Another example of how KWh is the wrong unit for energy storage — gets so many people confused and they don’t know the difference between storage and power.
Looks readable, human-scale, easier to type than kWh.
To compare, 1 gallon of car fuel is about 120 MJ of thermal energy content, so about 40 MJ of mechanical output energy content, if we acccount for the ICU efficiency and transmission losses.
As an EE I much prefer kWh, though its not all that hard to add the factor 3.6 if you really want MJ
I think you have curse of knowledge, frankly.
ChatGPT: The sentence has a minor issue with the term "kilowatts". Kilowatts measure power, not energy, so it should be "kilowatt-hours" (kWh) if you're referring to the energy capacity remaining in the battery. "
For all the negativity of AI i keep finding examples where it's very clear "you could do a much better job with less effort if you leaned on AI a little". Journalism especially.
And that seems to be quite relatable if my circumstances are known by the recipient.
Many of these characterstics will be shared among us (climate, roads, landscape, charging infrastructure etc).
Part of it is getting their thought processes away from "peak requirements" and into the direction of "average everyday" which for me is a more important measure.
I wouldn't recommend cars be advertised this way but person to person its quite useful.
Any reason why/why not?
They also wonder whether it's practical to own one without having access to home charging.
Explaining it this way conveys the "impact" to daily life better than talking strictly about numbers.
Me saying "usually I charge once a week while getting groceries" is lived experience and quite relatable (I hope).
I also try to be honest and not make any claims about use cases which are not mine (I'm not trying to sell something). I very seldomly do long drives > 2h so if someone does that regularly, my personal experience won't apply.
Of course if people want to nerd out over kwH and kW I'm ready to do that as well but many don't care about that.
Edit: Everybody knows how gas cars work. No need to explain that. But my friends and family are curious about EVs.
Can charge at home? super convenient & time savings.
Charge at work? may be subsidized by employer, but you may have to go move the car during the day, etc.
"while shopping for groceries" is an interesting "3rd space" - you're going there consistently, so if charging works on that time frame (charger space available, doesn't require you to delay after shopping or interrupt the shopping, etc.), it's a great fit.
KWh (kilowatt hours) is a measure of energy, so using it to describe energy storage capacity is correct. Using KW for this is wrong.
