Regen braking: confirmed!

[jhautz]

This is cool Brian. I always wanted to do this test myself but never really had a good enough multimeter to do it. Especially after a little experiment I did myself a couple weeks ago. I have actually been meaning to start a thread on this very topic. I have heard for a long time that they did have regenerative braking in just about all ESCs but never saw any proof of the fact.



I'm hopeing someone can answer why it is that I see 10-15% better milage when I run mechanical brakes? This is on the same truck on the same day on the same track with the same setup and batteries. I did some testing the last time I went out for a practice day and wanted to see what effect the mechanical vs motor brakes had on run time. I ran 2 5 minute runs with the mechanical brakes on 2 different packs, and then took the mechanical brake off, and charged the packs back up recording the amount of energy I put back in each one. Then ran two 5 minute runs with the mechanical brakes taken off and used motor brakes. I tried to drive just as hard with both brake setups and ran 2 trials on each just to add a little extra data.

But for sure, both runs with the motor brakes used more mah from the packs than the runs with the mechanical brakes did.

A day or 2 after I actually did this I realized I could have used my eagle tree to get better data. Next time I will do it that way.



I just dont get it, the evidence would support the opposite effect being true. Longer run time with motor brakes.

Wondering if anyone has any thoughts?
