  In electric vehicles, the high-voltage electrical system is responsible for starting, driving, charging and discharging, air conditioning power, etc. It mainly includes the battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment, and its wiring harness system. Electric vehicle high-voltage wire is used to connect the charging port to the battery, inside the battery, between the battery and the engine and other components, as well as battery energy storage equipment and other areas, as a carrier of power transmission. Due to the harsh application environment in the vehicle, electric vehicle high-voltage cables have very high performance requirements. Introduction of common standards for high-voltage cables. For example, the standards used in the Chinese region: GB/T 25085 (ISO6722): Single-core cables for road vehicles 60V and 600V Dimensions, test methods and requirements GB/T 12528: AC rated voltage 3kV and below for rail vehicle...

  Introduction: In the process of decomposition of new energy high-voltage harnesses for heavy trucks, a simple analysis of the selection of raw materials, the treatment of the shielding layer and the impact of the wire on the waterproof performance of the plug, a concise explanation of the difficulties of high-voltage wire processing, to provide some reference for the harness process designers. High-voltage wiring harness as a new energy electric vehicle to connect the power battery, drive motor, high-voltage control system of the three core components of the link, is the medium of high-voltage power transmission, is the vehicle's power and signal transmission distribution of the highway, its quality directly affects the power or signal transmission effect and even the stability of the entire vehicle high-voltage system. Therefore, it is getting more and more attention from high-voltage wiring harness manufacturers and component suppliers. Whether it is used in electric vehicles, ...

 Mining car meaning: a type of carriage that is loaded at the point of production and hauled by locomotive or other power to the bottom of the pit or to the surface by train. They vary in capacity and are either of wooden or steel construction or a combination of both. Transporting heavy cargo prevails, and while producing the vehicle, fine and standard is required for the connecting equipment part. Safe passage of the vehicle inspection report. These vehicles, often called Mine-Spec vehicles, must meet specifications tailored to the safety and optional equipment requirements of each mine. Meaning of Heavy Duty Vehicles: Heavy duty trucks are large vehicles used to transport heavy loads. The drivers of these vehicles must be specially trained and licensed. You need a special license to drive a heavy truck. A heavy truck is a truck that exceeds the maximum allowable weight of 7.5 tons. Examples: passenger buses, carriers, livestock and other farm vehicles. Mobile cranes and other sp...

 With the successive development of new energy electric vehicles, there are a number of automobile manufacturers who operate the state of electric vehicle industry products, for example, charging pile construction, charging station operation and other models. The following describes several cases of global operation models: 1: Asset-light operation and automaker-led United States: The main body of charging pile operation mainly includes professional charging facility operators and vehicle enterprises represented by Tesla. Meanwhile, car companies choose to cooperate with professional operators when building private charging piles. 2: Dominated by energy and vehicle enterprises Europe: Charging facilities are operated by a wide variety of subjects. Charging operating enterprises mainly include traditional energy enterprises, car enterprises and electric power companies, etc. They are generally well-financed and operate charging business through self-operation or investment in establ...

  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 transmi...

 The difference is as follows: (a) In terms of current carrying capacity, wire and cable are for carrying small currents, busbars are for carrying large currents; from the structural form, wire and cable is flexible (internal copper core external insulation layer) can be bent, bus bar is rigid (internal rigid copper row external steel or aluminum alloy shell) can not be bent, the need for specially made bend through; From the point of view of the use of characteristics, the installation of wire and cable production trouble, each power equipment need to be independently wired, while the bus bar is easy to install flexible, not easy to install errors, a bus bar can be used for many points of equipment at the same time with electricity. The principle is the same, copper row because of a single flow area is larger so dynamic stability and thermal stability are better than the cable, so the high current load or power supply is generally connected with closed busbar, but because the copp...

 Operating voltage is not the same: 1, RVV full name copper core polyvinyl chloride insulation PVC sheath flexible cable, rated voltage 300/500V. 2, YJV full name copper core cross-linked polyethylene insulation PVC sheath wire and cable, rated voltage low voltage 0.6/1kV, high voltage 6/10KV to 26/35kV. YJV and RVV cable wire commodity name is not the same, the meaning of the representative is not the same, YJV insulation with cross-linked polyethylene, RVV insulation with polyvinyl chloride. Production equipment and processing technology in the manufacture of manufacturing is also different 1, RVV for plastic force cable, YJV that is cross-linked cable, the insulation layer characteristics better than plastic force cable; YJV only in the insulation of raw materials dry chemical cross-linking solution to enhance the high temperature resistance, while RVV no. 2, YJ on behalf of cross-linked polyethylene, this is the type of cable line insulation. 3, V stands for polyvinyl chloride ...
