Welcome to TechNotes

TechNotes is an open engineering library focused on clean tech - specifically electric vehicle (EV) and 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.

Why TechNotes?

Move faster with a technical knowledge base.

Build vs. buy? What's the best technology to use? Let TechNotes be your guide so you can make decisions faster based on up-to-date information.

Got a technical problem to solve? Explore the inter-linked entries in our database to see how others have solved similar problems, and save yourself from re-inventing the wheel.

We are currently working to develop our platform and populate example content. See "18650 cell" for a sample entry, and follow its links for more.
