Protezione batteria BMS Scheda master LV 30 V-150 V

MKBMS is based on the modular BMS of LTC68XX and STM32 MCU, and is connected to one or more slave boards and integrated boards of different sizes through the ISOSPI interface.

The modular BMS can be configured for various applications with battery voltages within 150V.

• MKBMS monitoring 30S pack: 2 x LTC6812-15S: 15S + 15S (Optimal)
• MKBMS monitoring 30S pack: 2 x LTC6813-18S: 15S + 15S (Two slaves partially loaded)
• MKBMS monitoring 35S pack: 3 xLTC6811-12S: 12S + 12S + 11S (Good)
• MKBMS monitoring 35S pack: 3 x LTC6812-15S: 12S + 12S + 11S (Three slaves partially loaded)
• MKBMS monitoring 35S pack: 2 x LTC6813-18S: 18S + 17S (Optimal choice)
• Per conteggio irregolare delle cellule in serie, only the last slave board in the daisy-chained loop should have one cell less connected than the other slaves. Ex: 39S = 10S + 10S + 10S + 9S
