Types of powertrain
Types of Powertrain

NB: All stated efficiencies are “Tank to Wheel”, NOT “Well to wheel”. For EVs, implies “plug to wheel”, not “power plant to wheel”

Eu s targets
EU’s targets

EU’s target is to reduce emissions from 1990 levels by 20 % by 2020

EU’s target (CO2 emissions) for

  • a new passenger car is

    130 g/km at 2015

    95 g/km at 2020

  • a new van is

    175 g/km at 2017

    147 g/km at 2020

    EU is aiming to increase the share of the renewable energy to 20% of the final energy consumption by 2020

Arska is hydrogenguytoo

Oil is easyanswer

  • Efficiency in electric cars is 85% (30-32%) when in petrol cars its 20-25%

    Energies that some batteries can hold:

    • Lead battery 20-40 Wh/kg

    • Lithium-ion battery 70-130 Wh/kg

    • Petrol can hold about 12 000 Wh/kg

  • Companies are developing new and better batteries so electric cars can run longer

    Today most used batteries are lithium and lead batteries

  • To load batteries it takes many hours but new technology is developing that can charge electric cars lot faster

  • Electric cars with lead batteries can travel up to 100 km

    With new lithium-ion batteries cars can travel 160 km

  • Hybrids

    Hybrid electric vehicles (HEVs) use petroleum engine and at least one electric motor

    Petroleum engine produces energy for propulsion, other technical solutions recycle the energy

    Batteries store extra energy and electric motor transforms it to thrust

    Generative breaking and constant engine drive recharge batteries

    Other green solutions as automatic engine stop and start when not moving are also common in HEVs

    On low velocities all HEV’s thrust is provided by the electric motor

    Parallel use of engine and motor reduces fuel consumption and emissions


    • =Kinetic Energy Recycling System

    • Used in Formula 1 and othermotorsports

    • Energy canbestoredeither as

      • mechanicalenergy as in a flywheel

      • electricalenergy as in a battery

    • Extra 60 kW available for 6.67 seconds per lap

      Benefit per lap is approximately 0.1 to 0.4 seconds

    • Has a badreputationbecause of highpricetag for smallgain,inreliability and electricshocks
