But that as not an engine for moving the vehicle means no emission standards required so the choosen engine had no emission controls meaning more pollution than having a standard bus.


so what you are saying is I can have an electric pick up and sling a diesel generator in the back connected to the charge point and drive around london?


Exactly.
This is what a friend of mine plans to do. If diesel ban will be a PITA he will convert his syncro to all electric and will tow a generator.

it will be short lived, the loophole will be closed as soon as any number of people do it.
Also most standard vehicles probably can't be charged while driving... Computer says no.

I was talking to a person at work who has a BWM electric car, I asked about the range etc as thought it might be ok for the wife. He mentioned that he had ticked the 'range extender' option when buying it, I thought that would be an extra boot full of batteries, nope.... a 650cc twin cylinder engine driving a generator so you might as well tow one.

:D

I wanted to see how long it would take before itchy realised his invention had already been made.

Range extenders do deal with range and rapid energy replenishment. You then have to look at what fuel the range extender uses. Ethanol is a decent option as it is replaceable and the carbon cycle is measured in years, not millions of years.

The range extender in the BWM doesn’t produce enough juice to charge the battery faster than you use it at normal speeds - it merely slows the drain giving you extra range. It might be enough if you were pootling along slowly.

Serial hybrids use an electric drivetrain and a generator which burns fuel but the power output is a fair bit higher than your average generator - 35-50kw range.

There are some awesome designs being worked on using mini turbines which can burn pretty much anything and are a good bit more efficient and less polluting because they can always run at peak efficiency levels - no change in demand - just on or off. It allows smaller batteries for daily commute and an option to run on hydrogen or ethanol or any fuel for longer journeys.

Ps. Your ‘granny charger’ safety mode typically prevents driving while charging. Some safety reason or another ;D

TFL has been running a trial of a small fleet of single deck hydrogen powered buses for about 15 years now, so the technology works for larger vehicles too. Next year, a small fleet of new hydrogen powered double deckers will arrive in the capital, so this technology is here to stay.

Wheeler Dealers episode with the updated electric Maserati BiMotor was on Quest last night.
Parts from EVWest in the USA.
Got me thinking.

E.V. West Coast in the US are selling kits for VW from beetle to bus to bolt in Tesla Model 3 motors and control systems after they reprogram it. One of their videos he raises an interesting point, they have a Tesla wall bank and solar panels, they’re completely off grid, including charging their vehicles. They’ve thoroughly gone zero emissions, but it won’t have been cheap.

Tesla really dont like their hardware being used in aftermarket applications though!

Correct, E.V. West change the firmware in the motors to accept aftermarket controllers as they also don’t like to work without all subsystems attached even down to door handles, Rich Rebuilds has a load of videos on this stuff too. There may come a day soon where we need their products if we want to keep our vehicles, but it’s prohibitively expensive without some kind o subsidy.

So I wasn't too far off the mark when I mickey tauntingly suggested that we might have to stick lolly sticks into the wheels of EV's in order to save slaughter on the roads :ok

Soon the local youth will be fitting V8 sound system and big under car speakers linked to the throttle.

When I was at Goodwood FOS last year, Milltek Exhausts were proudly claiming to be first to market with exhausts for EV's. Basically a stainless pipe with an electronic speaker unit hidden inside.
