[FSE] Odpoveď: Prague CTU_Rule 7.25 BMS

[Dominik Macko]

Zdravím,
Posielam mailovú konverzáciu, ktorú som viedol s porotou pre pravidlá 
(FSE-Rules na FormulaStudent.de).
Ak sa vám to nechce čítať, tak len zhrniem, že sme sa dostali k 
riešeniu. BMS bude musieť vypínať trakčný systém priamo, ako som to 
zamýšľal a ako je to znázornené v schéme zapojenia. Možnosť, že BMS by 
posielalo signály microcontrolleru a ten by následne vypínal trakčný 
systém sme zamietli.

S pozdravom

Dominik
