The invention discloses an active thermal safety monitoring device and method for a power battery. The device comprises a power supply module, an enabling awakening module, a sensor module, an MCU control module, a response output module and a communication module. The power supply module is connected with the sensor module, the MCU control module, the response output module and the communicationmodule; the enabling awakening module is connected with the MCU control module; an enable signal reflecting the running mode of the whole vehicle can be sent to the MCU control module; the sensor module is connected with the MCU control module; a detected signal reflecting thermal runaway is sent to the MCU control module; the MCU control module is connected with the response output module and canoutput a thermal safety execution module awakening signal and a signal reflecting that the MCU control module is in a normal working mode through the response output module, and the MCU control module is connected with the communication module and can send a signal reflecting thermal runaway through the communication module. Whether thermal runaway happens to the power battery or not can be monitored, and the safety of the power battery is improved.
