Introduction to Electric & Hybrid Vehicles (Lesson 3 & 4)
What Are EVs and HEVs?
Goal: Save fuel and reduce pollution
EVs (Electric Vehicles) use electricity to move
HEVs (Hybrid Electric Vehicles) use both fuel and electricity
Types of HEVs
Full HEV (FHEV): Can drive short distances using electricity
Mild HEV (MHEV): Helps engine during start and stop, but can’t run on electricity alone
Plug-in HEV (PHEV): Can drive longer using only electricity and can charge with a plug
Micro HEV: Has start-stop system only
Main Features of HEVs
Electric motor helps the engine (gives more power)
Saves energy when braking
Some can drive using only electricity
Can charge battery while driving or by plugging in (PHEV)
Stops and starts engine at traffic lights
How HEVs Are Built
Power-split: More advanced mix with gear system
Series-Parallel: A mix of both
Series: Engine charges the battery, motor moves the car
Parallel: Engine and motor work together
Main Parts of HEVs
Battery Management: Keeps battery safe and working well
Motor: Moves the car
Battery: Stores energy
Charging Unit: Charges the battery
Inverter: Changes power from battery to motor
Control Unit: Controls motor and braking
