5 minutes to know EV, HEV, PHEV and FECV

In recent years, new energy vehicles have been on the fast track of rapid development. All major vehicles in the world are deploying new energy vehicles, and some EVs have achieved good sales. As the ban on sales of ICE engines approaches, electric vehicles will become a major trend. There are many types of new energy vehicles, such as EV, HEV, PHEV, FCEV. Which new energy models do these abbreviations represent? What are the advantages of different models?

1.EV: Electric vehicle

Pure electric vehicles are vehicles driven purely by electricity.
The power system is divided into two parts: the electric energy storage system (that is, the battery pack), and the electric motor that provides the driving force. Today, the technical complexity of pure electric vehicles in battery materials, battery management, electric motors, and on-board equipment is far beyond your imagination, which is why the prices of pure electric vehicles are often not cheap. It is because the current battery life of pure electric vehicles is not strong. The current drawbacks of pure electric vehicles are also obvious. Many models have a cruising range of only one or two hundred kilometers, and the charging time is relatively long, so they are only suitable for urban travel, not suitable for long-distance journeys.

Drive mode: Only use electric motor to drive the vehicle.
Features: It only relies on electric motors to drive the vehicle, without a gasoline engine, so it is quieter when driving.

2.HEV: Hybrid Electric Vehicle

The simplest understanding of the gasoline-electric hybrid vehicle is to add a set of electric drive equipment on the basis of the original gasoline vehicle, “double engine”.
Since the electric motor has the inherent advantage of the maximum torque, the electric motor will assist the engine to work when the vehicle starts, climbs, and accelerates when the vehicle needs high torque output, thereby helping the vehicle reduce energy consumption and achieve energy saving the goal of. However, the battery of this type of car is relatively small, so the vehicle’s engine and the recovered energy generated during braking can fill the battery, and then the energy in the battery can drive the motor in the car to help the vehicle travel, so this type of car does not have Set up an external charging port.
Drive mode: Rely on electric motor and internal combustion engine to work.
Features: The electric motor and the internal combustion engine assist each other, with low fuel consumption, low emission pollution, and no mileage anxiety.

3.Plug-in Hybrid Vehicle

Like HEV, PHEV models will have traditional fuel engines and electric motors. But the difference between PHEV and HEV is that the battery of PHEV will be larger, and can support long-term pure electric driving, at the same time there will be an additional set of charging mechanism. Therefore, PHEV can be driven as a pure electric vehicle or as a traditional gasoline vehicle. However, it should be noted that PHEV models have a heavier vehicle weight due to the existence of large-capacity batteries and motors. When the vehicle battery energy is exhausted, if the vehicle is not charged through the charging pile, it will only be charged by the engine and the kinetic energy recovery device. Fuel consumption. In addition, PHEV models are limited by battery capacity and vehicle structure, so the mileage in pure electric mode will not be very long.
Drive mode: use electric motor and internal combustion engine to drive the vehicle.
Features: Compared with traditional internal combustion engine vehicles, it is more fuel-efficient and more free than pure electric vehicles.

4.Fuel Cell Electric Vehicle

A fuel cell vehicle is a vehicle that uses electricity generated by an on-board fuel cell device as power. The fuel used in the on-board fuel cell device is high-purity hydrogen or high-hydrogen reformed gas obtained by reforming hydrogen-containing fuel. Compared with pure electric vehicles, the power for fuel cell vehicles comes from the on-board fuel cell device. Therefore, The key to fuel cell vehicles is fuel cells. The working principle of the fuel cell vehicle is that the hydrogen used as fuel in the fuel cell mounted on the vehicle undergoes an oxidation-reduction chemical reaction with oxygen in the atmosphere to generate electrical energy to drive the electric motor to work, and the electric motor drives the mechanical transmission structure in the vehicle. Drive the front axle (or rear axle) and other walking mechanical structures of the vehicle to work, thereby driving the electric vehicle forward.
Drive mode: Only the electric motor is used to drive the vehicle, and hydrogen is used as fuel to produce a chemical reaction with oxygen, thereby using the generated electrical energy as a power source.
Features: There are endless sources of hydrogen and oxygen, no pollution, and it can be called a “true pollution-free vehicle.”
