US based manufacturer International Battery, which develops large-format lithium-ion rechargeable cells, modules and packs, is introducing a three class system for standardising modules – nested, slim and wide.
The modules incorporate eight large format International Battery cells connected in series and each cell has a unique recognisable battery management system board. They can be connected in series or parallel configurations and meet the desired voltage and energy requirements. The system will accommodate 30 modules for a maximum voltage of 760V and can use any of the company’s cells ranging from 40-200Ah capacity.
The cells provide information to a controller through a systems control board. The battery management system has sufficient intelligence to then determine any safety or operational non-conformance and provide reliable implementation of a latchable interlock system.
Currently, the company offers six cell models in two chemistries: 154Wh/kg and 278Wh/litre in the 740Wh 200Ah lithium nickel cobalt manganese cell (NCM with graphite anode); or 107Wh/kg and 192Wh/litre in the 512Wh 160 Ah lithium iron phosphate cell (LFP with graphite anode).
The company is focused on developing its manufacturing processes rather than chemistries and is the only US manufacturer with a solvent-free, water-based process according to its director of engineering Tony Reis.
