How I charge my ebike from J1772

[cal3thousand]

I skipped the lasts half dozen posts as this has gotten a bit off the rails.

I just wanted to post my appreciation for Jim's efforts to make the video. I saw the $150 control boxes elsewhere and thought that there must be an easier (and less expensive) way to do it. A couple resistors, a diode, and some wire is all it took. Now, that's the reason I'm on this site.

More choices in solutions is a great thing. Future readers just need to decide their level of comfort and choose a solution that both their cajones and their wallets can handle.

Thanks to the original if only the cluttter wasn’t here.

This post gave most interest being in Eu, we have Type 2 connector and I’m finding my adapter plug won’t function on the big ABB units see EL Drive App.

In fact over past few days I’ve found three Type 2 sockets and either switched off or don’t respond. At this moment without successful charge.

One such station. It’s on and App indicated were broken. Again no electrical charge.

I wanted this on my bike and didn't find anything readily available, so I figured it out and posted it so the next "me" would be able to easily replicate it.

You can buy a proper control box that does the status control for you:

Or you could just buy a ready made box:

Technically, since your charger doesn't check the PWM, it's not J1772 compliant. The protocol doesn't really specify what happens if that's the case, but I expect it would not be a problem unless you drew too much current. The TucsonEv control box is officially compliant (see list of compliant devices at the end of the page):

Look, I think in hindsight, the best way for me to have approached this thread would have been:

"Good work, nice solution. But for anyone else not as confident playing around with 6.6kw of unprotected power, be aware that there are some reasonably priced pre-built converter boxes, that would allow you to keep your standard wall plug for most charging, but let you charge with J1772 wherever you find them".

How about we pretend I said that, and leave it there.

Hi Sunder. I’m very much one of the people you mentioned & I’m having real difficulties finding the ‘off the shelf’ solution you mentioned. Could you please share some links for me to find such a charger.
I’m finding it frustrating as hell to get any straight answers off people.
Cheers for any advise/knowledge shared. Thanks.

Hey mate,

It's been 4 years since I posted in this thread. Can't believe I chose to pick that fight and get so caught up in it, but at least it's had the benefit of making the thread easily found by search engines. I've had a few PMs from people in your situation as well.

Anyway, I can't remember the supplier I got mine from, but I did find a replacement one pretty quickly:

I just noticed you're from the UK though, so that's not quite the right one for you, but the search term is "J1772 to <technical name for your country's plug>"

Alternatively, you could use a US to UK adaptor, or you can use the very common international IEC C13 adapter - A fair few chargers I got from China uses that type of plug:

Hope that helps.
