36V BBS02 Issues #178

Open emeikei opened 1 year ago

emeikei commented 1 year ago

So I'm trying this on my 36V BBS02 (STC15F2K60S2) and none of the power or speed settings make any difference.
Throttle is just on full or off. PAS is the same. No matter how the assist levels are setup, I just get full on. Global/Max Current makes no difference. No idea what current it may be drawing. Throttle/Start Current makes no difference. Just goes straight to full on. Walk mode is full speed. But I am able to change the data displayed. Event Log voltage is 0V even after calibration. But controller temperature seems good.

I have flashed the bafang 52V firmware and it seems to work fine. But then flashing this again gives the same issues. I've also tried previous version but still the same.

I was gonna try this firmware, but since I have a 36V controller on my BBS-02B I'm hesitating since I saw this issue.

@danielnilsson9 Is there a technical reason why this would not work on a 36V BBS-02B? If not, I'll give it a go.

I have no clue. I would expect the 36V BBS02 controller to have the same hardware as the 48V but I'm not sure.

I have only tested this on 48V controller. I'm not aware of anyone who has reported to successfully use this on. 36V version.

Please report your results if you decide to go ahead. Just make sure you have access to the original firmware if it doesn't work.

@emeikei I was gonna try this as well, but I don't have the original firmware for my BBS-02B. You mentioned that you had recovered back to a Bafang firmware for your BBS-02. May I ask where you found that firmware file? Thanks!
