Electric passenger cars use connecting high voltage cables to form structures

China [CN]

Automotive high-voltage cables are an important part of the automotive electrical system and are used to transmit high-voltage electrical energy. It connects the engine and ignition system and serves to transmit electrical energy from the generator to the car's ignition. During the operation of the automobile engine, high-voltage cables are subjected to huge pressures of high temperature, high pressure and high current, so they have high temperature resistance, corrosion resistance and wear resistance.

The basic structure of vehicle-mounted high-voltage cables is a complete wire and cable composed of copper conductors, insulation materials, fillers, tapes, twisted pairs, and the outer surface is wrapped by a sheath.

Electric buses are mainly used for transportation convenience, urban buses, intercity transportation, long-distance travel, unit organizations and collective outings, etc.

Electric buses refer to pure electric buses that run entirely on electric energy. Such products have low noise, high driving stability, and zero emissions. Although electric vehicles themselves do not emit pollution, their indirect pollution cannot be ignored. For example, the lead in lead-acid batteries will pollute the environment from mining, smelting and production. Another example is that a large part of the electricity used comes from thermal power generation, and coal fuel can also cause air pollution...

According to the data, the voltage of electric vehicles is generally 336V or 384V; while the voltage of electric buses is generally 580-600V. The higher the bus voltage, the wider the speed range of the motor's constant power.

The design and layout of the vehicle's high-voltage wiring harness also requires corresponding preparations. The main design solutions for the vehicle's high-voltage wire harness include wire harness direction design, wire diameter design, high-voltage connector selection, charging port type and application, shielding design, high-voltage wire harness fixing buckle selection, high-voltage wire trough design, and high-voltage interlocking HVIL and other designs. In terms of design of the high-voltage system, taking into account electromagnetic interference factors, the entire high-voltage system is fully covered by a shielding layer.

According to the characteristics of high-voltage wire harnesses, high-voltage wire harnesses are generally divided with high-voltage electrical appliances as the center, and can be divided into motor high-voltage wires, battery high-voltage wires, charging high-voltage wires, etc. The motor high-voltage line is generally the high-voltage line connecting the controller and the motor; the battery high-voltage line is generally the high-voltage line connecting the controller and the battery; the charging high-voltage line is generally the high-voltage line connecting the charger and the battery.
