Characters of Hipower LiFePO4 batteries used in High Speed EV
High speed pure electric vehicles require high power discharge and regen pulses, with very long cycle life. In order for traditional batteries to meet these demanding requirements, they must be oversized to protect battery life. However, oversizing, by definition, implies a larger than optimal battery. Hipower shows low power loss with usage, allowing for a smaller battery that still meets end-of-life power.
 
Adoption of High speed pure electric vehicles, while on the rise, has been somewhat limited due to the extra cost associated with these vehicles. Hipower produces millions of cells a year, which allows us top leverage large-scale manufacturing techniques to reduce costs in high speed pure electric vehicle cell designs. Large volume production enables Hipower to offer excellent Price-Performance. 
 
Extremely long cycle life. Hipower LiFePO4 battery will keep above 80% of its original capacity after 2000 times cycles.
 
Deep charge cycle, High speed pure electric vehicles operate in a charge depleting model, which requires deep discharge of the battery over time. Hipower lifepo4 cells offers thousands of full depth of discharge cycles, the mode of operation expected for these vehicle uses. While offering high energy for greater charge depleting range, the hipower LiFePO4cells retain high power.
 
Hipower LiFePO4 cells¡¯ chemistry provides the foundation for a more highly abuse tolerant lithium ion solution in high speed pure electric vehicles application. In addition, cell and system design play crucial roles in overall abuse tolerance.
 
Hipower LiFePO4 battery is Light in weight and small in size. Hipower LiFePO4 battery is only 1/3 in weight and 2/3 in size of same voltage and capacity Lead Acid battery.
 
Hipower LiFePO4 battery is an absolutely environmentally friendly battery, non-pollution, excludes any rare metals and heavy metals, and it is approved by RoHS. None pollution both on producing and using.

LIFE CYCLE CURVE

A)
Under 80% DOD (depth of discharge) condition, our battery lifecycle would be up to 2000 times
After 1000 times life cycle (80% DOD condition), the capacity of our battery still hold 95%

B)

Capacity remains at 90% after 500 times discharge-recharge tests under 100% DOD condition.

 


3C10V over charge Curve

  

Large current (10c) discharge curve

¡ìNo effect to battery performance when getting back to normal recharge mode after complete discharge under 10C discharge current.

 



Large current (1C /2C /3C /4C /5C) discharge curve





Quick charge curve

¡ìBattery peformance can be recovered when getting back to normal recharge model after recharge under 5C condition, No leak, no damage of battery.
