MAXWELL, represented in Australia by Glyn , has launched the first of a new family of large cell Boostcap ultra-capacitor cells and multi-cell modules. Based on a technology breakthrough that enables them to store more energy and deliver more power per unit volume, the Boostcap is designed to last longer than any other commercially available ultra capacitor product.
The 2.7V Boostcap MC2600 2600 farad large cell and fully integrated BMOD2600-16, 16V module incorporates six MC2600 cells and according to Glyn, establishes new industry standards for performance and price.
These new products meet or exceed demanding automotive application requirements for both watt-hours of energy storage and watts of power delivery per kilogram and will perform for more than one million discharge-recharge cycles at 2.7V. The proprietary technology on which they are based also reduces material and production costs.
The new family of large cells and multi-cell modules are specifically designed ‘with the user in mind’ to provide versatile, durable, compact and low-cost solutions for strategic transportation and industrial applications.
The cylindrical MC2600 cells, constructed of lightweight aluminium and Maxwell’s proprietary electrode, measure 166mm in length, 57.7mm in diameter and weigh 470 grams. They feature a double-ended design that is available in two versions that facilitate either mechanical or welded termination.
The BMOD2600-16 modules are encased in a rugged, splash-proof, aluminium chassis. They weigh 5kg and are less than 4.85L in volume (420mm x 160mm x 70mm). These durable ‘smart boxes’ include temperature and voltage monitoring and internal cell balancing that give designers plug and play solutions, plus module-to-module balancing making them versatile building blocks for systems with higher voltage requirements.
Boostcap ultra capacitors deliver up to 10 times the power and longevity of batteries and require no maintenance and operate reliably in extreme temperatures. In transportation applications, they efficiently recapture energy from braking for reuse in hybrid drive trains, reducing fuel consumption and emissions. They provide compact, lightweight, ‘life-of-the vehicle’ solutions to stabilise automotive power networks and power new, all-electric subsystems, such as drive-by-wire steering.
In mission critical industrial applications, where backup power is critical for continued operation or a soft shutdown in the event of power interruptions, the ultra-capacitors provide reliable, maintenance-free energy storage. In wind turbine blade pitch and braking systems and other industrial applications, they provide a simple, solid state solution to buffer short-term mismatches between the power available and the power required.
