MKBMS-HV Master

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 400V.

The MAXKGO 400V HV Master Board is a smart component that supports up to 500A Charging and discharging and works with VESC and Ennoid systems. This high-voltage input 450V to 12V step-down board is perfect for powering your devices, providing a safe and efficient power supply.

 MKBMS HV Master MiniBoard Features

• With charger voltage measurement, humidity sensor, isolated on-board 5V power supply for isolating CAN bus interface and USB Type-C
• 150V to 400V operation(Requires use with a 450V-12V step-down module)
• 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
