3.6 THE HARDWARE OF SLAVE 6
Slave 6 is a part of the modular Battery Management System of ACTIA I+ME. The Slave 6
hardware consists of 3 different modules.
 1x SL6_CON module (control module) communication interface to the Master and
to the SL6_ANA modules
 Up to 32 SL6_ANA modules (analog module) monitoring 4…12 cells
 Up to 32 SL6_BAL modules (resistor modules) for passive cell balancing. The
balance modules are connected to the SL6_ANA modules
 The maximum number of cells is 384
The SL6_ANA module is powered by the connected cells. The minimum supply voltage is
10V.
3.6.1. FUNCTIONAL OVERVIEW SL6_CON
The SL6_CON module covers following functions:
 Communication with a BMS Master via CAN
 Isolated communication with SL6_ANA modules
 Transmission of the hardware monitoring status (second level detection)
 Isolated stimulation of the hardware monitoring (second level detection)
 Check the status of the hardware monitoring (second level detection)
3.6.2. FUNCTIONAL OVERVIEW SL6_ANA
The SL6_ANA module covers following functions:
 Measuring single cell voltages
 Control the passive cell balancing
 Measuring the temperature
 Detection of over and under voltage (second level detection)
 Detection of over and under temperature (second level detection)
 Isolated communication to other SL6_ANA and SL6_CON modules
3.6.3. FUNCTION OVERVIEW SL6_BAL
The SL6_BAL module is connected with the SL6_ANA module. Balance modules consist of
resistors for the passive balancing of cells. It is possible to adapt the value of the balance
resistors with respect to the cell type.
