ADVANTAGES

MODULARITY
The standardized & scalable design of the KBM module enables quick and easy connection in both serial and parallel configurations. It can be configured into systems of 2kWh up to a scale of MWh.
MAINTENANCE
Each module is built as an independent tray which facilitates effective and sufficient handling when maintenance is required.
AIR VENTILATION
Cells within the modules are maintained at optimal temperatures to enable a longer life cycle. Optional heat sink plates can be provided to cool electronic components and increase thermal capabilities.
CUSTOMIZABLE TO MEET NEEDS OF THE CUSTOMER
Kokams Battery Modules are designed to accommodate cells with different capacities and can easily be tailored to meet diverse energy, voltage, and power requirements. In addition, Kokam Battery Module safety features, implemented using various thermal management mechanisms and Battery Management Systems (BMS), give our customers a high level of confidence during operation. Each module contains a dedicated and integrated BMS (Battery Management System) that efficiently monitors the voltage and temperature of each individual cell and equalizes the voltage of the cells through its balancing mechanism.
