New batteries come in 2014: 800 Wh / kg

Renewable energies except solar electric or thermal (seeforums dedicated below): wind turbines, energy from the sea, hydraulic and hydroelectricity, biomass, biogas, deep geothermal energy ...

If you buy LiIon cells individually, it is around 1 € / Wh, retail price. 8 € for a good 18650 "bar" which contains 8 Wh.

We can assume that in quantity it will be much cheaper, maybe 3-4 € per Wh ...

I guess the reporter added 2 or 3 zeros somewhere, as usual : Mrgreen:

I have 95 Lithium iron phosphate cells which represent 17300Wh
for a budget of around 5300 € (it depends on the € / $ course).

Or the Wh at 0.30 € returned to France
Price negotiated by an individual, your servant. : Arrowl:

These batteries will replace 12000Wh of NiCd batteries which weighed 260kg.

The new pack will therefore make almost 50% of additional capacity (gain in autonomy), weighs only 180kg (gain in nervousness and payload) and it occupies 25% of volume in less is still 5800Wh of available volume.

I chose a "standard" and "safe" technology, I am not looking for absolute performance but the best reliability price ratio.

The future will tell if I'm right.
I am sure of one thing, driving steaming is a punishment when you have tasted the electric and the progress it represents.

I do not have this claim. :?
I only make compromises in relation to my limited means.

I reflect and try to change, to evolve.
Ce forum allowed me to move forward, to save time.
I drove on diesel, then on LPG, now on electricity.
I thus avoided pantone, frit oil and a few other experiments which were of no interest to me given my use of the automobile. I hope to embark on other research, such as stop & start (more suited to my short journeys) which shows that manufacturers could but did not want cars to consume less.

I try to practice the "happy sobriety" dear to Pierre RABHI.

The process is similar for home, food, leisure, my militant commitments.
Trying to do things that make sense, that of being part of a sustainable, sustainable process, if not being redemptive ...

My last intervention was BEFORE driving lithium.
The implementation was long and the development with the quality criteria that I want will still take a lot of time ...

So I have been driving for 2 months with my Lithium Iron Phosphate batteries and already more than 2500km traveled.
The behavior of the car is transfigured, it is more nervous, more powerful, consumes 30% less electricity and its autonomy has almost doubled (I have already done 135km on a single charge, driving very energetically).
It is still too early for a real assessment, but the result is very encouraging. : Mrgreen:

The mass energy density of these batteries is around 100Wh / kg

The prospect of having 800Wh / kg batteries is therefore more than exciting, even if for me this is not of short-term interest, the autonomy which I have today comfortably widens the field of use of 'a car that managed to cover 18.000km / year in our hands ...

citro your information is precious

you have already shown that the good old NiCd are sufficient to be useful

you now show that the lithium iron phosphate available at reasonable prices are even better

so those who misinform with wacky futuristic stuff only confuse everything, as if the goal was to delay the use of what is currently possible

and the current car makers are branquignol not even able to do with what is readily available

Finally when we see the level of Peugeot ads we understand that putting a battery and an electric motor in a car is too difficult ...

there are also lobbies that block from behind ...

I think that some good people must become schizophrenic ...

because clearly they do not have the control of the specifications of the vehicles, which are on the plan of the powertrain, completely subjected to thermal, therefore to petroleum and the related taxes.

On the other hand, the vehicles are getting too big ... My R19 appears small in front of the latest Twingo models, it's delirious.

The wheels are out of proportion, and the SCx explode. After it is said that the engines have a better performance .... to develop 50% more power, overall it consumes more than the old well designed.

All of this is true, but I owe it largely to this forum and to the reflections it provoked, then to my wife who asked me to put it into practice ... :?
Without you, without her, without the forum vehiculeselctriques.fr, I would have stayed in the waiting, like all those who tell me, even today, it's too expensive, we are waiting for it to drop ...
1 month after the madam took possession of her electric 106, a good handful of years ago, I was feverishly looking to get one. While I had spent years hesitating, listening to the speech of the few users, muffled by the deafening hubbub of the detractors who spoke without knowing ...

That said, the path is not without difficulties, it requires to acquire skills and to be lucky, and on this side, I am doing much better than our friend Macro, whom I salute here for his tenacity.

Madame will soon take possession of a Volkswagen e-up, which represents a heavy investment and a working tool for her. For me, this represents new challenges and fights to "free access to the socket", constrained by new "standards" (not innocent at all).
Our dear nlc works there with great talent and convincing solutions.

We all get things done, and participate in the dynamics of change. 8)

yes, well seen Citro ...

But are you going to end up opening a garage in VE? :P
