> For most city vehicles, a PHEV will electrify the majority of the miles with a fraction of the battery capacity. There have been studies on how PHEVs are used in the real world and this is just not what's happening, see e.g.: https://theicct.org/publications/phev-real-world-usage-sept2020 https://theicct.org/publications/phev-real-world-usage-sept2...

On the other hand, the study proves that PHEVs with decent battery capacity actually do that, the average is just too low: >. Most PHEVs have type-approval all-electric ranges of 30–60 km and electrify 5,000–10,000 km a year. PHEVs with high all-electric ranges of 80 km or more achieve 12,000–20,000 km mean annual electric mileages, which is comparable to the annual mileage of the car fleet in Germany and the United States.

> For private cars, the average utility factor (UF)—the portion of kilometers driven on electric motor versus kilometers driven on combustion engine—is 69% for NEDC type approval but only around 37% for real-world driving Not a majority, but 37% of your driving on electric is a significant chunk. Would And to take a Prius Prime for an example, you can still have a very efficient vehicle when you're running in normal hybrid mode: > C/D observed 75-mph highway driving (hybrid mode): 47 mpg / 49 mpg / 47 mpg If you're trying to make the most difference with limited battery production, that's 8.8 kWh of batteries for a Prius Prime. You can make more than 6 of them with the batteries that go into a single "low range" Model 3 (54 kWh). Six cars doing a bit over 1/3 of their miles in electric mode, or one car doing all of its miles in electric mode? That's a relatively short electric range car, if 25 miles isn't doing enough for most people there's probably a good middle ground where you use half the batteries of a long range EV but cover 90% of your milage in EV mode. This is of course ignoring that the Model 3 is a lot more fun to drive than a Prius Prime, but just to make the point about battery usage.

  It was kinda my dream to have drop-in kits that would turn any ICE into a plug-in micro-hybrid and just run the electric system off extra batteries for as long as possible, and then kicking in the alternator once finally required. Could work as more and more stuff becomes electric in cars instead of running off accessory belt.

  You can also fully charge a 10kWh battery overnight on a 120V charger.
