A Summary Of The Advantages Of Electric Bicycle Lithium Batteries
1. lithium battery is light weight and small volume
Li battery electric vehicle has a variety of brands at present. It is similar to lead-acid battery (simple electric bicycle) in power performance. It can be charged for 6~8 hours and can run 30~45 kilometers according to the capacity of the battery. The weight is only 1/5 of lead acid battery. At present, the current lithium battery is guaranteed for 2 years, and the lead-acid battery is guaranteed for 1 years.
2. lithium batteries have no activation characteristics
Lithium batteries are easy to activate. As long as 3-5 normal charging and discharging cycles can activate the battery and restore the normal capacity. Because of the characteristics of lithium battery, it has almost no memory effect. Therefore, there is no need for special methods and devices in the activation process of new lithium batteries.
3. Memory effect of lithium battery
In the lead acid battery, when the nickel battery is charged, it is always worried about the memory effect of the battery, and the electric bicycle lithium battery does not take the memory effect. It can be rechargeable without worrying about the charging power of the battery before the battery.
4. lithium battery has long cycle life
Lithium ion batteries charge and discharge at 1C rate. The cycle life of lithium ion batteries is greater than or equal to 500 times, and the capacitance of 500th times is larger than that of nominal Tongliang 70%. Even if the lead-acid battery is charged at 0.5 discharge and charged at 0.15C, its cycle life is less than 350 times, and the capacitance is less than or equal to 60%.
5. wide range of working temperature
The electric bicycle lithium ion battery works within a range of -25 degrees to 55 degrees, with a capacity of up to 70% of the nominal capacity, while the lead-acid battery works only within the range of 10 to 40 degrees and is not working normally at -25 degrees.
6. lithium battery charging time is short, green environmental protection
Because electric bicycle lithium ion battery has the characteristics of high current charging, charging time is only 4-5 hours, and lead-acid batteries need 8 to 10 hours. No heavy metal lead harmful to the environment is a product of high environmental protection.
