The invention provides a battery pack intelligent sensing controller and application, and the controller comprises a data collection unit which obtains a plurality of parameters of a battery pack; the communication and processing unit gathers a plurality of parameters for processing operation, and sends the parameters to a communication network to be used by an external battery management system main controller or a power domain controller; the communication and processing unit receives an instruction of the battery management system main controller or the power domain controller; the high-voltage relay driving unit controls the on and off of an external high-voltage relay, enables or stops the charging and discharging of the battery pack, and carries out fault diagnosis and safety protection; the power supply unit supplies low-voltage power to the data acquisition unit, the communication and processing unit and the high-voltage relay driving unit; the communication and power supply isolation unit isolates external low-voltage power supply and communication. The intelligent sensing controller is used for controlling the relay, the functions of collecting and monitoring parameters such as current and voltage and the control function of the relay are integrated, and when the intelligent sensing controller breaks down, a whole vehicle system is not affected.
