I wonder what the comparison is in J/kg? I could see lithium & capacitor hybrid systems being viable in EVs.
The cybertruck's battery housing is full of plenty of deadspace, and if these caps have 1/10th the energy density you could squeeze in an extra 10+kwh of storage.
Caps typically have a much longer lifespan, so I could see them acting as a great buffer for the rapid charge/discharge of regen braking.
- skykooler 2y agoI recall following a project about 15 years ago where someone converted a car to electric using a lithium battery for range and a bank of ultracapacitors to increase peak power and handle the energy from regen. Here's the page on the project: https://www.metricmind.com/ac_honda/main2.htm https://www.metricmind.com/ac_honda/main2.htm
- ortusdux 2y agoGreat link! It looks like the caps he used were ~ 3 J/cm³, so 1/65th the density of the ones in the article.
