German trials of electrified HGVs


When I were but a lad my grandfather, who was in charge of generating electricity and building power stations for the state and became head of the national EV association when he retired, said that trolley-bus systems like that were the best option for long distance EVs. 

His concept was that the "pantograph" would automatically retracted once you left the main road and you then ran on batteries; I assume that's the same concept above.

[QUOTE=423zero]Everything seems like a agenda that doesn't benefit the majority of the population, sensible people who can read and Google expert opinions tend to agree, battery cars aren't going to work, yet the original date of 2040 for sales of new ICE cars to end was shortened to 2030,why? There appears to be no extensive projections for the future of personal transport or impact on leisure and tourism. We have bicycles and motorbikes, battery motorcycles seem to be very efficient, perhaps motorbike and sidecar combinations you can tow with a bike and sidecar, get wet to. [/QUOTE

Our EV works, and we live outside of town in an area with about one third the population density of the Scottish Highlands (lowest population density in the UK) and about half the size of Scotland. We still have an ICE, mainly for use around the paddocks and the four hour drive down to the yacht on the coast, but will move to a plug-in hybrid later.

The EV is a little old one that doesn't tow but perhaps one of the changes people may have to make is to drive an EV to the dinghy park at their local club (as we do) rather than towing all over the shop.

Let me guess, you live in one of those 'problem' countries with twice the co2 emissions per capita of England?

The HGV is running on a working system in Germany, I think there are other systems in Denmark and a couple of other countries, not a new idea, you mentioned trolley buses. system uses 670volts DC, Must have a automatic system for dropping collector when approaching bridges, collector probably retracts when power cuts.

Long ago I tried to push the idea of universal sized batterys that you just switched at a gas station where they were stored in racks trickle charged by solar/wind, the fuel companies get to stay in the loop, battery production gets to be developed by rival companies all claiming better mileage etc, but all cars get built with a universal 'slot' to slide the battery in and out of, and charged for each use. Government would even benefit by vat on charging whatever. But just like dinghyworld, nobody with any vision or thought of standardisation in charge. So here we are with dozens of different cables, attachment points, charge units not working, no chance of dealing effectively with terrace street parking, everyone shy of all electric vehicles due to range fear. Typical mess brought about by capitalist competition driven dogma.

Agree with the batteries thing, but never saw you as a socialist?!

Good idea but battery capacity would be limited by the weight we could expect an 80 year old lady to carry, currently she just has to lift a petrol hose or a plug in charging cable.

Just a sensible design exercise, slide in and out on wheels/bearings, have to be rear mounted only problem I see is designing a tow bar solution.

Radical branch secretary of the local NUJ me in the 60's uncovering local council wage fixing scandals and apoplectic with rage when my Newspaper owner refused to publish (because of his own participation no doubt). Socialist living the capitalist dream now, complete with champagne if I can get my hands on it.

Still think it's all bonkers at this moment in time.

If I go and buy an EV tomorrow the energy source will still be 100% fossil fuels, all I'm doing is changing the process in which the energy is delivered to the point of use. Net effect is more energy consumed and more CO2 created.

The only attraction is a reduction in fuel cost which is purely due to a taxation anomaly that cannot continue if there is a mass take up, and which is massively outweighed in any case by the costs of changing, from my current vehicle.

When there is a surplus of renewably generated electricity it might make some sense environmentally to consider switching, but it makes absolutely zero sense at the moment
