Storage Types; Configuration File - Nuvation Energy NUV300-BC-12 Product Manual

A negative value for Current represents a charge direction while a positive value
represents a discharge direction with respect to the cell/stack. Some Current
registers represent the magnitude of the current and are never negative in value.
These register exceptions include the following:
▪
stack_current_limit.min_charge_current
▪
stack_current_limit.max_charge_current

▪
stack_current_limit.max_discharge_current
▪
stack_charge_status.hold_current
▪
stack_control.precharge_max_current
▪
stack_control.precharge_bias_current
▪
stack_fault_precharge_over_current.thresh

7.1.3. Storage Types

Each register in Nuvation Energy BMS can be one of five storage types.
Volatile
▪
Data that is not persisted across a system reset
Configuration
▪
Data that is persisted on the
Persistent
▪
Data that is persisted and regularly saved
Factory
▪
Data that is persisted when requested and is typically set at the factory
Manufacturing
▪
Data that is persisted and saved at manufacturing time
These types of storage can be read directly from the Operator Interface Registers menu option as
discussed in Section 6.3.1.

7.1.4. Configuration File

Configuration is stored externally to Nuvation Energy BMS in a plain-text file. This file defines the
state of configuration registers as required for a particular system.
To generate a configuration file for a stack, visit the nCloud at: https://ncloud.nuvationenergy.com.
nCloud is the Nuvation Energy online portal.
The Operator Interface provides tools for importing and exporting configuration files to and from
Nuvation Energy BMS as a way to set or retrieve the state of all configuration registers.
