Copper busbars are an important component of new energy vehicles, serving as electrical conductors. The main raw material is red copper, which is prone to heat generation. Generally, it is necessary to design copper busbars with a larger cross-sectional area. However, this not only increases the size of the design, but also requires more investment in costs.
The research and development of electric drive systems is crucial for the development of electric vehicles. Batteries are an important on-board energy source and a guarantee for the safe operation of electric vehicles. The failure of the electric drive system is the key to inducing car safety accidents, and the design of copper busbars in electric drives requires compliance with many safety rules.
Copper busbars are an important component of the electric drive system of new energy vehicles, so how to calculate their cross-sectional area?
Under the condition that the size is not affected, copper busbars with a larger cross-sectional area are generally selected to complete the relevant design. The cross-sectional area and temperature rise of copper busbars are important factors affecting their current carrying capacity, and the cross-sectional area of copper busbars is calculated based on overcurrent and current carrying capacity.

Based on the actual working environment of the copper busbar and the characteristics of the manufacturing raw materials, the maximum temperature allowed for the copper busbar should not exceed 105 ℃. The temperature set for the test environment should be the average temperature inside the controller box. The allowable temperature rise of the copper busbar describes the temperature for a long time after the copper busbar reaches thermal balance under rated working conditions.
YIPU Metal is a manufacturer of new energy copper busbars, mainly used for electric vehicle battery packs, for battery connections, and for current transmission and electrical equipment connection in circuits. The most commonly used is laminated soft copper busbars, which not only effectively dissipate heat, but also reduce the vibration generated by cars and the impact on battery electrodes.
