47V 14,7Ah Akku auf 36V ausgangs leistung welcher Wiederstand?
Hallo zusammen ich habe ein 47V 14,7Ah akku und soll an meinem fahrrad angeschlossen werden was 36V max. eingang unterstützt. Was für ein wiederstand benötige ich. Ich bin auf 0,7971014493 ohm gekommen aber was soll das für wiederstand sein.
Ich bedanke mich für ihre hilfe.
This cannot be used with a resistor either a DCDC in between or just a suitable battery.
At DCDC you have the problem that you have to find one that gives you so much power.
I don’t know what you expected. I can guarantee you it’s Murks. You can’t just adjust the voltage with a resistor. Finally, the current would have to be constant. Ohms law and so.
U = R * I
ok and what else would I have to use to get to 36v?
A battery suitable for the device. Everything else will not work. If you were to bring the voltage to 36V via DC-DC converter, the depth discharge protection and the capacitance measurement would no longer work.
ok thank you then must have a new battery
It is hot Againststand (without ie) and a resistance alone is not suitable to provide the voltage for consumers with fluctuating current demand to reduce and keep stable.
Just get a 36V battery.
What would they say to them instead of a new battery, because it is not cheap. Is there a device that makes it possible to do something like this.
> instead of a new battery
Apart from the power loss that would be wasted in such a voltage conversion: there is probably no more favorable solution than a suitable battery. Such a bicycle has a very neat performance (100W upwards), because you don’t get far with craft solutions and in doubt the components are quickly transformed into a smoking pile of scrap.
Yes, a new 36V battery
You have no idea about technology, leave it before someone gets hurt!
White how to cadge things have rarely used a restand but never by 47v
I can only repeat
I have the original charger from the battery and also the plug for the connection to the respective vehicle
Ah, yes, you have a 47 V charger with overload protection
I would repeat myself…
The battery can be loaded with the charger.
The preresistance would be dependent on the power taken, and this varies constantly – and how do you want to load this thing safely????
