2. System Overview
The Nuvation Energy Stack Switchgear, shown in Figure 1 , is a pre-configured assembly that
incorporates the major functions of Nuvation Energy battery management system into a rack-
mountable unit which includes stack monitoring, electrical disconnects, pre-charging, current sensing,
fuses, and a safety relay for E-Stop. It also includes supporting components like power supplies,
indicator LEDs, and external-facing connectors.

The high-level Stack Switchgear system design is shown in Figure 2 . Within a battery stack, the Stack
Switchgear connects to the daisy-chained Nuvation Energy Cell Interface modules. The Cell Interface
modules convert cell voltage and temperature measurements to digital values to be relayed to the
Stack Switchgear, and enable or disable cell balancing as required. Daisy-chaining the Cell Interface
modules facilitates the design of flexible and scalable battery energy storage systems.
