The lithium battery system consists of rack, modules, battery management system (BMS), screen-touch control and protection system. The BMS is placed inside the battery to monitor the status of every cell, so the location of the faulty cell will automatically be identified. In addition, relays, fuses, circuit breakers and BMS are used for the protection of the battery packs.

Application
  • To meet industrial and commercial demand management, peak shaving
  • To serve as backup power
  • To conduct peak shaving during high power demand periods and valley filling during off-peak hours
  • Power storage, peak and frequency regulation 
  • To build a microgrid system
System Topology
Features
Safe and Reliable
  • The battery has high quality LFP cell.
  • Designed with an intelligent air-cooling system to ensure long service life of battery with stable operation.
  • The Lithium battery features a built-in Battery Management System (or BMS) which ensures safety and long battery life by constantly monitoring battery performance, internal temperature, and other critical elements required in safely functioning battery.
  • Choosing a LiFEPO4 battery means lesser worries since it has a built-in protection system including a relay, fuse and circuit breaker against overcharging, undercharging, and short circuits.
Efficient and Convenient
  • A number of batteries can be paralleled to form a battery bank with maximum 1C charging and 2C discharging.
  • The battery is convenient for maintenance, management and capacity expansion.
Active equalization
  • Power is transferred in a more balanced way to reduce negative impact of single cell on battery capacity.
  • The equalization accuracy is less than 2%, and the equalization capacity can reach 10% of the rated output.
Lower Cost
  • Smaller size, lighter weight, less space and lower installation cost.
  • Long service life, low failure rate to reduce operation and maintenance cost.
