Exactly. A modern EV drive train could be 85-90% efficient from battery to the road. To improve range by 30% you'd have to get more than 100% efficiency. There just isn't room for that level of improvement in the electronics. Now, maybe you could add 30% by reworking the body to be more aerodynamic and removing weight. But, that's not what they're claiming. Always be suspicious of claims that defy logic. The best they could hope for is to reduce the inefficiency by 30%. I mean, I'd believe they could take a 90% efficient drive train and make it 93% efficient. That's 30% less inefficiency but you'd be hard pressed to notice the difference.
