Course structure (explicit 5-unit plan)

Unit 1: Background of EVs

  • Historical context of hybrid and electric vehicles
  • How EVs developed and their current role
  • Social and environmental importance
  • Advantages and disadvantages
  • Types of EVs
  • India-related context:
    • Highly polluted cities (mentioned: “14 most polluted cities”)
    • Increase in oil imports from 1981 to 2015 (stated as “14× increase”)

Unit 2: Drivetrains and propulsion

  • Drivetrains and electrical traction drive topologies
  • Force/control concepts for:
    • DC drives
    • induction drives
  • Coverage of:
    • motors used in EVs
    • control systems

Unit 3: Energy storage and management (described as most important)

  • Why energy storage/management matters:
    • The battery is the “heart” of EVs
    • Challenges due to battery characteristics (e.g., weight/volume compared with ICE fuel tanks)
  • Inclusion of fuel cell storage and hydrogen for next-gen vehicles
  • Discussion of “epitita margins” (likely intended as economic/market performance or margins) for:
    • software & telematics
    • batteries
    • next-gen manufacturing
  • V2G and G2V fundamentals and concepts

Unit 4: Dynamics and charging

  • Forces required to drive an EV, including:
    • acceleration
    • braking
    • suspension-related behavior
  • Charging infrastructure topics:
    • economic aspects of charging infrastructure (“epitita margin” likely meaning cost/market sizing)
    • slow charging
    • fast charging
    • battery swapping technologies
    • standardization across countries (mentioned: India, China, US)

Unit 5: Selection and sizing of EV components

  • Matching/sizing concepts, such as:
    • matching electric machines with requirements vs IC (comparison stated)
    • selecting motor size/power
    • selecting energy storage technology based on EV sizing
  • Power electronics used in EVs (mentioned generally)

Why EVs are studied (motivations provided)

  • Environmental pollution and greenhouse gas emissions
    • EV motivation is tied to reducing environmental pollution.
    • Mentions global greenhouse gas emissions increasing since the 1990s, contributing to global warming.
    • Mentions regulatory pressure (e.g., “crab regulation,” likely referring to climate/regulatory constraints, in countries like India and China).
  • Energy security / oil dependence (India emphasis)
    • Mentions that oil imports have increased significantly (stated “14× from 1981 to 2015”).
    • Suggests reliance on imported oil (stated: “90%” imported) and declining oil reserves create challenges.
  • Increasing automobility and population growth
    • Mentions increasing number of automobiles and population planning challenges for countries.

Claimed benefits of EVs (and conditions noted)

  • Potential for reduced air pollution & emissions
    • Claims EVs can have zero tailpipe emissions.
    • Caveat: environmental benefit depends on the electricity generation source; if electricity comes from thermal power plants, greenhouse emissions can still occur.
  • Higher energy efficiency
    • EVs are said to be ~4× more efficient than ICE (diesel/petrol engines), based on the lecture’s comparison.
    • EVs have ~50× fewer moving parts than ICE, supporting higher efficiency and durability.
  • Lower operating/maintenance cost (implied by fewer moving parts)
    • Reduced moving parts → reduced maintenance expense.
  • Driving experience
    • Smooth, quiet drive due to instant torque and silent operation.

Key challenges for EV adoption (as stated)

  • Range anxiety
    • Limited driving range tied to concerns about charging infrastructure.
  • Charging infrastructure gap
    • EV charging network is lacking compared to existing ICE-related infrastructure.
    • Need for widespread charging stations.
  • Battery technology challenges
    • Need to address:
      • energy density
      • cost
      • lifespan
      • weight/volume
    • Battery characteristics are central because batteries are heavier/larger than fuel tanks for equivalent utility.
  • High upfront cost
    • EVs still have higher initial purchase cost than ICE vehicles.
    • Even with decreasing costs and government subsidies, consumers remain reluctant.
