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.
