4. Nuvation Energy Cell Interface
4.1. Overview
The Nuvation Energy Cell Interface connects to the battery cells and temperature sensors. The Cell
Interface monitors and balances the cells, sends cell data to the Stack Controller, and prevents
overheating or overcharging of cells.
There are three models of the Cell Interface.
▪
The NUV100-CI-12-1, Cell Interface - 12 channel can monitor up to 12 series-connected cells
▪
The NUV100-CI-16-1, Cell Interface - 16 channel can monitor up to 16 series-connected cells
▪
The NUV100-CI-4M12-1, Cell Interface - 12V 4 channel can monitor up to 4 series-connected 12V
lead-acid cells
4.2. Mechanical Dimensions
4.3. Mechanical Overview
The overall dimensions of the Cell Interface are 104.4 mm X 121.58 mm X 40.6 mm.
The Cell Interface is available in a bulkhead-mountable enclosure as shown in
has five metal walls, leaving the bottom of the unit fully exposed. It must be mounted to a metal
bulkhead panel such that the panel covers the exposed bottom side.
The NUV100-CI-12-1 and NUV100-CI-16-1 variants produce up to 24 W and 32 W, respectively,
during cell balancing. A portion of this heat is transferred to the bulkhead.
Extra space should be provided around the module to allow for easy installation/maintenance.
The standard Cell Interface, Bulkhead weighs approximately 450 g.
The Cell Interface contains high-voltage signals reaching as high as 1250 V DC. Care
must be taken when mounting the PCB into a metal enclosure to ensure that the
metal walls remain a safe distance from the exposed conductor on the PCB.
Using 1250 V DC as an example, the metal walls of the enclosure must be at least
4.2 mm from the nearest exposed conductor and must not touch the PCB or any
component on the PCB, including the connector housings.
