What are the power sources of new energy vehicles?
1 Answers
New energy vehicles mainly derive their power from four aspects: pure electric, fuel cell, hydrogen energy, and gas. Below are the detailed introductions: Pure Electric: New energy vehicles primarily rely on electric power for propulsion. Most vehicles are directly driven by electric motors. Some vehicles have motors installed in the engine compartment, while others use the wheels themselves as the rotors for four motors. The main challenge lies in energy storage technology. They do not emit harmful gases that pollute the atmosphere. Even when the electricity consumption is converted into emissions from power plants, pollutants other than sulfur and particulate matter are significantly reduced. Since most power plants are located far from densely populated cities, the harm to humans is minimized, and the stationary nature of power plants makes it easier to eliminate concentrated harmful emissions, with relevant technologies already in place. Fuel Cell: Fuel cell vehicles refer to those that use hydrogen, methanol, etc., as fuels to generate electric current through chemical reactions and rely on electric motors for propulsion. The energy in the battery is not obtained through combustion but is directly converted into electricity or electrical energy through the chemical interaction of hydrogen and oxygen. The chemical reaction process of fuel cells does not produce harmful byproducts, making fuel cell vehicles pollution-free. The energy conversion efficiency of fuel cells is 2 to 3 times higher than that of internal combustion engines. Therefore, fuel cell vehicles are considered ideal in terms of energy utilization and environmental protection. Hydrogen Energy: Hydrogen energy new energy vehicles are a mode of transportation that truly achieves zero emissions, emitting only pure water. They boast the advantages of no pollution, zero emissions, and abundant reserves. Thus, hydrogen-powered vehicles are the best alternative to traditional vehicles. Compared to traditional power vehicles, hydrogen-powered vehicles cost at least 20% more. Gas: Gas-powered vehicles refer to those that use compressed natural gas, liquefied petroleum gas, and liquefied natural gas as fuels. Governments worldwide are actively seeking solutions to this issue and have begun adjusting the fuel structure of vehicles. Due to their excellent emission performance, adjustable fuel structure, low operating costs, mature technology, and safety and reliability, gas-powered vehicles are considered the most ideal alternative fuel in the world.
