3. High-Voltage Stack Controller

3.1. Overview

The High-Voltage Stack Controller module monitors and controls all Cell Interface modules in a single
battery stack. The built-in Stack Bus receives power and communication from the Power Interface
module. The Link Bus provides power and communication for all connected Cell Interface modules.
Ethernet, CAN and RS-485 (Modbus) are included. No high-voltage or high-current interfaces are
present on the Stack Controller, making this module easy and safe to connect to for service
operations.
There is only one model of the Stack Controller, the NUV100-SC.

3.2. Mechanical Dimensions

The overall dimensions of the Stack Controller are 104.4 mm X 121.58 mm X 40.6 mm.
It comes standard with DIN clips that enable the Stack Controller module to be securely mounted to
EN50022-compliant DIN rails. The clips add an extra 19.6 mm to the overall width of the Stack
Controller module, bringing it from 104.4 mm to 124 mm. The clips also hold the module
approximately 7 mm away from the inside lip of the DIN rail.
Extra space should be provided around the module to allow for easy installation/maintenance.
The Stack Controller weighs approximately 525 g.
