What is a Battery Management System? 5 Minute Intro

[janosch]

A high level overview of a Lithium Ion Battery Management System in a five minute video.

If you are here on openinverter you already know what this is all about:
Not using a BMS puts capital and lives at risk. Using one, allows you to tame the power in Lithium batteries and drive electric cars fast on the motorway.

This is the first in a series of videos in which I outline the basic concepts underpinning the energy transition, including electric cars, solar, home storage, wind turbines, electric bicycles or even hydro.

This is my knowledge from building 3 custom electric cars and driving them 20k miles condensed into short and easily digestible video.

A Battery Management System

1. Measures data points for lithium cells and reports findings to other systems
2. Carries out calculations for State of Health or State of Charge of the cells
3. Battery Balancing! (separate video coming up)
4. Isolation Resistance Monitoring

I threw in some misconceptions at the end.
Let me know what you think!
