Back to original languageAbout Théophile
Doctor Engineer specializing in energy storage systems with experience in Li-ion batteries and hybrid battery/supercapacitor solutions.
I address high-value-added issues, ranging from the analysis of data from test benches to the sizing and optimization of energy storage systems.
I have notably designed and developed prototypes of hybrid power sources (48V – 10 kW), integrating electrical architecture, power converters, instrumentation, and energy management strategies (EMS). Strong aptitude in electronics, microcontroller programming, and control systems (PID, MPC).
🔧 Areas of intervention:
• Battery data analysis (aging, performance, SOC drift)
• Modeling and model identification
• Preliminary sizing of storage systems
• Optimization of energy management algorithms (EMS)
• Battery / supercapacitor hybridization
🛠️ Tools: Python, Matlab/Simulink
👉 My goal: to transform your data into actionable decisions and improve the performance, lifespan, and reliability of your energy storage systems.
I am available for all types of assignments, short, ad-hoc, or long-term. If you have an issue, a project, or an idea, do not hesitate to contact me.
