Welcome to TechNotes

TechNotes is an open engineering library focused on clean tech - specifically electric vehicle (EV) battery technology. Our goal is to combine data, reference articles, design examples, datasets, patents, technical drawings, and discussion forums together in one integrated resource that's exceptionally easy to use and well-organized.

We are currently working to develop our platform and populate example content. For now, you can check out "18650 cell" or "AA battery".
