When the DISP pin is pressed and a high-to-low transition of the pin is detected, the LED display shows the state-of-charge for LED Hold Time. The state-of-charge can display the RelativeStateOfCharge() or AbsoluteStateOfCharge(), based on the [LEDMODE] setting.
The state-of-charge threshold can be set according to the number of LEDs available. The following table shows an example for data flash setting with 5-LED display.
State-of-Charge(1) | ||
---|---|---|
Current() > 0 | Current() ≤ 0 | |
LED1 | CHG Thresh 1 to 100% | DSG Thresh 1 to 100% |
LED2 | CHG Thresh 2 to 100% | DSG Thresh 2 to 100% |
LED3 | CHG Thresh 3 to 100% | DSG Thresh 3 to 100% |
LED4 | CHG Thresh 4 to 100% | DSG Thresh 4 to 100% |
LED5 | CHG Thresh 5 to 100% | DSG Thresh 5 to 100% |
If SOC drops below the flash alarm thresholds in charge or discharge, then the LED display also flashes with LED Flash Period per the CHG Flash Alarm or DSG Flash Alarm settings shown below.
State-of-Charge | ||
---|---|---|
Current() > 0 | Current() ≤ 0 | |
Flash Alert | 0% to CHG Flash Alarm | 0% to DSG Flash Alarm |
In PERMANENT FAILURE mode the StateOfCharge() display is replaced with the PERMANENT FAILURE mode display consisting of LEDs 1, 3, and 5 blinking.
If [LEDPF1, LEDPF0] = 0,1, then the LED display shows a state of health display for LED Hold Time after showing the state-of-charge or PERMANENT FAILURE information.
If [LEDPF1, LEDPF0] = 1,1 and the DISP button is held pressed for LED Hold Time when first display completes, the LED display shows a StateOfHealth() display for LED Hold Time after showing the state-of-charge or PERMANENT FAILURE information.
State-of-Health | |
---|---|
LED1 | SOH Thresh 5 to 100% |
LED2 | SOH Thresh 4 to 100% |
LED3 | SOH Thresh 3 to 100% |
LED4 | SOH Thresh 2 to 100% |
LED5 | SOH Thresh 1 to 100% |
