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 compact HV4WD E-Four used for the Prius adds little weight and does not reduce the fuel economy or interior storage. A few weeks before the November 2018 Los Angeles Auto Show , Toyota issued a press release with text and images featuring the car in snowy conditions, suggesting the E-Four package would likely debut in the 2019 U.S. model at ...
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 ...
gradual braking: Regenerative brakes re-use the energy of braking, but cannot absorb energy as fast as conventional brakes. Gradual braking recovers energy for re-use, boosting mileage; hard braking wastes the energy as heat, just as for a conventional car.
Brake-by-wire technology has been widely commercialized with the introduction of Battery Electric Vehicles and Hybrid Vehicles. The most widely used application by Toyota in the high volume Prius was preceded by the GM EV1, the Rav4 EV, and other EVs where the technology is required for regenerative braking. Ford, General Motors, and most other ...

A start-stop system off button on a Perodua Myvi. A vehicle start-stop system or stop-start system (also known as S&S, micro hybrid, or micro hybrid electric vehicle (μHEV)) [1] automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
