Is it 500km highway or 500km city driving in those 15min? Is it in the winter or in the summer? Is it on a rainy day? Is there snow? Is there head wind or tail wind? 500km is a completely useless unit for charging speed and battery capacity without context, and all these things have a huge impact on the range you actually get from the exact same amount of power. Using kW and kWh for charging speed and capacity is unaffected by any external conditions.
It's fuckin simple
It says 500km
It's 250
Not only is it unaffected by external conditions, it's a completely useless number for 99% of people, too!
Indeed. Usually what happens is businesses will bend the truth or flat lie until regulations force some standard (and even then, some companies will continue bs-ing).
Although, kW and kWh don't really give you anything meaningful to compare, because vehicle weight and motor efficiency curves differ. It would be like comparing gasoline cars based on tank size.
What's needed is some rating system similar to how city/hwy mpg is estimated.
