Net Work

This month’s column brings the latest electric vehicle trends and new EV brands about to launch
in Britain, with updates on the power generation front and, of course, the latest from the LEO
satellite broadband sector.
P
revious Net Work columns
brought news of Britain’s
electric vehicle sector as the
lurch towards car electrification
gathers pace. The UK’s Society of
Motor Manufacturers and Traders
(SMMT) reports that 52% of all new
car registrations in February were
battery-powered (BEV), hybrid (HEV),
mild hybrid (MHEV) or plug-in hybrid
(PHEV). Those BEVs represented 16.5%
of all UK February car registrations.
Even so, 48% of new cars registered
in February were still petrol (gas) or
diesel – a far higher proportion than
in, say, EV-friendly Norway – but there
was of course no reference to used
car sales, whether fossil-fuelled or
electrically propelled. Despite the
interest in new EV cars, the high cost
and practical challenges of running
them puts them well beyond the reach
of many motorists struggling in today’s
financial climate.
However, the signs are that interest
in buying used EVs has cooled dramatically in Britain: wary buyers, already
feeling the pinch from the rising cost
of living and energy costs, are deterred by the dearth of EV charging
points, worries about range anxiety
and nagging doubts about becoming
lumbered with yesterday’s outdated (or worn out) battery technology.
As used EVs are gradually ‘returning
to the market’, some secondhand EV
models are suffering ‘incredibly large
drops’ in value, says car dealer journal
Automotive Management. They report
that the lack of interest in buying used
EV cars is such that some dealerships
have stopped stocking them altogether, in order to avoid getting stuck with
large inventories of rapidly depreciating
electric cars that simply aren’t selling.
Highlighted is the Tesla Model 3,
which has dropped over 33% on average in the past four months, and Tesla
also skewed the market by slashing
new car prices by up to 20% earlier
this year, as supply finally started to
exceed demand. Semiconductor shortages and supply chain problems didn’t
help EV sales either, so consequently
there is still a keen interest in buying

sensibly priced petrol cars instead. It
seems there is plenty of life left in older
petrol cars before sales of new ones are
banned altogether. Maybe those used
EVs will be sold off at bargain basement prices in coming months.
Who’s in charge?
Britain continues to drag its heels over
the supply of EV charging points. New
British housing stock is supposed to include an EV charging point, but as one
web forum poster pointed out, ‘if the
local electricity substation that feeds
your street has a 400A fuse, and every
house has at least one 32A charger, then
you do the maths. They can’t even roll
out smart meters for every house and
that’s cost more than £12bn so far, and
is far from complete... I understood that
the electrical load of a new housing
estate averages eight amps per property, and now they want to add 32A
for one EV on top of changing your gas
central heating boiler to a heat pump,’
the poster mused.
In the January 2022 issue I mentioned
a possible charging solution for EV
owners in the shape of a semi-portable battery pack on wheels, called the
ZipCharge Go. This well-publicised
powerbank was being developed for
‘topping up’ EVs in the street or car
park – the idea was due to launch some
time this year, but I now understand
that the ZipCharge Go never made it
beyond the prototype stage. This illustrates the typical vagaries of this
fast-moving tech sector.
At least British EV owners are not
alone in suffering practical problems
of EV ownership. An American EV
owner recently posted on Reddit: ‘Was
at the Electrify America station in Indiana yesterday. In a blizzard. With 30
miles of range and about 75 miles to
drive. Station had eight chargers. Only
ONE was working and it was in use.
The EA call centre was useless. Took
hours to get a charge when it should
have taken 20 minutes. Until this gets
figured out, electric cars will be limited, period.’ Sounds all too familiar.

registrations were exactly 13 (thirteen) GWM Ora £32,000+ electric mini

more Chinese EV brands, almost too

Northern Europe, starting with BYD –
an acronym for ‘Build Your Dreams’.
BYD is barely 20 years old and may
be unfamiliar to most readers, but
BYD is a huge Chinese conglomerate
that manufactures semiconductors
and batteries as well as solar arrays,
energy storage systems, EV chargers
and electric buses. Cars made by subsidiary BYD Auto will arrive in British

A year ago, in the May 2022 issue, I
mentioned this V2G or V2H (Vehicle

barely at a developmental stage here
in Britain. In comparison, BYD has
offered DTG (Direct to Grid) charging
since 2015 when its conventional-looking ‘e6’ car was first launched in the
US – it was the only car on sale at that
time with V2G included as standard.
As things turned out, BYD arrived in
the UK well over a decade ago, floating its ‘e6’ potentially as a taxi, but
the Chinese firm has kept a low profile
ever since – until now. As well as in
the UK (eg, Arnold Laver dealerships),
dealers for BYD electric cars have been
signed up across Europe. Traditionalists who prefer to use tactile knobs and
switches might not adapt so well to the
touchscreen way of doing things in an
electric vehicle, but the BYD Atto 3 has
a stylish interior dash that’s ‘built with

a ‘trendy and avant-garde design’ they
say, so its target market is clear to see.
BYD is presently slugging it out with
Tesla over pricing, but the BYD Atto 3

The Hinkley Point C nuclear power
station in Britain is the first new one
to be built in 20 years. Sadly, like a
number of other key infrastructure projects in Britain, it has suffered delays
and construction cost overruns. In
February the site received the first
of two French-built 500-tonne nuclear reactor vessels, as construction
of this ‘too-big-to-fail’ power station
continues with completion expected
within five years. Interested readers
can find more background on the history and status of Hinkley Point C at:

Previously covered in Net Work,
December 2022, the International Thermonuclear Experimental Reactor (ITER)
is an ambitious multi-national effort
being built in France to explore the
boundaries of nuclear fusion. The
ITER tokomak will not however be
used to generate electricity for the grid.
In February, after a near four-month
voyage from St. Petersburg, a giant
Russian-made 160-tonne poloidal field
coil was successfully delivered to the
ITER site, having taken some six years
to fabricate. Russia’s Rosatom is contributing 400 tonnes of equipment to the
ITER project, which has now reached
78% along the road to ‘first plasma’.

OneWeb continues to build its constellation of satellites intended to provide
Internet access between the North Pole
and the 50th parallel. OneWeb uses a

small batches of its satellites into LEO.

distant memories: when I hosted the
Ingenuity Unlimited column of readers’
circuit ideas here at Everyday Practical Electronics in the 1990s, I received
a circuit suggestion for a 4000-series
CMOS-based electronic rotary switch
from an engineer who worked at the
emerging Indian Space Research Organisation (ISRO) Department of Space. It
was carefully typed with a dot-matrix
printer on tissue-thin paper, which I
found in my archives (fortunately,
I’m ruthlessly methodical) and our
correspondence had always stuck in
my mind.
Fast forward 25 years, and in October 2022 a jubilant ISRO launched its
new LVM3 (Launch Vehicle Mk. III)
rocket from the Satish Dhawan Space
Centre in Sriharikota and it successfully placed 36 OneWeb satellites into
their intended orbits. The triumph was
one of India’s biggest ever commercial
orders, and the launch can be seen at:
http://bit.ly/3yFSAsn
OneWeb’s constellation of 542
first-generation satellites is nearing
completion, and a second launch from
India was due to lift off in March.
Following the outbreak of the
Ukraine conflict, 36 OneWeb satellites
worth some $230m were impounded
at the Russian-controlled Baikonur
Cosmodrome in Kazakhstan, where
presumably they have lain ever since.
It’s thought that they could now be
traded for some badly needed Russian
Soyuz stages languishing at the European Spaceport in French Guyana,
which is situated in north-eastern South
America. Roscosmos pulled the plug
on co-operating with the European
Space Agency, leaving critical Soyuz
rocket parts behind.
The European site accommodates
the European Ariane 5 as well as Russian-built Soyuz vehicles, but the ESA
continues to develop its long-overdue
Ariane 6 launcher which is now slated
to launch from French Guyana by the
year end. Last year, Arianespace signed
a contract with Amazon for 18 flights
carrying satellites into LEO for Project
Kuiper, Amazon’s own satellite-based
Internet service that is still seeking
regulatory approval. More details are
at: www.arianespace.com – note that
there is no website for Kuiper, although
projectkuiper.com leads to an enigmatic login page.
