i believe that's the case with current batteries too. Car batteries, such as Tesla's, require both heating and cooling elements to keep them in an acceptable temperature range. Unsure what the exact temperature range is, but my guess is it's not too far off of those ranges.
Interesting fact: Tesla achieves their ludicrous mode (2.3 seconds 0-100kph) by pre-heating their batteries so that more power can be drawn. During my test drive, it took an estimated 40 minutes to heat the batteries to do this...
- ianai 8y agoDo capacitors have the same problem? I know they’d take longer to charge than discharge, but I don’t know temperature requirements.
- Baeocystin 8y agoCapacitors are blindingly fast in both charging and discharging compared to chemical batteries, and are much less susceptible to thermal variance in performance to boot. Their downsides are greater mechanical fragility, greater self-discharge, and comparatively terrible energy density.
- snarfy 8y agoI believe it would depend on the type of capacitor. A metal foil capacitor would have no problem, but an electrolytic might. The rate for capacitors is so much larger than batteries I doubt it's actually a problem.
