Battery Car

Yesterday evening, a 6-seater battery car was delivered in Eco Park. I trial drove it with Chief Engineer S P Chatterjee and others. Even while testing it, several visitors enquired if they could get a ride to reach back to their car park and what was the fare. You see, one needs to walk for an hour or two to travel once from one end of Eco Park to the other. Here is a photo - poor quality due to my mobile's flash not being effective:

Here is a cutting from today's Telegraph (Salt Lake):


  1. Kudos to NKDA for two great initiatives ! The battery operated eco-friendly vehicle will be very useful, particularly for the elderly. And it's a great to know that new town residents don't have to depend on Salt lake for swimming pool ! there should be programs for teaching swimming for beginners as well.

  2. Battery operated cars can be procured in larger numbers and should be given as a paid service if there is demand. This can be a way for increasing revenue.

  3. Debasish da I am staying in Sunrise Point at Action areas IIC any update on We badly need it along with bus service.

    I have great faith on you hope to see this soon.

  4. Debasish da another issue is we found every day morning a large number of trucks standing at akhanka more its really problem for us to drive through that way can't they put in under a terminal nearby.

  5. There would be a re-tender for the AA-IIC community market tender (see NKDA website).

  6. Yes, Soumik, there will be re-tender soon.

  7. Sir can you consider turning the road between Technopolis to Unitech or Akangsha in Electric Road.
    Here's a report.

    First 'electric' road charges buses in S Korea

    SEOUL: In a first, South Korea has developed a hi-tech 'electrified' road which can recharge moving electric vehicles as they drive over it.

    Project developers claim that the 12 kilometre route is the first of its kind in the world and allows electric public buses to recharge their batteries from buried cables as they travel. The Online Electric Vehicle (OLEV) is an electric vehicle that can be charged while stationary or driving, thus removing the need to stop at a charging station, researchers said.

    OLEV, developed by the Korea Advanced Institute of Science and Technology (KAIST), does not require pantographs to feed power from electric wires strung above the tram route.

    Two OLEV buses run in an inner city route between Gumi Train Station and Indong district, for a total of 24km roundtrip.

    The bus receives 20 kHz and 100 kW (136 horsepower) electricity at an 85 per cent maximum power transmission efficiency rate while maintaining a 17cm air gap between the underbody of the vehicle and the road surface. OLEV receives power wirelessly through the application of the Shaped Magnetic Field in Resonance (SMFIR) technology.

    SMFIR is a new technology that enables electric vehicles to transfer electricity wirelessly from the road surface while moving.

    Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity.

    The length of power strips installed under the road is generally 5-15 per cent of the entire road, requiring only a few sections of the road to be rebuilt with the embedded cables.

    The road has a smart function as well, to distinguish OLEV buses from regular cars - the segment technology is employed to control the power supply by switching on the power strip when OLEV buses pass along, but switching it off for other vehicles, researchers said.

    "This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living," Dong-Ho Cho, a professor of the electrical engineering at KAIST, said.

    1. Thanks Sir for your interest in Electric Road.
      Initially can you please try to change the road from HIDCO to UNITECH.(may be 3 km). Though the cost will be high but running cost will be much low.
      Also Sir, can you please think of a moving platform in the same sector.People can just hop into one of them by paying Rs 5.Then the auto_rickshaw may be avoided(Which takes lots of road space.) In such a huge traffic flow the cost may be recovverred in 3 years.
