Electric car is an alternate fuel automobile that uses electricity instead of petrol or diesel. These automobiles have electric motors and controllers used for propulsion. These vehicles do not use the traditional or the common methods of propulsion like ICE (internal combustion engine). These cars are energy efficient and are capable of reducing city pollution because of the zero tail pipe emission.
On-board battery packs are the main power supply to the car. The functioning of the cars greatly depends on the quality of the battery used in the car. The poor battery may result into long hours of recharging and poor speed with poor acceleration. These cars are not practically suitable for long journey but can be a good transportation vehicle for everyday use and can be recharged overnight.
The new electric version of i10 is termed as zero-emission urban commuter consisting a 16kWh battery and a 49kWh electrical motor. The batteries incorporate Li-Poly batteries that are capable to produce equaling power as compared to NiMH batteries. The advantage of Li-Poly batteries over the NiMH batteries is that, Li-poly weighs much lesser than that of NiMH. Recharging the batteries from 220V outlet will take up to 5 hours whereas recharging from a 413V outlet will take only 15 minutes to complete 85% of the charge. You can drive up to 160 km with the top speed of 130 kmph.
Chevrolet Beat is the latest launch of General Motors. General displayed 11 concept vehicles at Auto Expo.

Chevrolet Volt is an electric car that is capable of creating its own electricity. Once it is charged completely, it is ready to run on electric charge for up to a range of 40 miles i.e. 64.374 km. After that, Volt keeps going, even if you can’t plug it in. Volt uses a range-extending gas generator that produces enough energy to power it for hundreds of miles on a single tank of gas.
The second hybrid car launched at Auto Expo that will be available in Indian market is Toyota Prius. The Prius was launched in 2009 in the international market. The design is more aerodynamic if compared to the previous version of it. The coefficient of drag reduced to 0.25 Cd, The 1.8-liter petrol engine generates about 100PS and with the added power of the electric motor, combined power is 136PS. The Prius engine, with an electric water pump, is the first production engine that requires no accessory belts improving fuel economy.
The REVA Electric Car company is the leader in the electric car producer and is ready to launch two new and improved electric car version namely REVA NXR and REVA NXG. Unlike the previous electric car REVA, which was two seater , small and compact car, the NXR is a three door, four seater and much spacious model. It can accelerate to a maximum speed of 105 km/h with a range of 160 kilometers on a single charge of its lithium-ion battery pack. The new models are coming up with improved charging that might result in 15-minute faster recharge as compared to the older version. However, it might take up to 8 hours to completely recharge the battery packs from a regular household outlet.
