4.4.2. Connect Temperature Cable
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.
The Temperature cable provides 10 kΩ NTC thermistors for temperature measurement of the cells
and/or surrounding area. These sensors are used by Nuvation Energy BMS to detect over and under
temperature conditions and adjust battery current limits to compensate for cell temperature.
2 to 7 thermistors are supported to accommodate systems requiring Nuvation
Energy BMS to meet functional safety requirements.
Cable Isolation
Because the sensors are referenced to the CELL0 or BLOCK0 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, as well as any metal work or
other exposed conductors, in such a way that they will not make an electrical connection to a cell
terminal in the event of vibration/failures.
