India's First Electric Car Launched

NEW DELHI, June 25 (Bernama) -- After 13 years of research and development, India's first electric car Reva was launched in the capital Delhi Wednesday morning.

The Reva is a small 3-door hatchback measuring 2.6 meters long, 1.3 meters wide and 1.5 meters high. It weighs 745 kilograms.

The car can accommodate two adults in the front and two children in the rear.

New Delhi Chief Minister Sheild Dik# said the government is committed to taking steps to improve the city's environment.

"It is a green day for Delhi. I have been using the car myself for short distances and I like it a lot," the Press Trust of India (PTI) quoted Sheila as saying at the ceremony.

She said Delhi's government was committed to taking steps to improve the city's environment.

"I appeal to all those who have several cars to at least buy one Reva," she said.

To popularize the battery-operated car, Delhi's government announced a 15 percent subsidy on its base price, 12.5 percent exemption of value-added tax (VAT), and a refund of road tax and registration charges.

The subsidy and exemptions would bring down price of Reva's base model to US$7,100.

It is manufactured by the Reva Electric Car Co, in Bangalore, India.

Asked about their target, Reva Electric Car Co's president Girish M. Rakhe said: "We will be very happy if we sell 3,000 cars in the capital in our first year."

The battery is the weakest part of an electric car. Now technology plays buddy and an active role to make your battery last longer while your car swallows up the miles.

ONE of the most frequently asked questions that Reva India's first and only electric car provokes is, "But what about the battery? What happens if the charge runs out while I am on the road?"

"The battery is the weakest part of an electric car," says Paul Schwiezer, who has worked with electric cars worldwide and is the technical head of Reva Electric Car Company. Customers of electric vehicles in general have been dissatisfied with operating costs, specially that which arise from battery replacement, says the company.

While a battery lifetime of 2-4 years is quoted, very often replacement needs arise after 12 to 18 months. The biggest reason is over-discharging and over charging of the battery, says Schweizer. Too much discharge can cause damage to the car.

One of Reva's first concerns was to put in place an information management system called the Energy Management System to measure energy discharge, manage battery range, save energy wherever possible and keep a history of the usage pattern. Information from the EMS is used to offer better service.

For instance, when the battery is low, a signal is sent out and the car runs on a mode that uses lesser energy to conserve it for a longer time. In a regular car, the fuel indicator is a simple device telling you that you are running out of fuel. But in Reva, a chemophysical device with sophisticated algorithms decides the phase of the battery and gives indications to the EMS which activates flashing red and green lights on the dashboard.

Reva's EMS also offers diagnostics, specially the history of the battery. Unlike the EMS in a regular car which only records abnormalities, Reva's system notes every change in the life-cycle from the number of kilometres, the maximum speed, energy consumed and so on.

The data collected provides an important tool for the company itself to discover usage patterns and the requirements for improvement.

The company has extended the use of the EMS to service station hands. Each service station has palmtops which can download data from the EMS. The data is interpreted to offer quick diagnosis, making servicing easy.

Reva has already got an order for the system from another electric vehicle-maker, says Schweizer. As the system contains a full history of what happens to the engine, there has even been an enquiry from a global manufacturer of batteries to use the EMS to get a feedback on the performance of the battery, he says.



rasa2nya m'sia ada tak nanti keta elektrik nih       REVA dah ada... VIVA tak leh pakai  marah lak..perodua nanti...
