Support battery: support almost all lithium batteries such as lithium ion battery, lithium polymer battery, lithium phosphate battery, etc.

 

LTC6212 15S Slave Board Features ——

1. Aluminum alloy PCB, better heat dissipation effect.

2. Compatible with MKBMS and ENNOID BMS.

3. From 5-15 cells level monitoring per board.

4. 1+8 temperature sensors per slave.

5. Self-powered by the monitored cells.

6.Ultra-low power consumption, sleep mode=6uA.

7. It can be connected to multiple slave boards to form an integrated board through the ISOSPI interface

8. Daisychain Master / Slave ISOSPI communication

9. 1.2mV accuracy, -40 to 120C operation

10. 33 ohm balance resistors (0.125A capacity) on all channels

11. Scalable & isolated 1000VDC+

12. Molex SL horizontal connectors for balance & temperature. (Comes with male, female + crimps)

 

*The first temperature channel is used by slave board itself.

The following 8 temperature sensors are not in the package lists

but means an interface to connect 8 temp sensors at most.

 

 

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

 

 

MKBMS Functions:

  1. Current and voltage protection: protect the battery pack from overcharge and over discharge, thereby extending the cycle life.
  2. Battery health monitoring: monitor the internal resistance of a single battery and the monitoring capacity of the battery pack.
  3. Thermal management: Overheating and under-temperature protection.
  4. Support batteries: Li-Ion, Li-Polymer, Li-Phosphate
  5. Intelligent battery balance: passive balance 
  6. Field programmable
  7. Current limit calculation
  8. Fully programmable CANBUS interface, programmable structure of all CAN messages
  9. Drift state of charge
  10. Reliability, speed and accuracy
  11. Integration with other devices
  12. Multiple BMS units connected in series
  13. Current sensor support
  14. Isolation from fault detection
  15. Automotive grade design, automotive grade locking connector
  16. Software for data logging and programming
