Background

About Diah Wulandari

I’m a Powertrain Engineer with strong hands-on experience in vehicle electrification and heavy-duty off-highway systems, I specialize in optimizing powertrain configurations and simulation—diesel, electric, and hydrogen dual-fuel—for commercial vehicles, with a focus on performance, safety. Experienced also in vehicle data troubleshooting and programming with CAN based protocol, using Vector CANOe/CANAnalyzer. Lead engineer for the development of retrofit electric commercial vehicles. Skilled in: Matlab, Simulink, powertrain simulation, pneumatic brake system simulation and testing, CAN programming, vehicle integration, project management, Computer-Aided Design (PTC Creo, SolidWorks, Autodesk Inventor), and Manufacturing. I also conduct in-depth financial modeling for EV retrofits and hydrogen engine conversions. Engineering professional with a Master’s Degree focused in Automotive Engineering from RWTH Aachen University and Bachelor's Degree in Mechanical Engineering from Institut Teknologi Bandung. Outside of engineering, I’m an endurance cyclist and health optimization enthusiast, applying the same analytical mindset to recovery, supplementation, and performance metrics. Currently exploring technologies that integrate real-time testing, predictive modeling, and energy transition strategies for next-gen heavy-duty fleets. Key areas of focus: Powertrain architecture (EV, ICE, H₂ICE, FCEV) Brake and retarder thermal simulation Suspension and axle load dynamics TCO modeling, ROI evaluation, fleet cost optimization MATLAB/Simulink simulation for vehicle systems Hydrogen retrofitting & co-firing strategy Let’s connect if you’re building the future of transport—especially in extreme, off-highway, or electrification-challenged environments.
