The company said, K2 series Boostcap cells are about the size of a soda can, and can operate at 2.7v and incorporate design and construction enhancements to ensure durability and long operating lifetime.
Primary applications for Maxwell’s K2 series products, which range from 650 to 3,000 farads, include automotive subsystems, hybrid and electric vehicle drive trains, renewable energy systems, back-up power, grid stabilization, electric rail system power and many other transportation and industrial applications that require burst power and heavy cycling that cannot be efficiently provided by a battery or power supply alone.
The company is currently shipping K2 cells in production volumes and multi-cell modules ranging from 16- to 125v. The K2 cell design features a rugged welded electrical pathway with increased contact and higher surface area. The K2 replaces Maxwell’s previous MC series cell. Boostcap ultracapacitor cells and multi-cell modules are suitable for consumer and industrial electronics, transportation and telecommunications applications.
According to the company, features of the K2 series ultracapacitor cells include ultra-low internal resistance, low resistor–capacitor (RC) time constant, over one-million charge/discharge cycle lifetime, capacity to perform at extreme temperatures and proprietary material science and packaging technology.
Maxwell manufactures and markets additional Boostcap ultracapacitor products ranging from 10 to 350 farads and multi-cell modules based on those products for wind turbines, smart utility meters and a variety of other industrial, telecommunications, information technology and other applications.
David Schramm, president and CEO of Maxwell, said: “Rapidly increasing demand for large cell products provided the impetus for development of an enhanced cell platform that meets the most demanding electrical and environment requirements for a variety of applications and is well-suited for high-volume production.
“The K2 cell offers greatly enhanced mechanical robustness and low resistance for longer cell life and increased electrical performance.”
