Your Argument is that it’s more efficient to charge an EV with a diesel generator than using it to combust in the car directly.
Yes, that is the premise. To put it as simply as possible, a diesel generator powering an electric drivetrain can always run in it’s peak efficiency band. A Diesel Engine directly moving a vehicle is not. If you had a perfectly flat course, and vehicle a running at constant speeds for extended periods of time at a speed that matches the peak efficiency of the diesel engine, then it would be the better option.
The fact is, hybrid systems are more efficient in real world conditons. We have hybrid cars all over the place, which are more efficient than their gas only counterparts.
The efficiency of a very good and big Diesel generator is ~50%running in its optimal state. You lose about 15%-25% from charging the battery. You already lost a minimum of 65% of energy before the car even rolled, which results in 35% of energy left.
A modern diesel car’s efficiency is >40%.
Hybrids are mainly so good because they win brake energy and such back by charging the battery, also because you charge it at the power plant, not a diesel generator. They don’t charge the battery with their motor.
Trains are hybrids because there arent Power lines everywhere. They dont use the motor to charge the battery either.
It’s more efficient than a gas powered car though, as theyre at about 25% efficiency. Not if you charge the accumulator with Gas though. Physics, I tell ya. You cant win energy by converting it more often.
Edit: When you charge the battery from the power plant, it’s efficiency is about 65%.
Or do you mean when you plug your car into the charging station?
Dont tell me you charged your car for 10 years with a diesel generator because you thought it would be more efficient.
Edit: There’s different types of Hybrids by the way. Judging by your replies, I assume you have one that only gets it power from braking energy and heat and going downhill, and doesnt have a plug.
Almost all of them charge via regeneration, so they do charge from the motor. My particular hybrid would also charge from the motor while in neutral (why spin the engine and do nothing with that rotation?) Plug-ins just have the option to top up from another source, but they will still charge from braking.
BEVs create a significant amount of waste heat compared to ICEs. Diesel electric trains and hybrid cars are less efficient than their ICE only counterparts and logistics professionals have been wrong for decades.
What? Your Argument is that it’s more efficient to charge an EV with a diesel generator than using it to combust in the car directly.
And that’s just flat out wrong.
Im not biting on your fast goal post movement to trains, which makes Zero sense to support the initial Argument

Yes, that’s at least part of the point.
Where do you think they charge from? Answer carefully, I drove a hybrid for the last 10 years, so I know where that energy comes from.
I answered that just one sentence earlier.

Your car wouldn’t switch off or to electric when idling, since that’s even more effective?
So, are you still arguing that charging EVs with diesel generators is more efficient than driving a diesel car?
Only if you are still arguing that…
BEVs create a significant amount of waste heat compared to ICEs. Diesel electric trains and hybrid cars are less efficient than their ICE only counterparts and logistics professionals have been wrong for decades.
Where did I argue that? Are you now putting words into my mouth?
Just admit you were wrong dude, it isnt that hard.
