Study Notes
Electric Mobility
- Reducing oil dependency (self-sustainable)
- Efficient use of Energy: Electric Vehicle efficiency > Internal Combustion Engines (ICE)
Electric Vehicle Definition
- A vehicle powered by an electric motor that draws electricity from a battery and is capable of being charged from an external source
- Powered exclusively by an electric motor whose traction energy is supplied exclusively by a traction battery installed in the vehicle
Types of EV
- Plug-in Hybrid Electric Vehicle (PHEV)
- Battery Electric Vehicle (BEV)
- Hybrid Electric Vehicle (HEV)
- Fuel Cell Electric Vehicle (FCEV)
EV vs ICE
- EV: 40-60% conversion efficiency, >90% efficient
- ICE: 40-60% conversion efficiency, <90% efficient
Emissions
- EV: 0-50 g/km tailpipe emissions
- ICE: 120 g/km tailpipe emissions
Sustainable Energy
- Reducing fossil fuel dependence
- Increasing use of renewable energy sources
- Electric mobility as a key component of a sustainable energy pathway
Concerns Regarding Battery Powered EV
- Driving range
- Lack of charging infrastructure
- Cost
- Time required to charge
- Safety concerns
- Lack of choice
Battery Electric Vehicle (BEV)
- Examples: Porsche Taycan, Porsche Taycan 4S, Porsche Taycan Turbo, Porsche Taycan Turbo S
- Key specifications: motor type, power, torque, range, charging time
Why Electric Mobility?
- Regulation: need to reduce Earth's temperature rise by 2°C by 2050
- Consumer behavior: changing awareness and acceptance of sustainable mobility modes
- Technology: accelerated improvements in electric mobility, autonomous, and shared mobility
