Ultra Capacitors

A rapidly emerging and increasingly applied technology, ultracapacitors are capable of storing and discharging energy very quickly and effectively. Due to their many benefits, ultracapacitors are currently being utilized in thousands of different applications, and considered in an equally diverse range of future applications. Ultracapacitors complement a primary energy source which cannot repeatedly provide quick bursts of power, such as an internal combustion engine, fuel cell or battery. The future horizon looks brilliant for ultracapacitors, which already rank as a powerful alternative energy resource.

Ultracapacitor Modules

51 Volt Module

Our new 51V module is based on our industry-leading 48V module platform and includes the benefits of Maxwell’s proprietary DuraBlue® Advanced Shock and Vibration Technology. This new module features active balancing, Maxwell’s unique 2.85V cell technology, heat sinks on the top and bottom of the module, and an integrated fan for extreme duty cycle cases.

“NEW” 48 Volt Modules - With New, DuraBlue ® Technology

Our industry-leading 48V module now includes the benefits of our new DuraBlue® Advanced Shock and Vibration Technology.

16 Volt Small Module

Maxwell Technologies’ 16V small cell ultracapacitor module provides energy storage and power delivery in a compact, cost-effective module. The modules are specifically engineered to provide cost-effective solutions for wind turbine pitch control of 1.5MW and smaller, small UPS systems, telecommunications and other lighter-duty industrial electronics applications.

16 Volt Large Module

Maxwell Technologies’ 16V ultracapacitor module product line provides customers with a broad range of choices to meet their energy storage and power delivery requirements – in a rugged package that can be configured for higher voltages and energy if needed.

48 Volt Modules

Maxwell Technologies’ 48V ultracapacitor module product line provides customers in transportation and industrial industries with a broad range of choices to meet their energy storage and power delivery requirements.

56 Volt UPS Module

Maxwell Technologies’ 56V series of ultracapacitor modules provide power during dips, sags in the main power source. In longer term outages, the modules provide transition/bridge power to a longer term back up source such as a motor-generator or fuel cell. For industrial applications, ultracapacitor modules provide power for graceful shutdown of process equipment.

75 Volt Power Module

Maxwell Technologies’ 75V module is designed for low duty cycle energy storage applications such as wind turbine pitch control and backup power generation systems. The module includes passive balancing circuitry and thermal monitoring, and its enclosure meets the IP54 standard.

125 Volt Transportation Module

Maxwell Technologies’ 125V Heavy Transportation series of ultracapacitor modules is a high-performance energy storage product line for hybrid buses, trucks, trolleys, light rail, mining, construction and seaport cranes. Each model incorporates balancing, monitoring and thermal management capabilities to ensure industry-leading charge/discharge performance, high reliability and long operational life.

160 Volt Module

Maxwell Technologies’ 160V module is designed to provide energy storage and power delivery for wind turbine pitch control, short-term uninterrupted power supply (UPS) and renewable energy systems. Primarily designed for pitch control systems for 1.5 to 3MW wind turbines, the 160V module provides a turnkey solution to simplify the installation process and reduce costs for all integration partners.

Threaded/ Weldable Cells

The New K2 3.0V/3000F Cell

The newest addition to Maxwell Technologies’ K2 family of ultracapacitors is the 3-volt, 3000-farad cell. Maxwell’s first 3-volt cell meets the same life performance criteria as the 2.7-volt cell, with the added benefit of increased power capability a 31% increase over the 2.7-volt cell and a 15% increase over the 2.85-volt cell.

K2 2.85V/3400F Cell

The 2.85-volt, 3400-farad cell is Maxwell’s highest capacitance offering. Compared to the 2.7V/3000F cell, it has 17% more power and 23% more energy, making it an ideal choice for demanding applications. It also incorporates Maxwell’s DuraBlue® Advanced Shock and Vibration Technology. Products with DuraBlue technology are tested to some of the most demanding environmental requirements for transportation, increasing vibrational resistance by approximately three times and shock immunity by four times when com

K2 2.7V Series

Maxwell Technologies’ K2 2.7V series of ultracapacitors can relieve batteries from peak power functions, provide extended power availability, and help customers to reduce costs and maximize both space and energy efficiency in the overall system.

Board Mounted Small Cells

HC Series

The HC series is an ideal source of backup power. It can provide extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in a power supply or battery change. And, like all our ultracapacitor products, the HC series is capable of accepting charges at the identical rate of discharge.

D Cell Series

Maxwell Technologies' D Cell® series ultracapacitor cells are ideal for automotive boardnet stabilization, medical devices, uninterruptible power supplies, backup power and pulse, wind turbine pitch control, and many other applications requiring a pulse of energy that cannot be efficiently provided by a battery or power supply alone.
