EV Charge Time Calculator

Charge time is battery capacity divided by charger output power. The grid below covers the common home charger power levels across typical battery sizes; the calculator underneath covers any battery and every one of the 445 chargers in this database. Real sessions run slightly longer because charging tapers near full; a 10 percent margin is a reasonable planning buffer.
