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
This quiz covers increasing energy security by reducing oil dependency and efficient use of energy, comparing Internal Combustion Engine (ICE) and Electric Vehicle (EV) efficiency.
