EV charging time calculator
Enter your battery size, the charger's power and the charge levels. The calculator follows the real charging curve, so the last percentages fill more slowly than plain division would suggest. The power buttons are the ratings that actually exist on chargers in Georgia.
Filled automatically from the battery size. Change it if you know your carβs limit.
The result is an estimate. The exact time depends on the car, the battery temperature and how busy the charger is. A cold pack in winter charges slowly for the first few minutes.
How long 20 to 80 percent takes
The columns are the most common power ratings in Georgia, the rows are typical battery sizes.
| Battery | 22 kW | 30 kW | 47 kW | 60 kW | 120 kW | 160 kW |
|---|---|---|---|---|---|---|
| 40 kWh | 1 h 14 min | 51 min | 34 min | 29 min | 27 min | 27 min |
| 60 kWh | 1 h 50 min | 1 h 17 min | 49 min | 39 min | 27 min | 27 min |
| 75 kWh | 2 h 18 min | 1 h 36 min | 1 h 1 min | 48 min | 28 min | 27 min |
| 100 kWh | 3 h 4 min | 2 h 8 min | 1 h 21 min | 1 h 4 min | 33 min | 28 min |
What the last 20 percent costs you
A 60 kWh battery. The last fifth barely notices how strong the charger is. It takes the same time on a 47 kW unit as on a 160 kW one, because at that point the pack sets the limit, not the charger. On a fast charger the last 20 percent takes longer than the whole 20 to 80 percent stretch.
| Charger | 20 to 80 percent | The last 20 percent | 20 to 100 percent |
|---|---|---|---|
| 22 kW | 1 h 50 min | 37 min | 2 h 27 min |
| 30 kW | 1 h 17 min | 30 min | 1 h 47 min |
| 47 kW | 49 min | 28 min | 1 h 17 min |
| 60 kW | 39 min | 28 min | 1 h 6 min |
| 120 kW | 27 min | 28 min | 54 min |
| 160 kW | 27 min | 28 min | 54 min |

How it is calculated
Two things set the time. First, how many kilowatt hours go into the pack, which is capacity times the share you are adding. Second, how fast they go in, and that part is not constant. The calculator splits the range into ten bands and in each one takes the lower of the chargerβs power and what the car will accept at that state of charge. About 6 percent of the energy is lost as heat on DC and 11 percent on AC, and that is accounted for too.
Frequently asked questions
How long does it take to charge an EV?
It depends on the battery and the charger. A 60 kWh battery from 20 to 80 percent takes about 39 minutes on a 60 kW charger and 27 minutes on a 120 kW one. On a 7 kW home charger the same top up takes 5 h 47 min.
Why does charging slow down after 80 percent?
The fuller the pack, the less current it accepts, because the battery management system protects the cells. That is why a 60 kWh battery on a 120 kW charger needs 27 minutes from 20 to 80 percent and another 28 minutes for the last 20. On a long drive two short stops to 80 percent beat one long stop to 100.
Why am I not getting the power written on the charger?
That number is the charger's limit, not your car's. The real rate is the lower of the two, and it also depends on the state of charge, the battery temperature and whether another car is sharing the same cabinet. A cold pack has to warm up first, so the opening minutes in winter are always slow.
What is the difference between AC and DC charging?
An AC charger feeds the car through its onboard converter, usually capped between 7 and 22 kW, but it holds that power almost all the way to 100 percent. A DC charger bypasses the onboard converter and feeds the pack directly, which is far quicker, and it is the one with the pronounced taper at high states of charge.
