Many consumers to sell electric car battery where to see the battery brand, model, style too much, do not know which battery to use? Do not know what is the difference between lead-acid batteries and Lithium Battery, the following for everyone to sum up a few lithium Battery and lead-acid battery difference, hoping to provide a reference for consumers:
Durability: lead-acid batteries generally deep deep discharge within 400 times, life expectancy in about two years. If you are using a maintenance-free lead-acid batteries, it should be noted that the battery water loss is small, the use of general do not need to add distilled water. Lithium battery durability is strong, slow consumption, charge more than 500 times, the general life of 4-5 years.
Volume, quality: the general weight of lead-acid battery pack is 16-30 kg, larger; Lithium Battery are generally 2.5-3 kg, the volume is relatively small, so riding light, easy handling. In terms of quality, both good and bad is difficult to define, consumers can according to their own needs, the purchase of regular manufacturers to produce good quality brand batteries.
Price, warranty period: the current market is the mainstream battery is 48 volts, if replaced, then lead-acid battery 450 yuan, the warranty period of 1 year; lithium battery prices are relatively expensive, need 1,000 yuan, but the warranty period of two years The
Driving kilometers: the same is 48V battery, in the case of full power, lead-acid batteries and lithium battery electric cars can travel 30-40 km. The speed depends primarily on the size of the motor used.
Battery capacity: lead-acid battery capacity of about 20 amps; lithium battery capacity of 8-10 An.
Lithium battery advantages
A. High energy density
Lithium-ion battery weight is the same capacity of nickel-cadmium or nickel-metal hydride batteries half of the volume of nickel cadmium is 40-50%, 20-30% of nickel hydrogen.
B. High voltage
A lithium-ion battery cell operating voltage of 3.7V (average), the equivalent of three series of nickel-cadmium or nickel-metal hydride batteries.
C. No pollution
Lithium-ion batteries do not contain harmful metals such as cadmium, lead, mercury and the like.
D. does not contain metal lithium
Lithium-ion batteries do not contain metal lithium, and thus not subject to aircraft transport on the ban on the carrying of Lithium Battery in the passenger and other restrictions.
E. High cycle life
Under normal conditions, lithium-ion battery charge and discharge cycle can be more than 500 times.
F. No memory effect
Memory effect refers to the nickel-cadmium battery in the charge and discharge cycle, the battery capacity to reduce the phenomenon. Lithium-ion battery does not exist this effect.
G. Fast charge
A constant current, constant voltage charger with a rated voltage of 4.2V allows the lithium ion battery to be fully charged for one to two hours.
