[two_thirds] Modular lithium battery pack - PowerModule - Lithium Iron Phosphate LifePo4 - by PowerTech Systems
PowerModule by PowerTech Systems

PowerModule batteries are advanced energy solutions for traction applications requiring high capacity and/or high voltage (up to 700 volts). The modules can be connected in series or parallel to increase capacity or voltage. Up to 255 modules can be assembled in series or parallel. Systems have two levels of security to ensure optimal level of operation : each module embeds a slave BMS and an external BMS is dedicated to module management.

Each 12V Lithium-ion module has a built-in BMS that monitors operating conditions (temperature, over voltage, under voltage, etc..). An external BMS ensures optimal operation by a real-time monitoring of each module (up to 255).

PowerModule® batteries embeds Lithium Iron Phosphate cylindrical cells (LiFePO4) that offers a high level of safety and long lifespan. PowerModule® solutions advantageously replace Lead acid solutions for many applications (Electric vehicles, off-grid or micro-grid systems, energy storage, etc.).

PowerModule® batteries are ideal solutions for advanced energy systems requiring high voltage or capacity. This lightweight, flexible and scalable system greatly simplify deployment and operation.
