Recently, many car manufacturing companies have produced and supplied electric cars in the market. It is true that having an electric car is still not easy. Customers do not have many choices to buy, and the charging infrastructure is not enough. In addition, although the government gives benefits to electric car drivers, the prices of the cars are relatively higher than conventional cars. However, many companies are making the generation of electric cars possible. Currently, plug-in hybrid cars and pure electric cars are produced in the market.
Plug-in hybrid cars share the characteristics of both conventional internal combustion engine cars and electric cars. Different from hybrid cars, drivers can charge their cars with not only gasoline but also electricity. One example is BMW i8.
The i8 uses a three cylinder turbocharged petrol engine, with a 1.5liter capacity, in conjunction with an electric motor. The high-voltage battery can be recharged from a conventional household power socket or at a public charging station. The battery can also be recharged via the electric motor on the overrun. The plug-in hybrid cars are between conventional gasoline cars and pure electric cars.
Pure electric cars, which is also called EVs, are only charged with electricity. They have electric motors, using rechargeable batteries instead of internal combustion engines. One of the significant features is that EVs are emission-free. With the current technology, most EVs cannot be driven long distance once it is charged. Therefore, they are mostly used in cities. I think that in mega cities, where air pollution is serious, EVs will help improve the environment. The BMW i3, Tesla Model X and S, and Volkswagen E-Golf are the examples.
