How it works

96s CATL prismatic cell arrangement. SAIC/MG BMS communicates on dedicated 500 kbps CAN bus. Battery-Emulator handles contactor precharge sequencing and state-of-charge tracking.

Notes

CATL NMC prismatic cells configured as 96s. Shared with Roewe Ei5 and MG Marvel R. Operating voltage window 310.0–404.0 V*. Standard 400 V class architecture matches common solar hybrid inverters (Solis, Deye, SolaX, GoodWe).

Red flag

Internal contactors lock out permanently if BMS records crash data or sustained high-voltage isolation fault below 100 kΩ.
