The invention discloses a battery management controller and a battery management method.The battery management controller comprises a power supply module, a pressure sensor chip, an SBC assembly and a microprocessor, and the power supply module is connected with the sensor chip and the SBC assembly and used for supplying power to the sensor chip and the SBC assembly; the pressure sensor chip is arranged on a main control board of the battery management controller and used for detecting a pressure signal in a battery pack, when the pressure sensor chip detects that the pressure signal is abnormal in a sleep mode, the SBC assembly is awakened, the SBC assembly supplies power to the microprocessor to awaken the microprocessor, and the microprocessor is connected with the battery management controller. And the microprocessor obtains a historical pressure signal detected by the pressure sensor chip and judges whether the battery pack has a thermal runaway risk or not according to the historical pressure signal. According to the battery management controller provided by the invention, the pressure sensor chip is integrated on the main control board of the battery management controller, so that the cost is low, installation is not needed, the power consumption is small, and wiring harnesses are not needed.
