Automated power electronics burn-in testers
The work
Rameez owned the automated burn-in and functional test equipment for Tesla’s power electronics end to end: CAD, electrical design, build and validation, with a team of two technicians, plus the integration work that makes a tester part of a factory workflow rather than a machine standing beside it.
The equipment took manufacturing capacity from 15,000 units a year to 100,000 for vehicle and energy storage products. He also led production project ramps for the Model 3 launch, working on site in Reno, Nevada and at supplier factories.
EOL tester for Tesla Powerwall 2, increasing production test capacity 10×. Deployed 20 test stations in China.
7 kW rack-mounted power supplies with regenerative AC loads to prevent resistive heating, custom mechanical pneumatic actuators for high-current clamping of busbars, and temperature, voltage and current sensing via DAQ.
Safety circuitry: high-voltage protection across AC and DC junctions
