Putting content in the right order and hitting the right abstraction level.

Keeping the reader/user in the zone between being bored and overwhelmed while you teaching them, without knowing something about them (only data as feedback if they are using a tool that you built,rather than them raising eyebrows or nodding in a classroom).

I think it's hard but also fun. For the EV stuff that I look at there are a few problems compounding this:

+ Overwhelming buzzwords and complexity

+ Wrong intuition for HV systems

+ Unclear where to start

+ Capital requirements are high

+ Dangerous tech

What kind of tech stack did you use? I work on EV and EV-adjacent at $dayjob, I am very familiar with all of the concepts in your initial post.

Also, where did you get your battery(ies)?

Super interesting, message me on [e-mail] if you want.

Stack was leaf batteries, motor & inverter with our own gearbox modification (swapped direction), inverter with Openinverter.org Tesla model S A/C charger, Tesla DC/DC and then my own STM32 based control unit orchestrating all that.

Send me an email please, if you work in or with big auto I want to show you more of the app and get your opinion!
