State
Description
Ready
A stack is enabled, within operating limits, ready to be connected to the DC bus, and
has established communication with the Battery Control Panel
Connected
A stack is ready and electrically connected to the DC bus
The above states are integrated into all aspects of pack level functionality and are referenced
throughout the following sections.
8.3. Network Settings
The Ethernet IP addressing used by each stack in the pack must match the network configuration of
the Battery Control Panel.
The recommended network topology has each stack connected the Battery Control Panel’s internal
network ports (labeled
Local Ethernet
).
The Battery Control Panel internal network interface has the following settings by default:
▪
IP:
192.168.1.10
▪
Subnet:
255.255.255.0
▪
Gateway:
None
Each stack is assigned a static IP address on the Battery Control Panel internal
192.168.1.0/24
subnet.
The Battery Control Panel Ethernet bridges must be configured to match this IP address assignment.
There is one instance of the Ethernet bridge component for each stack in the pack.
Network settings can be viewed and modified either through the
in the Platform
Interface or via the Configuration Registers below.
gbc_eth_bridge[n].ip_address
▪
The IP address of stack
n
. This is set to the stack’s IP address.
gbc_eth_bridge[n].port
▪
The port of the stack
n
request bridge. This should be set to
8080
.
gbc_eth_bridge[n].publish_port
▪
The port of the stack
n
publish bridge. This should be set to
8081
.
8.4. Pack Topology
Battery pack topology configuration is required to specify which stacks are connected in each bank as
well as the number of banks within the pack. The following registers must be configured for each
stack in the pack (the
pack_stack
component instances correspond in order to the
gbc_eth_bridge
component instances).
