3.2. Features
3.2.1. Main Functions
Manages multiple stacks
Manage up to 36 stacks.
Provides Unified View of Entire Battery
Access diagnostics and performance data of entire multi-stack battery from a single unified user
interface.
Provides Remote Access
Remote access for data analytics or for viewing and adjusting battery operation remotely via web
browser on a PC, tablet computer, or even on a smartphone.
Automates System-Wide Fault Response
Manually or automatically identify and act upon faults anywhere in the battery pack.
Communications
Communicate securely over Ethernet. Provides unified interface for site controllers to multiple
stacks.
Automatic Pack Connection
Allows the BMS to manage the connected state of all battery stacks within the pack. When
requested, the Multi-Stack Controller will connect all stacks if they do not violate the pack
connection voltage limit. Stacks are automatically connected when the limit is no longer violated
(i.e. when the stack voltage becomes close enough to the pack voltage that is safe to connect).
Maximize Pack Uptime and Connection
Provides a flexible configuration to manage battery stack faults at a pack level. A Nuvation Energy
support technician can configure a battery pack to tolerate a specified number of stacks that fault
and disconnect from the DC bus. The Multi-Stack Controller allows the pack to remain operational
and manage the reduced power capacity of the battery.
3.2.2. Unified View Operator Interface
A Browser user interface, which supports Chrome and Firefox, provides a view of:
Statistics View
Monitor pack-level statistics for voltage, temperature, and current across all cells.
Real-Time View
Monitor measurement and control information in real-time.
Aggregate State-of-Charge
View State-of-Charge calculated values for the entire battery.
