Engineering Projects
Welcome to my engineering portfolio! Here, you’ll find a collection of my projects and experiences, including my work at Ballard. Each project was a unique challenge and an opportunity for growth.
Ballard Power Systems 70kW Test Cart Internship Project
Internship Role: Electrical Engineer
-
Purpose: Designed and assembled a 70kW test cart to assist in troubleshooting and testing for the team.
-
Electrical Setup: Installed a 35A fuse for high-voltage protection, safeguarding the system against overcurrent scenarios.
-
Power Distribution: Organized wiring into positive and negative sections using 10 AWG wire, ensuring stable power flow.
-
Component Integration: A 36V, 40A power supply was used to power the entire setup, ensuring reliability.
-
Mechanical Work: Utilized tools like a Dremel and drill for mounting and assembly tasks, including drilling holes for custom mounts.
-
Functional I/O Check: Utilized digital multimeters (DMMs) for precise continuity testing and oscilloscopes for in-depth signal analysis on faulty or misaligned valves.
-
3D Modelling: Utilized AUTOCAD and Tinker Cad to create cart design and custom mounts for electronic parts.
-
Team Collaboration: Worked closely with team members to refine the design and implementation, ensuring the cart met project requirements.

-
Team Achievement: Won 1st place in the CSIS competition at Ballard Power Systems.
-
Award Received: Honored with the Shanna Knights Award for the "farthest out-of-the-box idea that was well-considered, where risk is valued and success or failure is not a criterion."
-
Tools and Equipment: Utilized a spectrum analyzer to measure electromagnetic interference (EMI), employed a BCI (Bulk Current Injection) cart to generate EMI noise, and used an antenna probe to capture and analyze signals with the spectrum analyzer.
-
Project Focus: Addressed the issue of electromagnetic interference (EMI) in electronic systems where an electronic system can act like an antenna and generate an electromagnetic field.
-
Innovation: Integrated an EMC shielding spray to mitigate noise emitted by electronic components.
-
Technical Approach: Applied noise of 90Mhz and current intensity of 100mA Applied conductive spray to reduce electromagnetic interference (EMC) and create a larger attenuation.
-
Team Impact: The project contributed to a more robust, noise-resistant design, showcasing innovation and efficiency.

Electrostatic Discharge (ESD) Mitigation and Troubleshooting
Intership Role: Electrical Engineer
-
Purpose: To manage static discharge buildup that could potentially damage the surrounding electronic components of a module.
-
Tools and Equipment: ESD measuring meter to detect high static discharge areas, and oscilloscopes to monitor ESD buildup and signal fluctuations at 250 nanoseconds.
-
Implementation Against ESD: Ground electronic components to the chassis and apply conductive tape(aluminum tape) around the plastic enclosures to ensure proper grounding.
