Parts supplier borgwarner has built a prototype of a high-voltage all-electric vehicle to demonstrate its full range of electric-drive system development capabilities. The prototype car is equipped with traction inverter, torque vector rear drive unit, electronic cooling water pump, vehicle and traction control software, dc/ac converter and high-voltage battery pack and other technologies and components developed by bg-warner.
To provide a dynamic and controllable driving experience, the vehicle's electric vehicle powertrain can improve steering response speed through a torque vector rear drive unit and allow forward drive and braking energy recovery. In addition, borgwarner thermal management system technology enables the cooling fluid circulation of the inverter and battery pack via electronic water pumps. The 350V, 30kWh liquid-cooled battery pack has a peak output of 200kW.
The prototype car also USES a 250-kw high-voltage power card motor developed by Cascadia Motion, a subsidiary of borgwarner, and an electric-driven rear wheel drive system for a variable-speed bridge to control each rear wheel independently. The system also USES two borgwarner inverters for full control of the vehicle to enhance its power and durability.
"Borgwarner electrified products"
A joint venture between borgwarner and Romeo Power provides the prototype with a variety of battery configurations that can be tested and validated for specific vehicle development goals or driving experience requirements. In fact, the borgwarner team built the prototype in just six months. The car is equipped with advanced electric drive technology and an open design, making it easy to install and disassemble parts.
"The new high-voltage pure electric prototype demonstrates borgwarner's ability to develop electrification." Hakan Yilmaz, vice President and chief technology officer of borgwarner, said, "borgwarner will continue to work on projects similar to this electric prototype to help validate the next generation of products."
