Clarios Supercapacitors
We harness advanced Supercapacitor technology—often called “supercaps” or “ultracaps”—to deliver the instantaneous power modern vehicles demand. Designed for systems operating within a 12-48V range, our supercapacitors often work together with our lithium-ion batteries or lead-acid batteries to release rapid bursts of energy for high-load events such as steer-by-wire, active suspension, and other critical safety functions. The result is on-demand power in any driving scenario, reduced strain on the primary battery, and state-of-the-art functional safety across today’s software-defined vehicles.
The Power of Supercapacitors in Modern Vehicles

Power Boost
Delivers a rapid surge of power, even in challenging temperatures, to instantly support critical vehicle operations when the battery needs a boost.

Powernet Stabilization
Reduces low-voltage system complexity by smoothing voltage fluctuations and providing efficient energy buffering.

Longer Cycle Life
Offers an extended cycle life compared to traditional lithium or lead systems, ensuring reliable power delivery even in low-temperature environments.

Safer Design with Higher Power Density
Supercapacitors offer enhanced safety and high power output compared to lithium-ion or lead-acid systems, as they store energy through physical mechanisms rather than chemical reactions.
Engineering Excellence
We channel our deep engineering expertise into advancing supercapacitor technology and broadening our energy-storage portfolio. As the demand for efficient, high-power solutions grows, our Supercapacitors unlock unique benefits for tomorrow’s vehicles.
By collaborating closely with leading OEMs, we integrate premium Supercapacitor cells into next-generation architectures while sourcing those cells from trusted partners. This strategic approach lets us focus on system-level innovation across our current lineup, solidifying ourselves as the preferred partner for advanced low-voltage energy solutions.
Powering Advanced Vehicle Features
Our Supercapacitors are engineered for virtually any platform—from everyday passenger cars to heavy-duty commercial vehicles—delivering the rapid power, functional safety, and sustainability today’s software-defined vehicles require.
