5.We use pouch cell to assemble battery pack
6.How we package
7.Advantages
1. Low internal resistance
Methods of reducing the internal resistance:
**Using carbon coated aluminum foil
**Multiple electrode tab design
**Increasing the width of electrode tab
**Coating PVDF on battery separator
**Pore-creating artificially
2.Long lifespan
Usable for more than 2,500 charge-discharge cycles
> 4 times than lead acid battery
> 2 times than li ion battery
3.Excellent performance in high and low temprature
Usable in extremely cold and hot environments (-20 to 60 ºC)
8.Application:
The largest lithium-ion battery production base for new energy vehicles.
LiFePO4 and NMC(Li(NiCoMn)O2) are the major material. We have more 30 types of cells, and could make OEM battery pack from 12V-200V, 10-200ah, which can be used in electric vehicle, E-bike, UPS, energy storage system, telecommunication base station, E-scooter, E-tools, unmanned airplane, golf cart, fork lift, cleaning car, electric wheelchair, etc.
10. CTS Customer Feeback
Do the batteries have a warranty?
§ Yes, currently 3 years; extended warranties are also available.
How long do the batteries last?
§ 10 years / 200,000 KM (124,275 miles) [calculated based on 100km battery pack]
§ 2000 charges & discharges at 100%.
§ This means approximately 10 years of normal use 200,000 KM. (124,275 miles)
§ Normal use is defined as 20,000km/year. (12,500 miles/year)
Do you use Lead Acid Batteries?
NO WE DO NOT! Our reasons:
§ Lead Acid Batteries do not allow as many charge & discharge cycles as advanced lithium batteries
§ Lead Acid batteries degrade after 300 charge cycles in an electric car until they expire, approximately 1.5 -2 years of driving
§ Not cost effective to change your battery pack every two years
§ Lead Acid is HEAVY, and reduces your range, doesn't supply continuous power
