Design it. Simulate it. Perfect it.
Bring your ideas to life, faster. Our SPICE models and design simulators let you simulate real-world performance, so you can explore, refine, and perfect your designs with confidence.
Transportation
Power when it matters.
From starting engines to supporting regenerative braking, supercapacitors deliver fast, reliable energy that enhances efficiency and performance in modern vehicles.
Engine Starting
Reliable cold starts in trucks, buses, and locomotives.
Stop-Start Battery Support
Reduces battery wear and improves efficiency in hybrid vehicles.
Regenerative Braking
Captures braking energy and redeploys it quickly.
Power Steering / Suspension Systems
Smooth, responsive energy delivery without strain on batteries.
Boost Battery Life
Supercapacitors help reduce voltage drop during peak loads, allowing coin cells like the CR2032 to use more of their stored energy. In testing, adding a CAP-XX HA202 supercapacitor extended battery life by up to 55%, ideal for devices with frequent short bursts of power demand.
Power Smarter Key Fobs
Modern key fobs now support features like remote start, climate control, and secure long-range communication. These require more power than coin cells can reliably deliver on their own. CAP-XX’s ultra-thin supercapacitors fit directly over the battery, enabling advanced functionality without increasing size, or replacing batteries more often.
Reduce Wiring Weight
Today’s vehicles contain over one mile of wiring. Supercapacitors placed near high-demand components (like blinkers, solenoids, or power seats) deliver the peak current locally, allowing thinner, lighter cables to be used elsewhere—reducing weight and improving fuel efficiency.
Enhance Audio Performance
High-end car audio systems demand stable, clean power, often over 200W per channel. Voltage fluctuations caused by cable impedance can degrade sound quality. CAP-XX supercapacitors hold the supply rail steady, eliminating harmonics and delivering consistent, high-fidelity performance.
Stabilise Vehicle Voltage
During stop-start engine cranking or sudden power loads, vehicle voltage can dip, causing malfunctions in critical electronics like EMS, GPS, and infotainment. Supercapacitors buffer these dips, keeping systems running smoothly without interruption.
Reliable Backup Power
In the event of a power failure, supercapacitors provide instant backup energy to critical safety systems, like airbag deployment or emergency e-call. With virtually unlimited cycle life and no maintenance, they offer a reliable safeguard for both the driver and the vehicle’s electronics.
Selecting Your Supercapacitor
Sizing the supercapacitor to your application is essential to maximise operation according to your required voltage and energy, package size and life constraints. With CAP-XX’s large range of supercapacitors, from 0.09F to 2.4F in our prismatic range and 1F to 3000F in cylindrical cans, we are able to meet whatever your application needs.
CAP-XX has a range of Application White Papers to assist customers’ design with supercapacitors. For more information please follow the link below.
