An electric car is a kind of car that uses a battery pack to store electrical energy, and the motor energy can be converted into mechanical energy to drive the car. Its main working principle is as follows: 1. Battery pack energy storage: The battery pack used in an electric car is generally a lithium-ion battery. When the car is running, the battery pack will store electrical energy. In stopping or braking during driving, the energy recovery system can convert part of the kinetic energy into electric energy and store it in the battery pack. 2. Motor conversion: The main power source of an electric vehicle is the motor. When the battery pack releases electrical energy, the motor converts the electrical energy into mechanical energy. The rotating part in the motor turns and drives the tires to achieve the movement of the car. 3. Control system: The control system of electric vehicles has two main parts: the motor control system and the vehicle control system. The electric motor control system can control the speed and output power of the motor so as to realize different driving modes. The vehicle control system can realize the driver's control of the car by controlling the braking, steering and acceleration of the vehicle. 4. Charging system: Electric vehicles need to be charged regularly to ensure the normal operation of the battery pack. The charging system includes a charger and a cable to connect to the grid. When the electric car is connected to the charger, the battery pack automatically receives electrical energy and stores it in the battery pack. Overall, electric vehicles work by storing electrical energy in the battery pack, converting electrical energy into mechanical energy by the electric motor, and controlling the movement of the vehicle and charging system by the control system to achieve efficient and environmentally friendly operation of the vehicle.

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 moving electric vehicles reduce speed or stop driving, or to 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, etc. 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.

With the rapid development of manufacturing industry, China's automobile industry is facing the challenges of industrial transformation, emission reduction, energy crisis and low-carbon development. The development of new energy vehicles has become the only way to reduce the automobile industry's dependence on oil and exhaust pollution. Battery pack is the main energy storage component of electric vehicles, which is composed of lithium batteries, and directly affects the performance of electric vehicles. Due to the limited space for loading batteries on the vehicle, the number of batteries required for normal operation is also large. The batteries will discharge at different rates and generate a large amount of heat at different heat generation rates. In addition, time accumulation and space impact will gather a large amount of heat, resulting in complex and variable ambient temperature conditions for battery pack operation. The temperature rise in the battery pack seriously affects the operation, cycle life, charging acceptability, battery pack power and energy, safety and reliability of the electrochemical system of the battery pack. If the battery pack of the electric vehicle cannot dissipate heat in time, the temperature of the battery pack system will be too high or distributed unevenly, which will reduce the cycle efficiency of battery charging and discharging, affect the power and energy of the battery, and in serious cases, lead to thermal runaway, affecting the safety and reliability of the system; In addition, due to the dense placement of heating battery bodies, there must be more heat gathering in the middle area, and less edge areas increase the temperature imbalance between the cells in the battery pack, which will cause the imbalance of the performance of each battery module and cell, ultimately affecting the consistency of battery performance and the accuracy of battery state of charge (SOC) estimation, and affecting the system control of electric vehicles. Therefore, in order to improve the vehicle performance and maximize the performance and life of the battery pack, it is necessary to optimize the structure of the battery pack and design battery optimization for electric vehicles that can adapt to high and low temperatures.

Electrical principle of AC charging There are three charging modes for AC charging, namely mode 1, mode 2 and mode 3. According to the requirements of national standards and charging safety, mode 1 is strictly prohibited, mode 3 generally adopts the mode of connection mode C, and its mode 2 and mode 3 connect the AC charging working principle of mode C. AC charging is a national standard charging mode, and its electrical schematic diagram, detection and control shall meet the requirements of the standard GB/T 18487.1-2015 Conductive Charging System for Electric Vehicles - Part 1: General Requirements, as shown in Figures 2 and 3. In addition to meeting the requirements of national standards, different automobile manufacturers will add charging prompt or display functions according to project requirements, so as to facilitate customers to view the charging status. Composition of DC charging: DC charging refers to that the voltage input from the external power grid to the vehicle is DC, that is, the DC charging pile converts 380V AC three-phase electricity into DC, and then transmits it to the vehicle through the standard DC charging plug and charging socket to directly charge the power battery to complete the basic DC charging. DC charging components mainly include DC charging socket (DC charging socket harness), vehicle controller (VCU, BMS), DC charging pile, etc. Electrical principle of DC charging: There is only one mode of DC charging, namely charging mode 4 described in the national standard To learn more about electric vehicle lines and charging pile lines, please visit or search: https://www.omgevcable.com

With the increasing use of pure electric vehicles and the increasing demand for charging, the market puts forward higher and higher requirements for the safety and convenience of vehicle charging. Convenient, safe and fast charging is the consistent demand of the market for vehicles. The AC charging socket and on-board charger are fixed on the vehicle, the charging line is delivered with the vehicle, and the AC charging pile is fixed in the parking lot. The functions of each component are as follows: (1) The on-board charger is the key component of the AC charging system, which converts AC power into DC power to charge the battery according to the control command. (2) The AC charging socket is a national standard part, which is the interface for the vehicle to connect to the external power grid. Its interface has two signal circuits, one grounding circuit, one zero line circuit and three live line circuits, a total of seven interfaces. According to the input voltage of 220V AC or 380V AC, the corresponding live line interface is applied. (3) The vehicle controller is the control brain of vehicle charging, which monitors the status of the vehicle, sends control commands to the on-board charger to make it work or stop working, and controls its working current and voltage. (4) The mode 2 charging line is a charging line connecting the external power grid and the vehicle, which directly supplies 220V AC power to the on-board charger. The function box on the cable can detect the status of the vehicle and the power grid, connect or disconnect the power supply to the vehicle, and has certain protection functions. According to the standard requirements, the input charging current is limited to 13A and the input voltage is 220V AC. Therefore, when the charging line in mode 2 is used for charging, the maximum input power of the on-board charger is 2860W, that is, the charging time will be extended. (5) The AC charging pile is also a part of the vehicle connecting to the external power grid, which directly supplies 220V AC or 380V AC power to the on-board charger. It also has the function of detecting the status of the vehicle and the power grid, and connecting or disconnecting the power supply to the vehicle. The power supply voltage of the charging pile is 220V AC and 380V AC, depending on the output power of the charging pile. According to the standard requirements, if the output current of the AC charging pile is greater than 32A, the power supply voltage must be 380V AC. Therefore, when the AC charging pile is used for charging, the charging power is large, that is, the charging time will be shortened.

Limiting the time that electric vehicles need to charge before returning to the road is an important factor to promote its adoption, and many studies have focused on reducing these charging times. A new advance uses alternative cooling technology to remove heat from the charging cable, enabling it to handle the type of current required for electric vehicle charging in five minutes. The charging rate of an electric vehicle depends on the current (and other factors) that the charging cable can handle. The greater the current, the more heat. Everything is very impressive, but do you really need it? All existing technologies can already provide 200-500a current. Recently, I heard from a speech that the person in charge of lucid Peter Rawlinson said that some people would think that the battery capacity of private cars has reached the peak, and the charging time will be shortened in the future with the improvement of infrastructure. Charging a 50 kwh battery at 500A takes only 6 minutes, which is shorter than going to the bathroom or drinking a cup of coffee. Even at the current rate of 150W, it can be fully charged after stopping for 20 minutes. All articles like this promote the myth that charging time is still a problem. Where this technology will have an impact is to charge large batteries needed for commercial freight or shipping.

Climate change refers to long-term changes in temperature and weather patterns. These changes may be caused by natural causes, such as changes in the solar cycle. However, since the 19th century, human activities have been the main cause of climate change, especially the combustion of fossil fuels such as coal, oil and natural gas. The burning of fossil fuels produces greenhouse gas emissions, which act like a blanket around the earth, capturing the heat of the sun and raising the temperature. Facing the future, new energy vehicles will play a greater role in expanding domestic demand and stimulating consumption, providing strong support for accelerating the construction of a new development pattern. Developing new energy vehicles is the only way for all countries in the world to move from a big automobile country to a powerful automobile country. It is a strategic measure to deal with climate change and promote green development. From the perspective of consumption and use, the "new" of new energy vehicles lies not only in new energy, but also in the change of transportation mode. The trend of electrification, intelligence and networking is irresistible. New energy vehicles are not only "four wheels and two rows of sofas", but also intelligent terminals that can be updated automatically, and can also bring people a clearer sky. From automatic driving to intelligent cockpit, from human vehicle interaction to remote control, the intelligent degree of new energy vehicles has been continuously improved to create a more comfortable, convenient and intelligent driving experience. Data show that in China, the proportion of private consumption of new energy vehicles has risen to nearly 70%. More and more consumers take environmental protection and scientific and technological content as important considerations in choosing cars. Facing the future, new energy vehicles will play a greater role in expanding domestic demand and stimulating consumption, providing strong support for accelerating the construction of a new development pattern. From the perspective of supply and production, new energy vehicles bring not only changes in the industry, but also "ecological" changes. The new energy automobile industry is gradually evolving from the "chain relationship" between parts, vehicle R & D, production and marketing service enterprises to a "network ecology" with the participation of multiple subjects in many fields such as automobile, energy, transportation, information and communication. The development of new energy vehicles is driving the transformation and upgrading of manufacturing enterprises in the industrial chain, realizing more cross domain and cross industry resource integration, and becoming a new fulcrum to realize high-quality development.

New energy vehicles have now become a convenient way of travel in our life. Charging piles used to supplement electricity for new energy vehicles are also the normal in life. No matter in companies, communities and other public places, charging piles can be seen in operation. However, what are the characteristics of charging pile cable materials? The following is a brief introduction. As a bridge connecting piles and cars, the performance of charging pile cable is very important. In addition to the outdoor performance of basic cables such as insulation and flame retardant, the overall hardness of the cable should not be too high, because it needs to be bent frequently. The so-called charging pile cable material actually generally refers to elastomeric related materials, used for insulation layer and sheath layer. Material properties require oil resistance, tear resistance, weather resistance, chemical resistance, high and low temperature resistance and softness. At present, the more mainstream is TPU, TPE, PVC elastomer. The following describes the characteristics and differences between TPU and TPE. The English name of TPU is Thermoplastic polyurethane, which means Thermoplastic polyurethane. It is characterized by high strength and good wear resistance, which can not be replaced by other TPE materials. The wear resistance and strength of TPU are much better than TPE, but the hand feel is not as good as TPE. At present, the softest hardness of TPU is about 55A or more. The main characteristics of TPU are: a wide range of hardness, and with the increase of hardness, its products still maintain good elasticity and wear resistance, high mechanical strength, outstanding cold resistance, good processing performance, oil resistance, water resistance, mold resistance, good recycling. TPE has greater elastic loss than TPU at high hardness. TPE is the abbreviation of Thermoplastic Elastomer, which means Thermoplastic Elastomer. It is a special functional material with plastic plasticity and rubber elasticity. Thermoplastic elastomer TPE has high elasticity, high strength, high resilience of rubber, and has the characteristics of injection molding processing, environmental protection, non-toxic safety, a wide range of hardness, excellent coloring, soft touch, weather resistance, fatigue resistance and temperature resistance, can be recycled to reduce costs. The TPE material based on SEBS is prone to low strength, easy precipitation, poor resilience, poor weather resistance and fatigue resistance, and the phenomenon of dripping and smoke in combustion when adding a large number of inorganic flame retardants to improve the flame retardancy. The reduction of these comprehensive properties affects the service life and operation safety of products, and limits the application of low-smoke halogen-free flame retardant TPE materials in the field of electronic and electrical connection lines, especially the materials used in new energy charging pile cables. At present, PVC material is used for most of the insulation protection materials of automobile wiring harness at 105℃ and below temperature level. PVC materials used in domestic automobile wire harness often have shortcomings such as extrusion surface, poor low temperature performance. In view of this, combined with the special environment (such as narrow space, poor environmental heat dissipation, frequent mutual friction, etc.) and special requirements (thin wall, high-speed extrusion, etc.) and cost control requirements of automobile wire harness, it is necessary to study PVC material for automobile wire harness to further improve its performance.

On electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, air conditioning power, etc. It mainly includes battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment and its harness system. Electric vehicle high-voltage line is used to connect charging port and battery, battery interior, battery and engine, other components and battery energy storage equipment. It is used as the carrier of power transmission. The biggest feature of vehicle high-voltage conductor is high-voltage resistance. At present, the high-voltage conductor used in the market is at the high-voltage resistance level of 600V AC / 1000V DC. With the increase of endurance mileage, higher power output is required, and high-voltage conductor with higher withstand voltage level will be required, and the withstand voltage level will reach or exceed the level of 1000V AC / 1500V DC. In addition, for the high-voltage conductor used in the high-voltage and high current module, due to the requirements of high power, interior space and wiring design, the high-voltage conductor has the characteristics of high current resistance, high temperature resistance, flame retardant, high flexibility and EMC anti shielding performance, so as to meet the market application of new energy vehicles. The high-voltage harness has the characteristics of high voltage and high current. As the main energy transmission channel, the high-voltage harness of new energy vehicles needs to bear large current, in which the DC bus can reach more than 300A. And it has sealing property. The environment where the automobile high-voltage cable is located is relatively bad. In addition, the characteristics of high voltage and high current of the high-voltage harness have high requirements for the tightness of the harness, so the product test and air tightness test should be carried out. If the seal is not good, it will lead to moisture or water, which will cause aging and damage of the conductor and connecting parts; If the sealing performance of the plug-in part is poor, the insulation resistance will be reduced and the whole vehicle will report insulation failure.
