Timer with monitor

inavitech

I working on designing a battery tester that would have a timer that would shut off once the battery reached a certain voltage. So I would like the timer to stop counting when the voltage drops to 16 VDC so I can record the discharge time. Then again when recharging the battery to automatically cut off the charger once it reaches 28 VDC. I saw some timers on the market but when I reached out to the manufactures they didn't have the ability to do that function. More along the lines of production line automation.

    You’ve not mentioned what level of accuracy you are after because solutions could range from simple to complex based on this alone.  I would have thought nearest second would be good enough which almost certainly means you could get a simple solution accurate to sub-second.  If you’re after millisecond accuracy then that’s likely more difficult.  Also, is this just a home project or product development?
