Charge from a portable battery

[mg4]

I fit in the group of people that cannot install their own charger. I own my house, but it's a part of a home owners association in the Netherlands in which my neighbors are afraid of EVs charging, catching on fire and burning them alive, what to say about media.

Also, running a cable is forbidden, both under ground or under those kable protectors you see at concerts.

So my only way to get my "free" solar electricity to my car is either long range wireless ? or what i just got an idea yesterday was to use a chinky 5-10 kw home battery. Basically put that and whatever else needed on some base with wheels. Because strangely enough, charging home batteries is seen differently than charging car batteries, no one seems to mind me charging a huge home battery up, wheeling it outside of my complex and charging my car there.

At some point i also question if this is a problem worth solving, but i am curious if anyone has any advice, experience or caution to share.

That sounds like an ingenious solution. I'm presuming you secure the battery so it cannot be stolen?

It is a shame that you aren't allowed to just plug in!

The downside is that you'll have probably around 10% losses from the extra conversions. But the battery could be used for other things as well.

My concern about doing this would be that the unit would be stolen if you leave it alone by the car.

One response might be to put the battery unit in the car with the window open a crack for the cable. But that might leave your car more vulnerable as well.

I suspect that wheeling the heavy battery all the time will get old very quickly.

Maybe the neighbours will see this nonsense and realise how stupid they are being!

That's completely bonkers.

Sounds like an expensive solution. Bjorn Nyland has used ECO Flow units to add a little extra when he has run the car battery out. Perhaps a a few of those would work, lighter to carry and you could be charging 1 (or more units) while the others are charging the car.

Charging, discharging and inverting an intermediate battery will introduce more than 10% losses, plus you'll be cycling (and degrading) two batteries, so your solar won't be free anymore.

Surely there are two solutions; my preferred would be to move house as I couldn't possibly live alongside people that stupid. The other is to ignore their 'rules' and charge your car normally whilst waiting for natural selection to take care of said morons.

I'd go along with the latter solution!!

Firstly, If your property has solar panels and you can charge your battery from there for free then that overcomes one problem, if it does not then to try and charge that 5-10 kW battery from panels on your trolley or "portable panels" in your property would take a long time as the area required would be vast compared to the trolley size even with todays efficient solar panels, this would probably take several days to charge.
Secondly, With only a max of 10 kW to deploy to the car with the charging losses, as I assume this will be a 220V, 2kW charge you'd get a maximum of about 8 kW into the car, which would translate to about 50km range increase. Depending on your daily usage this may or may not actually be enough to cover your daily drive.
So I could see you having to do this process several times a week to make any real impact on the car's charge level. For the amount you are going to have to spend for the setup and the amount of charge you'll achieve I can't see the figures adding up. Its a nice idea to be able to harvest all that solar energy and deploy it to the car, and technically a good idea but there is going to be many issues to solve along the way to make it viable.

Carrying that extra weight in the boot for an emergency charge is going to affect your range. Much better to pay attention to the GOM and charge before it gets too low.

Modern EVs and charging systems are safer than even from 1 year ago.
Can you call a meeting of all the residents, get some expert Person +/- Fireservice who can make your case technically as well as your own input to get this changed.
I live in a Conservation Area in the UK and had some issues but managed to get them resolved

Much negativity comes from incorrect assumptions. Range anxiety being a prime example. If your vehicle can actually do 250 miles and you rarely do more than 200 miles in one round trip then the range is not an issue. If you do more then you need to do a little planning.

I am planning on picking this up, sadly will be legally, but it makes no sense to dump time and effort into it unless i can actually win this. It is that upsurd, but if i do, i plan to open up the legal process somewhere public for the other 30% of people living in a housing association in the Netherlands.

As for range, i just completed over 7000km with two small kids and my wife, where a large part of it was in the south Balkan countries and i neber had range anxiety or charging issues, so it really is all media and misinformation issue.

What a shame that it would come to this.

People should want the option to charge cars. I thought NL was one of the more advanced countries when it comes to EV adoption.

New flats near me have EV chargers in the car park. No idea if they get cheap electricity, but even if it isn't particularly cheap it is convenient to charge overnight before a journey.

Indeed, and on paper the NL does a lot, like give subsidies, encourage companies to place street level chargers and dc chargers.

But, it protecs the companies, not it's citizens. Hence you can charge on my street for 33 euro cents per kwh on 2 spots by one company or 89 euro cents per kwh plus some cents per hour plus some cents per session by another company.

Or someone can block me from using my 'free' solar electricity and make me charge on street. And guess which spots are available then.

New flats near me have EV chargers in the car park. No idea if they get cheap electricity, but even if it isn't particularly cheap it is convenient to charge overnight before a journey.

As above, sometimes the prices are cheaper at dc chargers. I pay 39 euro cents on an Ionity dc charger or almost a euro on a ac charger on street.

i got a notification about a reply with a link to a battery, but seems deleted.Is it possible to get it as an private message to my user here?
