Eaton XLR-51 supercapacitor module for rugged applications

The XLR-51 supercapacitor module, from Eaton, extends the XLR module family to 51.3 V and 188 F. It is suitable for rugged applications in harsh environments, such as transportation, marine, grid storage and material handling.

The supercapacitor module is designed to provide efficient energy storage for high power, high charge/discharge and peak power shaving applications and to improve power quality for voltage spikes and brownouts for backup power applications. Each module includes an integrated cell voltage management circuitry, an overvoltage alarm and a temperature output.

UN-ECE Reg 10 and Reg 100 certifications have been achieved on the 48 and 51 V XLR modules. The scope of these standards governs provisions for wheeled vehicle electromagnetic compatibility for Reg 10 and specific environmental requirements for integration into electric power trains (ie, electric vehicles) for Reg 100.

The XLR supercapacitor module is a self-contained energy storage device comprising 18 individual XL60 supercapacitor cells. It is RoHS compliant and requires no external battery management system (BMS) due to Eaton’s cell balancing technology. With up to a 20-year lifespan, the module is said to increase the life of primary transportation energy storage systems by reducing the need for replacement parts and batteries.
