Maxwell Technologies unveils 51-volt ultracapacitor module for hybrid buses

Ultracapacitor specialist Maxwell Technologies has introduced a 51-volt module that’s specially designed for use in hybrid buses and other high-duty cycle applications. The latest addition to Maxwell’s lineup features a 2.85 V, 3,400-farad ultracapacitor cell that delivers the company’s highest available energy and power density.

Maxwell’s 51 V module includes an active cooling system, which is designed to ensure optimal performance from -40° to 65° C, and improves its continuous current rating by nearly 90%. It also incorporates Maxwell’s proprietary DuraBlue Advanced Shock and Vibration Technology. It exceeds the industry’s highest vibration standard for ultracapacitor modules (ISO 16750-3, Table 12), and has an IP65 environmental protection rating. It has an identical mounting pattern to Maxwell’s current 48 V module.

“Hybrid bus systems need to perform reliably, even when exposed to harsh conditions such as rugged roads and extreme temperatures,” said Maxwell VP Dr. Henning Hauenstein. “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.”
