4, 8 SI+B,
SI-B Differentially Return–Signal to CON module or to previous ANA-
module (ca. 10kHz)
ANA module, 8 pole connection Top – communication to the next module
Pin Signal Description
1, 5 T1, T2 Differentially ISO SPI signal to the next ANA – module
2, 6 Shield
3, 7 EN+T,
EN-T Differentially stimulation signal to the next ANA module (ca.
10kHz)
4, 8 SI+T,
SI-T Differentially Return signal from next ANA module (ca. 10kHz)
The single cell voltages are connected to 14 pole connector. The wire gauge should be 0.5
mm².
For the Temperature Measurement in the battery are connected 5 sensors to the SL6 ANA
module. The sensors 1…3 are used for the accurate temperature measure in the battery.
The sensors 4, 5 are used for the second level Hardware detection (Over and under
Temperature). The sensors are connected to the 10 pole connector.
Sensor Types:
- Sensor 2 … 5: VISHAY NTCLE100E3103 with 10 kΩ resistor at 25 °C
Or types with similar temperature characteristic
Second Level detection:
-
Sensor 4 triggers an Under temperature signal at lower than -40 °C,
- Sensor 5 triggers an Over temperature signal at higher than +90 °C
3.6.8.2 C
ONNECT LESS THAN
12
CELLS
To connect less than 12 cells, the not presented cells must be replaced by shorting to the
connector. The allowed voltage range of the Slave6 A module is describe in chapter
3.6.8.6.
The crimp contacts are not able to use more than 1 wire in one contact; short circuit
connection should be realized outside of the connector. The short circuit wires must be
short as possible, e.g. with isolated shrink hose solder connections.
