Using wheelchair's battery as power station in WAR

[Aghajoon]

Hi
as you've probably heard there is going to be a big beautiful war (Trump's saying) in Iran
I have an ancient Permobil c300
is it possible to somehow use it's battery as a power station to power some vital things like my inflatable mattres or my laptop? I can't afford additional batteries
I'm thinking maybe I could use a hybrid charge controler/invertor and connect it directly to the batteries (not the wheelchair joystick's port)
this way I'd also be able to charge batteries via sollar pannels if they blow up power plants
my concern is if it's going to harm/fry wheelchair's electronic? I mean, hybrid charge controler is going to charge at ~28V (connected directly to the batteries). I know very little about Electronics

That's what your typical mobility charger charges at. As long as you connect directly to your batteries, you're fine.

Not sure what exactly you are wanting to do.

One of the reasons that I have the same grey 50A andersons on every damned thing is so that I have countless options. My electric bed, powertools, 12 and 24V AC inverters (to get 240V) all my solar panels, grid tie inverters, soalar chargers, and even my van are connectable! My chairs - all 5 of them - have either lead or lithium batteries that can run my house, charge one chair from the others (all my PL8s have andersons on in and out connectors) and more.

So I can run my van engine to charge everything! I have a long cable that connects to its Anderson and into the house. That can provide 100A.
Or I can start the van from external battery... And that van itself has solar on the roof.
I can charge 12, or 24V or lithium batteries (PL8) or run anything like my house, heating, etc all from battery, solar, van, chair etc.
EVERYTHING can plug into everything else. A powerchair can run the central heating. Another chair can run my bed, air conditioner for heat, or lights.
Solar inverters can charge he chairs during daytime. Tools, AC inverters for AC powered things, like fridge, house, or DC powered things like chargers, chairs, beds, etc. Its all about OPTIONS!!

yes voltage is the same and there would be no problem
what about courent direction? I mean when wheelchair charges the battery, electericity flows from wheelchair's board to batteries. now it flows from hybrid charge controler to batteries and the board. is that ok?

What country are you in? Iran?

The war in iran will last about 15 mins. The iranian supreme guard are already running away, the US wont even need to do anything. They are already beaten by the population. They know that they are beat. If theres a war at all, it will last about 3 minutes. Then you will all finally be free again. As long as you dont allow any more muslim extreminst nutters to abuse and torture you.

that's exactly what I need to do.power my devices with my wheelchair 's batteries
EPEVER® UP2000-HM6022 Inverter Charger let me power my devices with it's invertor and it's capable to charge my batteries with it's mppt charger via solar or 220v AC. but I'm afraid If I connect it to my batteries and blow up wheelchair's board because both wheelchair and EPEVER are connected to batteries at the same time

the red battery would be my wheelchair

What country are you in? Iran?

yes

The war in iran will last about 15 mins. The iranian supreme guard are already running away, they are stupid, weak, and completely outgunned! And they are all mouth and no trousers. The US wont even need to do anything. They are already beaten by the population. They know that they are beat. If theres a war at all, it will last about 3 minutes. Then you will all finally be free again soon enough. As long as you dont then allow any more muslim extreminst nutters to abuse and torture you.

The reason a battery charges is because the voltage from the charger is HIGHER by a few tenths of a volt than the battery. So it flows in to the battery untill these match. Then its full.
The reason the battery can run things is because you apply a load (a resistance) which tries to pull the voltage down.

You dont need a fancy seperate device. Inverter charger/solar inverter/AC out.

You can connect a solar charge (simple, cheap) straight to the chairs BATTERY.
You can present a load to these same batteries either while charging or when not charging, seperately by using a simple cheap AC inverter to get 240V.

The chairs controller or electronics are not involved and so just dont care.

However you are not realistic. A chairs battery is about 1kwh. If its full. Thats WAY too small. You need around 10x this. And you will need around 3 to 4KW of solar panels to keep up. In summer. In winter forget it.

[Aghajoon]

That's the part that I don't understand.
In your scenario the mppt charger and the wheelchair itself are connected to the batteries at the same time? or you mean I “have to” isolate them with Anderson connectors ?
my concern is when I'm trying to charge the batteries with mppt charger and the wheelchair is connected to the battery also, I hurt the wheelchair board

[Burgerman]

No.
You can connect a CHARGER. Solar or AC or whatever...
You can connect an AC inverter to run a fridge, charge a different chair, run your TV...
The powerchairs controller is not involved and does not care!
Its all perfectly fine connected and working at the same time. All 3. Charger. AC Inverter. Chairs controller. and you can add a solar panel, or whatever you want all at the same time...

my concern is when I'm trying to charge the batteries with mppt charger and the wheelchair is connected to the battery also, I hurt the wheelchair board

But you charge it at night anyway right? That doesent hurt the wheelchairs board does it? Why would you think an MPPT charger is any different??? Its not!
However your chairs battery lacks the Ah capacity to be very useful to run anything of consequence for long.

[slomobile]

What you propose should work fine. But like BM said, your battery size is limited compared to all the things you might want to run. So your runtime will be short if you run them all.

There are ways to keep the things you absolutely need running longer. Prioritize.

If you can get a second set of batteries, or even just a single 12v battery, that might serve you better than the fancy hybrid inverter if you cannot afford both. 12v chargers(automotive), inverters, DC-DC converters are usually cheaper and easier to find due to the automotive market and easier to borrow. You can just keep all the separate pieces connected together at the 12v battery and it will work similar to the hybrid unit, just not as automatic. Buy or make a 12v lighter socket extension cord so you can recharge your 12v battery from any running vehicle willing to stop for a few minutes.

Last resort, you can charge your chair using its regular AC charger running from a 12v inverter on a 12v battery you charged earlier. That is VERY inefficient, but I've had to do it more times than I care to admit. Solar charging a chair means you need to remain stationary all day. I prefer to use my chair all day while solar charges a stationary paralleled pair of group 24 batteries. That gives me a 12v large capacity advantage but still serves as a backup 24v set for the chair if I'm willing to swap. If you make a set of series/parallel plugs like BM shows, you can parallel the 2 sets to put some charge into your chair overnight, but it will not fill up your chair. For that you need something to raise the voltage a bit higher. A DC-DC will raise the charging voltage, but if your stationary batteries and mobile batteries are the same capacity, AND your mobile batteries are fully dead, there wont be enough energy in the stationary batteries to full charge the mobile set. The stationary set will get cycled deeper than the mobile set unless the stationary set has even higher capacity.

Avoid running the inverter unless you really need to run something that cant be powered DC-DC and draws at least 20% of the inverter rated power. While it is running, it will produce a little heat. Power supply bricks for your laptop etc can be put under your blanket to keep you warm if needed. If drawing less than about 20% from the inverter, and it is not powered by your chair, also use it to charge up things with internal batteries like flashlights, phone, laptop because the inverter burns up quiescent current any time it is on. Try to keep as much energy in your chair batteries as you can in case you need to move.

When camping I use DC-DC power bricks for my computer and CPAP that can run on either 12v or 24v, whichever is available. If I run the CPAP all night on the chair with humidifier on, I have about 25% less range in the chair the next day. Barely noticeable if I turn off the humidifier.

For whatever its worth, I think most American citizens oppose war with Iran. In a few places in America it feels as if our federal government is already at war with us, and behaving the way they criticize Iran for. https://youtu.be/Orjbwv8H9zM

Trump is doing what he was democratically elected to do. You seem to be listening to the extreme left and the mainstream media who are complicit in their trump derangement syndrome.

The US wont be at war with Iran. They will be at war wth the extremist islamic iranian guard that took over the once enlightened modern western style country of moderate muslims, xstians, and sane people (athiests) by force 45 years back. They have brutalised and forced the population to obey, and treated them the same way they would treat you. And have wanted freedom ever since. On top of that islamic guard rulers have many terrorists groups, all as a proxy, all funded and have weapons provided by the same extremist regime.

The people of iran are finally on the streets and being murdered by the thousand and tortured (nothing new) for months. In a desperate attempt to get rid of them. They WANT the USA which is really the worlds policeman to help them. They are desperate right now. That way the whole middle east will be a better safer place. Terrorists will die from lack of support and funding. Israel will also be safer as they hate them and want to wipe them out. And american interests will be protected too.
So they (iranian population), and most of the sane parts of the world are WAITING for the israel/US help to aid in/get rid of this monsterous regime and free the iranian people.

Most americans dont have a clue about the rest of the world. I have seen your news channels and spoken to people across the whole east coast and the lower states as far as texas. To say that the US and its news coverage is ignorant of the world and world politics is pretty true compared to an average european. Most of your news is almost completely US and left biased. Ours is left biased too, and chooses to ignore all the subjects and stories that dont fit its agenda too. I dont watch the lame stream media for decades now.

[Burgerman]

Something else to consider.

I have 3000 watts of solar here. Today, its white cloud. It is making 38 watts... That wont run he fridge.
And remember nothing made at all before a few hours after daylight, and a few hours before dark, as sun too low in sky.

In summer at noon, if its a sunny day, it makes 2500 watts on occasion. As the panels warm up they make less. Mostly it never reaches that figure for more than a few mins. It spends most of the day with the sun at less than the perfect angle too so a lot less.
So it can make anything from 100 watts approx, to 2500 peak for much of the summer day. Most of the day its 200 or 300 or maybe 500 watts.
In winter it makes barely anything. Some days it wont run a light bulb.

So the idea of having solar for power is not good. Even with 3000 watts of panels. Because whie you MIGHT get 2.5k watts for an hour or two a day in summer its going to be a LOT less (to nothing at all sometimes) in winter.

So to work OFF GRID on solar alone I would want maybe 20kw of solar panels. And at least 30 kilowatt hours worth of battery. Enough for 3 days if fully charged and careful controlled use. (if you can keep it below 10kwh per day.

In winter my 3000 watts of solar would not keep a powerchair topped up in normal use. It might most days in spring and autumn. It will in summer. With lots of extra unneeded power too for other things.

I sugest instead making a HUGE LiFePO4 battery pack. As big as you can make it. And charge it when there IS power. Then use this to power everything. And a backup generator to charge them if required.

And now the islamic taliban government running Afganistan are attacking and declared war on pakistan own extremist islamic government as a part of the caliphate (the muslim extremists drive to make the world islamic by death or worse) because they are not extreme enough... And using all the US weapons that the moronic biden left behind).

So I am watching two extremist muslim islamic governments armies both killing each other with guns and missiles and aircraft etc. Shouting "alans snackbar" at each other repeatedly. As usual their god is on both sides
Just understand that these nutty extremists will come after you when it can and it wants you dead if you are not a muslim. They beleive that the world is theirs. And you are the enemy. Thats what their book tells them and they are all brainwashed to death quite literally. Its why your world trade centre is no longer there.

And as a part of that caliphate they also want israel wiped out. Right now Iran is sending hundreds of missiles into them. Watching that live too. They are also sending missiles into many other places that are not "islamic enough" that are muslim countries as I type.

[Burgerman]

And now all the brutal extremist mental religous leaders and the "supreme" leader of this 45 year hell are all dead. Oh what a shame.

There is wild partying in the streets of tehran.

[Superchunk]

well... that was a quick "war"

[Burgerman]

Well its not done yet. Months... Days? The regime is huge, controlling, they are not gone yet. Now is the peoples chance to take charge. Will they?

[Burgerman]

Actually it will never be done. Until that awful religion is defeated. Thats what makes them do it. They are driven to hate you. To convert or murder you. And to take over the world. They dont do logic. They also hate the west, hate capitalism so are great bedfellows for the liberal left maniacs that are also spreading across the world. Most of those are simply dumb, ignorant of reality. So much so that we recently had a "gays for palestine" march in london. They just dont seem to get that they would be thrown off a roof... Ignorance reigns supreme on the left!

[slomobile]

US constitution gives only Congress the authority to declare war. It was illegal, plain and simple.

[Burgerman]

Well illegal or not it was essential. Do you really want a bunch of religous nutters and sworn enemies of the west (+anyone that isnt muslim) hell bent on destruction of israel to wipe it out and then the rest of the west to follow to have nuclear weapons? Just to begin with. Thats ignoring all the other issues.

They really are crazy and they love death. The IRLG are a mntalist terrorist death cult with clearly stated aims to kill YOU. Their own lives, yours, and anyone not muslim are their sworn enemies. Th same islamic nutters that took down your world trade centre. If they had atom bombs they WILL use them. They cannot be reasoned with. Who cares if its "legal" or not. Some times you just need the minerals to just do the right thing. Its a damned good job trump is in power. Because without him we would all be screwed.
