(a)UX1, UX2, UX3 and UX4 are linear photo.

(b)CNX6, CNX7, CNX8 and CNX11 connect the NTC to the external battery cabinet.

(c)System MCU detects the external battery cabinet temperature via EXTB_TEMP1 (104) for battery cabinet 1, EXTB_TEMP2 (106) for battery cabinet 2, EXTB_TEMP3 (111) for battery cabinet 3, and EXTB_TEMP4 (112) for battery cabinet 4.
