摘要
An interface circuit for cascade battery management and an interface circuit for series battery management are provided. The interface circuit for cascade battery management comprises a master microcontroller, a slave microcontroller, a receiving opto-coupler, and transmitting opto-coupler. The master microcontroller is coupled to a first battery block. The slave microcontroller is coupled to a second battery block. The receiving opto-coupler has an input terminal coupled to an output terminal of the master microcontroller, and the receiving opto-coupler has an output terminal coupled to an input terminal of the slave microcontroller. The transmitting opto-coupler has an input terminal coupled to an output terminal of the slave microcontroller, and the transmitting opto-coupler has an output terminal coupled to an input terminal of the master microcontroller. The master microcontroller communicates with the slave microcontroller using the pulse-width-modulation (PWM) through the transmitting opto-coupler and the receiving opto-coupler.
