Chevrolet Volt – The General Motor’s Hybrid Car

You are here: Home // Head Lines, Transportation // Chevrolet Volt – The General Motor’s Hybrid Car

The Chevrolet Volt is a plug-in Hybrid vehicle to be produced and launched in November 2010 as a 2011 model. The Volt’s propulsion system will be based on GM’s new Voltec (formerly known as E-Flex) electric automobile platform, which differs significantly from GM’s earlier BAS Hybrid and Two-Mode Hybrid systems.

Engine and Power Supply

It has an Engine Power of 111 kW (149 hp) electric motor and 1.4 L 4-cylinder for powering 53 kW (71 hp) generator. For up to the first 64 km (40miles) the Volt will be powered by electricity, which is charged in lithium-ion batteries that charged from an electrical power outlet. After 64 km, a small 4-cylinder gasoline internal combustion engine creates electricity on-board using a 53 kW (71 hp) generator to extend the Volt’s range to more than 300 miles (483 km). The electrical power from the generator is sent to either the electric motor or the batteries, depending on the state of charge (SOC) of the battery pack and the power demanded at the wheels.

The Model

The Chevrolet Volt has four doors with a rear lift gate and can be seated for four passengers. In addition, the top speed has also been increased from the electronically 134 km/h to 160 km/h. The battery pack size has also been reduced from 300L to 100L. The design model first revealed to the public on September 16, 2008. The lithium-ion battery technology in which the cathode contains the lithium has a large impact in determining the success of the car.

Efficient Fuel Consuming

If the batteries are fully charged, without any other fuel supplies, the Volt can travel less than 64 km trips using only the stored electricity in lithium-ion batteries. Once the Volt’s battery has discharged to the estimated 30% lower State of Charge (SoC) limit, the engine starts and supplies power to the electric motor to continue driving the car and maintain the battery charge at 30%.

The Smart Phone Application For The Chevy Volt

General Motors has unveiled an application, which has successfully developed by the OnStar for Chevrolet Volt drivers that will let them remotely control the whole car in their Blackberry, iPhone or Motorola Droid in the International Consumer Electronics Show in Las Vegas on 05th of January 2010.

Drivers can communicate with their Volt using the OnStar’s Mobile Application with the real-time data connection to perform number of tasks. The OnStar application has offered a wide range of interaction and control, which has never offered on any electric vehicle before. The features including:

  • Display charge status
  • Schedule time for charge or notify to charge
  • Display battery charge level in percentage
  • Notify via text messages to drivers to plug in their vehicle when the battery level is low
  • Status reports
  • Warming up or cooling the vehicle before getting in
  • Showing miles per gallon, EV miles and miles driven for last trip and lifetime

The president of the OnStar Walt Dorfstatter has stated  that “The Chevrolet Volt ushers in a new era of automotive technology and calls for a new level of connectivity and control, Nearly 6 million vehicles on the road today use OnStar to stay connected, and our new Smartphone app will make that even easier for Volt drivers.”

OnStar servers are the intermediary between the OnStar application and the Volt. The application has the communication facility with the OnStar servers. Because of the OnStar’s real-time data connection, it helps drivers maximize the environmental benefits owning a Volt. Using the power from the grid, the driver can remotely start the Volt to pre-condition the interior temperature. It saves the battery charge for long driving.

Volt drivers can also view and manage vehicle systems and commands from the vehicle, the Internet or through a monthly OnStar Vehicle Diagnostic e-mail. Traditional OnStar features such as door lock, unlock and remote horn and lights-typically accessible only through a call to an OnStar center-will be available via the application.

Currently the application works on the Apple iPhone, Motorola Droid and Blackberry Storm, and General Motors says it also will be available on a mobile browser for other Smartphones. The demo application can be downloaded from iTunes store for Apple iPhone and for Motorola Droid and Blackberry Storm the application available at Initial sales of the Chevy Volt, scheduled for production in late 2010 and the price have estimated to $40,000.
