Monitoring electric vehicles: some thought from the UK

Calahonda52

Electric cars and vans are becoming a feature of many company fleets and with the advent of clean air zones and vehicles with a 200-mile range it is a trend that is only going to increase. Organisations that have so far not monitored electricity consumption for battery charging are going to have to think about it and it is recommended getting systems in place sooner rather than later, and not just for the obvious reporting reasons. Last week we were discussing a scenario where an EV user could charge up at work and flog the electricity at 40p per kWh to their supplier at home if they had the right smart-meter tariff.

DEFRA's GHG reporting guidelines now include factors for both battery electric vehicles and plug-in hybrid electric vehicles (can also be used for range extended electric vehicles). But these factors are only needed when actual energy use data is not available so now is the time to make sure charging of electric vehicles, whether on-site or at-home, is being metered. If you don’t meter it then then you won’t be able to calculate energy efficiency (km/kWh) or cost savings, much less detect pilferage.

merely monitoring charging at work doesnt remove pilfering, how can you determine the correct use of the fuel .

it isnt done today with petrol that companies provide, most just allow " private motoring "

Why would people do this anyway? Since electricity is 6-12 times cheaper than petrol and home V2G systems cost several thousand how would it ever be worth it?

In some areas in the USA, some utility companies are running trials. Not only do you get a monthly fee, but you also get a very high rate of pay per kWh (and all systems installed for free)

So good luck to anyone in those trials who manages to load their car up for free first. Having your cake and eating it

Could make an expensive EV with a large battery pay for itself!
Charge up to full every day, and then take out all the excess energy at home using V2G and get paid for it.
Brilliant, where do I sign up!

unkel

Yeah I'd love to have that set up. Not so much for any money savings, but more that I feel it is the way forward with loading big grid attached batteries (EVs) with cheap renewables, to partly use that for peak times when it is expensive and environmentally unfriendly to produce electricity.

the assumption being that work charging is cheaper them domestic electricity

I think not based on what I,m hearing from installers of work place charging

well it's free for me

unkel

Free public charging - check
Free work charging - check
Free home charging - check

Don't count on that for much longer.
I expect charging to come in, punitive like the 2015 rates, in Q1 2018.

unkel

I've free home charging now for the next year

I doubt very much that there will be punitive public charging rates as soon as Q1 2018. Nobody will benefit from that. Maybe we'll hear some answers later today...

Well there was a 6 month timeframe set out in the CRU decision.

unkel

6 month in the CRU = 6 years in real life

I guess we'll see but any of the ESB reps I've spoken to privately admit strongly there will be no charging in 2017, they emphasised the "in 2017" part

correct , Ive been told the same. I think well see proposed rates before the end of the year and actual implementation by q1 2018 , ( FCP will be the first , the original ESB plan envisaged free SCP charging for a further year )

How did you get that?

If street charging costs more than home economy 7,@ 8p/ kwhr, they can keep them with the apalliing service record, be careful​ ESB/ NIE. Vote with your volt.?
