Different from the lead-acid battery, how to maintain a lithium battery?

With the vigorous promotion of new energy and the continuous advancement of electric vehicle battery technology, some high-performance battery "lithium batteries" gradually enter life. As the power source of the electric vehicle, the lithium battery is deeply affected by consumers with the advantages of high weight, durability, and the number of cycles. After all, the lithium battery and lead-acid batteries are different.

The use method is also different, how to properly use lithium batteries to affect the heart of consumers. Today, Xiaobian will come to some precautions for the lithium batteries of the Copcott: 1 Charges: (1), the battery is usually charged half-electricity. For the first time, it is best to fully charge the battery.

(2) When you ride, don't exhaust the battery, because the over-discharge is very harmful to the lithium battery. Long-term overlap will reduce battery life 3 times. At least, when the electric vehicle riding is too low, it is necessary to stop cycling, charge the lithium battery.

Picture 2 Charging timeliness: (1) Lithium battery is not. (2), must not overcharge, when charging the indicator light, stop charging. 3 Make up the self-discharge charging: If there is no battery for a long time, it must be charged within 60 ~ 90 days, because the optimal storage state of the lithium battery is half-electric storage (ie between 40% to 60% of the battery nominal capacity) Store), we know that the highest voltage of the lithium battery is 4.

2V, so the storage voltage is preferably between 3.8V ~ 3.3.

9V, and the capacity is basically half. Image 4 Original Charging Equipment: Try to use the original lithium battery charger to charge (do not directly use the lead-acid battery charger), charge the battery using a regular matching lithium battery charger, do not use inferior or other type of battery charger to give Lithium battery charging. The charger current has passed the lithium battery protection system, causing short circuit, causing the safety accident of lithium batteries.

The charger voltage is too low, so that the charging efficiency is low, it costs too much time. Image 5 When the temperature environment is stored: the temperature environment of the polymer battery is wider, is -20 ¡ã C ~ 45 ¡ã C, but in fact, the most suitable temperature is room temperature. From the perspective of "aging", the temperature may be the main reason for the gradual recession of lithium battery capacity.

For the country where the temperature difference in China is large, it is necessary to develop low-temperature lithium batteries, and the southern region should develop high temperature lithium battery. Picture 6 Strictly abide by the instructions: When the lithium battery is idle, it is necessary to place in a cool and ventilated place, avoid high temperature and moisture, rainy day to avoid riding, even if riding is also protected, cautious to prevent lithium batteries. Electric cars are a tool for our lives, do not let unprofessional knowledge and non-professional charging methods bring us unnecessary trouble, and hope that the majority of electric vehicles can use lithium batteries correctly and scientifically.
