It's quite easy to pinpoint certain stories and highlight specific journeys in all their positive light . .. . . . . . . my concern is, without sounding negative, what the impact will be on national grids if and when 100's of thousands and then possibly millions of vehicles are making these journeys and using the charging stations?

That concern is not just centred around just supply, but costs too.
Energy and utility companies are already fleecing domestic and business customers.

In the UK the Grid operator has already calculated that 10 new Hinkey Point stations will be required just to cope with the increase in electric vehicles. Sadly none are approved, yet old coal and even gas plants are scheduled for closure. The UK now imports a substantial amount of electricity from Europe, where in the event of a dispute the UK would be in dire straights.

What I want to know is that seeing as how this changeover from fossil fuels has been coming for years, why hasn't the Grid been increased already?

In the UK it is simple, they have a lack of government budget, an over cumbersome almost impossible to comply with Environmental approval system, Just look at Heathrow 3rd runway which has been on the table for years but can never get approved.
The UK has only recently stated it's 2040 objective to mover from some fossil fueled vehicles and they have still not passed a law on it. They have not made their objective clear on ships, planes, motorbikes, trucks or even generators.
In some countries, UAE/Saudi/Qatar/China etc. if the boss says do it, then it gets done. In the west it is debate for the next 20 years and still nothing happens.

And we all know that nothing will happen in Ting Tong Land in our lifetimes.

D-EV Project: An Electric Ducati?

"This machine right here, the “D-EV Project” is initiated by the owner of Ducati Thailand “Natapichat“. He’s an early adopter when it comes to EV vehicles and he is a fanatic EV-user since 2011. In this project he took a Ducati Scrambler as a base bike and put in a 33Kw engine in it with a 5.6kWh battery. This machine puts out an impressive 107Nm (right away!) and makes a top speed of 160km/h possible. The machine weighs just 165kg and has a range of over 100km. Pretty cool… for an electric motorcycle…!"

I just read a series of articles that I googled. In 1900 the horse was King for personal and commercial transportation. By 1920 the motor-car had replaced the horse for most all personal transportation. The Ev revolution maybe a little faster. On the other hand, experts say because of the relatively small output it will take 10y for the number of EV cars to reach 5%.of the total.

Nothing new:
…………………………………………………………………………………………………………………….
1975 Series 111 109” 1993 Electric Drive evaluation vehicle

http://www.dunsfoldcollection.co.uk/col ... -prototype

Chassis number: 91127537C
Registration number: Q539 CPF
Engine type: 2.25 Petrol/Battery electric
Gearbox type: 4 Speed
Vehicle spec:
Although on first impressions this looks to be a standard Series 111 109” military Land Rover, there is an important difference. The engine and running gear are in place but the back is packed with eleven aviation-type gel sealed batteries connected to produce 216V and there is an electric motor driving the PTO point on the gearbox.
The vehicle dates from 1975 but the conversion was carried out in 1993 at DERA Land Systems at Chertsey as a trials vehicle for use in Northern Ireland, the obvious attraction presumably being the potential for silent running.
Flicking a switch on the dash and engaging the PTO swaps power from petrol to electric. The brakes use an electric vacuum pump and drive is broken by a switch on the brake pedal pad. There is a rheostat on the throttle pedal which controls the current.
We understand that three of these were built and tested, the other two being Defender-based, but they never went into production. Silent drive except for the noise of the military tyres!

The following is from a bloke in Australia that has converted a Land Rover to a modern type of VVF drive using off the shelf components. His comments on the batteries are interesting:
……………………………………………………………………………………………………………………………………………….

https://www.aulro.com/afvb/alternate-en ... ia-12.html

It only takes one bad cell to pull down a whole pack , The cells don't degrade so much as they are not created equally. In service complete battery packs are discarded because of one cell . I have 45 x 200ah cells in mine and one is faulty from new, I estimate that cell has a real capacity of about 120 Ah so effectively brings the capacity of the entire pack down to 120ah I know this because my Battery Management System monitors the voltage of each cell , This one bad cell drops to 2.8V whilst the rest are on 3.1V From 2.8V there is a steep drop off to 2.6 from whence there is no recovery so I have my BMS shut the car down when the bad cell is at 2.8 .(BMS=battery monitoring system)

As well as that one bad low cell , I have two cells that go high (I have BMS set to stop the charger when a cell reaches 4.5v) before the rest of the pack , so they fully charge before the others , thus again limiting the pack capacity. If you charge too high you can kill a cell, Thus a BMS is vital.

I have 4 new cells on the way from China , Rather than waste the bad cell I'll pick out the 4 worst cells and use them to make a 12v lithium pack for my caravan. Should last for ever.

Used Nissan Leaf packs are a really good way to go , only the low & high cells will be abused the rest will last another lifetime.

Here's a video clip about the PEA charging station in Hua Hin. Supposedly to be installed all over the country as well.

How long does it take to fill up? I've always imagined hours (based on my experience with electric fork lifts about 30 years ago :oops: ). If it's more than a couple of minutes, I envisage huge queues.

:thumb: Have now had a look and you have quite a few electric car/electronic themed videos. I post a link to your videos here in case others want to take a look. Pete :cheers:

I wouldn't have classed it as rambling Image. Thanks for taking the time.

so those are the level 3 fast chargers--how long do they take to give a full charge

I think that's what I asked - nobody seems to know :?

Where does it say it is a level 3 charger? As far as I know a level 3 charger is a DC charger and requires a 480 volt AC supply. This is in comparaion to a level 1 and level 2 charger which is part of the car, and can therefore be plugged into a household 220 volt outlet. How "long" any of them take to "fully" charge a battery cannot be accurately stated, as several variables are involved, such as the type of battery, how much "charge" it still has it, and the output capacity of the "charger". Level 3 is is undefined as far as I am aware.
