As the new energy vehicle industry develops rapidly, the Battery Management System (BMS) serves as the core of vehicle energy control. It operates continuously under harsh automotive conditions including extreme temperature fluctuations, persistent vibration and complex electromagnetic interference.
For the BMS of a new passenger vehicle model, reliable board-to-board connection is required between the main control board, voltage acquisition boards and temperature sampling modules for signal and power transmission. The connector is subject to stringent requirements on stability, weather resistance, vibration resistance and electrical safety. Adopting the industry-standard 2.54mm pitch design, the solution balances universal compatibility, assembly efficiency and convenient maintenance.
2.54mm right-angle pin headers are selected and used together with matching female headers:
• Standard 2.54mm pitch with multiple pin configurations, meeting the demand for multi-channel signal acquisition of BMS.
• Made of copper alloy with nickel underlayer and gold plating, delivering excellent anti-oxidation and anti-salt spray performance.
• 90° right-angle design for side wiring, ideal for compact internal layout of BMS enclosures.
• Operating temperature range: -40℃ ~ +125℃. Reinforced pins withstand long-term vibration during vehicle operation.
• Stable transmission: Low contact resistance ensures real-time and accurate transmission of battery voltage, current and temperature data without signal interruption.
• High compatibility: The 2.54mm standard pitch fits mainstream PCB designs, simplifying assembly and maintenance work.
• Superior environmental resistance: Passed automotive-level tests for temperature cycling, vibration and salt spray. The headers resist oxidation and loosening, effectively reducing equipment failure risks.
• Cost efficiency: As a standard component with stable supply and cost advantages, it fully supports large-scale mass production.
With proven performance, our 2.54mm pin headers have been mass deployed in BMS of multiple passenger vehicles, acting as a preferred connecting component for automotive electronics of new energy vehicles.
