What does new energy EV mean?

EV stands for Electric Vehicle, which literally translates to electric car. Essentially, all vehicle models powered by electric motors can be referred to as EVs. Below is a relevant introduction to new energy vehicle types: 1. HEV: Hybrid Electric Vehicle, abbreviated as HEV or HV, is a hybrid vehicle that relies on both fuel and batteries to provide energy. Hybrid vehicles add batteries and electric motors to conventional fuel-powered cars. The battery capacity is usually relatively small, but it does not require external charging as it automatically recharges by recovering energy during driving. Due to the small battery capacity, the main role of the electric motor is to assist the fuel engine during driving, achieving fuel savings and improving acceleration and uphill performance. The vehicle only enters pure electric mode when driving at low speeds. Currently, HEVs are the most commonly seen new energy vehicle models on the market, and governments worldwide also provide various subsidies for HEV models. 2. PHEV: PHEV stands for Plug-in Hybrid Electric Vehicle. The biggest difference between PHEV and HEV is that PHEV requires external charging via a socket or charging station. PHEVs have much larger battery capacities than HEVs, allowing for longer distances in pure electric mode. The electric motor and fuel engine complement each other; for example, fuel energy is used during high-speed driving, while electricity is used for starting or low-speed driving to improve efficiency. PHEVs also offer more mode options, such as using pure electric mode in urban areas and switching to fuel mode when the battery is depleted, which can save more fuel. Another advantage of PHEVs is that there is no worry about being unable to drive when the battery is depleted (a problem with pure electric vehicles), as the vehicle can still operate normally using fuel when the battery is empty.
