About Me

I'm Henry Cheng, graduated from National Chung Hsing University with the ranking 3rd in the department and hold a Master's degree with a major in Chemical Engineering, which was awarded to me by National Tsing Hua University. Besides my major, I take many courses in the electrical field, including electrochemistry and circuitry, which have prepared me for being a battery engineer.

In Aleees, I've held 4 material R&D projects and established a new testing method. In DynaPack, I've participated in 10 battery pack design projects of Light EV, and 50+ failure analysis of the battery pack (IT, non-IT).

Curiosity and necessity are the mother of invention. Delving into electrochemistry, I have published 4 SCI papers and 1 patent in my battery career. Along with these experiences, I hope to develop myself to keep pace with the changes of the era in my profession.

Experience

Cell R&D Engineer - DynaPack [2020/4 - Now]

Light EV Main Project Owner (Cell)
