Thanks for the response, that really is the best way to control them!

In the UK the charging points are mainly 3KW Type 2, or 7KW Type 2, with some 43KW type 2 available as well.

As well, it would be good to carry around 2 x flatpacks so that I can charge from 3 wall sockets. Drawing 20 amps MAX for the eltek through two plug sockets, and then 13 amps from another 3rd socket. Most ring circuits are 36amps here.

Having the arduino switch the current on the flatpacks is the icing on the cake! Thank you very much, I will definitely be building that controller!

Thanks!

Yes, the reason I ask is that I have built something similar for my diesel bike project.

The lever on the governor is very hard to move, so takes a lot of effort. I drive the lever on the governor with a servo motor, and drive the servo with a controller.

The controller takes input from the throttle via a cable that moves a linear pot. After a while it has been reliable and required very few tweaks, just wondered if I could do that same with the regen lever!

I am now trying to find the sevon DVT software thats compatible with the 1.6 dongle. Lots of places say its easy to get, but I have only been able to find the 2.0 version. Trying to avoid buying a 1.6 dongle second hand, only to find out I am unable to get the software

With the DVT software, do I need to load a base configuration, or can it pull the configuration down from the sevcon?

Ah ok I get it.

So the real question is, how much voltage drop do the Flatpack2 take before they go into protect mode?

That I will have to find out, because I can then look at the voltage cutout spec (for example the rsp-2000).

Thanks.

further thoughts.

With a Type 2 Menenkes conenctor set at 7.2KW, I can use many charging points.

However, onboard, plus 4 Eltek flatpack2 he's = 9.3kw.

Can I wire 2 flatpacks in parallel and then another small power supply in series to make up 7kw?

Y'all need to redo your math, I believe its been changed to 30 mins for £6

So a £6 charge using my chargers nets 4.65KWH total usage in 3 minutes. vs 40p at home.

I'm disappointed with how many people that are upset by this news. All they need to do is switch to Ecotricity and they'll also get a good feeling about helping to save the planet.

If I can afford to double my gas and electric bill, I would switch to them. The cost saving for not having to pay the £5 at the charge point doesn't outweigh my double bill (unless I severely ramp up the use of charge points)

I disagree.

With a my home made "fast charger", I can pull a full charge in 1 hour and 45 minutes on a ZF13.0 pack. They are 44KW charge points as well, so I can pull a total of 9.3KW with a menenkes plug. Charge tank is pointless in the UK and the diginow is too expensive compared to the home made alternative (imo)

If I am using the motorway network to get around, then its the only choice I have, that's the biggest issue here. There are plenty of other chargers available, but ecotricity have monopolised the motorway charging market.

£15 for £1.44 of energy isn't fair (based on my home rate) and is more money to run than the Ice bike I have.

Their energy tariff for my area is more than twice the rate I am using now, so switching to them isn't viable.

EDIT: granted this isnt the "end of the world" but if you have just invested £3000 on a diginow charger, to be able to use motorways more efficiently, then this is a big blow.

@alexanderfoti
I've used almost all my means buying the bike ;-)
The HP PSU's available at a low cost, maybe 1/4 or 1/5 of the elcons, and it delivers in exces of 50amps.

Would like to see the total wiring mess though ;-/

I know the feeling! The elteks can be had for £80 or so each, so for £320 you have 8KW of charging capacity!
