Scalable and modular Lithium-Ion energy storage system PowerModule® : Modular, Smart, Safe and efficient energy storage solution. Modular Design Each PowerModule block is designed around a high performance 5.4 kWh Lithium Iron Phosphate (LiFePO4) battery composed of sealed cells. PowerModule Unit - Technical Specifications Weight (+/- 3 %) Operation temperature from -25°C, up to +65°C Amphenol Powerlok IP67 123.5 Wh/Kg Energy density Continuous discharge current (at 20 °C) Peak discharge current (10 minutes) Peak discharge current (30 s) Recommanded charge voltage The PowerModule blocks are connected to each other by a private and secure communication bus. This distributed architecture ensures high fault tolerance and easy commissioning. Specific energy Power connector Each module is equipped with BMS Matrix® technology, which ensures the complete safety of the battery in real time and drastically extends its lifespan. The BMS also manages a cell heating system for operation in temperatures down to -25°C. Floating charge voltage (optional) Standard charge Current Fast charge Current Technical features of BMS Matrix® Technology • Plug-and-Play” and flexible system : Easy and fast commissioning “ • calable system : Serial and/or Parallel assembly up to 128 modules to fullfill S • Monitoring of each PowerModule block : current, power, voltage, PCB tem- the most complex appplications • eal-time monitoring in the cloud is available R • Stainless steel housing with waterproof connection (IP67) • xternal communication by CAN bus available E • igh lifespan and number of cycles H • ertification : CE, UN 38.3 C perature, cell voltage and temperature, State of Charge (SOC), State of Health (SoH), Contactor states, etc... • Realtime communication of alerts, warning and status messages using bus CAN 2B for external devices. • Intra module balancing between each cell. This function is started as soon as a voltage difference >30mV is detected between 2 cells within the same module. • Inter module balancing is launched as soon a voltage difference > 100mV is detected between two or more PowerModule Further information at : www.powertechsystems.eu or contact our commercial office : • Automatic cut-off triggered by alert events, ie : over-current, over-charge, over-temperature, etc, or manuall triggered by CAN message • Cell heating system management • Industrical vehicles • Marine • UAV • Robotics
