The XLR supercapacitor module from Eaton is a 166F energy-storage device which offers high power capability and the high reliability required in automotive applications.

Eaton supercapacitors use an Electrochemical Double-Layer Capacitor (EDLC) construction combined with proprietary materials and processes. The 166F XLR supercapacitor module is housed in a rugged 177mm x 421mm x 196mm package, and weighs 14.7kg.

An Eaton supercapacitor may be used as an energy-storage device on its own, or in combination with batteries to extend their lifespan and run-time. The XLR module is particularly suitable for use in commercial electric vehicles, such as buses, trucks and forklifts. Here, a battery-supercapacitor hybrid design can help to extend the life of a lithium or lead-acid battery: the supercap more effectively handles demand for high-current pulses than a battery, and so reduces stress on the battery when the load on the system peaks. Eaton has developed an automotive simulation tool to help evaluate the performance of the XLR supercapacitor in any given drive cycle.

The XLR supercapacitor has a peak power rating of 118kW and can supply a pulse current of up to 2.2kA for up to 1s. Maximum continuous current is 86A.
