Random EV thoughts.....

That's very suspect, when you read down to the details it seems it's the r600 for that price not the r4000.

Bit interesting how you can see weight is really a limiting factor with those portable batteries

That's 45kg for approximately 3kWh of power

A 48V battery case for home solar loaded with 304Ah cells should give over 13kWh of capacity

However they would typically weigh over 80kg, and when you add an inverter, frame and casing you're likely looking at over 100kg

You could probably get away with a 4 wheel cart on fairly flat surfaces, however any kind of lumpy terrain will make it impractical

An electric motor to assist the cart would help, but at this point we're really stretching the definition of portable. Might as well just drive a golf cart around with an inverter 😁

I probably shouldn't have posted all that here but anyway.

The above is just one example, 24 v 100 Ah is 2.4 kwh

Need a reputable source with E.U stock.

That would be good as an internet UPS alright, should keep it going and a laptop topped up for a couple of hrs or more.

Only thing is that to power the well I'd need a lot more juice, and the septic tank this is where I believe a generator is best. If only the car charger could give power back to the grid and you could get a generator/battery to connect to the type II plug…..

powerwall type batteries are still a mad price especially when you factor in installation and inverter , I don't know if any of those batteries include inverter ?

I do use a 600 watt pure sinewave inverter off a car battery which is handy for keeping the internet running so that's a cheap way of doing it if a bit messy but it works and cheap. I just have to remember to keep it topped up once a month that would give me more storage than the R600 even by not running the battery down all the way which is bad for lead acid. It's not a deep cycle battery.

a 12v 100 Ah LiFeP04 would keep things going a lot more though and I could put a 1.5 Kw inverter on it to run the well and septic tank pumps, although, they have a very high starting current load.

Amnyone have the car set up as a battery source for when the power goes down?. Have been reading a bit about vehicle to house storage after seeing a company on nationwide using old ev bateries for pv storage

When I had the id3 I used a 600 watt pure sinewave inverter directly off the battery terminals, the ignition had to be on or the cars own inverter wouldn't have kept the 12v battery topped up, it worked great except I had to go out and turn the car back on, every 30 mins it would shut off.

The id3 77 Kwh has bidirectional charging but a bidirectional home charger is incredibly expensive at the moment. Last time I checked it was around 6000 pounds sterling, there is a lot more involved and needs a DC- AC converter to power the house. It's going to be several years before they come down in price for obvious reasons.

Currently the only way to do it is if your car has V2L onboard through an inverter and you just run an extension lead into the house

There's chargers coming that can use the car as a battery for the house or sell it to the grid, but the certification process is likely a bit stricter and there doesn't seem to be a preferred way of implementing it

How does that work , do they sell a compatible EVSE ?

So a proper v2h or v2g system acts like a solar inverter and just tops up the house supply and if the house takes more then the house pulls from the grid. In the case of a power cut you need a system similar to a solar home battery system that works during a power cut.

The technology for all this exists today and some say some of ID range cars have the capability to do this already. Indeed inverters that an do this are on every house that has solar panels.

The Irish regulations are slightly different than other countries and the car manufacturers want to get a cut of the money or have extra fees to enable this option. They will claim it's to do with battery warranty and potentially more battery warranty claims if everyone is powering their house from the cars battery and putting in more charge discharge cycles. The grid operators don't want competition

Hobbyists have already gotten this to work. One system is a manual change over of small loads such as powering lights and sockets from the car in the evening and charging car for free at work or on low night rate. This can be automated.

Other DIY options tap into the high voltage battery and use a solar inverter designed to connect to a home battery, not ideal but similar to using an old EV battery mounted to the house wall to power the home hit instead keeping it in the car. Again messy and risky

Beware the normal V2L CANNOT and Should not be connected to your home fuse board without mechanical and electrical isolation such as needed for an automatic switch over backup generator.

The future seems to be AC coupled systems with the inverter in the car working like a solar inverter, that makes the home charger relatively straight forward but no home chargers that I know even are capable, so it would mean at least changing your home charger, along with at least a car software update. The home charger would probably need extra wiring and safety systems like home solar warning stickers on the ESB meter box, fire man cutoff switches etc.

There's already a chademo standard for this. Hydrogen cars from Japan have it already fitted.

Wouldn't it be great if all chargers had debit card readers on them, so you could use that secure payment method that works everywhere except taxis at 1am

Do you think they managed to build that canopy for less than €336000?

They realise they have to do something. Soon nobody wants to buy their stinky petrol and diesel anymore

Bit of an interesting aside, you can generally see a bit of a difference in attitude between European oil companies and others

Shell, Total, Circle K: This EV thing is taking off, we should probably invest in some charging infrastructure to stay on top of the market

Exxon, Texaco: This EV thing is taking off, how much are we going to have to spend on lobbying to prevent it going further

Not saying the European oil companies are good, being slightly less morally bankrupt than the competition isn't much of a hurdle.

Just think it's interesting to see the difference in attitude over where the future is
