Using Fast charger in the states on my supercharger 2 2021 what do I need to make work.

[MTP206]

Please could anyone help. I have a 2021 supercharger 2 I'm on west coast of US and want to use fast charger I ordered from across the pond. I bought a step up but haven't used it because I'm not trying to ruin anything or void warranty. Please help thanks.

Do you mean 220 volts input plug ?

Yes I also purchased a set up to convert 220 -240 to 120

I asked about the 6 amp charger a few months ago in the US from the William the Bosch guy on the Bosch forum. I was told it won’t work at all, not made for 120v, not dual option as many devices have been. I dont think I would even try could be pretty expensive experiment.

I just checked, you are right, it is not multi-voltage just 230v 50Hz. The only concern that I would have using a transformer is that they tend to output 220v 60Hz and I am not sure how that would affect the output. I would be concerned as the charger has an internal switching power supply and if it receives 60Hz 220v instead of 50Hz then can it regulate the output down to the correct voltage of 36v. There are technologies that will do this but they are really expensive, I am thinking about the waveform regenerators that will give you a perfect 50Hz sine wave out that some people use in hifi.

Just a side note, I have bought bosch powered bike both in the UK and the US. Strangely my US based bikes came with a 110/220v charger and my UK ones are mainly 220V. I just wonder if they actually produce a 220/110v that would be ideal for you.

The minimum I would do in your position would be to get a 110v to 230v transformer then measure the output of the charger. If it is over 36v then I would don't use it.

It should transform the voltage. But it doesn’t appear to do any transformation on the frequency (50 vs 60 hz). I’d be hesitant to try that out on a couple thousand dollars worth of batteries and your bike’s controllers.

Ok thanks. Could you recommend a a couple if possible please

It also doesn’t mention anything about transforming the frequency. So it doesn’t seem any better in that regard. I’ve done some cursory searching, and I haven’t found one that does do that type of transformation.
It may work fine without that, but from my experience doing some circuit building, I’m mainly concerned that the different frequency might cause some of the charging regulation or battery monitoring to not work exactly correctly. Much of that stuff is highly dependent on timing of pulses. Causing an over charge/fire risk.
If you keep looking, focus on if the 110v output is 60 hz. Not 50/60hz, and the input is 220v 50 hz.
Are we sure that the 220v fast charger says 50hz, not 50-60hz?

Ok thank thank you so much.

Purchase 2amp for $75 , 4 amp for a little over 100 doing a google search...

36v batteries are actually charged at around 41.8-42VDC.
