From the market, the current selling of electric vehicles, whether it is battery brands, styles or brands are diverse, and lead-acid batteries and lithium iron phosphate batteries, then what is the difference between lithium batteries and lead-acid batteries? The following points are the differences between the lithium battery and the lead-acid battery summarized by the Crown Lida battery, and it is hoped that it can provide a reference for consumers.
details as follows:
· Quality and volume
Usually, the lead-acid battery pack weighs 16-30 kg and has a large volume. The lithium battery generally weighs 2.5-3.0 kg and has a relatively small volume, so it is easy to ride and easy to carry. From the quality point of view, the quality of the two is difficult to define, but consumers can buy a good quality battery produced by a regular manufacturer according to their actual needs.
· Battery capacity
The capacity of a lithium battery is generally 8-10 amps; the capacity of a lead acid battery is about 20 amps.
· Driving kilometers
For example, the same 48V battery, in the case of full charge, lithium batteries and lead-acid battery electric cars can exercise 30-40 km, the speed is mainly depends on the size of the motor used.
Lithium batteries are more durable, consume less, charge and discharge more than 500 times, and have no memory. The general life expectancy is 4-5 years. Lead-acid batteries generally have a deep charge and deep discharge of less than 400 times, and have a memory life of about two years. If you are using a maintenance-free lead-acid battery, you need to be aware that the battery has less water loss, and you do not need to add distilled water during use. In terms of durability, the lithium battery has good vibration resistance, and the battery in a fully charged state is safely fixed, vibrating for 1 hour with an amplitude of 4 mm, a frequency of 16.7 Hz, no leakage, no battery expansion and rupture, and an open circuit voltage is normal; Good chargeability, 25 degrees Celsius, fully charged battery 0.1CA charge for 48 hours, no leakage, no battery expansion and rupture, open circuit voltage is normal, capacity retention rate is above 95%; high current resistance, fully charged state The battery 2CA is discharged for 5 minutes or 10CA for 5 seconds, and no conductive portion is blown, and there is no appearance deformation.
