Which formulas do I need to calculate current of a 3phase induction motor
The RPM is determined by the frequency and does not directly effect the current. The current is more closely related to torque. Some useful relationships are:

Motor speed RPM = 120 X Frequency (Hz) / Number of motor poles (4 poles for the Tesla I think)

Input power to the motor, Watts = Volts X Amps X Square Root of 3 X Power Factor

Horsepower output = Torque (Ft-Lbs) X RPM / 5252

Input Power X Efficiency = Output Power

1 Horsepower = 746 Watts

The Tesla motor is very efficient, 0.95 or higher

For constant torque operation, the voltage applied to the motor is proportional to frequency.

The Tesla motor can provide constant torque up to some frequency limit. Above that, the voltage does not increase any more (or perhaps it increases at a slower rate). That allows the motor to provide constant power.

Re. Test Data

It appears that the voltage and current for the test data are battery voltage and current. The power at the battery is just watts = voltage X current. The inverter is between the battery and the motor. The Tesla inverter efficiency is also quite high, perhaps 0.95 or higher.
