I would highly recommend the
JuiceBox 40A from eMotorwerks. Very interesting concept, you get cash if you opt for charging during low demand hours but it's totally your choice, you can also force it to go for the quick 2-hr charge... It's a smart charger you can control from your phone app and is also a much cheaper option than the 2K Mopar fast charger. Best is probably to install it as plug-in to a standard 220V 14-50 receptacle so, you can take it with you to other location. Installation specs are as follows:
For the JuiceBox 40 plug in (standard)
You will need the following:
A 2-pole, 50A breaker
A NEMA 14-50 receptacle ( NEMA 14-50R)
#6AWG copper wire with 3 conductors and a ground. If single conductor THHN wire is used, the ground may be #10AWG per NEC 250.122 calculations
Note: the neutral wire is not used, but may need to be present in the receptacle to be to code.
If for an outdoor installation, please add the following:
A NEMA 14-50R outdoor enclosure
Shade for the JuiceBox so it is not in direct sun, exceeding the 90°C mark.
