Welcome to EVs !!!
For charging stations at 40 amps, there are two choices:
Clipper Creek CS-50 or CS-60, $1995
Leviton 40 amp from Home Depot, $1099
Obviously, both require install and a 50 amp breaker. Any 40 amp continuous charge can charge your Rav4 in 5 hours, or about 28 miles added per hour of charger. If you don't need or want to charge at full speed, there are tons of choices of 30 amp and below units.
The charging cable in your trunk is only 120 volts are 12 amps, which means about 3-4 miles per hour. You can have it modified for about $300 for 100-250 volt operation. My already modified unit is for sale for $490.
Rav4's Tesla charger is 40 amps. Therefore, the "10kW" charger with 40 amp service is:
Power -- Voltage -- at 88% efficiency into the battery
11kW ---- 277 ---- 9.7kW (the maximum voltage that the charger can accept)
10kW ---- 250 ---- 8.8kW (hey, it just happened to be 10kW)
9.6kW --- 240 ---- 8.4kW (typical residential power in North America)
9.2kW --- 230 ---- 8.1kW (typical voltage in the rest of the world)
8.3kW --- 208 ---- 7.3kW (typical voltage at a public charge station in North America)
8.0kW --- 200 ---- 7.0kW (typical voltage in Japan)
At a steady 65mph on level, no wind roadways without heater use, the car will get 3.4 miles per kWh economy, therefore public charging will likely provide 5.5kW into the battery for 18.7 miles per hour charging. At home, that will likely be 8.8kW for 28.5 miles per hour charging.
I get 2.7 miles per kWh economy around town, therefore 14.8 miles per hour of public charging, and 22.7 miles from home charging.
Miles Gained per Hour Charging
Amps/Volts -- Where ---- City Drive ----- 65mph
12 / 120 ------- Any ------ 2.8 miles ------- 3.5 miles (supplied cable with car)
12 / 240 ------ Home ----- 6.5 miles ------- 8.5 miles (www.EVSEupgrade.com)
16 / 208 ------ Public ----- 7.5 miles ------- 9.5 miles
16 / 240 ------ Home ----- 8.9 miles ------ 11.2 miles
20 / 208 ------ Public ----- 9.4 miles ------- 11.9 miles (rare combo)
20 / 240 ------ Home ---- 11.0 miles ------ 13.9 miles (Clipper Creek LCS-25)
30 / 208 ------ Public ---- 14.8 miles ----- 18.7 miles (virtually all public charge stations)
40 / 240 ------ Home ---- 22.7 miles ----- 28.5 miles (CC CS-50 or Leviton 40 amp)
