Electric Skateboard Battery Management System - MKBMS LV Master Mini PCBA Board

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 is developed based on the open source materials of DieBieMS and ENNOID BMS. Currently MKBMS is compatible with ENNOID firmware. Here, a special thanks to the developers of open source BMS materials.

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
• 30V 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 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.
