3.2.6. Nuvation Energy Multi-Stack Controller
At the core of the Battery Control Panel is the Nuvation Energy Multi-Stack Controller which is
responsible for the management of multiple battery stacks via their Stack Switchgear units. It is the
central computing component inside the Battery Control Panel. It aggregates all the battery stacks in
the energy storage system and manages them as a single battery. Key features include:
▪
Sequencing the connection and disconnection of stacks during bring up and operation
▪
Providing battery data to energy management and environmental control systems
▪
Reporting system faults and warnings
▪
Making BMS configuration updates
Users can remotely access the Multi-Stack Controller to perform system changes or to observe
battery performance at the system, stack, and cell level. Users can also view aggregate or granular
voltage, current, temperature, and State-of-Charge data in real-time.
The Multi-Stack Controller includes internal storage for battery performance data logs. These data
logs may be used to:
▪
Support warranty claims by comparing actual and predicted battery degradation curves, based on
time and throughput
▪
Understand how different energy storage applications impact battery life
▪
Track down the cause and location of a performance issue
3.2.7. LCD Touchscreen
A 10.1" LCD touchscreen display on the front of the unit provides an at-a-glace view of the battery
system as well as provides access to the Nuvation Energy BMS Operator Interface, making it possible
to access performance data and user controls directly at the Battery Control Panel.
