Unlike traditional hydraulic systems, electric power steering (EPS) relies on electrical energy to assist steering, which improves vehicle efficiency and reduces maintenance requirements. In these systems, sensors transmit data to the electronic control unit (ECU), which calculates the required assistance and activates the electric motor.
To ensure a steady and reliable power flow for this process, the ENNOVI-BusMate Power Busbar Connector provides a compact design and a 40-80 amp power density. This enhances power steering efficiency, steering precision, and overall vehicle performance.
What are the Current Capacity Limits in EPS Systems?
To ensure a steady and reliable power flow, the Power Busbar PCB Connector: ENNOVI-BusMate supports power densities from 40 to 80 Amps.
Unlike traditional hydraulic systems that run pumps all the time even when you are not turning, EPS uses an electric motor to provide steering assistance and only uses power when needed, saving energy. The connector’s 40-80 amp power density enhances power steering efficiency, thereby boosting steering precision and overall vehicle performance.
How do These Connectors Achieve High Ampacity-to-Size Ratios?
Small in size, highly reliable, enormously assembly-friendly, and with a large ampacity-to-size ratio, the Power Busbar PCB Connector: ENNOVI-BusMate enables compact and robust power assembly designs. Its ultra-small footprint conserves PCB space in your assembly, affording huge flexibility for your design options while delivering high power density in high-voltage applications.
How do Power Connectors Perform Under Technical Stress?
The Power Busbar PCB Connector: ENNOVI-BusMate supports power densities from 40 to 80 Amps and features a high-temperature construction. In validation tests for current rating, the 9 Lam. PF configuration demonstrated a constant current at 55°C ROA of > 40Amps and an average of > 60Amps, while the 14 Lam. SMT configuration achieved > 77Amps. In addition, the connector passes validation tests for mechanical shock, vibration with thermal cycling, and thermal shock, ensuring reliable performance in high-voltage applications.
What Routing and Integration Options are Available?
Engineers require versatile routing options to fit complex EV architectures and diverse sub-assembly requirements.
High-capacity power connectors offer multiple mating configurations, including board-to-blade, board-to-board, and blade-to-blade setups. They are designed for compatibility with standard 0.8mm to 1mm thick busbar blades.
Floating contact technology is a key feature in these systems. This technology maintains electrical integrity by automatically compensating for busbar misalignments and stack-up tolerances in sub-assemblies. These solderless interfaces simplify the assembly process and reduce the risk of poor connections or cold joints associated with traditional soldering.
How is the Future of EPS Impacted by Interconnect Innovation?
Electric power steering (EPS) systems require tight integration of complex power and signaling between multiple modules. Our integrated solutions enable EPS systems that are smaller, lighter, and more robust. Power distribution in EPS systems needs to be rock-solid to ensure smooth performance. That’s where power busbars come in: they keep energy flowing efficiently with minimal losses.
