Meters screen
This screen reports the basic status of the BMS through 3 analog meters, a digital meter and 6 indicators, in very simple terms, in order not to overwhelm the unsophisticated user.

Meters screen
Status screen anchor
This screen displays the entire present status of the BMS.
The status items are grouped into:
BMS: state of the BMS itself: power, time, current sensors, outputs
PACK: state of the pack: SOC, voltage, current
ELLS: state of banks and cells: voltages, temperatures, resisatnces, balance, communication
Graph screen anchor
This screen graphs the status of the BMS.
Plot of certain parameters over time Histogram of the present value of certain parameters
The parameters are shown are selectable.
Configure screens
There are 10 screens under the Configuration tab and they are:
Basic - This screen has buttons for cell chemistry and a box to enter the cell amp hour rating
Cell-V - This screen is for entering the information for SOC VS Voltage
Cell-R - This screen is for entering the information for Cell Resistance VS SOC and Cell Resistance VS Temperature
Battery - This screen is for entering the capacity of the battery and if there are strings in parallel
Measure - This screen has the following:
Button for Relearn - to have the BMS relearn how many cell boards there are
Cell Board indicators for total cell boards
Cell boards/bank - lists the number of cell boards configured and number of cell boards seen
Current Sensors - This is used to set-up both the Source and Load current sensors
Selector for pack voltage to come from the HVFE if the HVFE is present
Measurement section - to select if IR compensation is to be used, to set the averaging time constant and the measurement period.
Protect - This screen is for entering the protection limits for the cells and battery as well as the Fault values.
Balance - This screen is for setting the parameters for balancing of the pack
Evaluate - This screen is for the following:
SOC estimate - to select to not use the SOC points on the Cell-V screen and to set the minimum current level
Capacity - to select to calculate the capacity and the minimum cell voltage for the capacity calculation
SOH estimate - set the minimum %SOH below which the BMS issues a warning
Isolation Test - various settings for the isolation test
Control - This screen has settings for the digital inputs, digital outputs, analog outputs and the contactors
Communicate - This screen has settings for the parameters for the CAN and RS232 communications
