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.
- Need to address:
- High upfront cost
- EVs still have higher initial purchase cost than ICE vehicles.
- Even with decreasing costs and government subsidies, consumers remain reluctant.
