LTC6812 15S Slave Features
- Aluminum alloy PCB, better heat dissipation effect
- Compatible with MKBMS and ENNOID BMS
- 5-15 cell level monitoring per board
- 1+8 temperature sensors per slave
- Self-powered by the monitored cells
- Ultra-low power consumption, sleep mode = 6uA
- Multiple slave boards can form an integrated board through the ISOSPI interface
- Daisychain Master ISOSPI communication
- 1.2mV accuracy, -40 to 120C operation
- 33 ohm balance resistors (0.125A capacity) on all channels
- Scalable and isolated 1000VDC+
- Molex SL horizontal connectors for balance and temperature
Pack Configuration Examples
- MKBMS monitoring 25S pack: 2 x LTC6812-15S: 13S + 12S (Two slaves partially loaded)
- MKBMS monitoring 27S pack: 2 x LTC6812-15S: 13S + 14S (Two slaves partially loaded)
- MKBMS monitoring 29S pack: 2 x LTC6812-15S: 14S + 15S (Two slaves partially loaded)
- For uneven cell count in series, 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
