Here is some info:
If Patrick said it you can pretty much take it as gospel.

Driving my truggy on asphalt with a Neu 1512/2Y (1400kv), Jazz 55 ESC and 10s1p A123. I marked the amp and voltage peaks where i applied brakes. The green line represents motor rpms. The eagletree logger records positive Amps (not negative amps) and voltage does rise instead of falling -> the battery is recharged. Amp Peaks around 15-20A with voltage rising by 1.3-1.4V
A similar behaviour can be seen with MMM and BK ESC.
Quote from Pdelcast about MMM EscQuote:
The braking is regenerative because it has to be -- can't dump that much energy anywhere but back into the battery. (The battery is used as a load, but using a battery as a load mean charging the battery...)
It is not, however, optimized.
Still gets fairly good efficiency up to about 35% braking power -- above that the conversion efficiency gets lower. |
