Electric vehicle (BEV) refers to a vehicle that is driven by a vehicle power source and drives the wheels with a motor to meet the requirements of road traffic and safety regulations. As the impact on the environment is relatively small compared to traditional cars, its prospects are widely optimistic, but the current technology is not mature.here
Several types of electric cars:
1.The fuel cell
A car that uses a fuel cell as a power source. The chemical reaction process of a fuel cell does not produce harmful products, so
Fuel cell vehicles are pollution-free vehicles. The energy conversion efficiency of fuel cells is 2 to 3 times higher than that of internal combustion engines. Therefore, fuel cell vehicles are an ideal vehicle for energy utilization and environmental protection.
A single fuel cell must be combined into a fuel cell stack to obtain the necessary power to meet the requirements of the vehicle.
A pure electric vehicle is driven by an electric motor.
Pure electric vehicles, relative to fuel vehicles, the main difference (different) lies in four major components, drive motors, speed controllers, power batteries, and car chargers. Relative to the gas station, it consists of a public ultra-fast charging station. The difference in quality of pure electric vehicles depends on the four components, and the value depends on the quality of the four components. The use of pure electric vehicles is also directly related to the selection and configuration of the four major components.
The speed of a pure electric vehicle is fast and slow, and the starting speed depends on the power and performance of the driving motor. The length of its continuous mileage depends on the size of the vehicle’s power battery. The weight of the vehicle’s power battery depends on which power battery is used, such as lead acid and zinc. Carbon, lithium batteries, etc., their volume, specific gravity, specific power, specific energy, cycle life are all different. This depends on the manufacturer’s positioning and use of the vehicle grade as well as market definition and market segmentation.
Refers to a car that can at least derive power from the energy stored in two types of vehicles:
A consumable fuel or rechargeable energy/energy storage device.
According to the structure of the power system, it can be divided into the following three categories:
Series Hybrid Electric Vehicle (SHEV): The driving force of a vehicle is only derived from a hybrid (electric) vehicle of an electric motor. The structural feature is that the engine drives the generator to generate electricity, and the electric energy is sent to the motor through the motor controller, and the motor drives the car to travel. In addition, the power battery can also provide power to the motor alone to drive the car.6 inch mini electric scooter portable foldable for adult
Parallel hybrid electric vehicle (PHEV): A hybrid (electric) vehicle in which the driving force of the vehicle is supplied simultaneously or separately by the electric motor and the engine. The structural feature is that the parallel drive system can use the engine or the electric motor alone as the power source, or can use the electric motor and the engine as the power source to drive the car at the same time.
Hybrid Electric Vehicle (CHEV): A hybrid (electric) vehicle with both series and parallel drive. The structural feature is that it can work in series mixing mode or in parallel mixing mode, taking into account the characteristics of series and parallel.
