Feature of LiFePO4 Battery
● Longer Cycle Life: Offers up to 10 times longer cycle life
and 5 times longer float/calendar life than lead acid battery.
Helping to minimize replacement cost and reduce total cost of
ownership.
● Lighter Weight: About 40% of the weight of a comparable
lead acid battery. A ”drop in” replacement for lead acid battery.
● Higher Power: Delivers twice power of lead acid battery,
even high discharge rate, while maintain high energy capacity.
● Wider Temperature Range: -20℃~60℃
● Superior Safety: Lithium iron phosphate chemistry
eliminates the risk of explosion or combustion due to high impact,
over charging or short circuit situation.
● No Memory Effect: Support unstable partial state of charge
(UPSOC) (charge/discharge) utilization.
Functions of BMS
● Over charge detection function
● Over discharge detection function
● Over current detection function
● Temperature protection function
● Short circuit detection function
● Balance function
Application
● Electrical vehicles
● Solar/wind energy storage system
● UPS, backup power
● Telecommunication
● Medical equipment
● Lighting…
