter how you care about it, it cannot be changed.

How to charge lithium-ion battery to prolong its service life?

1. The lithium ion battery is effective at any time, even if there is 50% of the power before charging, it doesn't matter. This is because it is different from the nickel hydrogen battery, which has memory effect, but the lithium ion battery does not. However, it should be noted that lithium ion batteries cannot be over-discharged, which will cause irreversible capacity loss. When the machine reminds that the battery is low, it should start charging immediately.

2. Never overcharge. When the charging completion indicator is on, stop charging. If the battery is not used for a long time, take it out of the instrument and store it in a dry and cool place, and charge it once within 60~90 days to avoid too long storage time. The battery will be too low due to self-discharge, resulting in irreversible capacity loss, because the best storage state of lithium ion battery is semi-electric storage.

3. Use the original charger. Try to use the original lithium-ion battery charger for charging. The original charger has strong supporting performance and moderate charging rate. At present, there are some fast charging piles. It is suggested that we should not use more. It is understandable to use them once or twice in a year. Excessive current charging also causes great damage to the internal structure of the battery.

4. Temperature environment for storage. The temperature environment is wide, ranging from - 20 ℃ to 55 ℃, 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 ion battery capacity.

5. Strictly follow the precautions in the manual. When the lithium-ion battery is idle, it should be placed in a cool and ventilated place to prevent high, gentle and humid. Try to avoid riding in rainy days. Even when riding, it should be well protected to prevent the lithium-ion battery from entering water. Do not knock, prick, step on, refit, sun the battery, and do not place the battery in microwave, high-voltage and other environments.

Precautions for lithium ion battery charging

1. Moderate charge

Keeping the lithium ion battery properly charged and discharged can prolong the battery life. Maintaining the charge of lithium-ion battery at 10%~90% is beneficial to protect the battery. When charging the battery of mobile phones, laptops and other digital products, it is not necessary to reach the maximum value.

2. Select appropriate charging temperature

Lithium ion battery charging temperature range: 0~45 ℃, lithium ion battery discharge temperature range: 0~60 ℃.

3. Prevent overshoot

During the charging process of lithium-ion batteries, it is necessary to prevent the initiation of overcharge. Any form of overcharge of lithium-ion batteries will cause serious damage to the battery performance, even explosion.

4. The first charge is not activated, standard charging time

The charging and discharging characteristics of lithium-ion batteries and nickel batteries are very different. Do not charge them for more than 12 hours. Repeat for three times, and charge them according to the standard time and standard method. In particular, do not charge them for more than 12 hours.

In fact, lithium-ion batteries are not afraid of charging, but are afraid of losing power? Many batteries have so-called "charge management IC", so that the battery will not explode beyond the safe voltage when charging, and will not be too low to start the charging procedure because of no power. Therefore, if the lithium-ion battery has no power and is not recharged after being placed for a long time, it is likely that the battery will be scrapped early due to the low voltage. If lithium ion batteries are not used for a long time, it is better to retain 40% of the power.

How to charge to prolong the service life of lithium-ion batteries for electric bicycles?

The charging time of the electric bicycle should be controlled within 10 hours. It is easy to damage the battery if the charging time is too long. Every time you charge the battery, you should charge it before it is used up, so that the damage to the battery is relatively small and the service life is relatively long. The key to the service life of the electric bicycle is the reasonable use and maintenance of the lithium-ion battery.

Many electric bicycles have a short service life, which is mainly due to the improper use of lithium-ion batteries. The charging time should be reasonably controlled according to the mileage traveled. The charging time at a time should not be too long.

At present, the warranty period of most lithium-ion batteries for electric bicycles on the market is one year, and the battery can be recharged from 250 to 300 times. In terms of maintenance, the following suggestions are given: when starting a bicycle, do not rely solely on electric starting, but cooperate with pedal assistance; In addition, even if it is not used for a long time, the battery should be recharged once a half month. This will extend the battery life. In addition, the tire should be fully inflated, and the switch should be closed in time when getting off.

The lithium-ion battery has no memory effect. Don't wait until the battery is used up, or even turned off, to remember to charge it, so as to prolong the cycle life of the battery.
