Khammam: With the alarming increase in gasoline and diesel, many are turning to electric bicycles and cars, which have recently been gaining popularity with the public across the country.

Taking inspiration from the market trend, a B Tech graduate from Khammam has designed an upgraded electric car that can deliver a range of around 300 kilometers with fully charged batteries. The operating cost to cover this distance will be around Rs 20 to 30, to charge the batteries.

“The vehicle that I developed is basically a redesigned vintage car model fitted with an electric motor and batteries to power the car. Rs 3 lakh is spent to manufacture the car,” said Garlapati Rakesh, who made his B Tech in Mechanical Engineering, at Telangana Today.

The four-seat vehicle is equipped with a 15 kilowatt motor and prismatic lithium batteries that consume 5 to 10 units of electricity to be fully charged. There are four operating modes in the car: reverse, normal, eco and fast mode. Reverse mode is used to reverse the car, he said.

In normal mode, the vehicle can drive at a speed of 0-25 km per hour, in eco mode, it moves at a speed of 0-50 km per hour, and in fast mode, the car reaches its maximum speed of 80 km per hour. In each mode, vehicle acceleration is limited to the specified speed limit.

The battery management system is paired with a mobile phone via Bluetooth and provides the complete status of each cell in the battery, such as its life, level of charge and others. In case of errors and faults in the battery, it notifies the user to take corrective action, Rakesh explained.

All of the equipment and parts used in the manufacturing of the car are purchased from manufacturers certified by the Automotive Research Association of India (ARAI) and the International Center for Automotive Technology (ICAT), who test and approve the standards for electric vehicles (EVs), he noted.

Rakesh informed that it took him a month to design and manufacture the vehicle and it is completely handmade. He recently demonstrated the vehicle’s performance in front of Transport Minister Puvvada Ajay Kumar, who appreciated the engineer’s ingenuity.

The engineer now plans to set up a start-up in Khammam to redesign and convert fossil fuel vehicles into electric vehicles as well as manufacture new electric vehicles by employing a few engineering graduates. The minister assured to support his initiative, he added.

In 2019, Rakesh also made an electric bicycle, the battery of which is continuously charged with a dynamo mounted on the vehicle. It has received appreciation from IT Minister KT Rama Rao and others for its innovation.
