Maxwell Technologies introduces its newest member of its K2 family of ultracapacitors, the 2.85-Volt, 3,400-Farad cell. It expands the power range of the K2 family by 17% and the energy range by 23%, making it the most powerful cell available in the industry-standard 60-mm cylindrical form factor. It is the first cell to incorporate Maxwell’s DuraBlue Advanced Shock and Vibration technology.
DuraBlue technology is tested to demanding environmental requirements for transportation, increasing vibrational resistance by about 300% and shock immunity by 400% when compared to ultracapacitor-based competitive offerings.
Features and benefits include:
- Up to 1,000,000 duty cycles or 10 year dc life
- Highest power and energy
- Up to 18 kW/kg of specific power
- Up to 4.00 Wh of stored energy
- Threaded terminals or laser-weldable posts
The K2 family provides electrostatic storage that can cycle a million charges and discharges without performance degradation. They are available in quick and easy to implement threaded terminals or in compact, weldable terminals.
These cells are ideal for transportation applications, including public transit vehicles and heavy transportation, where the shock and vibration environments are the most severe. They also provide extended power and energy availability for longer periods of propulsion in automotive subsystems. They provide faster response for critical information in UPS/Backup Power applications and in grid applications to enable critical information to remain available during dips, sags, and outages in the main power source. In addition, they can relieve batteries of burst power functions, thereby reducing costs and maximizing space and energy efficiency.
The K2 family of cells work in tandem with batteries for applications that require a constant power discharge for continual function and a pulse power for peak loads. In these applications, the ultracapacitor relieves batteries of peak power functions resulting in an extension of battery life and a reduction of overall battery size and cost.
In applications where power is needed in spikes, the K2 family provides a “green” power solution to reduce peak power demands on the grid, batteries or generators. And, like all Maxwell ultracapacitors, the K2 series is capable of accepting charges at the identical rate of discharge. Models include the BCAP3400 P285 K04 and BCAP3400 P285 K05.
