We may soon see the end of cars that won't start because the batteries are too cold. Ultra capacitors that are much less resistant to extreme temperatures are being developed that will take the place of batteries in providing juice to starters.

Maxwell Technologies has partnered with Kromberg & Schubert to develop an electrical system that places Maxwell's Boostcap ultracapacitor near the starter to reduce cabling and overall system cost.


Ultracapacitors are a better choice for starting vehicles because of their superior reliability and small footprint, as explained in Maxwell's press release:

So adding a capacitor extends the battery life and allows smaller batteries to be installed. The technology isn't cheap today, but because they provide benefits to all kinds of vehicles --hybrids, EVs, and ICEs -- the research dollars being spent today will cut the cost substantially. It may take a few years, but someday you'll see ultracapacitors in new vehicles.

"Automotive batteries store a great deal of energy, but must be over-sized to deliver current rapidly enough for acceptable starting performance, and their ability to deliver such current drops off sharply when the temperature approaches freezing. Ultracapacitors store less energy than batteries, but can deliver ample current for starting at temperatures as low as -40 degrees..."
