Opportunity Snapshot

Automotive Supercapacitor Market Growth Drivers and Impact Analysis

Electrified Powertrains Need High-Power Buffering

Electric cars necessitate power components that will be able to absorb and discharge energy at a quicker rate compared to the batteries when accelerating, decelerating, and accessing accessories. The supercapacitors play this role by ensuring reduced peak loads on the battery packs and enhanced energy recovery and voltage stabilization. With the increase in sales of electric cars, there is pressure on the OEMs to enhance efficiency, longevity, and economics of their warranties. This pressure is felt most in cities and performance vehicles due to frequent decelerations and demands for transient power.

Start-Stop and 48V Systems Expand Addressable Demand

Start-stop and 48V Mild Hybrid systems pose practical requirements for the use of supercapacitors due to the necessity for fast discharging, charging, and longevity. Ordinary batteries can perform such operations, however, numerous cycles of high current usage speed up their degradation. Start-stop and 48V systems using supercapacitors increase the reliability of restarts and eliminate drops in electricity usage, as well as provide an opportunity for manufacturers to achieve the necessary fuel economy levels without changing the vehicle into a full-electric one.

Commercial Fleets Prioritize Uptime and Lifecycle Cost

Since commercial vehicles go through repetitive cycles of braking, idling, loading, and auxiliary power, they become ideal candidates for supercapacitors. In the fleet industry, technologies are judged on the basis of uptime, maintenance savings, and payback period, as opposed to novel parts. Supercapacitors can enable regenerative braking, cold start, liftgate load, and power flattening. The implications will be particularly pertinent in buses, vans, refuse trucks, and port vehicles. In an age of increasing electrification of fleets, vendors who exhibit robustness in tough duty cycles will be able to turn pilot programs into platforms.

Automotive Supercapacitor Market Future Trends

Hybrid Capacitor Architectures Move Toward Platform Design

Automotive Supercapacitors Market Trends are moving towards hybrid design concepts which help achieve high energy densities along with fast charging capabilities. These trends will become important for OEMs who require small size modules that complement the battery systems but do not add extra weight or thermal issues. Future products will incorporate better electronics, enhanced electrode design, and packaging optimized for vehicle platforms. It will lead to greater use of supercapacitors in electric and hybrid vehicles.

Localized Supply Chains Become a Procurement Priority

Vehicle manufacturers will be encouraged to source supercapacitors locally due to the impact that geopolitical risks, limitations on materials for batteries, and lack of electronic components will have on purchasing. Local manufacturing will allow for shorter qualification periods and less logistics risk, and will also be aligned with incentive programs related to local production. This could present opportunities for suppliers that are based in multiple regions, have automotive-level manufacturing capability, and are located near EV assembly plants.
