When you couple ultracapacitors with lithium batteries performance of an electric vehicle is dramatically boosted. Ultracapacitors give electric vehicles the instant response needed to get going, recover braking energy, work across a wide temperature range, and charge very quickly for thousands or millions of cycles.  There is more out there than Eestor, and some are […]

The researchers at the Department of Energy’s Oak Ridge National Laboratory have designed, fabricated and demonstrated a PHEV traction drive power electronics system that provides significant mobile power generation and vehicle-to-grid support capabilities. (The Oak Ridge press release isn’t specific, but here PHEV seems to mean Plugin Hybrid Electric Vehicle, not parallel hybrid EV.)  The […]
