Anyone have any idea of the batteries of hybrids vs full on EVs? Are they similar, the same?

- toast0 2y agoDepends on the car I'm sure. But hybrid batteries are much lower capacity, and there's a lot less pressure to optimize capacity. If your EV has a 200 mile range, and you can optimize the battery to get 10% more range, that's useful. If your PHEV has a 30 mile EV only range, 10% more doesn't do much unless that's what it takes to hit a regulatory target. For a non plug in hybrid, a 10% increase in capacity is even less noticable. I think you'll see more focus on density (space and charge) in EVs because of this; but as EVs commercialize denser batteries, may as well put those in hybrids if the cost or space savings are meaningful.
- timbit42 2y agoThe battery in a HEV can only hold enough energy to go a few kms which results in about a 40% saving in fuel used in an ICEV. The battery in a PHEV can go typically 50 kms before it reverts to HEV mode. This can result in an 80% to 90% reduction in fuel usage, depending on how far you typically drive each day.
- WorldMaker 2y agoThere's a massive weight trade-off. ICE engines are heavy, even when just used as an electrical generator. Carrying that weight means a lot less weight for batteries (and a lot less capacity). So generally at this point the battery chemistries are about the same, but there's a lot less battery in a hybrid.
