Engine braking: The HSD system has a special transmission setting labelled 'B' (for Brake), that takes the place of a conventional automatic transmission's 'L' setting, providing engine braking on hills. This can be manually selected in place of regenerative braking.
Regenerative braking has a similar energy equation to the equation for the mechanical flywheel. Regenerative braking is a two-step process involving the motor/generator and the battery. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery.
Regenerative braking – The drive motor becomes a generator and recovers energy by converting kinetic to electrical energy, also slowing the vehicle and preventing thermal losses. In addition: May be plugged into the grid to recharge the battery. Supercapacitors assist the battery and recover most energy from braking.
The battery control computers keep the state of charge (SoC) between approximately 40% and 80% (shallow cycling), where the average SoC hovers around 60 percent, allowing about 400 Wh of useful energy storage to capture energy from regenerative braking and to release it back into the hybrid drive-train through Motor-generator 1 and Motor ...
The Volt gets 38 miles of all-electric range, the Prius Prime is rated for 39 (44 with smaller wheels). How did we go so damn long with only minimal improvements on the original PHEV formula?
At least that's what U.S. regulators are concerned about after receiving reports from owners of newly purchased 2010 Prius models who have experienced problems stopping on slippery or bumpy roads ...
Hybrid-electric vehicles (HEVs) combine the advantage of gasoline engines and electric motors. The key areas for efficiency or performance gains are regenerative braking, dual power sources, and less idling. [108] Regenerative braking. The electric motor normally converts electricity into physical motion.
The Prius liftback is the top-selling model with 1,812,800 units, ... Regenerative braking can be used to recapture energy and stored to power electrical accessories ...
