Bridgold: Leading China Suppliers for EV Control System Components from Our Modern Factory
Deep Experience in EV Control Systems
With over 40 years of expertise in copper busbars and braided wires, we possess in-depth knowledge of the challenges faced by EV control systems (inverters, OBC, DC/DC, PDU, etc.)—high-frequency switching noise, limited enclosure space, severe thermal cycling, and road-induced vibration. From material selection and structural design to insulation withstand and temperature-rise validation, we offer customized solutions throughout the entire design cycle, strictly complying with automotive industry standards.

Product Details (Core Functions of Copper Busbars)
Copper busbars deliver three core functions in EV control systems:
Connecting inverters and drive motors for efficient and stable power transfer.
Equalizing enclosure and structural potentials while providing safe leakage protection paths.
Preventing rigid connections from fatigue failure due to temperature changes and shocks.
Low parasitic inductance effectively suppresses IGBT/SiC turn-off overvoltage, protecting power devices; the flat structure significantly reduces enclosure depth and increases power density; custom L/Z shapes fit compact layouts.
Ultimate flexibility with an extremely small bending radius, absorbing complex vibrations and displacements between modules; the braided structure distributes stress to resist high-frequency fatigue; the open surface area enhances heat dissipation; high tolerance greatly simplifies assembly.
Manufactured from high-purity T2 copper via rolling or extrusion, offering extremely high current-carrying capacity and strong mechanical rigidity. With a fixed form, they are ideal for main-circuit busing connections, delivering superior cost-effectiveness for standardized mass production.
