In the article, it states "you can still use the base 3.3kW onboard charger. But this time you charge while plugged into an upgraded 240V system. This significantly reduces your charging time to about 4 hours and 30 minutes.". So I'm confused....if we upgrade to a 240V outlet, can we use the charger that comes with the car (as stated above) or do we need a level 2 charger?
