A More Electrified hybrid

Hymotion Plug-in Conversion Modules increase the electric capability of the Prius hybrid platform by supplementing the vehicle's factory battery. The Hymotion module's greater stored energy capacity allows the Prius to use electric drive more often and for longer distances, engaging the gas engine less frequently and resulting in large fuel efficiency gains over the stock Toyota Prius.

A123's Hymotion modules are based on our Nanophosphate™ lithium ion batteries that deliver higher levels of power, safety, and life than conventional lithium ion batteries.

Rechargeable energy

The Hymotion L5 Plug-in Conversion Module is a rechargeable Nanophosphate™ lithium ion battery that uses regular 120V grid power to recharge, providing the user with ~5kWh of rechargeable energy storage at full capacity.

Through the increased use of electric drive, the Hymotion Plug-in Conversion Module enables the Prius to achieve in excess of up to 100 mpg for 30-40 miles* over a range of up to 40 miles, dependent upon driving conditions. Once the L5 module is depleted, the vehicle reverts to the normal drive cycle of a stock Toyota Prius.

Hymotion plug-in hybrids save more energy and produce less pollution than standard hybrids on the road today.

Drive longer / Drive Better

The L5 module provides more frequent periods of all-electric driving during your commute, but the L5 module does not block the gas engine from engaging while the pack has charge. When the Prius needs power, either dictated by your right foot, or by driving conditions like hills, the gas engine will engage to supply that power.

In that sense, complete electric driving is limited by the current configuration of the Toyota Prius. But that does not keep you from enjoying fuel economy of up to 100 mpg for 30-40 miles*! To learn more, check out our performance data.
