Connection of the Three-electric System in New Energy Vehicles

For the special connection requirements of the three-electric systems (battery, motor, electronic control) of pure electric and plug-in hybrid vehicles, we provide a combined solution of high-voltage, high-current automotive connectors and wafer connectors. This meets the critical application needs such as data sampling and communication connections for the battery management system (BMS), control signal transmission for the motor control unit (MCU), and power connections for the on-board charger (OBC).

Solution Overview

New energy vehicles impose entirely new requirements on connectors: high voltage, high current, and high protection. This solution covers the complete connectivity requirements from sampling connections inside battery modules to vehicle controller communications, including high-voltage connectors, low-voltage signal connectors, and Wafer wire-to-board connectors.

Main Application Areas

Battery Management System BMS: Cell voltage sampling harness, temperature sensor connection, CAN communication bus, balancing control line
Motor Control Unit MCU: Resolver sensor signals, IGBT drive, temperature detection, three-phase current sampling
On-Board Charger OBC: AC input interface, DC-DC converter control, high-voltage DC output
High-Voltage Power Distribution Unit PDU: Main relay control, pre-charge circuit, current sensor connection, fuse holder

Solution Advantages

The full product series is certified to QC/T-1067 and ISO 16750; the High Voltage Interlock Loop (HVIL) function ensures operational safety; compliant with the LV214 international automotive connector standard.
