      I left for the trip at 100% battery and got home with about 20% but there was a lot of charging along the way. The easiest way to think of it is that 189 kWh of total energy were used to cover a distance of 1037km. 1 gallon of gasoline is the equivalent of 33 kWh and 1 litre is 8.9 kWh.

      189 kWh / 8.9 kWh = 21.2 L / 0.89 = 23.8 L
      or
      189 kWh / 33 kWh = 5.7 gallons / 0.89 = 6.4 gallons
      When you charge it's only 89% efficiency so then you have to factor that in as well for a true total energy.

      So for this trip my MPG was..

      644 Miles with 6.4 gallons which is 100.6 MPG
      or
      1037km with 23.8L or 2.3L/100km

      Or you could just take 189 kWh / 0.89 = 212.4 kWh total including charging inefficiencies.

        That's right, 1.5KW charging is mostly useless but you could use it for daily driving in the city. In the winter it actually is useless. All the orange dots are DC fast chargers so I can't really think of a scenario where you'd have to charge that slowly.

          Glad to see some of the usual naysayers are quite interested in EVs.

          Paired with an on farm or residential solar system that is large enough to cover all or some of your annual usage you can in effect lock in lower electricity prices over a long term and can provide a significant amount of EV transportation that is more efficient and cheaper than fossil fuels.

          If you have a 500 km range and you only drive 10 -20 km to work every day then you have some extra capacity to use the battery storage for other purposes if it is connected to the grid.

          A powerwall could be used along with the EV batteries to store a lot of renewables. Automakers are planning for a 2 way flow of electricity whether its is just used for emergency outages or a supplemental source.

          Look up Vehicle to Grid.

          "Modern electric vehicles can generally store in their batteries more than an average home's daily energy demand. Even without a PHEV's gas generation capabilities such a vehicle could be used for emergency power for several days (for example, lighting, home appliances, etc.). This would be an example of Vehicle-to-home transmission (V2H). As such they may be seen as a complementary technology for intermittent renewable power resources such as wind or solar electric. Hydrogen fuel cell vehicles (FCV) with tanks containing up to 5.6 kg of hydrogen can deliver more than 90 kWh of electricity.[15]'

            V2G will never really be a thing and here's why. A car is engineered to travel down a highway a 60+mph and be safe in an accident. The thermal system is designed to deal with temps between -40 and +40 under varying loads. EV should be autonomous and delivering rides for more hours of the day. What I'm saying is that your EV would be better utilized as a taxi moving people around instead of sitting at home being used as a stationary battery. The whole point of a stationary battery is that it is always connected. Harvest energy during surplus and expel energy during high demand times. When the utility has a network of internet connected stationary batteries it will be able to reinforce the stability of the grid much better. Trying to manage the grid with cars in a million different places that may or may not be plugged in and at different states of charge seems like a logistical nightmare.

              Chalk up another point for common sense, Chuck's fairy tales, still 0. But keep trying.

                Thank you AF4 for having a rational discussion on EV’s , Chuck you don’t get it being an egomaniac condescending person with complete one way blinders on , you will never get it . Calling everyone else here Neanderthal, knuckle dragging flat earth and whatever other labels you have on here and are surprised by the responses you get says it all
                Again thank you AF4 for a common sense discussion here even though it’s not commodity marketing. It’s a level headed discussion on something that is going to be relevant to all of us farmers in the near future .

                Majority of people are open to the idea of EV’s and even climate change to a point , but not the way it’s being forced down everyone’s throat as a do it or else situation, that’s the definition of totalitarian forced society and it’s wrong .

                  The same generator would use roughly 1 litre of gasoline an hour So about 66 litres of gas to charge the car.

                  I like the idea of electric cars but I’m not ready.

                      A4 I really appreciate your perspective on EVs and renewable sources of electricity. We are on the same page there.

                      But I am not sure you are correct on the issue of whether EV batteries will be part of the smart grid storage in the future. Read the following Forbes article and let us know your thoughts.

                      Regardless EV batteries can store a tremendous amount of renewable energy that will probably be first and foremost used for transportation. As to whether they play a large role in supporting the electrical grid it is too soon to say. This a rapidly changing sector and who knows what the many players are planning to develop and use.

                      Electric Vehicle Batteries Will ‘Dwarf’ The Grid’s Energy-Storage Needs
                      Jeff McMahon
                      Jeff McMahonSenior Contributor

                      https://www.forbes.com/sites/jeffmcmahon/2020/01/29/electric-vehicle-batteries-could-dwarf-the-grids-energy-storage-needs/?sh=eec854f59299

                      There will be more than enough batteries in electric vehicles by 2050 to support a grid that runs on solar and wind—if the two are connected by smart chargers, according to experts at the International Renewable Energy Agency.

                      Electric vehicles are expected to carry 40 terawatt-hours of battery storage by that date, said Francisco Boshell, IRENA’s team lead for renewable energy technology standards and markets, compared to nine terawatts of stationary storage.

                      “If we see this from not from a transport perspective but from a power-sector perspective it also means that a massive electricity storage capacity would be available with all these batteries on wheels,” Boshell said in webinar posted by IRENA this week. “Batteries in EVs dwarf a stationary battery capacity in 2050.... This is indeed a great opportunity for the power sector transformation.”

                      If those EV batteries are connected to the grid by smart chargers, they could not only provide sufficient power but also many of the system services needed by a grid that relies on intermittent renewables.

                      Those services include primary and secondary power reserves, fast-frequency reserves, arbitrage, voltage control, and congestion management through load shifting and peak shaving, said Arina Anisie, who collaborated with Boshell and other analysts on an IRENA report on the topic.

                      “Vehicle-to-grid makes a lot of sense in the sense that the cars are parked 90 percent of the time, and the battery is connected to the grid for such a long time that we can actually use the battery to offer some services back to the grid and help the grid increase flexibility and integrate a higher share of wind and solar,” said Anisie, an officer in IRENA’s renewable energy innovation team.

                      “So it would be a win-win situation for both the transport sector and the power sector.”

                      There are seeming incompatibilities between the two systems, Anisie said, but they are resolvable.

                      For example, drivers will prefer fast or ultra-fast chargers to minimize charging time, but a smart charging system works best with slow chargers.

                      “It really needs to change the behavior of the consumer to be able to harness the synergies between mobility and wind and solar,” she said, though there are technical ways to resolve the issue too, including battery swapping or buffer storage at charging stations.

                      “There are several options to actually to still install fast charging that is much needed, especially on the highways, but to mitigate the stress that it puts on the local grid.”

                      There are other driver-based obstacles, such as concerns about range anxiety and battery health in a vehicle that exchanges power with the grid.

                      But not integrating the two sectors could be more costly and problematic than integrating them.

                      A study of Hamburg’s grid by the engineering firm Stromnetz found that if 97 percent of the city’s vehicles were electric, the grid would experience congestion at 15 percent of its feeders.

                      Upgrading the grid to fix that problem would cost €20 million. But a grid operator with access to a smart charging system could resolve the congestion for only €2 million.

                      “It reduces congestion at a much lower cost than investing in the grid solution,” Anisie said.

                      Vehicle autonomy may present another challenge, Anisie said. The prospect of shared autonomous vehicles means far fewer vehicles would be needed overall, and each would be connected to the grid for less time, which could deprive the grid of this vast mobile battery.

                      Ainsie recommended public officials study these potential changes in the nature of mobility but meanwhile incentivize smart charging and promote electric vehicles and renewables together.

                      “Both should go hand in hand.”

                        1 litre of gasoline = 8.9 kWh
                        66 litres of gasoline = 587.4 kWh
                        66 litres x $1.46 = $96.36

                        See what happens when you use a 27% efficient ICE to charge a battery?

                          A4 seemingly supports using EVs powered by solar and wind where possible. Hmmm? Who else suggested that many moons ago?

                            As far as name calling. Am I the only one? LOL

                            You cry babies deliver your fair share of name calling and more. You can dish it out but your sure can't take it.

                            The bigger problem is the nonsense and lack of evidence that goes with it from many of the usual suspects.

                              I just don't understand the concept of taking a useful vehicle and turning it into a stationary paperweight in your garage to power your house. A car has tires, wheels, brakes, air bags, sound system, air conditioning, aerodynamic design, battery pack that is designed to optimize energy to density. It just doesn't make sense to use it to power a house or grid. The stationary battery can be more efficient, have better latency, and more battery cycles. It just seems to me like using your iPhone as a hammer, like it kinda works but why?

                              Also hydrogen is a complete scam from a physics standpoint. Hydrogen has no place in the transportation sector. Diesel makes more sense than hydrogen imo.
