****Types of electric bicycle batteries:
Batteries are the power source of electric bicycles, and battery quality directly affects driving range and life.
Life. The batteries currently used for electric bicycles are divided into lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries.
① Lead-acid battery: The full name is sealed maintenance-free lead-acid battery, which is cheaper, large in capacity, and relatively mature in technology
, Especially the battery manufacturers through reforming the process, optimizing the formula, and improving the charging technology, so that the battery performance
A new breakthrough, the service life of the battery has been greatly improved. The 36V12Ah battery weighs 12.6 kg and has a driving range on one charge.
Up to 70 kilometers (according to the testing conditions), the average battery life is more than one year, and it costs 400 to change the battery once
Around yuan. The fly in the ointment is that the battery is still too heavy. Lead-acid batteries have become the main driving force for electric bicycles
②Nickel-cadmium battery: light weight and long life. Commonly used is 24V5Ah battery, weighing 3.2 kg, driving range on one charge
It is 16 kilometers. According to the standard, 80% charge and discharge, lifespan is about 500 times. But the price is higher, the capacity is lower, and the driving range
Short, and the battery has a memory effect, the battery can be charged only when the battery is discharged. At present, it is rarely used in China.
③Ni-MH battery: The commonly used battery is 24VAh, which has higher specific energy than Ni-Cd battery and can travel 23 kilometers on a single charge.
It overcomes the shortcomings of nickel-cadmium batteries, has no memory effect, and has recently fallen in price with increasing production. Currently
Used on some electric bicycles.
