wCMB –
WIRELESS CELL MONITORING BOARD
ME offers a wireless cell monitoring board (wCMB). This product allows the integrator to get rid off all communication harnesses within the battery pack. Maximum flexibility and re-usability of modules can be achieved with this technology. Immersion cooled battery packs benefit from the wireless communication in particular, as sealed cable interfaces are removed.
THE HIGHLIGHTS:
High cell voltage measurement accuracy
Functional Safety and Security certified wireless communication technology
Weight and cost savings on pack level due to reduced wiring and connectors
Increased reliability due to reduced number of interconnects
wCMB can be integrated with the SBS
