The highest peak of the Canary Island La Palma is the Roque de Los Muchachos with an altitude of 2426 m. Thomas Senkel went there with his 5000 W Power Ebike. On that winding road the speed is almost the same as with a car. But a lot more fun!
For the 70 minute trip only 14.5 Ah (with 14s LiPo) were consumed. Thats just 25% of the nominal battery capacity of 58 Ah. Of course, the power consumption depends on speed, pedal power, altitude difference, etc. On the downhill ride, a lot of energy can be recuperated with the motor, working as a generator.

Hammer. So muss das gehn. Diese Höhenmeter Demo ist mir viel sympathischer als die ganzen Speed Hirnis. Wieviel Ah gehen bei der Downhill Reku wieder rein?

Pulst Du die Batterien wieder zurück im Betrieb durch die BackEMF des Motors ? So sollten sie dann noch länger halten...

overunitydotcom Genau, der Controller kann rekuperieren und so einige Energie wieder zurück gewinnen. Dazu habe ich am Bremshebel einen Mikroschalter angebracht. D.h. bei leichtem Ziehen der Bremse bremst erst der Motor und nur wenn man stärker zieht, die hydraulische Scheibenbremse dazu.

Stark !!! Sowas würde ich gerne an meine Hercules MX1 anbauen, am besten den Motor direkt an das Hinterad schrauben dann hätten die Akkus platz wo sich vorher Tank u. Verbrennungsmotor befanden... hähäh am Vorderad 2500 + 2500 Watt am Hinterad da ich auch im Winter fahren muss, würden mir völlig reichen !!! Ein Hercules E-MX1 Sachs 2x2 hähähähähä ;-)) Klaus 777³

As much as I love e-bikes, I love flying e-volo's more. What is the status with the e-volo flight tests. I have not seen any updates.

Den Motor hab ich selber entwickelt (und gewickelt). Der Motorcontroller ist von Kelly. Akku Pack ist custom made.

From which altitude did you start and what are the repsective weights of you and the bike andhow long did it take you to ride up there? Just so i can make a rough estimate of the efficiency of the electric drive unit. I'll estimate you pedaling at 160 watt constant.

That was awesome! When the motor is regenerating how many watts does it output?
@forschungsbuero
@forschungsbuero 9 жыл бұрын
That is adjustable at the Kelly controller. At the moment, I set it to 25%. I have measured the regenerative current with approx. 8-10 A (= 400-500 W). You could set more, but even downhill, I would like to have some speed instead of creeping :-)

Pedelec? Habt Ihr einen Drehmomentsensor eingebaut? (integrated torque sensor?) Schöner Riemenspanner! Überrascht mich, dass die Shimano Nabe 5kw aushält...
@forschungsbuero
@forschungsbuero 9 жыл бұрын
Nix Pedelec und kein Sensor, sondern Drehgriff. Der Riemenantrieb wurde früher mal von Thun hergestellt. Warum sollte die Nabe das nicht aushalten? Die Motorkraft geht direkt an das Gehäuse. Und das sind ja auch "nur" etwa 70 Nm. Der schwächste Part sind dabei die Speichen. 5 kW ist auch nur kurzzeitig. Der Controller hat 50 A Dauerstrom.

forschungsbuero Schade.. mit Sensor fühlt man sich wie Superman. :) Bezüglich der Nabe.. war ein Denkfehler... Danke für die Antwort

***** priorities in life are always difficult. But yes I figure that the electric car revolution, artificial intelligence, UFOs and spiritual reality are significant topics for me to focus on.
