Fast Charging Vs. Slow Charging:

[placeholder]

Well, according to a recent study from Recurring Auto that analyzed charging data from over 12,500 Tesla vehicles in the United States, the rate of range degradation is statistically similar when compared to AC charging.

The company, which provides vehicle and battery analysis reports for EVs, compared cars that fast charge at least 90 percent of the time to cars that fast charge less than 10 percent of the time, and the results show little to no difference between the two charging methods.

The charts below show the percentage of the original range as shown on the cars’ dashboards – in this case, the Tesla Model 3 and Tesla Model Y – and the number of days.

So true and the reason I will never buy a EV auto and have to worry about how fast my battery charges or where to find a battery charging station.

Do you worry about where to find a petrol (gas) station when your tank gets to 25% full ?

If not, why would you worry about a charging station when you have 25% range remaining (which would be about 100km on a normal E.V.)...

 

Additionally, if being used for 'normal use' (work and back / school run etc) then there is no need to find a charging station as the car is charged at home...  Thus making the question about looking for a petrol (gas) station when the tank is 25% full somewhat redundant, as the need for any filling station or charging station is primarily removed. 

 

 

I don't own an E.V. (my car is actually diesel), but I do like to see intelligent pro and con arguments and not poorly thought out emotional bumf on these threads which are often informative when facts are discussed and emotion ignored.

 Does it ???  

 

How many times do you fill up every week ???...   We fill up about once per week (which takes about 10 mins I guess from pulling in, filling, paying etc to driving off).

 

IF we had an E.V. filling up the car wouldn't take any time at all, as it would be filling up when parked at home...  The only time it would take is to plug it in and un-plug it.

 

So... Theoretically, when considering the factors involving every day and regular use, 'electric' fills a lot quicker than ICE cars unless of course the E.V. is regularly being used for journeys which exceed its range, in which case the E.V. is not the ideal car for that situation anyway.... not yet at least.

Good to know as I've scheduled an appointment to test drive an all electric car next week.

Tesla's fast charges have a very high favorability score and they've just opened them up to users of other EV's.

Many EV owners suffer from "Range-Anxiety" and worry that they will not make it to their next destination:

I probably would too... 

 

But isn't that more a 'fear of the unknown' after being in a world where ICE's and filling stations are the norm?

 

While suffering a dash of 'range anxiety' I'd still have to have a mental word with myself, point out a bit of common sense and remind myself that my car only needs to do about 60kms per day, yet has a range of 400kms.

 

In short the 'range anxiety' issue is perhaps one borne more out of emotion and a lack of understanding than any genuine issue with E.V's.

Range anxiety is something I suffered when I was a new EV owner since I never noticed EV Charging stations before, now I see the CS everywhere and it no longer worries me.  I wouldn't think twice about jumping in my EV and driving to Bangkok, I wouldn't even bother planning Charging stops, there are that many.  I would plan a hotel with free overnight AC charging though.

 

I have used a Fast DC Charger once in 2.5 years of owning EV's and that was to test it for 10 minutes or so.  I have used lots of free AC Charging stations in places like Central Mall, Coffee Shops, Restaurants and a hotel.  The hotel was the only one I needed as it was an overnight stay before leaving Kampheng Phet for home, the other AC chargers I used because I was there for food/coffee/shopping and they were free (so why wouldn't you!).

Does the result show "battery life time" of both charging methods ? I don't think so ????. Fast charging will reduce batteries life time. And I don't care what auto makers say regarding this.

Well, it wasn't automakers who said this. It was a company that gathers data for fleets and such. Really wouldn't be in their best interests to lie to their customers. But, of course, you may have actual evidence to counter their report. I await your findings with interest.

[OneMoreFarang]

I know about lithium batteries from the RC world.

Some of those batteries are designed for fast charging, some are not.

If a battery which is designed for fast charging is fast charged all the time that is no problem.

But it a battery which is not designed for fast charging is fast charged a couple of times, that reduces the lifespan considerably.

In fact it is in their best interest. Read news not limited to Asian now.

Found this. Company called Aviloo seems to think that fast charging is not good for your battery. But seems not many cars tested.

Why does it feel like the dinosaurs are reliving the early 1900s? No one took away the horse n buggy, no one is taking away your ICE. Options are good and many seem to like the EV option. End of.

The study doesn't give or state much info, except the results.

 

Many things affect battery life, charging just one of them.  That manufacturers advise slower is better, is a bit telling.  

 

Heat is not a batteries friend, and fast charging produces more heat.  Although, 'newer' tech, chemistry and built in safeguards, BMS, help minimize the negatives of fast charging.

 

Enough so, that slow vs fast, may have minimal long term effect.  Or so I read elsewhere.

 

What the study doesn't state, is year & chemistry of the batteries being charge, and many other factors with affect battery life.

 

Tesla use 4 different battery chemistry's, since year 2000.  Where were the tests and cars in the test located.  In hot or cool or colder weather.  

 

Though agree it may make minimal difference, the test if flawed for not providing more info.  One brand car, no year or chemistry of batteries.

 

Along with study possibly only using Tesla's super chargers.  Who funded and provided the info that was studied?

Yep, they'l have to raise the price of  gas to 12 Bucks a Gallon.

This is a company that advises fleets. That's where their income comes from. So really not in their interest to tout battery falsehoods.

If they have a motive. Given their customer base, what would that motive be?  Given your general history of posting, I'm going to guess that accusations of corruption are about to follow. You know, make stuff up to further your claims.

You might have to worry about where to get fuel for your old clunker in a few years time. EV sales in many countries already out strip Diesel sales. Fuel stations are being converted to EV charging stations.
