Product Introduction
This Bus Bar For EV Control System is designed for power distribution and DC link connections in electric and hybrid vehicle control systems. It is commonly applied in film capacitor assemblies, motor control units, and automotive power electronics architectures, including Film Capacitor Busbar for HEV / EV Motor Control Unit and busbar electric vehicle applications.
Material Standards and Copper Grade
The busbar is manufactured from electrolytic tough pitch copper compliant with multiple international standards to ensure consistency in conductivity and mechanical stability:
GB: T2 Copper, ≥99.9% purity
DIN: E-Cu58 (No. 2.0065)
EN: Cu-ETP (CW004A)
ISO: Cu-ETP
UNS: C11000
JIS: C1100
BS: C101
Alternative copper alloys or material grades can be selected according to current density, temperature rise limits, or structural constraints.
This material system is commonly used in Copper Busbar for DC link EV Film Capacitor and Copper Busbar for Electric Vehicle Capacitors due to its stable electrical characteristics.
Electrical and Mechanical Performance
Electrical Resistance: ≤ 0.00001 Ω
Low resistance minimizes conduction losses in DC link capacitor circuits and supports high-current transient conditions.
Electrical Conductivity: ≥ 97% IACS (at 20 °C)
High conductivity is essential for the busbar for Power Capacitor systems, where current ripple and thermal accumulation must be controlled.
Tensile Strength: ≥ 500 N
Ensures mechanical integrity during assembly, vibration, and long-term vehicle operation.
Material Hardness: HV 80–110
This hardness range balances formability and structural rigidity, enabling precision bending while maintaining mounting stability.
Rivet Nut Specification and Mechanical Fixation
Rivet Nut Brand: PEM (USA standard)
Mechanical fixation performance follows PEM thrust force and torque specifications:
| Bolt Size | Torque (N·m) | Thrust Force (N) |
| M3 | 0.9 | 280 |
| M4 | 2.37 | 300 |
| M5 | 3.0 | 300 |
| M6 | 5.0 | 500 |
| M8 | 6.0 | 800 |
FAQ
Q1: Are samples available, and what is the lead time?
Samples are available for evaluation. Typical lead time is 5–7 days, depending on material grade and structural design.
Q2: Is OEM customization supported?
Dimensions, hole patterns, plating type, and identification marking can be customized based on application requirements.
Q3: What payment terms are commonly used?
Standard terms include T/T and irrevocable L/C at sight. For regular orders, 30% advance payment and 70% balance against B/L copy is commonly applied.
Q4: How is delivery arranged?
Shipment can be coordinated through a designated forwarder in China or arranged directly by international express, air freight, or sea freight.
