SECTION 2 - SERVICE PROCEDURE
There are 6 temperature sensors on 48V, 11 on 72V and 13
on 83V. The temperature sensors are put on the cells to
monitor the temperature.
The temperature sensors are also supplied with internal
switches that disable the sensor if any parameters are out
of range. In such case the value shown will be "0". If
required, the BMS activates two fan to cool down the tem-
perature inside the pack. Refer Section 1.
2-16
72 Volts battery pack (Valid for 2nd Gen only)
If everything is ok, the BMS feeds the coil of the internal
contactor (relay), so the current can go outside the battery
pack. In case of failure or incorrect parameters, the BMS
keeps the internal contactor open and the current cannot
reach the inverter.
2nd Generation system cells and temperature sensor
arrangement are shown in above figure.
