Wonder if they'll learn something from this? Or rather, remember something important:
When running a current through a cable, the resistance increases as the cable heats, the less efficient the system is unless it's the heat you actually want out. We should all know this from CPU cooling: The higher the load, the warmer the chip, the slower the system gets.
Same thing applies to electric motors: More load (faster revolutions/heavier mass being moved) = warmer the motor/increase in resistance = more drain on the battery = shorter range due to reduced efficiency.
Cooling the motor will help reduce the loss of efficiency of the motor = less drain on the battery = longer range.
Also, adding more than one fixed gear (Think it's the Porsche Tycan that has two gears) means you don't spin the motor faster to maintain higher speeds = reduced current/draw on the battery = longer range. (this is WHY Porsche added the second gear, too).
After all, people don't want a car just to pootle around town, stop/start traffic, short range, which is what the Nissan Leaf was designed for, and the other EV's have copied - occasionally people want to go further afield, and adding larger batteries adds mass to the vehicle, hence load on the motor, hence reducing the kWh to Miles ratio... Think the BYD Seal started at 4.5 miles per kWh but that dropped to 3.2 kWh during the test trip on the motorway. The BMW was worse, as was the Merc, and the Tesla was around the same as the BYD - an interesting review of EV ranges that demonstrated how range depreciates as the motor warms up while under a constant, prolonged, load.
And now we're seeing the same thing with EV charging: One more reason why, when charging an EV, it starts quick, but the charging slows down over time as the cable warms up. Might only be a small impact, but it is there.
So now they've tried water cooling for the charger: Will people look at water cooling for the motor? Yes, that's the reason for the icon...
