PROBLEM ?? TSDZ2 With Casainho V1.0.0 POWER FLUCTUATION with 860C
[youtube]aURlfztgUZE[/youtube]
In the video first I started with Throttle at 20 and at second 35 I changed to 100.
Some time ago I detected that the Motor had sudden power drops, even reaching zero power, for no apparent reason. I thought it was a problem with HW. Perhaps an inaccurate indication of the Torque Sensor (TS) or the Cadence Sensor (CS).
However when I was recording a video to check the evolution of the TSDZ2 engine temperature with and without Thermal Pad and with and without heat sinks I noticed something inexplicable.
Power and PWM varied and fluctuated inexplicably.
The test was being performed in Vitual Throttle (VT) mode at the maximum level.
The FW Version is the latest, V1.0.0, with a 48V motor and a 63V battery.
I did the same test with two different motor and the effect is the same. One of the motor is new and the other has only 700 km of use.
Once in VT mode, power fluctuation is not expected to be an effect of incorrect TS or CS indications. Is this statement correct?
What are these fluctuations in Potency due to? will it be a consequence of the PWM fluctuation?
Why does PWM change suddenly?
When riding a bike the effect is very unpleasant because it is always present and can even be dangerous because if we are in the middle of a very steep climb, 15 to 20%, and the power drops to zero, it can cause a fall.
These fluctuations are very frequent as you can see in the video.
Is it some incorrect FW configuration? I only activated the Field weakening and the temperature sensor. I also changed the battery values according to the 63V. The other settings are the default settings.
Is it a problem in the engine HW that blocks the engine and forces the power to drop?
Could it be an FW problem?
Could it be lack of processing power from the controller?
I Hope you can Help me in this forum.
I love Casainho fimware a lot!!
