As Rusty notes, you can drive with the engine off quite frequently, so long as you let the battery
recharge under braking.
The batteries are
recharged under braking and when the electric motor is generating excess torque (during cornering, for example).
Not exact matches
Generally the battery is only
recharged when the driver is off the throttle, for example, when coasting or
under braking.
Brake Energy Regeneration collects energy on overrun or
under braking to
recharge the vehicle's battery, allowing the absolute maximum engine power be delivered to acceleration rather than being diverted to power electrical systems.
Further gains are made
under braking, as Porsche has engineered the system so that the battery can be
recharged through the process of
brake energy recovery known as recuperation.
Under acceleration the mild hybrid system provides up to 10kW of electric power assistance to the powertrain in «motor» mode, while in «generator» mode, the system harvests kinetic energy from the vehicle during in - gear deceleration and
braking and uses the power to
recharge the batteries.
Recharging the battery is performed both on the run using kinetic energy created
under braking and coasting and by plug - in means via an 800V electric architecture.
Regenerative
braking recharges the battery pack located
under the rear bench seat.
The concept behind one - pedal driving is that as the driver lets up on the accelerator, the drivetrain's regenerative
braking system — which
recharges the battery as the car slows — engages, just as it does
under a light touch of the
brake pedal.
The Niro Plug - in Hybrid features regenerative
braking technology to harvest kinetic energy and
recharge the battery pack while coasting or
braking, while a new Eco Driving Assistant System (Eco DAS) provides drivers with intelligent guidance on how to drive more efficiently
under current conditions.
So the alternator
recharges, predominately,
under braking or at any time the accelerator is relieved.
The
braking system is completely integrated with all the other vehicle dynamics systems so that the hybrid system goes into regenerative
braking mode which guarantees that the batteries are
recharged even
under very hard
braking with the ABS active.
In case this means absolutely nothing to you, KERS acts like a boost button which
recharges using energy created
under braking.
