Charging time is 6 to 8 hours. If the discharge is deep, for example if the battery is exhausted, the charging time will be very long, up to 10 to 15 hours. It is best not to use lead acid batteries. Lack of electricity, otherwise the service life will be shortened. The charge must be sufficient. It is suggested to charge for 2 hours after changing the light. However, charging should never exceed 12 hours.
The following points should be considered when charging electric vehicles:
p>
1. Do not recharge the battery once it is empty. If you recharge it after it is empty, the battery capacity will decrease by 2%. If it suits you, you can recharge when 70% is used. It is not recommended to charge gradually
3: The charge must be sufficient for 2 hours after switching on. However, recharging is strictly prohibited. Don't go beyondnot enough 12 hours.
4: During normal charging, the actual charging time can be determined based on the amount of electricity used. used for charging in the future and the charging time is too long, the power should be cut off in time and sent to the hospital. Check the battery and charger to prevent the battery from being overcharged. If it is not used for a long time, it is best to charge it once every 20 days. Do not store it at low voltage
6: Do not do it casually If you use someone else's charger. To charge, if the voltage and positive and negative poles of the interface are different, it will damage the battery.
The low temperature performance of lithium batteries of different materials is also different. The most popular lithium iron phosphate now has the worst low temperature performance. The discharge capacity at-10℃ is 89% of maximum. capacity, which should be the best in the industry. Relatively high; the release capacity can reach 95% at 55°C, and the attenuation at relatively low temperatures is relatively small. This is still a product sent for inspection. As you know, the quality is much higher than normal products on the assembly line.
Relatively speaking, the low temperature performance of lithium manganate, lithium cobalt oxide and ternary products is better, but it is also limited at the expense of high temperature performance; Nowadays, lithium iron phosphate blown in industry has high safety performance and good high temperature performance. In fact, the battery activity is not as high as the above three, so it is relatively safer. Overall performance is still not as good asthose of lithium or ternary manganese.
Due to the low temperature of lithium batteries in winter, the lithium ions nestled on the negative electrode will produce ion crystals and directly pierce the separator. Under normal circumstances, it will cause a micro-short circuit and affect the separator. lifespan and performance, and can explode in severe cases!
Conclusion: Low temperature charging and preheating technology can end the above problems.
