3.5 THE HARDWARE OF SLAVE_5
The BMS SLAVE_5 is part of the modular Battery Monitoring System by ACTIA I+ME. With
one SLAVE_5-Modul from 5 … 10 single lithium cells may be controlled; up to 31 SLAVE_5-
Modules may be connected to one MASTER unit; the maximum amount of cells is 310.
SLAVE_5 and SLAVE_C are substantially identical with following differences:
- electronic board casted in a plastic case
- different connection technology; MicroFit crimp connectors instead of cage clamps
- Different temperature sensor system: NTC’s with 10 kΩ instead 30 kΩ @25°C
- separate piggyback balancing board with lower resistor values for higher balancing
currents
