Chevrolet Volt

Chevrolet Volt electric car

GM, that ten years from the life of the batteries. Since early 2008 they had launched extensive battery testing and planned to have 10-year battery results in two years. Batteries were placed on the Chevrolet Malibu for further examination of the real world. In April 2008, GM Vice Chairman Bob Lutz said that the first battery-run test mule, now with a lithium-ion battery. Until confirmed for this summer, GM, that a non-turbo, 1.4 liter 4-cylinder engine would be used as a range extender and that the intention is to build it in Flint, Michigan. A photovoltaic solar roof will allow owners trickle charge the battery by leaving the vehicle in the sun, will be offered as optional equipment. Andrew Farah, the car is chief engineer, says that the project remains on track, say, the period until 2010, " taken on this point, there is nothing in the way continue to do what we I said, we do. "

Since the current Society of Automotive Engineers (SAE), the definition of a hybrid vehicle states the vehicle has two or more energy storage " both have to drive power offer, either together or independently, the company has to avoid the use of the term " " hybrid Voltec when describing their designs. Instead, the GM Volt describes as an electric vehicle with a range extending " " with gasoline internal combustion engine (ICE) provided as an aggregate, and therefore in the Extended-Range Electric Vehicle " " name E-REV. But the combination of an internal combustion engine and electric motor in such a configuration is most commonly referred to as a plug-in hybrid-series.

The production design model, first unveiled to the public on 16 September 2008, is very different in design from the original concept car. Appellate necessary aerodynamic changes necessary to extend the original Volt ' s full charge range that uses the new GM Volt Delta II platform, shared by the planned 2010 Chevrolet Cruze and the 2011 Saab 9-3. Although GM does not publicly revealed the production model of aerodynamic drag, they say, it is used less than 0.25 the drag coefficient of the Toyota Prius, a Kammback body.

The Chevrolet Volt is a plug-in hybrid electric vehicle will be produced by the Chevrolet division of General Motors and expected to be introduced as a model 2011th The distribution is expected to begin in November 2010 and also by GM Chapter 11 reorganization of the carmaker the Volt on or before the schedule is kept. The Volt's drive system will be based on new GM Voltec (formerly known as E-Flex) platform, significantly different from BAS earlier GM hybrid and two-mode hybrid system. The first pre-production test car on the full volt design has been built in June 2009 in Warren, Michigan, and by mid-August, 30 volt built and tested under various conditions based.

With fully charged batteries is sufficient electrical energy saved to the Volt up to 40 miles (64 km) power. This distance is the fulfillment of the daily commute for 75% of Americans commute is its ability to average 33 miles (53 km). After 40 miles (64 km), a small 4-cylinder gasoline engine drives a 53 kW (71 hp) generator effectively extending the potential range volts to about 300 miles (483 km) with a single tank of gasoline. The electrical energy from the generator is sent to either the electric motor or the batteries, depending on the state of charge (SOC) of the battery and the required power to the wheels. The distribution is determined by the electronic control unit (ECU) controlling the vehicle.

The Volt concept car has four doors with tailgate, and is equipped with four seats. This is a substantial change in design when compared to General Motors EV1 of the 1990s, who sit only two reduced to weight. The speed limit was increased on the Volt, from the electronically limited 80 miles per hour (130 km/h) to 100 miles per hour (160 km/h). The battery size was therefore reduced by approximately 300 L volume in the EV1, to only 100 in the LV.

The electrical power for the vehicle from the following sources of their on-board lithium - ion batteries that are recharged by an electrical outlet and/or the gasoline engine. The Volt's 16 kWh (8.8 kWh usable) lithium-ion battery can be charged by plugging it into the car in a residential area, 120-240V AC power outlet using the dedicated SAE J1772-compliant charger will be charged. No external charger is required. Unlike most current commercial electric hybrids, is the real drive of the Volt achieved solely by the electric motor.

To spur battery research, GM selected two companies to provide advanced lithium-ion batteries: Compact Power (CPI), the manganese-based cells of its parent company, LG Chemical, and Continental Automotive Systems, which uses Nanophosphate made based columnar cells made by A123Systems used. But on 9 August 2007, GM established a close relationship with A123Systems so that the two companies co-develop a specific volt battery cell could. This cell was subsequently presented at the EVS23 industry convention in Anaheim, California. She works with CPI at a rapid pace, and the end of 2007 CPI delivered two fully functional prototypes to test batteries to GM facilities. On 31 Delivered in January 2008, A123 and Continental its first prototype test of GM's European facilities. GM announced on 12 January 2009 that it would use LG Chem batteries for the production model.
