I don’t think I’d use a wireless EV charger simply due to the efficiency loss, especially from a company with so few technical specs (easily accessible) on their site.
Both from a financial perspective, but also that any energy lost to inefficiency is lost as heat.
I mean, they mention their efficiency as:
“Plugless is ~12% less efficient than corded L2 30amp 240V charging systems and ~7% less efficient than corded Level 1 charging systems.”
What does that mean?
12% higher losses? eg. 88.88% efficiency Versus a 90% baseline?
12% reduction in efficiency? eg. 79.2% efficiency versus a 90% baseline?
12 percentage point reduction? eg. 78% efficiency versus a 90% baseline?
Or something else entirely.
Not that big and abysmal efficiency.
