Yes, you can coil most electric cable just like a rope - its the twist that is key and anyone who has spent time coiling rope/sheets, say on a small boat, will find that the technique is the same.

Good Afternoon All,

I am a professional seaman.............. Wink

IMHO the best way is to 'roll' coil it rather than attempt to loop it - a bit like Tirfor wires.

The Konnwei OBD dongle has turned up today - now to see if I can get the CanZE app. up and running.............

Regards

Good Afternoon All,

I've been doing some reading up on the Zappi system and elsewhere.

From what I can gather the Zappi isn't as flexible as the Immersun in that there is no provision for a 'remote' CT facility like the Immersun with the T1070 wireless set-up. I've sent the manufacturers an EM querying this.

I believe the Zoe needs a minimum charge rate of 10A so I'd need some 2.5kW of exported PV to start charging?

As mentioned in my 'Heat Pump Install @ Courtiestown' thread I'm looking at making best use of the energy I have. Once the Solar ET is functioning as it should the need for the Immersun diversion will lessen.

Thoughts welcome.

Regards

Richard

Richard,

Don't know very much about it but just wondering why you need a special device for charging your Zoe from your house PV, unless you only want to charge it when there is sufficient PV available. If the Zoe is to be your main transport then it will have to be charged when it needs it rather than wait until there is PV available!

I came to the same conclusion when I started looking at real EV's rather than toy ones and PHEV's.

For us, whilst a 20 mile/day commute is not going to take much replenishing, say 6kWh, time of use would not permit that until the weekend, at which point, its 30kWh. Over some months, this would be entirely practical from excess solar, but, as has been said, the main reason to charge the EV is to drive it, not to store excess energy.

And that is from the single use case.

Add in a weekend jaunt, or ad hoc longer trips, my personal opinion is to keep it simple and either charge during the day when grid use may be augmented by free solar power, use destination charging, or charge overnight on cheap rate energy. That way you pretty much guarantee that the car will have enough energy for use.

Like using a washing machine, time controlled use and a bit of common sense probably covers 90% of what is ultimately possible. Im now entirely comfortable with a little usage coming from outside the generation curve.

That said, it would be nice if you could tell the EV what max charge rate should be. Can you do this or is it simply based upon the capabilities of the charger? ie Could I tell the EV to charge at 3kWh if it was connected to a 7kWh charger? What about 2kWh?

And then there is Oct through to Feb...

When we dip our toes into EV, it will be main car, so 200-300 mile real range and 70kWh battery. Charge it up overnight every week or couple of weeks and except for an exceptionally long run to remote destination, I am hoping that EV will be as easy to live with as our current vehicle.
