MKBMS is based on the modular BMS of LTC68XX and STM32 MCU, and is connected to one or more slave boards and integrated integrated boards of different sizes through the ISOSPI interface. The modular BMS can be configured for various applications with battery voltages within 150V. MKBMS Master Board ( MKBMS-LV Master Mini ) Features: With charger voltage measurement, humidity sensor, isolated on-board 5V power supply for isolating CAN bus interface and USB Type-C 17V to 150V operation Voltages measurements for load & battery pack Bi-directional current monitoring (up to 2500A pulsed, 500A continuous) Isolated charger detection circuit Isolated CAN bus interface Daisychain Master/Slave ISOSPI communication Single PCB pattern for bolt-on contactor It can internal power supply or external power supply voltage is 12V Integrated predischarge circuit USB & serial interface for configuring and firmware upgrades with the ENNOID-BMS-Tool OLED display output ON/OFF toggle switch input SWD burn debugging or update firmware interface   MKBMS Slave Board Features: MKBMS slave board is made of aluminum base plate, which has better heat dissipation effect. Scalable & isolated 1000VDC+ Compatible with MKBMS Master boards From 5 to 18 cell levels monitoring per board Daisychain Master/Slave ISOSPI communication Parameters fully programmable through an easy to use graphical user interface 33 ohm balance resistors (0.125A capacity) on all channels Self powered by monitored cells 1.2mV accuracy, -40 to 120C operation Extra low power consumption (Sleep mode = 6uA) Molex SL horizontal connectors for balance & temperature. (Comes with male, female + crimps)       Variant:      LTC6811 : Up to 12 series-connected battery cells & 1+4 temperature sensors* per slave      LTC6812 : Up to 15 series-connected battery cells & 1+8 temperature sensors* per slave      LTC6813 : Up to 18 series-connected battery cells & 1+8 temperature sensors* per slave      *The first temperature channel is used by slave board itself. The following 4 or 8 temperature sensors are not in the package lists but means an interface to connect 4 temp sensors at most or to connect 8 temp sensors at most. *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 battery management system implements the following functions: 1. Current and voltage protection: protect the battery pack from overcharge and overdischarge, 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 MKBMS can be roughly divided into three aspects: automobile, industry, and consumption: 1.  Electric vehicles;2.  Electric patrol car;3.  Scenic sightseeing car;4.  Handling robots;5.  Automatic forklift;6.  Electric bicycles;7.  Electric skateboard;8.  Electric tools;9.  Consumer robots, etc. Video: Shipping list: MKBMS-LV Master Mini Package 1X   PCBA board MKBMS-LV Master Mini V1.4 2X   GH1.25 single head 2P line 1X   GH1.25 double head 2P same direction line 3X   HY2.0 single head 2P line 2X   GH1.25 single head 5P line 1X   GH1.25-5P to Dupont line 1X   USB cable type-C data cable 1X   2.0MM jumper cap 1X   1.3 inch OLED display LCD screen module 1X  12MM 3-6V button switch   LTC6811-12S Package 1X   PCBA board LTC6811-12W-AL V1.2 slave board 1X  GH1.25 double head 2P red-black line (for master board)   1X  GH1.25 double head 2P black-white line (for slave board) 1X   HY2.0 single head 5P line 1X   HY2.0 single head 13P line 4X   Nylon column 4X   Nylon nut     LTC6813-18S  Package 1X PCBA board LTC6813-18S V1.4 slave board 1X  GH1.25 double head 2P red-black line (for master board)   1X  GH1.25 double head 2P black-white line (for slave board) 1X HY2.0 single head 6P line 1X HY2.0 single head 13P line 1X HY2.0 single head 16P line 4X nylon column 4X nylon nut   LTC6812-15S  Package—— 1X   PCBA board LTC6812-15S slave board 1X  GH1.25 double head 2P red-black line (for master board)   1X  GH1.25 double head 2P black-white line (for slave board) 2X   HY2.0 single head 8P line 1X   HY2.0 single head 16P line 4X   Nylon column 4X   Nylon nut    MKBMS hardware design file: LTC6811-12W_V1.2 MKBMS-LV_Master_Mini_V1.4
