Functions of Supercapacitor Modules & Supercapacitor Systems

  • Modular Flexibility

    Supercapacitor modules are designed for modularity, offering exceptional flexibility for expansion and customization to meet diverse energy and power needs across various applications. This modular design allows users to configure modules in series to achieve higher voltages or in parallel to increase capacitance, tailoring the system to specific requirements. Supercapacitor modules can be customized using a sizing calculator to determine the optimal configuration based on discharge type (constant power or current), power needs, and operational conditions. This adaptability makes them suitable for applications ranging from small-scale electronics to large-scale systems like electric buses, trams, and grid energy storage. The ability to integrate seamlessly with other energy storage technologies, such as batteries in hybrid energy storage systems (HESS), further enhances their versatility, optimizing cost, performance, and system longevity.


  • Enhanced Power Output

    Supercapacitor modules deliver instant high power output, making them ideal for demanding applications that require rapid energy bursts, such as electric vehicle startups and regenerative braking. Applications like Mazda’s i-eloop system and the Toyota Yaris Hybrid-R concept demonstrate how supercapacitor modules provide power boosts for acceleration and stabilize electrical systems, contributing to fuel savings of up to 10%. Their low equivalent series resistance (ESR) ensures minimal energy loss, making them a superior choice over standard modules for high-power applications like active suspension systems and industrial robotics.


  • Advanced Safety Features

    Supercapacitor modules incorporate intelligent management systems (SMS) for real-time monitoring, significantly enhancing safety and reliability compared to traditional energy storage systems. These systems actively monitor cell states, including voltage, temperature, and charge levels, to ensure optimal performance and prevent issues like overcharging or thermal runaway. Unlike batteries, which can overheat or explode when short-circuited, supercapacitors have inherently low internal resistance, reducing heat generation and improving safety.

Applications of Supercapacitor Modules

Supercapacitor Modules in Automotive and Transportation


Supercapacitor modules are critical in electric vehicles (EVs), hybrid cars, and public transit systems like buses and trams. They support regenerative braking, capturing up to 55% more energy than batteries during deceleration, which is reused for acceleration or auxiliary systems. For example, Maxwell Technologies’ supercap modules in hybrid buses enhance fuel efficiency by 10–15% in urban settings.


Supercapacitor Modules in Grid Energy Storage


Supercapacitor modules stabilize power grids by addressing short-term fluctuations in energy demand within milliseconds. They are vital in renewable energy systems, smoothing out solar and wind power intermittency for frequency regulation and peak shaving.


Supercapacitor Modules in Industrial Uses


In industrial settings, supercap modules power heavy machinery, robotics, and material handling equipment like forklifts and AGVs, enabling rapid acceleration and energy recovery. They support wind turbine pitch control for precise blade adjustments and power cranes for lifting operations, reducing strain on primary sources. Their durability ensures reliable performance in harsh industrial environments, making them a preferred choice for high-power applications.

Advantages of Supercapacitor Modules

High Power Density


Supercapacitor modules deliver exceptional power density, often exceeding 10 kW/kg, compared to 1–3 kW/kg for lithium-ion batteries. This enables rapid, high-intensity energy bursts for applications like electric vehicle acceleration and regenerative braking. Their low equivalent series resistance (ESR) minimizes energy loss, ensuring efficient power delivery in industrial robotics or grid stabilization, where quick response times are critical.


Long Cycle Life


Unlike batteries, which degrade due to chemical wear, supercap modules achieve over one million charge-discharge cycles with minimal performance loss. This longevity reduces maintenance costs and enhances cost-effectiveness in applications with frequent cycling, such as public transit or UPS systems.


Wide Operating Temperature


Supercapacitor modules function effectively across a broad temperature range, typically from –40 °C to +85 °C, making them versatile for extreme environments. They perform reliably in aerospace applications under sub-zero conditions or in desert-based solar farms with high temperatures. This thermal resilience ensures consistent energy delivery in harsh industrial settings, outdoor grid installations, and automotive systems exposed to variable climates, outperforming batteries that may fail under such conditions.
