Kokam Battery Module(KBM)
Liquid Cooled Battery
Kokam EV Battery Pack (XPAND)
NEW GENERATION EV BATTERY PACK
Kokam Battery System is designed for use in commercial truck, bus, tram, and heavy duty transportation. The system can be integrated in parallel and in series to create very high energy and high voltage systems. Furthermore, the “Variable Bulkhead” allows Kokam to customize the packs’ electrical and cooling interfaces without having to retool the entire systems.
EV Battery Type 1 : Xpand
- Easy to customize high voltage, low voltage and cooling interfaces to each application
- All connections at front panel; rear access not needed for installation
- New Kokam BMS permits very large strings and pack combinations (Up to 750V per string, and up to 24 strings in parallel)
- Allows upgrades to connector styles, fuses, VTBs without tooling entire pack
- Robust, highly serviceable BDU with integrated SCU; standalone MCU
- Available with or without internal fuse
- Highly robust tab-to-busbar joint survives the harshest vibration & shock environments while maintaining ultra-low DCIR
- Direct cooling to cell face; 50-75% less mass than competing technology; maximizes volumetric efficiency
- Enhanced cell separator eliminates the need for thermal barriers
