content: QuoteI read such a quote several times in this thread, and this is BS.If we switch to EVs this would add between 10% (UK) and 15% (Germany) to the electricity demand.For 1 million cars it would add ~0,35% and for 45 million cars ~15% in Germany.In the same time the overall demand is also rising based on growth of population. There is always the need for more electricity, and EVs are just a part of it.https://www.carbonbrief.org/analysis-switch-to-electric-vehicles-would-add-just-10-per-cent-to-uk-power-demandOn the other hand we get a lot of benefits, like reduction of CO2 emissions and we reduce the pollution with platinum, palladium and rhodium emitted from every catalytic converter.(FunFact: Do you know the recycle rate for catalytic converters is just 30%? This part is build with rare metals, similar to the batteries in an EV.)One remaining problem, in countries with a worn out electric grid, is the peak load. But even in every half-time break during the soccer world championship we can handle the peak at the whole EU at the same time.The whole transformation to EVs provides new jobs and new technologies. Its a benefit for our health. We can improve a lot.If someone doesn't want do drive an EV he can just stick with his conventional car. Who cares?It's the same with oscilloscopes. You can buy and use one of the new Keysight DSOs and have fun, or you can still use your old analog Hameg HM204. Think about all the new technologies and changes in electronics during the last 20 years. We got a lot of new and exciting stuff to work and tinker with. There are also some grumpy old man who condemn this, but this new stuff motivated a lot of young people to work with electronics again. It is an overall revival for electronics engineering.The same will happen with EVs.Cheershammy

content: Quote from: coppice on April 13, 2018, 10:13:49 amThese are doomsday predictions based on the gridtodayand is not including future local battery buffered charge points/stations and other advance in technology .All these assumtions are always calculating withallelectric cars need to charge thewholebatterycapacityat thesametime. Thats like saying all cars need to fill up the gas at the station every evening at the same time.Yes, I agree. In some countries, in some streets, there is the possibility a transformer can blow because all the EVs in this street.But this ist just a local event.Quote from: 2N3055 on April 13, 2018, 11:27:31 amLike in conventional cars your don't need to fill up the gas-tank completely, you also don't need to charge the whole capacity of an EV every evening/night.Your number is to high, we charge our car with 3.6kW (4.5 kVA). Usually every third night. Usually for 3-4 hours.Some countries will use more EVs than other countries. Like norway at the moment: 52% of all new cars are now BEV/PHEV. And it seams to work. For other countries maybe not, like eastern european countries.Bottom line: yes, there are changes needed to our power grid, but these changes can be incorporated during the normal growing during the next years. It will be a slow transformation what kind of cars people want to use, and we are talking about 10 or 15 years for this process. After that the rate of EVs is maybe 30-40% for normal cars. And the power-grid has to be developed, just because of population increase.However, my grandparents just had electricity for light, radio, cocking and the fridge. Later for television. Their need for electricity was way lower than our need today. And during the time we had always people who claimed we are dommed, when we use more eclectricity for these monstrous computers and all these other devices with high energy consumption. Think about the big datacenters we build all over the world. I would say they need more power than electric cars!Today we are still here. If our whole industrie can not cope with the demand of tomorrow, what are they good for? It's their job to get it right. At the end you are all saying we cannot keep up with the technology change we face. And this is just silly, if you look in the past and resume the changes in technologie we had over the past decades - and the growth.Cheershammy

content: Quote from: 2N3055 on April 13, 2018, 01:00:57 pmRoundabout 40km per day.Quote from: 2N3055 on April 13, 2018, 01:00:57 pmThats right. If you live in a city, without your own possibility to charge over night, a todays EV is not that practical. If your usage breaks down to a better ratio you can use your car over the week and charge it once a week at a fastcharger. Maybe somewhere during shopping or sitting at the barber. I assume we reach this point in 5-10 years.Quote from: 2N3055 on April 13, 2018, 01:00:57 pmFollowing the news I have the impression a lot of companies want a piece of this cake and the race had already started. All energy companies put their fast-charger at our highways, Shell in UK is also building a fast-charger network, partnerchips of car manufacturer are building fast-charger networks here in europe. ABB and other companies already building the technology. Fastned from NL is expanding ... there is a lot going on ... at least in the western part of EU. I cannot talk about the US, Canada, Chile or Moldova.Mainstream? No! But the already build infrastructure is already usable. We do longer car trips with our EV (500-700km) and we can charge during the trip (a stop for ~20 min) several times without problems. The daily commute is easy, we don't lose time and money at the petrol station any more.Is an EV practical or usable for everyone? No, it will never. Based on personal preferences and other conditions it is not feasible for all people. But the other way around it is the same for conventional cars.But thinking about infrastructure: 20 years ago I had my first cellular phone and cell coverage was not allways possible. Today we got LTE and Internet and all this stuff we can use with our samrtphone. Think about the needed infrastructure for thisshitwounderful world of apps and social network services. The amount of computing power behind this. The needed energy for all these datacenters. The companies who just exist beause of the smartphone (instagram, facebook, ...). Today I charge my smartphone every night, 15 years ago I was laughing about this. My Nokia was able to run the whole week with one charge.Cheershammy

content: Quote from: nctnico on April 13, 2018, 05:38:43 pmAnd again the same assumption: Over night all cars are replaced by EVs and the grid needs to be doubled.We are split what the exact numbers are, but whats the point? The grid needs to be developed? Sure! We need more electricity? Sure! We pay the companies for this development? Sure! They will handle this. It's a normal day-to-day process to develop, maintain and upgrade the infrastructure around us.The amount of EVs will grow over the next decades and also the grid will be delevoped in the same time. The world will continue to turn. Everything will be fine, don't worry!Cheershammy

content: The question should be "When Will ElectricVehiclesBecome Mainstream?as its not necessarily cars that are the most practical in the real world.see this video of Indian traffic why motorcycles are better then cars.the problem with most electric motorcycles thay are either too underpowered with poor range or have the performance needed. But otherwise are unaffordable.its theaffordablehigh to mid performance allelectricmotorcycle that will change everything.with good range. IMO its the cheap all electric motorcycle with performance and range that will win the day.updat-example of a hypothetical e bike specification5000 watt motortop speed 120kmhcab Weight 100 Kg with battery packcan payload 500 Kg pillion passengers500 km or more range on a full charge.interchangeable Lithium battery packs in standard sizes.easy maintenance with interchangeable standardised electronics.on board Ac overnight 8 hr battery chargerstandard motorcycle tyre and wheel sizes.cheap easy maintenance steel frame.can power 12v motorcycle accessories.

content: Quote from: DougSpindler on June 06, 2018, 07:15:43 pmWhere is the report on huge number of self driving car accidents, FFS? There is none in that document.QuoteBecause burden of proof is on person who made the claim. Andwhere is the freaking datayou are talking about? You made an extraordinary claim about self driving cars being involved in a lot of accidents, being orders of magnitude worse than real people, therefore it's you who need to back that claim with evidence. Where FFS are all of those accidents? You provided zero evidence so far. I did not even need to provide a link about Tesla autopilot, which is the closest as it gets to see how technology works in real life with regular people using it. And I don't call the data being BS (there is no such data) as you are implying. I call BS your claim which is not backed by any data.

Weather, especially during winter is nothing like it was 20-25 years ago. In China population is much denser, therefore effects are more noticeable. If China created as much pollution per person as US, it would be much worse than it is.
