No, physics does not work that way. You are discussing torque (current) without RPM (voltage). However, this is not WORK. Work requires force AND distance. Torque by itself is not work.
Horsepower = Power = Watts = Torque * RPM = Amps * Volts
A motor at 0 RPM takes no power because it does no work. There is basically no draw on the battery, despite there being a ton of torque. The inverter converts 400V and 1A at the battery to 400A and 1V at the motor (400W). The battery sees only that 400W load, and all of this turns into heat in the motor. However, the instant the rotor starts spinning that voltage goes up, and thus the work being done goes up.
Yes it does. We're literally talking about the draw from the battery. You can graph the draw from your battery, and you can see that it does not go up as you go faster. In fact, it drops as you go faster. This happens because as the RPM goes up, the torque goes down, and the torque goes down faster than the RPM goes up due to the back EMF of the motor.
If the motor output went down but the battery draw went up, all of that would need to go into heat somewhere. Tell me, where is that heat, and why does the electric motor drop from 98% efficency at 8000 RPM to 20% efficency at 16000 RPM?
Here's the chart of
battery power vs speed in a Model 3. Explain how the battery is doing more work at higher speeds.

Let's do some math.
Plaid battery capacity = 97 kWh
1000 hp = 746,000 watts
746,000 watts for 9.3 seconds = 1,930 watt hours
746,000 watts for 15.2 seconds = 3,150 watt hours
1.93 kWh / 97 kWh = 2.0% - Dead on.
3.15 / 97kWh = 3.2%. - Nowhere near 7%.
But you're saying that we only use 2.0% like expected in the first 9.3 seconds. So to get to 7% in the next 5.9 seconds, we need to use up 5% of the battery in those 5.9 seconds. 5% is 4.85kWh. To do that in 5.9 seconds takes 3,000,000 watts. This would be 4,020 mechanical HP. But you're saying it's not, it's just ineffeiceny going to heat, and for the last 5.9 seconds, the motor is suddenly only 20% efficent despite being about 98% efficent 0-150 MPH. All without the motor turning into a molten slag heap.
Even if you do 7% over 15 seconds, that's 1,630,000 watts, which is 2,185 HP, or less than 50% efficency for the motor.
Sorry, but that's not happening, and your numbers are way off, and your understanding of how the electrical power output of a battery relates to the mechanical work done by the motor in an EV is off.
