A guy who used to work beside me had a CRX with the registration number H15 CRX.

Honda made some crazy stuff in the early 2000s. My neighbour has a CR-Z - probably the kind of thing I would have bought in 2010 had I not been a poor graduate.

There’s a CR-Z on the business park where I work, it’s definitely different looking… no idea what they’re like to own and drive.
The battery pack is trouble-free, and the hybrid drive is over-engineered, so a used CRZ may be a decent S?H purchase

New Lead - carbon batteries look promising, still heavier than Li-Ion but with many advantages and a big advance on conventional lead-acid. Obviously lead batteries are easy to recycle.

Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

I wonder how the real cost of the charging compares with petrol? A 100kWh battery would cost £15 to £20 to fully charge at current domestic tariffs. Free / subsidised charging will disappear as the number of electric vehicles increases.

Hybrid has a lot of potential as (i) there's the recovery of energy lost to braking and (ii) it allows the engine to spend more of its time operating under the most efficient conditions. Honda's Mk 2 Jazz hybrid was a bit half baked as both the battery (a heavy lead acid lump) and motor/generator were of limited capacity. A hybrid version of the Mk 3 Jazz is sold in some parts of the world but not here.

Are you sure about the lead acid traction battery?  Honda used exclusively  Nickel Metal hydride batteries, then Lithium ion starting with the CRZ, though early CRz cars had  Nickel metal hydride

I've seen a Japanese import of one of the Mk3 hybrid Jazzes (actually a Fit) on AutoTrader. The mpg and power figures looked good. I wonder how problematical servicing, repairs and parts in the UK would be as I'm quite tempted.

"UK 'lacks clear plan' to phase out petrol and diesel cars as charge points remain a postcode lottery
Some local authorities, particularly in London, are well-served with charge points but others are falling behind."

Your average person with no off street parking and used to buying used cars under a few grand isn’t going to be rushing to go electric anytime soon. It’s a bit pie in the sky this 2030 target, let’s hit the motorist and never mind aviation or shipping, their fossil fuel consumption is acceptable. The amount of on street charging points needed is going to be bonkers, never going to happen, will take a hundred years to get the infrastructure in place. People can’t afford to make the switch, and add to that the gas boiler ban they talk about, that’s more cost to homeowners, not everyone has a spare 20 grand down the back of their financed scs sofa.

I think the cunning plan is that currently-unproven technology will magically solve the problem, therefore BoJo won't have to actually do anything apart from claim the credit. For example:

I have worked out that I contribute one hundredth million of one percent to CO2 emissions and I am being asked to make that fifty millionth of one percent.

To do that I have, at least, to eat flies to "save the planet".

Is that a world really worth anyone living in?

My Mk4 Jazz has a electric motor rated at 80Kw.
Honda quote the battery voltage as 173 volts, so the current required for that power output amounts to 462 amps. (unless I've got it wrong)
Now I know the average battery capacity of an E-car is in the order of 35-40Kw.
If they are going to be fully charged in 5 min, then what sort of current is required?

All electric cars charging in 5 minutes on a Friday night will cause patrts of  the Grid to shutdown for its own safety.Especially before Bank Holidays.

And then take two days to reset as many chargers will be left connected.

Oh that's why we have Smart Meters..just disconnect the areas with fast chargers.
(London goes dark)  :P

Could you show your working please?

I would think it would be relatively easy for people in the western world to cut their carbon footprint in half without undue hardship. Not so for those in third world countries.

That calculation looks right to me.
For charging at 173 volts in 5 minutes I get it to 4,600 amps. 500 volts gives 1,600 amps. Scary  ???

The technology to solve all the problems is always 'just around the corner' - trouble is when you get to that corner there is nothing there, so you wait for the next corner---- ad infinitum. Politicians are good at making vast expansive claims ( or should that be vastly expensive ? ) without blinking, often their thought process is no deeper than the average carpark puddle.
