Thread: EV general discussion

Had a good laugh at my brother's expense. He was in a very new, work EV and decided on Maccas for lunch. He pulled into the drive through, to order, but couldn't work out how to lower the driver's window!

He was on the 'phone to me, at the time and I found it quite humourous.

New and changes are worth noting. I tried working out 150Kw per wheel then thought why, I only buy or invest not build them The battery changes are cylindrical overtaking packet style and significant 'Consolidations' in the mass production side occurring.

The weird bit of the headline of this linked bit is 'but not with hydrogen'! The energy source is not relevant to the story so may be a LOOK AT ME type?


China unveils a strange in-wheel engine: The end of EVs, but not with hydrogen (ecoticias.com)

This is an inline electric motor by GAC Group that is one of the largest manufacturers of automobiles from China to unveil what is likely to transform the EV market. This new technology created by GAC Research and Development Department differentiate the automaker’s electric vehicle powertrain design from traditional approaches.
The in-wheel motor also referred to as the wheel hub motor is an electric motor designed to be located right in the wheel of the car. This design also does away with usual components of the drivetrain including gear boxes, driveshafts and differential, hence making this powertrain system compact.
GAC’s new in-wheel motor showcases several cutting-edge features that set it apart from conventional electric motors:

• High-Speed Operation: At its optimum speed, the motor can revolve at an astounding 30,000 rpm, which bests most of the existing electric motors used in present-day electric cars.
• Compact Design: The motor itself is rather small and measures only 330 mm in diameter, which makes it fitting to as many wheels’ sizes as possible.
• Lightweight Construction: Coming in a lightweight of 16. 8 kg, the motor further lightens the vehicle; thus improving efficiency and performance.
• Power Output: However, due to its size, it is able to produce a maximum of 150 kW of power, or approximately 201 bhp.

An in-wheel motor with an optimum speed of 30,000rpm. That would make it good for Mach 3!

I suspect somewhere there has been a “lost in translation” moment in this story.

GAC have just started production of a lightweight 30,000rpm motor, but it is not an in-wheel motor.

I hope my home battery doesn't do that.

Just check the recall lists. I'm assuming its installed in a fire proof enclosure either way (surely its not just leaning up against the house!).

You would have to be statistically extraordinarily unlucky to have a lithium battery torch off. Though I have noticed even the small ones now are starting to torch off in caravans (which absolutely terrifying, nothing burns better or faster than a caravan without putting an incendiary device under the bed in or the front boot next to the door

luckily the two I've heard of .... the caravan was sitting un-used .... not even plugged in when they torched off.

Yeah, well... I managed to short a pair of 18650 cells once. It's astonishing just how much energy these things can release, and even more astounding is the speed in which they can do this. Lucky I didn't burn the bloody house down.

Did anyone notice that when he shows a clip of a cybertruck in the street there is a bloke being run over in the foreground?
We have to also know whether the batteries are LFP or Lion. That has a huge bearing on the resulting fire.
