Can anyone tell me how to go about charging my e-bike using type2 public charging points please. Any info/advice would be greatly appreciated. Thanks
Edit: it’s a 20s14p li-ion battery 72v 42ah. At the moment I’m just using a 25A variable portable charger plugged into the mains(uk) which connects via an Anderson 50A 2 pole plug.
But my goal is to be able to use the numerous pubic charging points here in the uk. Type2 mennekes plugs seem to be the most common & someone told me that I’d need an Orion bms. But apart from that I’m finding it difficult to source the info I need & anyone I’ve asked is either clueless (like me) or seem reluctant to share any info with me. As I said, any info or advice would be much appreciated. Cheers.

I have not used public charging stations, so the info I have is just a guide to potentially help you find the info you need. If you have more info than you've listed so far, providing all of the info you do have may help us help you more thoroughly.


Are the charging stations free? If not, then you'd have to check with the company servicing the charging point for how to setup an account with them, etc., if it isn't just always active, and free (not sure if any of them are). Each company may be different in how they work, so you would have to check with each one you wish to use to find out. There are some threads about some of them in this list

As for the plug, if it is the J1772, then there's a number of threads including a sale thread for the connector:

These threads mention or have discussion about the connector in them:

If it's chademo, then these two threads have a bit of info; may not be what you're after

and these posts mention the word but I don't know if they have the info you want

If the station you want to charge at requires communication with the battery, so that it knows what DC voltage to provide, at what current, and when to stop providing it, then you'd need something in there that can do that. If the Orion will do that, then that's one option. There might be open-source projects out there to do it, too, I have not looked into this. Do you know what the standards are for the specific stations you want to use? I found this summary
https://pod-point.com/guides/driver/ev-connector-types-speed
Similar to phone charging cables, car charging cables tend to have two connectors, one that plugs into the vehicle socket and the other into the chargepoint itself.

The type of connector you need varies by vehicle and the power rating ("speed") of the chargepoint. *

Electric vehicles either have a Type 1 or Type 2 socket for slow/fast charging and CHAdeMO or CCS for DC rapid charging.**
Most slow/fast chargepoints have a Type 2 socket. Occasionally they will have a cable attached instead. All DC rapid charging stations have a cable attached with mostly a CHAdeMO and a CCS connector.
Most EV drivers purchase a portable charging cable that matches their vehicle’s Type 1 or Type 2 socket so that they can charge on public networks.
but it doesn't mention what's actually required, and it doesn't mention by the mennenkes name the connector type you've found most common, but it does show it as type 2.

If the station just provides AC power (rather than DC) then it shouldn't need to talk to the battery, and all it needs (at most) is ID information to tell it to provide power or not. That is generally simple to do (it's what the various J1772 adapters Iv'e seen appear to do).

This wiki article on the Type 2 connector shows at least two very different designs in images and diagrams.
https://en.wikipedia.org/wiki/Type_2_connector
This also shows a useful diagram of what is provided in different modes, which indicates type2 does have a pure-ac mode, so that you could use it with your onboard battery charger, possibly without a complex BMS / charger communication setup.

OpenEVSE appears to be a DIYable charger for J1772, it might be adaptable to your stations if they aren't J1772.

Thanks for the info & links. There’s a lot for me to get my teeth into & I’m really grateful for your time & interest.
I will definitely post updates on this thread of any progress I make in my endeavour. I’m sure it would be of interest to
Lots of people. The charging points aren’t free at but can be fairly cost effective. It’s a matter of convenience more than anything. I have a map from which I could plan any long journey from point to point taking into account my battery use/max distance etc.
I’m planning to upgrade my battery soon to a 30s14p 18650 li-ion which at 420 cells Max’s out my bikes capacity in terms of its frame size/battery box & though this will give me more power obviously I’ll have the same range. So I’ve been obsessing over increasing that capacity. Altering my frame, welding, custom 3D printed parts or carbon fibre moulding. When most of that wouldn’t be as necessary if I concentrated my efforts on faster charging instead.
I have a plan to eventually get a small detachable side car fabricated which could house a rather large battery & plan to be able to ‘fast charge’ this at public outlets for really long journeys. I’d also be able to port luggage on the side car too with practically unlimited range. I have a day dream of heading off into the hills & pitching my tent, my sidecar could perform as a campsite power supply. But in the real world, just having the ability to visit my family up north or go on any journey no matter the range is achievable I’m sure. So that’s my goal.
At 42Ah my battery will still need charging every 30miles approximately @40mph so even with fast charging capability on long journeys it would be a stop/start pain so the sidecar would solve that & I’m looking at going for about 120 mile range. So I’ll probably need around 1000 cells (18650) in the side car. I’ve also (as a total amateur) been looking into using modular packs connected in parallel for the sidecar . But for now just figuring out how to charge the bike itself is my main concern. I’ll be sure to look at those links & I’ll let you know of any progress I make.
Thanks once again...Cheers.
