Electric & Hybrid Vehicles L03/L04
EV (Electric Vehicles)
Uses one or more propulsion in electric or traction motors
BEV (Battery electric vehicles)
Uses battery for propulsion
PHEV (Plug-in hybrid electric vehicle)
Can be charged to external charging outlets
Larger battery
Can drive mainly on electric in EV mode 30-100km
HEV Configuration
Axle split parallel hybrid : axle-split parallel hybrid, the combustion engine (ICE) drives the front axle while the other, rear, allowing vehicle to operate in fully electric mode or engine only or even both for AWD (all-wheel drive).
Parallel hybrid with double clutch transmission : uses 2 clutches allowing to switch gears much more quickly, odd (1,3..) and even gears (2,4..) where the system automatically switches between fully electric mode only, engine only or acts as a hybrid which is both mode running concurrently.
Parallel hybrid with 1 or 2 clutches : both the engine (internal combustion engine, ICE) and electric motor can move the vehicle either as its own or altogether, meaning it has 2 power sources either by internal combustion engine or the electric motor. One clutch: fewer parts, making it simpler to control. Two clutches: Separated from electric motor and ICE power sources, more flexibility
FHEV (Fully hybrid electric vehicle)
Cannot be charged to external outlets
Uses regenerative braking to generate power with the use of ICE (internal combustion engine)
Can drive mainly on electric unlike MHEV which requires it
Series hybrid
ICE powers the alternator/generator to provide charge to the battery for its torque assistance (fill and boost, these can be turn into electrical flow to provide power in charging battery or direct source of power to the electric motor, driving the wheels
Series Parallel hybrid
Combination of series and parallel, combustion engine can drive wheels directly similarly to parallel hybrid or produce electricity to the motor similarly to series hybrid: motor drives the wheel (electric mode only), ICE drives the wheel (engine mode only), both motor and the combustion engine works together as a hybrid mode or series mode where electricity is produced in driving the wheels.
