Re: Using a lightweight generator to charge Bosch e-bike bat

solar rig could be below 4 kg all in all for 100 W peak, 400 Wh/day average. This coupled to a 1000 Wh minimum pack to harvest all available energy even during a day off, and that's it. My last setup was 150 W panel on 1850 Wh pack, for a cross Europe tour of 7500 km in two month. Worked fine, max d...

Re: 2WD can increase regen efficiency?

the 2706 is plugged on a Phaserunner? If not, that might be a first interesting step. On a heavy hauler with only a 9C+ 2707 it was easy to heat it to 100°C in a long and steep hill, with Grinfineon 40 A. Phaserunner will limit this by better converting kinetic energy into electricity and reducing h...

Re: AWD without differentials?

It was done that way in 2011. One 51 V 13.5 Ah on each side, 8 mm² cables to controllers, and one small 8-prong cable to link packs and plug charger, solar, accessories, seat heater, music, lights. Upgrade is planned with a distribution block, 2 batteries and every electric device on it. A big node ...

Re: AWD without differentials?

In my velomobile front motors (Crysta 406) are piloted by two separate controllers with one splitted throttle input, no vectoring or correction of any kind. In speed control mode it's interesting to say the least. I was sure it'd be a mess to drive, with inner wheel increasing torque as speed reduce...

Academic publication on nanoscale view during cycles

Cell is LiFEPO4
http://news.stanford.edu/2016/08/04/sta ... batteries/
Very interesting as it shows fast charge could be less detrimental than slow charge for that LiFePO4 cell.

What would be the result with LiPo?

Re: Compact Field Oriented Controller, ASI + Grin, limited r

About power: this controller runs fine with 40 A batt current. For me, in 14s it's around 2 kW peak, no heat issue, fine. By going 20s it'll reach 3 kW but RPM will increase. A Justin wrote, it's fine for 1-2 kW range, and if higher voltage than usual is possible it could be stretched to 3 kW, maybe...

No heat troubles at all, bottom of controller is barely hot to the touch after a 250 m elevation trip under full load. Didn't checked...

Re: Compact Field Oriented Controller, ASI + Grin, limited r

With last software allowing variable regen and "good" tuning on Phaserunner, decelarating is nice and smooth. Total regen didn't really changed, as I more often use mild current and vary on a wide range from 0.4 V to 0.0 V (at 20 A max) instead of having 7-8 A all the time. Sometimes too strong, som...

Re: Carla Cargo trailer

Bought one a cargobike festival in Nijmegen.
Nicely done, automatic brakes when trailer pushes. Added regen on my own for all wheel braking.
No brake lift as long as you stay seated, as underlined before; seems safe to drive.

Re: Show me your electric velomobile.

One throttle, CA to receive and shape the signal, a "Y" to split it in two and go for the controllers. It means inner wheel in sharp turns will increase torque in response to lower rotational speed, but due to ackerman compensation of steering, it will effectively pull velomobile inside curve if I a...

Re: Compact Field Oriented Controller, ASI + Grin, limited r

Used to link ebrake to opposite brake lever. On a bike with front motor, I link the ebrake to rear brake lever; that way, one lever will give integral braking. Now it really works to full stop. Variable regen will introduce the last part of it. Just to find a way to link mech brake progressivity to ...
