I+ME ACTIA BMS Master 4 - Schematic for Slave 6

Hardware Manual
BMS Master 4 / 4.5
Ref.: IR14417 A 15.01.2018 Page 12/76
The slave module is internally supplied by three cells of the controlled battery, in 10 cell-
systems the cells number 6 to 8 (counting from minus pole to plus pole) are used. If less
cells are used, the slave module is supplied by the cells connected to the according cell
contacts.
2.4 SCHEMATIC FOR SLAVE 6
The Slave 6 is on the Master connector CN104 (Current) together with the Current sensor
connected. The Second Level Security is on connector CN106 (Slave Comm) wired.
The slave module can be connected to 4 up to 12 cells and covers the following functions:
 Communicating with the Master module
 Measuring of the single cell voltages
 Compensation of different cell charge states
 Measuring of temperatures
 Over and under voltage detection, (second level security)
 Over and under temperature detection, (second level security)
 Error events, notify the MASTER to turn of the relay
 Self-monitoring (cell voltage open wire check, balance check)
The ANA module is internally supplied from the connected cells.
The CON module is supplied from the MASTER.
