Hi, I am facing difficulty in setting up the LED indication during Charging. There are 5 LEDs in the battery.
The LED configuration bit [BLINKMIDPT] is set, and it works like this:
90 to 100% LED5 blink at 'LED Blink Period'
80 to 90% LED5 blink at 'LED Flash Period', else LED5 off, if SOC is lower %.
70 to 80% LED4 blink at 'LED Blink Period'
60 to 70% LED4 blink at 'LED Flash Period', else LED4 off, if SOC is lower %.
50 to 60% LED3 blink at 'LED Blink Period'
40 to 50% LED3 blink at 'LED Flash Period', else LED3 off, if SOC is lower %.
30 to 40% LED2 blink at 'LED Blink Period'
20 to 30% LED2 blink at 'LED Flash Period', else LED2 off, if SOC is lower %.
10 to 20% LED1 blink at 'LED Blink Period'
0 to 10% LED1 blink at 'LED Flash Period'
For all the 'LED Blink Period' blinking, LED indication stays ON for 60seconds after the removal of charger.
For all the 'LED Flash Period' blinking, LED indication stays ON only for 'LED Hold Time' after the removal of charger. [What I need]
I want to know what the reason for the LED indication to stay ON for ~60 seconds after the removal of charging is,
and I would like to keep the duration only for 'LED Hold Time' in this case.
Could you please give your comments / suggestions?
From the data sheet, it should have worked like this:
"With the blinking feature enabled, as either charge or discharge occurs (assuming the segments
programmed are 0%, 20%, 40%, 60%, and 80% of RSOC), the state-of-charge ranges are as follows:"
90 to 100% LED5 on solid
80 to 90% LED5 on Blink, else LED5 off, if SOC is lower %.
70 to 80% LED4 on solid
60 to 70% LED4 on Blink, else LED4 off, if SOC is lower %.
50 to 60% LED3 on solid
40 to 50% LED3 on Blink, else LED3 off, if SOC is lower %.
30 to 40% LED2 on solid
20 to 30% LED2 on Blink, else LED2 off, if SOC is lower %.
10 to 20% LED1 on solid
0 to 10% LED1 on Blink?
But I am getting blinking at all states of charge (just a different blink rate and duration). It seems to be not working as mentioned in the datasheet. Am I missing anything?
