Our mission: reconcile performance and longevity by helping our clients design innovative and reliable battery systems four times faster, using our digital tools and experimental testing.
Our promise: Kurybees is your technical co-pilot—the expert guiding you to make the best decisions based on your goals.
Kurybees: Powering durability with batteries.
Why this internship is educational
You will learn, in real-world conditions, how to size a battery while taking into account the strong coupling between:
- Electrical behavior (voltage, power, state of charge, internal resistance)
- Thermal behavior (self-heating, temperature limits)
- Aging (calendar & cycling, end of life)
All of this will be applied directly to a variety of use cases: drill, electric scooter, e-bike, and electric scooter.
Internship Objective
Contribute to the improvement and enhancement of an industrial-use-oriented electro-thermal-aging Excel model, and develop a battery pack sizing module ready for client demonstration.
The three main focus areas:
- Optimize and stabilize the existing model (structure, stability, usability, visualization).
- Develop a multi-application module (e-bike, e-scooter, lighting, ESS, etc.) integrating our measurements and real constraints (dimensions, weight, power, energy, lifespan).
- Leverage and showcase the model through case studies, one-page summary sheets, a user manual, and product development recommendations.
For more details, please contact us to receive the complete project description.
Work to Be Carried Out (Summary)
- Audit, correction, and improvement of the existing model
- Development of a calculation and sizing module in Excel based on our internal rules
- Conducting concrete application studies to illustrate the model’s results
- Debugging, documentation, and preparation of the user manual and validation guide
Required Skills
Education: Master’s degree in Electrical Engineering, Energy, Applied Physics, or Modeling (equivalent to Bac+5).
Technical skills:
- Excellent command of Microsoft Excel (formulas, VBA/macros, automation, charts)
- Solid fundamentals in Electrical Engineering
- Knowledge of Li-ion batteries (characteristics, aging) is desirable
- Basics of thermal and electrical modeling
- (Optional) Experience with Matlab/Python for post-processing
Personal qualities:
- Rigor and autonomy
- Scientific curiosity
- Analytical mindset
- Clear communication skills
Expected Deliverables
- Improved and validated version of the Excel model
- Operational sizing module
- Demonstrative application studies
- User manual and validation guide
Expected Deliverables
- Duration: 5 to 6 months
- Location: Écquevilly (78), partial remote work possible
- Supervision: Kurybees R&D team
- Compensation: according to profile and school/Syntec guidelines
