SLUUBT5C November 2018 – June 2021 BQ40Z80
This LED feature enables LED blinking until the midpoint of each LED segment. The blinking occurs between the bottom and the midway point of each programmed segment level; thus, providing more granularity as to where the charge level is within that LED segment. If the LED configuration bit [BLINKMIDPT] is set, then this blinking feature will work as indicated below:
With this feature disabled, as the charging or discharging occurs (assuming the segments programmed are 0%, 20%, 40%, 60%, 80%, and 90% of SOC), the LED display of state-of-charge ranges are as follows:
90 to 100% | LED6 on solid, else LED 6 off, if SOC is lower %. |
80 to 90% | LED5 on solid, else LED 5 off, if SOC is lower %. |
60 to 80% | LED4 on solid, else LED 4 off, if SOC is lower %. |
40 to 60% | LED3 on solid, else LED 3 off, if SOC is lower %. |
20 to 40% | LED2 on solid, else LED 2 off, if SOC is lower %. |
0 to 20% | LED1 on solid |
With the blinking feature enabled, as either charge or discharge occurs (assuming the segments programmed are 0%, 20%, 40%, 60%, 80%, and 90% of RSOC), the state-of-charge ranges are as follows:
95 to 100% | LED6 on Blink, else LED6 off, if SOC is lower % |
90 to 95% | LED6 on solid |
85 to 90% | LED5 on solid |
80 to 85% | 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 |
The blinking occurs between the bottom and the midway point of each of the programmed segments during charge or discharge. In this example, the segments programmed are 0%, 20%, 40%, 60%, 80%, and 90%; the midway points are 10%, 30%, 50%, 70%, 85%, and 95%. If the range is defined differently, then the midpoint where the blinking occurs is accordingly different. If the segments are programmed such that the midway point is a decimal point, then it rounds down to get to the next whole number. The blinking follows the LED Blink Period. If this feature is enabled, it will work when [LEDCHG] is set or cleared. When the LED is operating due to the DISP being pressed, the LEDs are on for LED Hold Time (default is 4 s, so at a default a blink period of ~500 ms, there would be at least 7 to 8 blinks in the 4 s—if [BLINKMIDPT] is set).
