20A battery charging times

How to Calculate the time of Charging and Discharging of battery?

If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).

Debunking the 80/20 limits on EV battery charging: More

The physics of battery charging is that the time for an EV battery to charge from 0% to 80% is very roughly the same as it takes to go from 80% to 100%. (LFP chemistry batteries start slowing at slightly higher percentages, but the effect is much the same: DC charging slows as you near the top of the charge). This means that if you don''t need that last 20%, don''t waste your time
