8.2.2. Temperature Sensors
The Temperature Sensors connector provides NTC thermistor inputs for temperature measurement of
the cells and/or surrounding area. Because the sensors are referenced to the
CELL0
(or
BLOCK0
on CI-
4M12) input on the Cell Interface, care must be taken to ensure that they are electrically isolated
from any common or ground potential, and from all other cell voltage terminals of all Cell Interface
modules in the system. The thermistors must be isolated from the cell voltage terminals in such a
way that they will not make an electrical connection to a cell terminal in the event of
vibration/failures.
Connect up to eight 10 kΩ NTC thermistors to this connector.
The Stack Switchgear is pre-configured to expect a defined number of thermistors
based on the information provided to Nuvation Energy during order fulfillment.
Failure to use the same number of thermistors will result in undesirable Stack
Switchgear behavior. Please contact
change requiring a Stack Switchgear configuration update.
2 to 7 thermistors are supported to accommodate systems requiring Nuvation
Energy BMS to meet functional safety requirements.
