So I've noticed a pattern amongst commercial ebikes where the motor power listed is often something like "nominal power" or "rated power" expressed in watts, and the battery capacity is often expressed in "max capacity" in watt-hours. I've also seen a few cases where "experts" on ebikes have stated that a well-balanced ebike is one where the battery Wh and the motor W are close to the same value. I think I've heard that referenced most in YouTube videos of either shop owners or people at expos repeating that saying.
I'm digging for a specific example still, but a generalized example would be something like a bike with a 10s4p battery being called a 42V, 504Wh pack, and with a 500W motor. That then makes the bike both sound more powerful (42V vs 36V), and more balanced. By contrast, if we use our more typical (read realistic) ratings, we'd call this a 36V, 12Ah pack. And as for the power of the motor, we know that it depends on what the controller will send into the motor. So if we assumed the common commercial controller default of 15A, that would make peak power as much as 630W on a full charge (or 432W at nominal capacity).
So I'd like to know if you guys think that this is an attempt by the industry to come up with figures that are digestible by the general public, or do you think it's more deceptive and the manufacturers are just trying to skirt under regulations or meet that imaginary capacity/power balance?
