We all know that electric vehicles are also a type of new energy vehicle, but we are not very clear about the technical principles of electric vehicles and the technical principles of electric vehicles. Let ’s take a look with Xiaobian!
Electric vehicle charging equipment
The drivers energy of the motor is derived from the vehicles charging battery or other energy storage devices.
Most vehicles are directly driven by motor. Some vehicles put the motor in the engine compartment, and some also use the wheels as a rotor of the four electrical motors. The difficulty is the power storage technology.
The driving power of the motor itself does not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted into the emissions of the power plant, except sulfur and particles, other pollutants are significantly reduced.
Electric vehicles can also make full use of the surplus electricity charging when the low -cost downturn at night, so that the power generation equipment can be fully utilized day and night, which greatly improves its economic benefits.It is these advantages that make the research and application of electric vehicles a "hot spot" in the automotive industry.
Six -segment charging similar to the ICM staircase of the mobile phone charging, has a good sulfurization effect, can be activated first, and then fast charging for maintenance. It has a regular, full alarm, computer fast charging, password control, self -recognition voltage voltage, Multiple protection, four -way output and other functions, supporting universal output interfaces, can quickly charge all electric vehicles.Public places such as shopping malls, supermarkets, hospitals, parking lots, entrances at the community, and roadside sellers.
The construction model of the automotive charging network. During the promotion of the charging facility, the problem that needs to be broken is the problem of the charging service network.Relying on the existing parking lot facilities, the power department can build a micro grid, distributed, comprehensive charge, and replaceable full -function charging stations according to local conditions to avoid two shortcomings in the charging mode: one is long charging time, twoThe parking environment is limited.
Technical principle electric vehicle
Motor and control system
Pure electric vehicles replace fuel engines with electric motors, driven by motor without an automatic transmission.Compared with automatic transmission, the motor structure is simple, mature, and reliable.
Traditional internal combustion motors can limit the speed when the efficient torque generates torque to a narrow range. This is why traditional internal combustion engines need huge and complex transmission mechanisms; and electric motors can produce torque efficient torque within a relatively wide range of speed range.There is no need to switch gear device during the driving of pure electric vehicles. It is easy to control and low noise.
Compared with hybrid vehicles, pure electric vehicles use a single electrical energy, and the electrical control system has greatly reduced the internal mechanical transmission system of the vehicle, the structure is more simplified, and the energy loss and noise caused by the friction of mechanical parts will be reduced.weight.
The motor -driven control system is the main execution structure in the driving of new energy vehicles. The driving motor and its control system are one of the core components (batteries, motors, and electronic controls) of new energy vehicles.Indicators, it is an important part of electric vehicles.The three categories of fuel cell vehicles in electric vehicles, FCV, hybrid vehicle HEV, and pure electric vehicle EV must be used to drive wheels with electric motors. Choosing appropriate electric motors is an important factor in increasing the cost performance of various electric vehicles.At the same time, it is extremely important to meet the performance requirements of the vehicle during driving and have the characteristics of sturdy durability, low cost, and high efficiency.
Electric vehicle system structure
Electric vehicles refer to vehicles that use vehicle power as the power and use motor to drive the wheels, which meet the requirements of road traffic and safety regulations.It uses the electricity stored in the battery to launch.Sometimes 12 or 24 batteries are used when driving cars, sometimes more.
Provide electrical energy for the driver motor of electric vehicles,
Driver motor
The role of the driving motor is to convert the power of the power to mechanical energy, and drive the wheels and working devices directly through the transmission device or directly drive the wheel and working device.However, due to the existence of the directional spark, small power, low efficiency, and large maintenance workload due to the development of the directional spark; with the development of motor control technology, it is bound to gradually be gradually being used by DC brushless motor (BLDCM), switching magnetic resistance motor (SRM), and AC asynchronousThe electric motor is replaced by an outer shell -type axial magnetic field DC motor.
The motor speed control control device is set for the transmission and direction transformation of electric vehicles. Its role is to control the voltage current of the motor to complete the control torque and rotation direction of the motor.
The role of an electric vehicle transmission is to pass the motors torque to the driver shaft of the car. When the electric wheel drive is used, most of the parts of the transmission device can often be ignored.Because the motor can start with a load, there is no need for a clutch of traditional internal combustion engines on electric vehicles.
Driving device
The role of the driving device is to turn the driving moment of the motor through the wheels into a force on the ground and drive the wheels to walk.It is the same as the composition of other cars, consisting of wheels, tires and suspension.
Steering device
The steering device is set up to achieve the turning of the car, consisting of steering machines, steering wheels, steering mechanisms, and steering wheels.The control of the action on the steering wheel, through the steering machine and the steering mechanism to make the steering wheel deflection a certain angle to achieve the turning of the car.
Braking device
Like other cars, electric vehicles are set up for vehicles to decelerate or park. They are usually composed of brakes and their controllers.exist
On electric vehicles, there are generally electromagnetic braking devices. It can use the control circuit of the driving motor to achieve the power generation of the motor, so that the energy during the deceleration brake is converted into the current of the battery charging, so as to obtain regeneration.
working equipment
The working device is specially set up by industrial electric vehicles to complete the operating requirements, such as the rising device, door frame, and fork of electric forklifts.The rising of the fork and the tilt of the door frame are usually completed by the motor -driven hydraulic system.
