The design reduces manufacturing complexity and the number of possible failure points. Tesla’s focus on minimizing complexity and weight leads to greater efficiency and reliability in every car.
Tesla’s simplified wiring harness architecture allows for more robotic automation during production. This change speeds up assembly and reduces errors.
Wiring Harness Design
Tesla integrates wiring harness design with the overall vehicle platform. The company uses flat, modular harnesses instead of flexible round conductors. Local controllers in subassemblies, such as doors, manage devices nearby. This modular approach shortens cable length and reduces complexity. Subassemblies can be pre-assembled and tested before joining the main platform. The Cybertruck’s ethernet-based system connects high-speed controllers, cutting wiring mass by 84%. The backbone structure with specialized cables and connectors improves both power and signal transmission. Tesla’s design reduces the number of wires from 490 in the Model 3 to only 155 in the Cybertruck, even as the number of endpoints increases.
Advanced Features
Advanced features in Tesla’s wiring harness give the company a competitive edge. Many competitors use older connectors and heavier wires, which add weight and increase failure points. Tesla’s clean-sheet design avoids these legacy issues. The market for electric vehicle harnesses is growing as cars need higher voltage systems and more data transmission for autonomous driving. Tesla’s lightweight, modular harnesses support these demands. The streamlined design also prepares Tesla for future 48-volt systems, which will use thinner wires and improve energy efficiency. The new wiring system allows Tesla to adapt quickly, while competitors face more challenges with their older designs.
High-Voltage Wiring Harness
Power Delivery
Tesla’s high-voltage wiring harness plays a crucial role in delivering power efficiently throughout the vehicle. The company uses advanced cables, such as the 150 XLE High Voltage Shielded Battery Cable, which offers flexibility and reliability even in tight spaces. Tesla protects these cables with self-coiling braided sleeves inside the cabin and corrugated conduits in harsher environments, like near the rear drive motor. This approach ensures the high-voltage wiring harness system remains durable and dependable.
Tesla’s transition to a 48V architecture in vehicles like the Cybertruck marks a significant step forward. By increasing voltage, Tesla reduces current, which leads to much lower power loss. This change allows for smaller wires, lighter harnesses, and simpler electronic components. The result is a more efficient high-voltage system that supports the power battery system and modern vehicle features.
