Ev vehicles sask

So on your example trip post your consuming about $2 an hour or do you have some at home at the start and the finish?

This a great discussion with someone who is actually driving an ev. The diesel electric drive for tractors intrigues me the most.

And why not take that a step further, and put the electric motors on the wheels of the implements, and get rid of the over ballasted tractor in the front, dragging around a bunch of dead weight wheels, compacting every step of the way. Just move the power plant from implement to implement.

What we have now is akin to if we had kept the horse and buggy arrangement in modern automobiles, and the passengers still sat in a trailer behid the power unit.

So like bringing a little honda 1500 Wat inverteewith ya how long would it take to charge with that just in case?

thanks AF4
nice to have real life experience teachings instead of the pre packaged drivel we receive on here
thanks again
very interesting

A 100 KW battery would take a little over 66 hours to charge with a 1.5 KW generator.

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.
