Battery Testing Engineer Internship, Powertrain Engineering Europe (m/w/d)

What To Expect
The Battery Reliability Test team is seeking a highly motivated intern to perform high-voltage battery tests. You will focus on hands-on battery testing and support design of battery test equipment. You will work closely with senior engineers to execute complex tests, build fixtures, and analyze data in a fast-paced environment. At Tesla, scope and complexity of your assignments are limited by your aptitude, not seniority or title.

What You'll Do

Execute battery reliability testing that simulates realistic, accelerated lifetime, and environmental conditions on the battery pack and electrical, mechanical, and thermal sub-systems according to Standard Operating Procedures (SOPs).

Design and build mechanical and electrical test fixtures for battery system and component testing.

Develop test software to streamline execution, data collection and analysis.

Work with the cross-functional team to identify failure modes and generate reliability test plans.

Process raw test data to help draw meaningful conclusions and assist in preparing high-quality reports for internal technical teams

Participate in destructive teardowns for root-cause analysis, meticulously documenting findings and observations.

Collaborate with test technicians to achieve test objectives.

Contribute to organizational tasks & responsibilities like creation & maintenance of procedures, SOPs, standards, equipment, inspections, lab commissioning, facilities, maintenance and staff trainings.

Acquire knowledge about relevant industry standards, testing guidelines, and norms.

Tasks require working with high-voltage (live batteries) and other hazardous energy using mandated PPE and procedures and to set up and perform tests in person and in lab environments.

Other tasks as required.

What You'll Bring

Pursuing a degree in a relevant field (Mechanical, Electrical, Automotive, Chemical Engineering, Mechatronics, Physics, or similar).

Strong knowledge of engineering first principles

Basic understanding of multiple of the following: statics, mechanics, linear circuits, digital systems, heat transfer, fluid dynamics, or measurement and instrumentation

Familiarity with coding/scripting for test automation purposes, preferably Python.

3D Design/CAD skills and creation of fundamental wiring and hydraulics diagrams are required.

Fluency in English; German is a plus.

A proactive, safety-first attitude with the ability to work effectively in a dynamic, fast-paced lab environment.

Exceptional organization and communication skills (both written and verbal).

Ability to work independently in a safely critical environment.

Additional Preferred Skills

Initial experience in an OEM or equipment/machine manufacturer is a plus

Experience with CAD software (3D mechanical or electrical PCB)

Experience using electrical or mechanical test equipment: multimeters, power supplies, DAQs, instron, leak testers, fatigue testers, etc.

Project management experience or foundations are a plus
