Introduction to the fundamentals of new energy electric vehicle operation

 Basic components of a pure electric vehicle


Electric motor: The power device of electric vehicle, which is an electromagnetic device to realize electric energy conversion based on the principle of electromagnetic induction, and is represented by the letter M in the circuit. Its main function is to generate rotational motion and serve as a power source for electric equipment or various machinery.


Generator: The main role is to convert mechanical energy into electrical energy, it is represented by the letter G in the circuit.


Cooling system: It usually consists of radiator, water pump, fan, thermostat, coolant temperature gauge and water drain switch. Electric vehicle engine adopts two cooling methods, namely air cooling and water cooling, and usually electric vehicle engine mostly adopts water cooling.


Transmission system: pure electric car chassis, because its electric motor has good traction characteristics, so the battery car transmission system does not need clutch and transmission. Speed control can be achieved by the controller through the speed control system to change the speed of the electric motor.


Driving system: The driving system is similar to the fuel car, mainly including frame, axle, wheel and suspension. The role of the driving system of electric vehicle is to receive the torque transmitted by the electric motor through the transmission system, and through the adhesion between the driving wheels and the road, the traction force of the road surface of the electric vehicle is generated to ensure the normal driving of the whole vehicle. In addition, it should moderate the impact and vibration caused by the uneven road surface as much as possible to ensure the normal driving of the electric vehicle.


Steering system: The role of electric vehicle steering system is to maintain or change the driving direction of electric vehicles, which includes steering manipulator, steering gear and steering transmission mechanism and other components. The steering system consists of steering wheel, steering gear, steering knuckle, steering knuckle arm, cross tie rod, straight tie rod and so on. When the electric vehicle is steering and driving, it is necessary to ensure that there is a coordinated turning angle relationship between the steering wheels. By manipulating the steering system, the driver can keep the electric car in a straight line or in a turning state, or switch between these two states of motion; and also ensure that the steering wheels will not self-vibrate, the steering wheel will not swing, the steering is sensitive, the minimum turning diameter is small, and the handling is light.


Braking system: The braking system is the general name of all the braking and deceleration systems equipped with electric vehicles, and its function is to make the driving electric vehicles reduce speed or stop driving, or make the already stopped electric vehicles remain motionless. The braking system includes brake and brake transmission device. Modern electric vehicle braking system is also installed with brake anti-lock device and so on. Similar to fuel vehicles, the braking system of pure electric vehicles also consists of two sets of devices: the running brake and the parking brake.


Of course, the car connection equipment is driven by the above parts to drive driving, and other vehicle equipment has many different functional roles one after another.（# EV charging cable） Need to know more, you can search or visit: https://www.omgevcable.com

Description of cable requirements for electric vehicle charging modes

 With the development of science and technology, as a means of transportation for daily travel, cars will continue to change in the future trends. Among them, electric vehicle charging connectors and charging cables have become a trend for the development of electric vehicles. Electric vehicles generally have two charging connection methods, one is the vehicle's built-in matching charging connector, and the other is a common charging pile in public places. Compared with the charging pile that comes with the car's own charger, which charging efficiency is more efficient? First of all, compare the charging connectors of electric vehicles with charging piles: household appliances are all 220V, and the same is true for appliances with charging piles. Because the input power of the power supply is limited, it takes longer for the car to come with its own charger. On the contrary, charging piles in public places use three-phase alternating current, and the input power can reach 380V,...

Learn more about the development history of OMG cable manufacturer

 In modern society, cables play an obvious role in life. In the early 20th century: Simple cables based on copper wires began to be used for charging electric vehicles. However, the cable transmission efficiency and safety of this period were poor, making it difficult to meet the growing charging needs of electric vehicles. In the following decades: cable design was continuously optimized, using highly conductive metals, multi-layer insulation and intelligent control technology to significantly improve performance. Cables during this period had significant improvements in transmission efficiency and safety. International standardization: With the rapid development of global charging infrastructure, a number of international standards and specifications for cable connections have been introduced, laying the foundation for the standardized application of electric vehicle charging cables . These standards regulate the design, manufacturing, testing and use of cables to ensure safety a...
