Plans for the next test

So I think that the next test needs to be a bit slower at the beginning:
- get the audio verified
- get the videos running
- log the temperatures on audio, leave the thermometer by the controller, turned on
- start the AC logging
- start up the AC controller
- use the throttle to start up the AC motor (so I verify that the controller is taking current)
- *EDIT* check the AC output voltage with a meter as a check for the logging
- start up the DC motor, get up over 3600 rpm
- adjust the throttle to take less and less current until we it is in regen and showing the battery pack higher than it was at the start.
- log the heat spreader temp

That's the slow part, now for the fast part
- increase the load very quickly with the throttle until the controller reaches 300 AC amps
- Increase quickly .. 300, 350, 400, ... monitor the controller temperature
- shut it down with the ESTOP when it reaches ... 100C? The max operating temp is 125C

Paul - if you can confirm the max temp for the IGBTs on your spec sheet please? I found a Powerex 600V 600A spec sheet, but it may not be identical. 125C operating, 150C max

That should be about it!
