Why have the hassle of plugging in a heavy, probably high voltage, high

In the pouring rain

Doesn't seem to be a problem for electric cars.

My phone and toothbrush have it, so why not the bus?

But a slight difference in the amount of power being transferred I think.
Not just literally between a toothbrush and a bus, but the degree to
which one can scale the engineering.

Yup, what of it?

The difference in size of vehicle.

The problem is for the driver (getting wet).

More relevant was the Rolls Royce Phantom which I quoted. Its batteries are
probably as big as a bus's.

How much does the installation cost and how quickly does it recharge the
batteries?

It was an experiment, so probably "a lot" and "too slowly". RR decided
there wasn't enough demand from its customers to proceed at this stage,
though apparently the car was terrific (very good performance and even more
silent than the V12 version).

I guess it'll come back when there are more city centre zero emission
zones, but the car had the usual EV range problem: it's fine in town, but
not for a longer distance run to the house in the country. Not many
customers, even for RR Phantoms, keep one car for the city centre only, and
another similar model for out of town usage.

Electric urban buses are different, as they only need a short, completely
predictable range. The same bus won't be expected to provide intercity
services. Inductive charging makes it possible to have frequent quick
top-ups on the road, not just in a depot or terminus.

Anyone know how that trial with the single deck electric battery buses around
Victoria is going?

There are two Chinese BYD buses on the 507 and 521 but one has oos for
a while now. Not sure why.

Two more buses - this time Irizar all electrics - have been ordered.
One has arrived and entered service with the second not yet seen.

Why hasn't Wrightbus come up with an offering? Seems to me they've been
caught napping over this.

Even though the trial has not concluded the new contracts for the 507
and 521 were announced yesterday. London General has, unsurprisingly,
retained both routes. The big surprise is that the fleet of Mercedes
buses will be replaced with new all electric single deckers. The make
of the buses has not been announced yet. It will be interesting to
see what is bought.

It would be interesting to see if they could cope with steep hills on routes
without a serious reduction in range. Highgate and hampstead spring to mind.
One would hope they use regenerative braking though so perhaps it wouldn't
be too bad.

Still, they'll be a welcome addition. Far better than the hybrid buses which
seem to be hybrid virtually in name only with their diesel engines operating
90% of the time in my experience.

Several manufacturers offer that option so it would make sense to test
it even though there will be issues as to where you can install such
kit.

Is that a single wire tram-style pan, or two wires, trolley-bus style? If
one wire, how is the bus earthed while being charged?

Google siemens electric truck. It'll probably be a similar setup to that.

I doubt it. On the youtube video of one of the BYD buses it says the
batteries weigh 3 tons.
