Hello everyone,
I have an EV model, and I would like to calculate its efficiency, i.e., inverter efficiency, motor efficiency and motor efficiency, and I would also like to draw its efficiency map. What approaches can I use to achieve the said objectives.
For now,
- I have connected a power sensor at the battery side, which provides a average power at 0.001 sec.
- A three-phase power sensor at inverter's output, which apparantly provides higher power than input.
- A rotational power sensor, which also provides averaged mechanical power at 0.001 sec.
Following are the challenges which I am facing.
- Higher inverter power.
- Negative power as well, depending on the drive cycle especially when torque is negative during deceleration.
I am attaching the EV model. Your guidance on this will be highly appreciated.
