The basic structure of electric cars

The composition of electric vehicles, including electric drives and control systems, power transmission and other mechanical drive system, complete installation tasks. Power driver and control system is the core of electric vehicles as well as internal combustion engines of motor vehicles from the largest difference. Power driver and control system by the drive motor, power supply and motor speed control device and so on. Electric vehicles equipped with the basic and the other the same internal combustion engine vehicle.

2.1. Of electric vehicles, electric power cars

Power for electric vehicles, electric cars provided by the drive motor power, motor power of the mechanical energy into electrical energy through the direct drive gear or wheel and the work device. At present, electric vehicles on the most widely used lead-acid laptop battery power source is, but with the development of electric vehicle technology, and many are developing new type of battery. These power supply (batteries) are mainly sodium sulfur batteries, nickel-chromium batteries, lithium batteries, fuel cells, flywheel batteries, etc. Application of the new power supply for the development of electric vehicles has opened up broad prospects.

2.2. Of electric vehicles, electric cars drive motor

The role of motor-driven power supply is the mechanical energy into electrical energy through the direct drive gear or wheel and the work device. At present, electric vehicles, electric cars on the widely used series-excited DC motor, this motor has a “soft” mechanical properties, and the car is very consistent with the traffic characteristics. However, due to the existence of DC motor commutation spark power than smaller, less efficient, maintenance workload, with the electric motor control technology and technological development, it is bound to gradually brushless DC motor (BCDM), Switched Reluctance Motor (SRM) and replaced by the exchange of asynchronous motor.

2.3. Of electric vehicles, electric car motor speed control device

Motor speed control device for electric vehicles, such as variable speed and direction of change set, its role is to control the motor voltage or current, the completion of the drive motor torque and the control of rotation direction.

Early electric cars, electric cars, electric cars, electric cars using DC motor speed control or change the electrical series resistance of the magnetic field coil turns to achieve. Because there is a level of speed and will produce additional electrical energy consumption or use of the structure of the complex, it is now seldom used. At present, the application of electric vehicles is a wider range of speed control thyristor chopper through the uniform change of the terminal voltage motor control motor current, to realize stepless speed regulation motor. In the electronic power of the continuous development of technology, it also gradually by other power transistor (into the GTO, MOSFET, BTR and IGBT, inspiron e1505 battery etc.) to replace the chopper speed control devices. From technology development, along with the application of the new drive motor, electric vehicles into the speed control of DC Inverter technology, will become the inevitable trend.

Electric vehicles, electric cars in the drive to transform rotary motor control, DC motor armature to rely on contacts or change the current direction of the magnetic field, the spin motor to achieve the transformation, which makes circuit complexity, reliability, lower. When the exchange of asynchronous motor drive, the motor can turn to transform the magnetic field changes the phase sequence of three-phase current to enable simplified control circuitry. In addition, the use of AC motor and VVVF control technology, electric vehicles, electric cars the braking energy recovery control more convenient and more simple control circuit.

2.4. Of electric vehicles, electric cars gear

Electric vehicles, electric cars is the role of transmission of drive torque to the motor vehicle to the driveshaft, when the use of electric-wheel-drive, the transmission components are often the most can be ignored. Because the motor can be activated with the load, so no need for electric vehicles on the clutch of traditional internal combustion engine vehicle. Because of the rotary drive motor circuit can be controlled to achieve the transformation, so no internal combustion engine for electric vehicles in the auto reverse transmission. When motor stepless speed control, electric vehicles can be ignored traditional transmission vehicles. In the use of electric-wheel-drive, the electric vehicles can also be omitted from the traditional internal combustion engine vehicle of the differential transmission system. I also charge my inspiron 1520 battery in my electric vehicle.

2.5. Of electric vehicles, electric car driving device

Electric vehicles, electric car driving device which is driven by the motor torque through the wheels into force on the ground, the drive wheels running. It with other vehicle components are the same, by the wheels, tires and suspension components Pavilion DV4 Pavilion DV5 Pavilion DV7, Pavilion DV3000 and so on.

2.6. Of electric vehicles, electric car steering

Electric vehicles, electric cars for the realization of a special device is a vehicle set up by the turn by turn to drive, steering wheel, steering wheel and steering components, etc.. The role of control in the steering wheel through the steering and steering tilt steering wheel so that a certain point of view, towards the achievement of motor vehicles. Most electric vehicles for the front wheel steering, electric industrial forklift with rear-wheel steering is often used. Electric vehicles are equipped with a mechanical steering steering, hydraulic steering and hydraulic power steering VGP-BPS8 VGP-BPS9 VGP-BPS13 and so on.

2.7. Of electric vehicles, electric cars brake

The braking device for electric vehicles and other motor vehicles, is to slow down or stop and the car set up, usually by the brake control device and its components. In electric vehicles, the general also electromagnetic brake, which can be used to control motor-driven electrical power generation circuit to run, so that when the braking deceleration of energy conversion into the current battery, which has been recycled.

2.8. Electric Vehicle electric cars work device

Electric vehicles, electric cars is the work of installation of industrial electric vehicles operating requirements for the completion of specialized settings, such as electric forklift lifting devices, door frames, forks and so on. Fork lifting and tilting the door frame is usually motor-driven hydraulic systems.
