If you install a night-rate/off-peak ESB meter to charge your car exclusively, you'll get 1. for free with the ESB installation, just read the meter.
Can you have 2. without paying for 1.?
If these are the people who got the Norwegian government contract, I'd be very slow to ignore them.
What facilities does the car manufacturer's unit offer?
Also, is it worth €310 + VAT for both?
...need to monitor usage for business use.
Will you be using the car manufacturer's wall charger unit or a 3-pin plug to charge the car? If your car will be used during the day, you can't afford to have it plugged into a charger, unless its a public rapid-charger, for extended periods.
Believe me, night-rate is the only way to go if charging at home. Differentiating domestic electricity usage from car-charging usage will be impossible otherwise.
I get the impression that you may have jumped on a band-wagon without much thought. Why all the questions when you've already bought a car?
The charger itself can monitor usage with the add-on, or something like an Efergy monitor with CT clamp around the live feed, or a simple DIN-mounted energy monitor added to the fuse board that the supply to the charger runs through would do it. Maybe I’m misunderstanding your point, but this is very possible to do.Believe me, night-rate is the only way to go if charging at home.

We will use the night-rate as suggested by others too.
Yep agree with all that. Was querying this -There are many reasons to charge EVs with off-peak electricity, one being the cost of the electricity, another being increasing the demand for electricity at peak times, putting extra demand on generation and distribution networks thereby potentially increasing infrastructure costs, and increasing the fossil fuel demands where no green generation alternatives exist.
If we are serious about accruing any benefits from EVs, we need to look beyond next year's automotive fuel or tax bills or BIK charges.
Fair enough. Still don't understand the point about it being impossible to differentiate domestic from EV charging without night-rate, but let's move on...I don't agree with running high-demand electrical appliances (washers, dryers, etc) at night-time or unattended, there are too many risks and too many delayed or failed recalls of faulty equipment resulting in too many fires.
Ah gotcha, the ESB meter would give you a nice bill in the post each month, already in Euro and all that, you'd just file it with your accountant. Whereas the likes of this you'd need to go to your fuse board each month and see what the reading says, it would be in kWh which would need to be converted to Euro, and a basic model would not understand day vs. night rate either of course...The off-peak electricity meter from ESB (or another supplier) results in a detailed, monetized bill for electricity consumption from that off-peak meter at that address. I don't understand how any other method of capturing consumption can do this for an EV or another consumer device without estimates, percentages and manual interventions, particularly where multiple devices are powered via the same meter.
