What Energy Sources Do New Energy Vehicles Use?
3 Answers
New energy vehicles primarily utilize fuel cells, hybrid power, and hydrogen energy. New energy vehicles refer to vehicles powered by energy sources other than gasoline or diesel engines, including solar energy, among others. New energy vehicles encompass four main types: Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEV, including solar-powered vehicles), Fuel Cell Electric Vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). Battery Electric Vehicles (BEV) are vehicles that rely solely on a single battery as the energy storage power source. They use the battery to store energy, which is then supplied to the electric motor to drive the vehicle. Hybrid Electric Vehicles (HEV) are vehicles with a drive system composed of two or more individual drive systems that can operate simultaneously. The driving power is provided by one or more of these systems depending on the actual driving conditions. HEVs come in various forms due to differences in components, layout, and control strategies. Fuel Cell Electric Vehicles (FCEV) use electricity generated through electrochemical reactions between hydrogen and oxygen in the air, catalyzed in fuel cells, as their primary power source. Essentially, FCEVs are a type of BEV, differing mainly in the working principle of the power battery. Hydrogen engine vehicles are powered by hydrogen engines. Unlike conventional engines that use diesel or gasoline, hydrogen engines use gaseous hydrogen as fuel. These vehicles achieve true zero emissions, releasing only pure water, and offer advantages such as no pollution, zero emissions, and abundant reserves.
I usually enjoy delving into automotive knowledge. The primary energy source for new energy vehicles is electricity, which comes from onboard batteries. This electricity can be charged from various sources, such as household sockets or public charging stations connected to the grid. If the electricity comes from renewable sources like solar or wind power, it’s even more environmentally friendly. Common types include pure electric vehicles (fully powered by electricity) and plug-in hybrid vehicles (using electricity and a bit of gasoline). A key advantage is that electric motors replace traditional fuel, reducing exhaust emissions. However, if the charging station’s grid relies on coal-fired power, the environmental benefits may be diminished. In daily use, it’s important to pay attention to battery range and charging time, as these directly impact driving convenience.
I find driving new energy vehicles quite convenient. The energy source is electricity, stored in a large battery located at the bottom of the car. Every time I return from driving, I just find a charging station to plug in, and it's fully charged in a few hours, as simple as charging a phone. The electricity may come from home power sources or roadside charging stations, and using solar panels can make it even more cost-effective and environmentally friendly. The core is that the electric motor replaces the engine, eliminating the need for refueling and producing no exhaust emissions. Occasionally, when going on long trips, range anxiety may arise, but it can be managed by planning charging stops in advance. The battery lifespan is generally around 8-10 years, with relatively low maintenance, making the overall usage cost significantly lower than that of gasoline-powered cars.
