Advantages of LiFePO4 Battery:

1.High safety performance. As a car power, safety is among the first thinking factors. Although the safety of general Lithium Batteries can be basically ensured, there is possibility of fire and explosion under the pole condition. LiFePO4 battery as the two generation products, its physical function is stable, no explosion no fire, is now the world’s only sure the safety of lithium ion battery.

2.Long life and low cost. As the power battery, its life is closely related to the overall cost. The battery can walk more than 500 thousand kilometers, and can use five years or so. Coupled with its production cost is lower than its general lithium battery, it can greatly decrease the cost of the use and protection of electric vehicles.

3.Use processing convenience. LiFePO4 Battery does not contain any heavy metals and rare metal, non-toxic, no pollution, in accordance with the regulations, it is green environmental protection battery.
 

4. Energy efficiency. 

--Self-discharge. All rechargeable batteries lose charge over time, but the rate with LFP is only 3-5% per month. NiCd loses 15% in the first 24 hours, then drops to 10-20% per month (depending on temperature). 

--Charging efficiency. During the charging process of any battery, energy is lost in the form of heat. the charging efficiency of LFP is very high, about 95%. 

 

Performance Curves of LiFePO4 Cell:
 

1. LiFePO4 Cell Charge Curve (Charge at 0.1C)
 

2. LiFePO4 Cell Discharge Curve (Discharge at 0.2C )

3. LiFePO4 Cell Charge Efficiency At Different Temperature

4. LiFePO4 Cell Cycle Life Curve

5. LiFePO4 Cell Capacity Change At Smart Floating Charge At 55 degree
