General knowledge
The accumulator container has mainly two important jobs: keeping the electricity from the cells inside and protect the people outside.
The huge problem with electricity is, that you neither can’t see, nor hear or smell it. Once you’ve have touched it, life might be over for you.
Neben diesen anforderungen muss der Container auch in einer reasonable zeit ins Auto zu setzen und wieder daraus zu entfernen sein. Das ist notwendig für die accumulator inspection und das Laden und auch Entladen des Akkus.
Für das material des containers müssen laut den rules aluminium oder stahl verwendet werden, alternative materialien sind zulässig, wenn in der Berechnung eine Äquivalenz der eigenschaften vorgewiesen werden kann.
Große herausforderung für die konstruktion und die berechnung des containers ist, container ist, dass er als anforderung eine beschleunigung von 40g in längs- und querrichtung, sowie 20g in vertikal-richtung aushalten können muss.
der Accu container ist ziemlich geil. Ansonsten ist nicht viel dazu zu sagen. Und der Konstrukteur erst ist einfach die geilste Socke vom Planeten.

Notes and Hints taken from “Electronics/Software”
If something is missing/ is wrong or not understandable, please provide feedback to us. The reference design is still under development and might be not yet complete.
Take care of important details during the commissioning phase and understand the behavior of the system. Get familiar with the main ideas and have fun by working with this design.
Please check the newest rules rules and bring your accumulator to the newest accquired state.
Therefore, read the capter Battery Management System - Master (BMS-Master) at first and have a look at the following chapter General knowledge - STM32.
General knowledge - STM32
Since there are already different documentations and youtube videos for the STM32 development available, here are only some hints which documentation could be helpful.

Hint
The understanding of step 1 and step 2 are neccessary for the Battery Management software!
