Emerging Trends In Electric Mobility

ARAI VIEW: Mrs. Rashmi Urdhwareshe – Director (Chief Guest) & Mr. Anand Deshpande – Sr. Dy. Director ARAI.

Government policies in-line with Paris Agreement to reduce pollution, temperature and greenhouse gases.

• Drivers to get converted to EV.
  • Paris Agreement.
  • Ambient air quality requirements in major cities of India.
  • Oil Import reduction to control CAD.

Rest of the things government is working on:

1. Boost solar power.
2. E-Corridors for CV.
3. Support to Power Electronics Sector.
4. Light weight automotive products.
5. Encourage localization of EV Components.
6. Battery Management and Cooling Systems.
7. IOT: Internet of things.

Challenges in EV:

1. Component sizing and specification.
2. Motor – efficiency, performance & durability.
3. Battery – cycle life, safety & BMS
4. Charging Stations – Rollout, Interoperability, weather proof & Safety.

ARAI is equipped with Chargers, Charging Know how and Testing capabilities for EV Components and EV’s.

• EV Busses Intracity are subsidized by Govt. Targeting 10000 EV Buses by 2022.
• Buses, 3Wh & 2 Wh are prime candidates for EV.
• AL has 2 Options already – CIRCUIT F & S (F=fast charge & S = Swap model).
• Buses already plying in Ahmedabad with new orders from Chennai.
• AL is working on Flash Charge tech – Charging in 5 Mins. Tech is currently not feasible on commercial grounds.

RAVI DAMODARAN – CTO – Greaves Cotton LTD.

1. His view is that before we get to complete EV from Fossil fuel – interim step will be Hybrids.
2. He also suggested use of Methane (Bio Gas) before we can go to EV.
3. Due to EV – Forging & Machining components will be vastly reduced. Castings can still be used.
4. His view was that Lithium Batteries are not good for India as they are designed for low temperature operating ranges 15~20 Degrees.

Systems with strong localisation initiatives will be : Electric AC compressor, Power electronics, Telematics, Remote diagnostics solutions, End of line testing for battery / e-drive / power electronics system.

Changeover from current IC engines (ICE) to EV will be as below :

1. 2 Wheeler : IC engine >> Batter EV
2. 3 Wheeler : IC engine >> Hybrid CNG >> Batter EV
3. PV Cars : IC engine >> Micro Hybrid >> Mild Hybrid >> Strong Hybrid >> Fully Hybrid / PHEV >> Range Extender >> FULL EV. ( Till 2030 India may achieve 100% EV in PV Car Segment )

By 2030 approx. 24% vehicles will be all electric – ICE will vanish in these 24% Vehicles.

2W EV : Frame motor and Hub motor are the two types of motors used. At present Hub motor is preferred even though having efficiency is poor. In future Frame motor will be used considering efficiency.

In EV: Weight and Cost – up, Range – Down. VW Polo – 1200 Kg for diesel car / eGolf – 1540 Kg for full EV.

 Dr. HEMANT IYER ( Materials Scientists Aditya Birla Science & Technology Company Pvt Ltd )

As the battery weight is not possible to reduce much the focus would be on reduction of rest of the vehicle weight.

He mentioned about – Graphene – material discovered in 2010 & which won a Noble Prize. It is made from single cell configuration of Carbon atom, its stronger than steel by approx. 200% & 6 times lighter by weight.

Connected Cars that will communicate with Chargers, other cars, passengers, traffic and scenarios arising from the same. AI will play a very vital role going ahead in all the dynamics & so will cyber-security. The driver will now become a passenger.

ALOK DAS (MD – REVOLT MOTORS.)

He highlighted following:

1. Highest contributors to worlds Green House gases are US, China and India. India contributes up to 6% of all greenhouse gases.
2. Paris Agreement, Indian dependency on oil also driving this EV scenario.
3. Rising population and pollution – 14 of 15 worlds most polluted cities are in India.

He cited case studies done in Norway, US & China – where most of the EV’s are sold in the world.

The conclusions from these case studies are as follows:

1. EV’s penetrated in countries where the govt drive was strong.
2. Most people charge cars at home at night – public charging infra is used rarely & not a deterrent to buy EV.
3. Average public charging stations in these countries are 1:15 ~17 vehicles. In Norway it is 1:28.
4. Expensive operational cost on ICE Vehicles also pushes consumers towards EV.
