An electric vehicle performance, lead-acid batteries (including lead-acid gel batteries) single-seat twin electric tricycle, cost cheap, stable performance, the electric car on the market use of such batteries. 2, lithium-ion battery (often referred to as lithium batteries), expensive electric tricycle rankings, the performance is unstable, prone to explosion, the safety factor is low. Being developed using lithium iron phosphate battery solve the security problem. Being further improved. 3, crystal plastic battery, high cost, stable performance, the use of such batteries of electric vehicles on the market are rare, only a few merchants had to configure this high-performance battery, the highest safety factor. Life is much higher than the first two types of batteries superiority advantage and self-healing capabilities is the industry's leading position, the advantage is the lead-acid batteries do not have to avoid the disadvantages of lead-acid batteries stratification. Service life of the battery electric vehicle is a chemical substance, and thus also a certain service life, such as a dry battery (including ordinary alkaline batteries), and other primary battery is not charged, the service life of course only once. For rechargeable batteries, usually measured by the number of times we have to charge the length of their service life. Nickel-cadmium battery cycle life of about 300 to 700 times the number of Ni-MH rechargeable battery is generally 400 to 1000 times, lithium-ion battery is 500 to 800 times. The service life of the rechargeable battery cells not only by making use of raw materials, production process and other factors, electric tricycle, Ltd., also with the battery charge and discharge method and the actual usage closely. For example, someone in 1985 using six nickel-cadmium battery electric tricycle, always continue to use, but some of the battery capacity is reduced. It seems, as long as the use is reasonable, rechargeable batteries can be achieved even more dramatically than the nominal service life.
