Charging when ebiking

(1/2) > >>

Thomas Martinussen:
Hello!

I wish to charge my spare battery when ebiking (hiking). Ebike have a trailer with some room for a solar panel. Bike battery is 36volt, and 14a. 220 volt home charger charges the battery with 1,8a and 42 volt. (1,8ax42v-75w)?  Is this possible?

TheHolyHorse:
I don't know the power of a typical solarcell that's gonna be suitable for your application. But as long as you can get good enough power from a solarcell to be worth it, sure it's most certainly possible.

Hi, not realy.
I Charge my e-bike with Solar in my Gardenhouse. I have 2 Panels with around 170W. The Voltage what you get is not enough from the standard Panels (19V-21V), you need 2 with serial.
The good Solarcharger makes MPPT,  this is a technique for maximum performance of the Panels (Voltage and Ampere for max Watt).
I charge an 12V Battery, this drives my automower, camera, and many others. If ich Charge my e-bike i use an Step up driver with adjustable Current and Voltage. I have noticed that most e-bike batteries are very sensitive to the voltage applied. 41,8V --- with 42,8V Bike says Battery error :-(.
You made many equipment for this way to Charge, I think it is easier to take a charger. Low weight ;-)

TheHolyHorse:
As long as the panel outputs enough power you can just boost it the actual voltage output from the panel doesn't really matter. You're gonna need additional circuity to handle the charging anyway.
