Byd high voltage energy storage wiring harness

What is a high voltage wire harness?

The high-voltage wire harness can be divided into motor HV wiring harness, battery high voltage wires, and fast charging high voltage wires etc. It mainly provides high-voltage power supply for new energy vehicles.

What is EV wire harness design?

Its design mainly involves the working voltage, working temperature, temperature rise, wire diameter, cable protection and the selection of high voltage connectors. The working voltage of an EV wire harness refers to the maximum voltage that can be safely applied to the wires in a specific wire harness.

What is the working voltage of an EV wire harness?

The working voltage of an EV wire harness refers to the maximum voltage that can be safely applied to the wires in a specific wire harness. The rated power of electric motors used in electric commercial vehicles is relatively large -- generally between 50 and 150 kW. It can reach more than 200kW on some electric heavy trucks.

What temperature should a high voltage wire harness be able to operate?

At present, the ambient temperature is generally -40℃ ~ +85℃. The long-term maximum allowable working temperature on the surface of the high-voltage wire harness is 125℃, which can reach to 150℃ in some special applications. When designing EV HV wiring harness, it is required that the operating temperature ≥ ambient temperature + temperature rise.

What factors should be considered when designing an EV HV wiring harness?

The working temperature and temperature rise are two important factors to consider when designing an EV HV wiring harness. Working temperature: it refers to the highest temperature at which it can operate without damage during its normal service life under normal conditions of use.

Can a wire harness be damaged if it is outside rated temperature?

A wire harness can be damaged if it operates outside its rated temperature range because it will generate heat due to its resistance when current flows through it. Temperature rise: it is how much hotter a wire gets after being subjected to high currents over long durations.
