Mixing can be defined as a device, instrument, or anything with two or more different things.Therefore, hybrid vehicles can be defined as vehicles with two or more different vehicle properties.The most commonly used terms for these vehicles are hybrid electric vehicles or hybrid vehicles.These vehicles have an internal combustion engine and one or more electric motors.Hybrid vehicles are environment friendly compared to other fuel-emitting vehicles.The low emissions of this fuel to the environment are achieved through the small size of the engine.The smaller the size of the engine, the smaller the interference to the environment.The Environmental Protection Agency or the Environmental Protection Agency recommends that the carbon dioxide emitted by ordinary passenger cars not exceed 5.5 metric tons, which makes hybrid cars more beneficial to EPA because the amount of carbon dioxide emitted by these vehicles is less than or equal to this set limit.Taking the most popular vehicles as an example, we can see how these hybrid cars are favored by EPA.Toyota Prius, Honda Civic and Insight emit 3.5, 4.1 and 3.5 tons of carbon dioxide, below the set level of carbon dioxide emissions to the environment.These vehicles are also able to reduce emissions or other pollutants by 90%.The most common battery types in hybrid cars are;Lithium-It turns out that both types of batteries are eco-friendly.Lithium-Compared with nickel metal hydrogen batteries, ion batteries are considered less harmful.Hydrogen-nickel batteries are less toxic than lead-acid or nickel-cadmium batteries.Lithium-Compared to most batteries, ion batteries are much smaller in size, much lighter in weight and more efficient in charging.These batteries have better performance than nickel metal batteries, producing three times the voltage of nickel metal batteries.These batteries are also able to store more energy than nickel metal batteries.They are also able to save up to 30% of fuel and the environment by reducing the level of carbon dioxide emissions in the environment.The operating cost of a hybrid car is reduced because it operates partly by electricity, partly by battery, and partly by fuel.These vehicles are also re-Use the energy wasted when braking, save more energy in the battery and reduce fuel costs.Use of lithium-Ion batteries in hybrid cars will also benefit users in saving costs, as this battery is able to store more energy, better performance and longer life compared to other types of batteries.The price of hybrid cars is high compared to ordinary cars.This is because some expensive materials are used when making these cars.Rare earth elements are an element used in hybrid cars and are very rare in nature.For the manufacture of motors and batteries.Another rare element used in these vehicles is nd.It is also used for electric motors.Most of these rare elements are found in China. if they are not found elsewhere in the world in the near future, it is difficult for these companies to create such costs.Efficient and eco-friendly vehicles.The company not only produces hybrid cars, but also other vehicles such as hybrid cars, railway trains, cranes, ships and even aircraft.All these means of transportation are costs.Efficient environmental protection.When it comes to hybrid cars, that doesn't mean that these engines are just based on the properties of fuel and electricity, but there are other types of engines that are being built for these vehicles.Petro-Petro-Electric-Knowing the benefits of these vehicles, the trend is still not very big for them.At present, few individuals and companies like hybrid cars, but it is expected that this trend will rise in the near future, when their costs will be reduced and efficiency will increase
