Lithium battery capacity grading formation temperature monitoring method and device

The invention provides a lithium battery capacity grading formation temperature monitoring method and device. The invention discloses a lithium battery capacity grading formation temperature monitoring method. The method comprises the following steps: acquiring a temperature acquisition instruction; starting a temperature sensor arranged on each lithium cell detection position of the capacity grading formation cabinet, and acquiring a temperature parameter on each lithium cell detection position through each temperature sensor; converting a temperature parameter on each lithium cell detection position into a detection position temperature signal in real time, wherein the detection position temperature signal comprises a temperature parameter, a position number and a process category; and a detection position temperature signal is wirelessly sent to the cabinet body MCU module. Wired cables are replaced by wireless transmission, so that dense cables are prevented from being arranged in the capacity grading for
