The invention provides a battery management controller and a communication method for the battery management controller. The communication method comprises the steps that a high-voltage board communicates with a domain controller through a first daisy chain; the sampling plate communicates with the domain controller through a second daisy chain; the high-voltage relay communicates with the domain controller in a PIN mode; wherein the first daisy chain and the second daisy chain are mutually independent, and an instruction signal for controlling the sampling board is directly sent by the domain controller; an instruction signal for controlling the high-voltage board is directly sent by the domain controller; and a driving instruction for controlling the high-voltage relay is directly sent by the domain controller.

    本发明提供了电池管理控制器及用于电池管理控制器的通讯方法。所述通讯方法包括:高压板通过第一菊花链与域控制器通信;采样板通过第二菊花链与所述域控制器通信;以及高压继电器通过PIN方式与所述域控制器通信;其中,所述第一菊花链与所述第二菊花链互相独立,控制所述采样板的指令信号由所述域控制器直接发送;控制所述高压板的指令信号由所述域控制器直接发送;控制所述高压继电器的驱动指令由所述域控制器直接发送。
