High-Voltage Module & Control Box Connection System for EVs
An EV’s battery is the core of the car’s drivetrain. Battery packs rely on failproof connections that can transfer high levels of current and voltage during charge cycles and dynamic acceleration over the course of the car’s lifespan.
TE Connectivity’s BCON+ high-voltage connection system is a compact , highly functional, low-resistance bolt termination system for connecting modules and control boxes in traction batteries. Each module is connected to the battery system via bolted terminations made of busbars or cables that can carry 500 amps or more of continuous current for several minutes (depending on busbar/cable size and cooling configurations). The connectors are automation-ready, available in a variety of geometries and conductor connections, and can be easily mated and unmated during assembly or service with IPxxB touch safety.
