Electric Bus Stranded
Discussion
Flat battery after "five charging points in Cornwall which could not be used to charge the vehicle there were another five on the journey from London to Cornwall which could not be used"

The (sort of) irony being that electric buses are much loved by bus operators precisely because they actually are much more reliable than ICE buses.
You probably don't realise it, but the UK is covered by a network of heavy recovery services that spend a huge amount of time and effort recovering buses when they have broken!
Because 'lecy buses are much simpler, and critically, don't have multispeed gearboxes, clutches (or torque converters), exhaust systems, and complex high performance cooling systems, they are more reliable in the field.
But yes, you do have to charge them for them to work........

I remember Essex had some Volvo hybrid double-deckers. The trouble was, Basildon, like most new towns, had many roundabouts. So these buses would pull out onto a roundabout running on electric power, then halfway across the roundabout they would be a hesitation as the diesel motor kicked in. Quite unnerving, both as a passenger on the bus, and as a car driver entering the roundabout and having an almost stationary bus in front of you.

It’s is interesting that three of the points recognised the coach but the coach did not charge….maybe more fault with the coach software than the points?
Bit of both. CCS standard is poorly defined, too many automotive companies have poorly interrupted it and left it upto the charging company to resolve with a workaround.It's classic day 1 issue with new EVs on the market.
Really, this is an inappropriate use for an electric bus. Electric buses make most sense in cities with many stops and stop-start traffic, where they can easily get to the depot at the end of the shift and be charged overnight. Certainly not a long distance coach.
The ideal fuel type for a long distance coach would be a diesel-electric hybrid with the wheels solely driven with electric drive and the diesel engine acting as an electricity generator for the electric motors, just like with diesel-electric trains. That way you are mitigating reliability issues thrown up with drivetrains and gearboxes, etc.

Says: It can be charged with either a 60Kwh, 90Kwh or 120Kwh DC charger making a full charge possible in less than two hours.
Trying to charge at 50Kwh and 170Kwh chargers didn't work you say? Mmmmmmm. Does this bus even talk properly to "normal" UK chargers?
Does feel like a bit of a publicity stunt. Oh noes, we got stranded at the extremely picturesque Eden Project and now would like to talk about the need for investment in UK charging infrastructure as shown by us being unable to charge our bus at public charging points. Just all very odd.

You have thought the roof of a coach would be able to havee a good ammount of solar pannels the flexible type bonded to then would easily provide 1kwh+ on a Sunnny day
Now obviously wouldn't provide a huge range given the weight but certainly a ammount worth having
1kWh will probably run that bus for 1 mile if that, so even on perfect sunshine 1KW of PV panels is essentially useless for anything but keeping the HVAC system going.Now obviously wouldn't provide a huge range given the weight but certainly a ammount worth having
Just seen that bus has a 280kWh pack, so assuming 12hrs a day of perfect sun shine and 1KW of PV panels it would take 23 days to charge that pack assuming 100% charging efficiency.
