Product Introduction

The automotive battery terminal bar (ABTB) is a key conductive component connecting battery cells and buses in new energy vehicle power batteries, traditional vehicle starting power supplies, and energy storage systems. Its primary function is to achieve high current conduction, stable connection, and low-impedance output, making it a core component that determines the stability and safety of the vehicle's power supply.
The development of new energy vehicles and smart grids has placed higher demands on the terminal bar's electrical conductivity, corrosion resistance, structural stability, and assembly precision. Our company's proprietary automotive battery terminal bars utilize highly conductive copper as a base material and incorporate precision stamping and welding processes. They achieve internationally advanced levels of electrical conductivity, thermal stability, and mechanical strength.
Key Features & Advantages
| High conductivity ensures efficient energy transmission | Utilizing high-purity oxygen-free copper (Cu ≥ 99.9%) or high-conductivity copper alloys, precise surface treatment and plating processes effectively reduce contact resistance, achieving stable, low-loss conduction. Suitable for high-power output scenarios, this ensures continuous energy delivery for vehicle battery systems. |
| Corrosion-resistant design extends service life | Battery environments are often subject to fluctuations in electrolyte vapor, temperature, and humidity. Our terminal blocks utilize tin, silver, or nickel plating as a protective layer. We can also add an anti-oxidation coating upon request to enhance sulfurization and salt spray resistance, ensuring excellent electrical performance even in harsh environments. |
| High mechanical strength and stable and reliable connections | The product structure has been verified through mechanical simulation and fatigue testing, demonstrating excellent vibration and fatigue resistance. The terminal and automotive power busbar connections utilize an integrated precision stamping and welding process, eliminating the risks associated with loosening and overheating that are common with traditional bolted connections, and significantly improving connection stability and safety. |
| Precision Assembly and Custom Compatibility | Compatible with a variety of vehicle models and battery module layouts, we can customize various shapes, hole pitches, thicknesses, and current-carrying capacities based on customer design drawings. CNC machining ensures dimensional tolerances within ±0.05mm, ensuring a precise fit with battery terminals or Capacitor laminating bus bars. |
| Excellent Thermal Management | The conductive strips have low surface thermal resistance, quickly dissipating heat generated during operation and preventing contact overheating and energy loss. This is particularly important for high-rate charge and discharge scenarios, effectively extending the overall life of the battery pack. |
