Hava Temel

A detail-oriented and analytically driven Energy Systems Engineering graduate who builds data-driven predictive models for battery diagnostics and lifecycle estimation. For her graduation project, developed a BiLSTM-based digital twin for lithium-ion battery State of Health estimation, achieving 2.85% MAPE and R² = 0.93 in validation, and presented the work at DATAMACLEA'26 International Conference and TwinBat Summer School (Horizon Europe-affiliated). Pairs this research foundation with field experience in EV charging infrastructure operations, bringing both analytical rigor and practical, on-the-ground understanding to battery technology and Battery Management Systems (BMS).

Undergraduate Researcher, Battery Digital Twin Project at AYBÜ ENERGY SYSTEMS ENGINEERING DEPARTMENT (2025-09 – 2026-06)

Developed a data-driven digital twin for lithium-ion battery State of Health (SOH) estimation using a BiLSTM (Bidirectional Long Short-Term Memory) architecture trained on the NASA PCoE dataset. Owned the full pipeline from raw signal cleaning and feature engineering through model training and End-of-Life (EOL) / Remaining Useful Life (RUL) estimation logic.

• Achieved 2.85% MAPE and R² = 0.93 in SOH prediction, validated across 4 unseen battery units.
• Presented the study as an oral presentation at DATAMACLEA'26 International Conference (Online Session, May 2026) and submitted the full paper for publication (June 2026), co-authored with Furkan Soysal.
• Presented the project as a poster at TwinBat Summer School, Gebze Technical University (June 2026), a Horizon Europe-funded initiative, engaging directly with international battery researchers and academics.
• Defended the graduation project before the departmental jury (June 2026).

Field Operations Engineering Intern at ONIZŞARJ (2025-06 – 2025-09)

Provided technical support across EV charging station installation processes, from site survey through infrastructure preparation, mounting, and commissioning.

• Supported multi-site EV charging infrastructure installations, ensuring technical processes met target standards.
• Coordinated with field teams and stakeholders to maintain smooth progress across installation and commissioning phases.
• Contributed to the information flow between field operations and marketing functions for EV charging initiatives.

Undergraduate Lab Intern at AYBU ENERGY SYSTEMS ENGINEERING DEPARTMENT (İŞKUR Program) (2025-03 – 2025-06)

Worked within the department's education laboratory through the İŞKUR internship program.

BSc in Energy Systems Engineering – Ankara Yildirim Beyazit University (2021-09)
