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