Board connected

To start evaluating board parameters and its configuration, the user must first connect the

board to a USB port using the USB micro-B cable and then connect the GUI using the

connect tab. When the board is connected properly to the GUI, it shows the message “The

board is connected”, as shown in Figure 34.

Key battery parameters

The following are the parameters that appear on the first page (key parameter page) of the

GUI, as shown in Figure 35.

●

Board hardware: it is possible to read and write the value of the sense resistor as well

as the room temperature value.

●

Alarm: it is possible to R/W the battery low voltage alarm as well as the low SOC alarm.

●

Battery parameters: it is possible to read and write total battery capacity, internal

resistance of the battery pack as well as the open circuit voltage and its relative SOC

percentage table to be used for an estimation of initial SOC of battery depending on the

open circuit voltage.

●

Control register: it is possible to read the value of the control register as well as write

the 1st bit (bit 0) of this register.

●

Mode register: it is possible to read the value of the mode register as well as write the

3rd and 4th bits (bit 2 and 3).
