Delphi Automotive engineers will outline solutions to the emissions challenges facing both gasoline and diesel vehicles in technical papers presented at the 21st Aachen Colloquium (October 8-10) in Germany.
Delphi’s papers describe the company’s near production-ready Selective Catalytic Reduction (SCR) dosing system that provides a “uniquely cost-effective” approach to urea injection, and a Gasoline Direct Injection Compression Ignition (GDCI) engine that is currently in advanced development. The papers will be complemented by extensive hardware displays including a range of new, light-weight power electronics products for hybrid and electric vehicles.
Power electronics products displayed will include Delphi’s high-performance inverter, DC/DC converter, on-board battery charger, battery management system and hybrid vehicle control unit.
Delphi’s inverter uses patented power silicon packaging to reduce cost, size and weight while increasing overall reliability. The packaging eliminates wire bonds, enables higher current and power density, and when combined with dual-side cooling, reduces power semiconductor area. The inverter is expected to start production in 2013.
Delphi’s battery pack controller calculates state-of-charge, evaluates battery health and determines power available for the vehicle. Using these calculations, it performs cell balancing to maintain cell safety and increase battery life. Delphi’s battery pack controller is scalable, AUTOSAR capable, low cost, compatible with multiple cell chemistries and is already in production.
Delphi says its electrical and electronic architecture systems help keep drivers and service technicians safe in hybrids’ and EVs’ high voltage environments with physical harness protection systems, battery monitoring devices, plug-in charging systems and a series of connection systems that incorporate the shielding, sealing and high-voltage safety interconnects.
