The high-level system design of G5 Stack Switchgear is shown in
G5 Stack Switchgear connects to the daisy-chained Nuvation Energy G5 Cell Interface modules. The
G5 Cell Interface modules convert cell voltage and temperature measurements to digital values to be
relayed to the G5 Stack Switchgear, and enable or disable cell balancing as required. Daisy-chaining
the G5 Cell Interface modules facilitates the design of flexible and scalable battery energy storage
systems.
The G5 Stack Switchgear has high-voltage, high-current connectors that are accessible on the front of
the unit. These connect the battery stack to the rest of the system, which is typically a common DC
bus. Safety precautions are required to handle and connect cables into this unit.
The external interfaces to this unit are:
▪
Battery Stack and DC Bus connectors
▪
Service Disconnect Switch
▪
10/100 Base-T Ethernet RJ45 jack (Modbus-TCP)
▪
Link Bus RJ45 connector
▪
Fan control input and output
▪
Power In
▪
Power LED and Fault LED
▪
Earth bonding connection (grounding stud)
