Request for information: 12kW electric motor on battery

[I Citro]

You leave the batteries connected and you use the gene in parralel directly on the batteries, there is no break and no reason that it does not work!

That's exactly what I plan to experiment ... When I have time.

My problem concerns the group I want a power between 7 and 12 kW, able to provide 220V single phase and possibly three-phase.
The idea is to be able to modify the group to deliver a properly adjusted DC voltage adjustable according to the type of vehicle to be equipped (between 120 and 140V for my 106 but between 162 and 190V for other models).

I would only use this group very occasionally in cars because it is useless on more than 95% of my trips. I wish it is light and compact.
This group will be used to provide energy to my home in case of power outage as we fear more and more each year since the privatization of EDF (Network cut that would deprive me of my mobility electric).

I bought a generator lastly for use on site, it is a 6 kwatts gasoline and the output power is 240 volts with neutral so 2 times 120 volts to neutral!

By connecting according to this small diagram it will give close to 140 volts DC:


Of course other more efficient diode configurations may be suitable, this diagram is only an example!

an example of 400 Gel 1000 battery discharges 6V
20 should be 600Kilos and 6000 € and 5H discharge 35 A and 100A in 1h about and 400cycles max !!!
and at random between 10000 and 40000Km (between 25 and 100km per load ???)
and price per km from the only higher battery already than the petrol or diesel engine only (at 1 10 Km) !!!!!!
and we must add the price of diesel consumed more by trimming a trailer of 600Kilos as a pan !! !

A Prius will come back cheaper soon, and you're sure it will roll ... Confused
I do not say that to discourage you but explain that you want to make an airbus and put a moped engine ... You will have the budget of an airbus and the performance of a wheelchair for disabled.

Fun !!

and it is better a diode bridge and the dissipation radiator costs more than power diodes !!!

The lifetime of batteries guaranteed with their price implies that the price of the battery purchased (without the price of energy and more) at Km is more expensive than conventional fuels!

This reality plumbs the electric car !!!!

And it should go out !!!

Well, that's not the reality ...
In my case, the actual price of my batteries is less than 2 years of driving (we will travel between 12.000 and 17.000km per year per car), and their longevity may exceed 10 years if we respect the instructions.
On my 106, we can expect 150.000km on a set of batteries.
Regarding the cost of energy, it varies depending on the type of subscription, simple price, I was 2,40 € / 100km last year that I converted 2,4l / 100km diesel 1,00 € / liter.
This year, I have a double EDF fare and I mainly charge night fare at half price, the price of fuel has, for its part not really dropped ...

Oh by the way, if manufacturers like Renault want to get us into the electric car and make it as expensive to use as the thermal car, it is precisely that they have fat to be made (on the car, on batteries and on energy). think about it.

The batteries of this first link are replicas of the excellent Sonnensheim batteries that fitted the Volta electric cars (I brought 16 to recycling recently).
Do not even try to put that in an AX or 106, you will be overloaded.

For a similar budget, or even lower, there are offers lithium. But we do not have enough perspective yet.

And LiFePO4 batteries?
Americans seem to use this battery technology quite a bit in their "home made" electric car projects.

Very informative :

And it should go out !!!
How come out, for 10ans of battery and at least 120000 to 170000Km in 10ans with the same battery for how many refills: 2000 to 4000 times on which batteries ?????? And how precisely does one get 10 times more than what the battery manufacturer says ???
I think lamure will be happy to learn from this success !!
This changes the balance of the electric car !!!

Very good question !!
Very good for discounted models, planes, etc .., bike
A big progress !!!

Just respect the battery operating instructions.
