Maxwell Technologies Inc., a developer and manufacturer of ultracapacitor-based energy storage and power delivery solutions, announced the 51-volt (51V) module — the newest addition to its ultracapacitor product offerings for rugged applications. The 51V module uses Maxwell's leading 2.85V, 3,400-farad ultracapacitor cell to deliver the company's highest energy and power density available today.

As durable and efficient energy storage solutions are in strong market demand, Maxwell's 51V module provides a self-cooling system solution that helps to optimize the performance of hybrid buses and other high-duty cycle applications.

Additional features of the 51V include:

• Incorporates Maxwell's proprietary DuraBlue™ Advanced Shock and Vibration Technology into the design, which provides three times the vibrational resistance and four times the shock immunity of previous ultracapacitor-based competitive offerings.

• Meets and exceeds the industry's highest vibration standard for ultracapacitor modules and has an IP65 environmental protection rating, ensuring the module is not impacted by dust and water.

• Includes an active cooling system, which improves the module's maximum continuous current rating by nearly 90% and ensures optimal performance even in extreme temperatures, down to minus 40 degrees and up to 65 degrees Celsius.

• Has an identical mounting pattern to Maxwell's current 48V module.

"Hybrid bus systems need to perform reliably, even when exposed to harsh conditions such as rugged roads and extreme temperatures. The 51-volt module's ability to perform during demanding high duty-cycle applications reinforces our ongoing commitment to deliver superior performance and value to our customers," said Dr. Henning Hauenstein, VP, strategy and marketing of Maxwell Technologies.
