Driving an electric car every day




by phil59 » 25/07/21, 15:23

THANK YOU FOR NOT RESPONDING AT THIS TIME, IN THE WRITING PROCESS.

Here, we will not discuss the pros or cons, driving an EV (electric vehicle).

I have been driving an EV since 2012-2013, and an EV since 2018. (I mean my wife and myself)

The first point today to drive an EV is to be able to charge at home.

Having access, in order to be able to charge at home, is practically essential today. Tomorrow, solutions will exist, but not yet today outside the "home", or so rare, that it will remain exceptional cases.
We will treat here only the cases of sir, Madam everyone.

The second point, will undoubtedly be, how many km you make every day, in return.

An average consumption is 15 kWh per 100 km (today, I did less than 13 over 170 km).

Take the autonomy of an EV, divide it by 2, and if it sticks roughly, for every day, it will be possible, without worries, and this in 10 years.
We will consider use over 10 years, with today's data ....

Many people drive well under 60 km per day, so an EV, with 120k of range, should be fine, depending on how fast you are going.

Driving at 130 km / h with an EV will consume a lot more than 80-90, because the efficiency of the electric motor is practically the same at 10 km / h, as at 130 km / h, unlike a thermal vehicle, which itself, when you get to a certain speed, like 2000 rpm, you start to improve, so you consume a little more at 130, than at 90, but like 25% more.

In EV, between 80 and 130, we will say, exaggeratingly, that you double the consumption.

This is to understand a little the "why of the how". I try to keep it simple and colorful ....

There are several options for charging when you get home.

The simplest, the original 220V socket.

It charges the EV to about 2 kWh, or in 8 hours, you will give enough to do 100 km.

There is also, in just as simple, the green-up plug, which is a plug adapted to the power which lasts a long time.
Namely, on a standard socket, it supports 10 / 16A, that is to say 10A, or 2000W (rounded, otherwise 2300), in perpetuity, on 16A, (3500W) for 30 minutes.
The green up supports 3500W to perpetuity.

In 10 hours, you put more than 30 kWh in the car. What to do about 200 km.

If you can charge at work, that's good, but not to rely on it 100%, you have to be autonomous, or have enough to charge on the road, in recovery.

Home terminals, wallbox.

The standard, currently, is the T2 socket.
You can have a 7 kW terminal, but that also supposes having a subscription, type EDF, greater than 7 kW, type 9, mini, from mini.
Currently, in France, a lot of subscription in 6 or 9 Kw.

Charging in 7, allows you, depending on the car, to provide enough to do almost 500 km in 10 hours (if the car has the battery).

Most of EV, can charge up to 7 kW on T2 socket.

T2 sockets are the most easily found on public charging stations.

I complete thereafter.

This is what a T2 socket looks like.

It can generally supply between 3.5 kW and 43 Kw, in AC, alternating current.

There "existed" the chademo,

which charged with direct current for example the leaves, often in 50 kW, but some went up to 100 kW.
In addition, it was a bi-directional system, which emitted, or received "the juice".
"Japanese" system.

Today, there is also the CCS or "European" combo.

prize-combo.jpg (11.67 KiB) Viewed 2046 times


Currently, we find up to 350 kW .... Both an AC part, and a large DC part (continuous).
Note that the "upper" part of the socket is a T2 socket


Currently, you need an EV with at least one T2 plug, and if possible a combo or CCS for long journeys.

Now, do I have compatible sockets near my home?

Currently the chargemap site is the most complete, both for France and outside of France

The Tesla have the particularity, in general, of being able, with options, to charge on any type of terminal, practically ....


So much for the generalities.

Is it all complicated? yes, but no actually.

Often, you will have at least "T2", and sometimes a CCS.

All these terminals are used, and are often only used for journeys outside your range of action, that is to say, most often, if you exceed 75 km from home, at the strict minimum, depending on your car .

The "new EVs all have at least 200 km of range (for almost all).

Apart from that, I arrive at a terminal, I plug in?

Yes, if the terminal has a credit card reader, no worries, otherwise, you must have a charging card (s).
For the majority, but, for example, where I work, we have installed T2 terminals, you arrive, you plug in, and that's it, and it's free ...

Free, I am not for, because it necessarily generates overflows, cars that block the day or a terminal, instead of an hour for example.

Often, depending on the tariffs, we arrive at 20 cts per kW, while at home, all taxes, etc., it comes back in full hour to 16 cts.

I have an ion (16 kWh) at the end of 2012, at the beginning of 2013. About 100 km of autonomy.

Madame, between 2015 and 2018, had an ion (14.5 kWh).

In 2018, madam, had a zoe, ZE40, 41 kWh. (250 km autonomy)

In 2021, a kona, 64 kWh, approximately 4 km of autonomy.

Autonomy decreases with age, and km.

Currently with the ion of 2012, I lost less than 20% of autonomy, really. (around 17%). THE car has within 115 km. They are used every working day.
These are quite old cells, now we are doing better.

Not being able to edit my posts, if someone "of authority" could merge my posts, and remove the "I complete" and not respond ...

The question is the same for oil, when oil is going to flare up! It is exactly the same thing, if it is only for oil, it will undoubtedly happen, well before.

Now the juice can almost be done alone, with photovoltaic panels ....

Currently, I have recovered some 200Wp panels from OCCAZ, and put micro-inverters on them, just to cover the background noise of the house.

Profitability in 3 years.

The goal will be to put a lot more panels, and sometimes load the car on them, and sometimes have the car power the house.

But this is out, driving in EV every day with the bps that it can cause ....

Thank you for this recap.
Your last post partially answers the question I was going to ask you, that of the loss of autonomy with age, the number of cycles, or mileage.
In fact, I plan to switch to electric for my next (and maybe last ....) vehicle in 3 or 4 years, but I drive relatively little (my Clio is 11 years old and 90000 km). As I keep (historically) my vehicles generally more than 10 years, I wonder about the autonomy at this time.
Do you know one or more studies that answer this question of the respective influence of age, the number of charge cycles or the distance traveled?
In other words in my case, can a low annual mileage allow me to consider a greatly increased lifespan even if I use it (and recharge) a few tens of km on average per day.

The question is the same for oil, when oil is going to flare up! It is exactly the same thing, if it is only for oil, it will undoubtedly happen, well before.
I'm not saying one is better or worse than the other. but currently the price of oil is high only because of taxes, taxes that will have to be recovered elsewhere from the goose that lays the golden eggs that motorists are once again. Then put the same petroleum taxes on electricity and do your accounts.
The other aspect is that of the monopoly which until now was on thermal and which will be transferred to electric if, according to forecasts, thermal will be eliminated. And as they will not make 2 prices for our beautiful doe eyes ... zou the blow of bamboo behind the ears, but there will remain the eyes to cry!
so don't think in terms of today, but in terms of the future!
PS: the bonuses will not last with such a rapid transition because an industrialization does not happen on the snap of a finger ... politics by demagoguery

demagogy
feminine noun
Politics by which one flatters the masses to gain and exploit their adhesion.

There are some basic rules to follow if you want to keep your cells (battery) in good condition for a long time. It's not essential, but it helps.

Do not charge your EV to 100% if you are not going to be driving with it during the day.

If it remains immobilized for a long time, ensure that you only have about 50% of the battery charge (for the batteries currently found in cars), but especially not at 0 ....

For everyday, try to ride roughly in the 50% to 80% battery range, and only charge to 100% once a month, for example, like going down to 20%, once a month (idea + -).

On my kona, for example, I can put a parameter, so as not to exceed 80, or 90% of maximum load.

If you are at 65%, for example, do not hesitate to load up to 80%, "bottle-feeding" is recommended.

Loads up to 11 kW on terminals do not twist the batteries. That fast loads, like 50 kW or more, are not at the top either.

But all this is only likely to play on 1-10% of total autonomy, battery life.

On the other hand, charging from time to time in rapid can be beneficial for the battery.

Did I do all of this with the ion? Well no, at the start I didn't know, and I continue to charge 100% every day ....

With the kona, I am a little more careful.

Generally, all manufacturers guarantee the batteries for at least 8 years, or 100 km. Some go well beyond. The guarantee is for the loss of at least 000% of autonomy ...

The number of cycles is detrimental, but a 50% to 100% charge cycle works for less than a half cycle.
Exaggerating, a battery supporting 5000 full cycles, could hold 15 in half cycle ....

A 5-year battery with 20 km will not necessarily be in better condition than a 000-year battery with 3 km.

What must be verified is when we reach less than 10-20% autonomy, that the cells are aligned, not one that is much lower than the others.

There is software for that, usually specific to cars.

MY ion, I think without too much worry, will still be there in 5 years, at the battery level. After that, there are known weaknesses in the internal charger of the ion, but if you are a bit of a handyman, a few condos, a few euros ...

If it's 3-4 years from now, and you're looking for an OCCAZ, there will be some really interesting models, with the correct autonomy.

My kona, there is a good chance that I will take it back at the end of the rental, it's not the best, but it's not bad.

So much for the biggest ....

Route to be optimized then, but just to give an idea of ​​a journey of the order of 1000 km in VE, about 12 hours of road ...
THE price of charges on highways can be high, but we can partly do otherwise, not always, to be cheaper.

I put in maximum speed 115 km / h.

Journey, which I suppose, in any case, that I do not do every day!
