I. Definition of New Energy Vehicles

New Energy Vehicles (NEVs) refer to vehicles that use unconventional automotive fuels as their power source, combined with advanced power control and drive technologies. These vehicles embody advanced technical principles, new technologies, and new structures. Currently, the market and research institutions are primarily focused on pure electric vehicles and hybrid electric vehicles. Therefore, NEVs are often considered synonymous with electric vehicles.

II. History of Electric Vehicles

Electric vehicles are not a 20th-century invention. As early as 1894, Britain's Thomas Parker successfully developed the world's first mass-produced four-wheel electric vehicle. With a history spanning over a century, electric vehicles were gradually phased out in competition with fuel-powered vehicles due to short driving ranges, limited battery life, and inconvenient charging.

III. The Resurgence of New Energy Vehicles

By the late 20th century, the sharp increase in private car ownership led to escalating issues like the depletion of oil resources and atmospheric pollution. This prompted a renewed focus on electric vehicles. The once-abandoned electric vehicle technology regained attention from governments and major automobile manufacturers worldwide.

IV. The Four Main Types of New Energy Vehicles

NEVs are mainly categorized into the following four types:

1. Battery Electric Vehicles (BEVs)

BEVs rely solely on electric power, with their power systems composed of batteries and electric motors. Completely independent of internal combustion engines, they produce zero emissions during operation, making them one of the most environmentally friendly vehicle types.

2. Hybrid Electric Vehicles (HEVs)

HEVs are equipped with both internal combustion engines and electric power systems. They use electric motors for propulsion when driving at low speeds, where internal combustion engines are less efficient. The electrical energy is not obtained from external charging but is generated through the recovery of kinetic energy during engine operation, downhill driving, and braking.

3. Plug-in Hybrid Electric Vehicles (PHEVs)

The main difference between PHEVs and HEVs is that PHEVs can be charged from external power sources and generally have larger battery capacities. They can rely solely on batteries and electric motors to drive longer distances, achieving higher fuel economy.

4. Fuel Cell Electric Vehicles (FCEVs)

FCEVs convert chemical energy into electrical energy, which then powers electric motors to drive the vehicle. Primarily using hydrogen fuel cells, these vehicles can be quickly refueled at hydrogen stations, similar to traditional fuel vehicles. With a well-established hydrogen refueling network, range anxiety is virtually eliminated.
