Frequency-Based Parameterization of Semi- Empirical Models for Health Estimation for EVs
Colin Jie Chu, 18, of Palo Alto, developed a way to predict the health and lifespan of electric vehicle (EV) batteries for his Regeneron Science Talent Search physics project.

Batteries used in EVs degrade over time and pose a risk to the environment and safety while driving. However, it has been hard to predict a battery’s health in real-world driving conditions. For his project, Colin assessed data from 22 batteries that were deliberately aged over time using electrical signals, mimicking vehicle driving behavior, to evaluate how well electricity moved through them.
Using these responses, he developed a model to predict the battery’s state-of-health, using equivalent circuit models and machine learning techniques. His model accurately predicted a battery’s state of health with an error margin of 2.36%. Understanding a battery’s health could improve EV battery safety, lifespan and maintenance costs.
The child of Shelley Chu, Colin attends The Nueva School (San Mateo), where he is co-captain of the physics research team and president of the environmental engineering club. He is also the co-founder and president of Homeless Heroes, a nonprofit focused on food recovery and food insecurity.
Beyond the Project
Colin served as Co-Chair of the U.S. Youth Action Council for the UN Ocean Decade. He has visited Washington, D.C. to lobby lawmakers on ocean legislation and funding, including for five environmental bills.
FUN FACTS: Colin is in the Stanford Water Polo Club and plays the French horn in the Golden State Youth Orchestra. He has visited almost every national park in the United States.
