Example methods and apparatuses for detecting lithium plating and obtaining a polarization proportion are provided. One example method includes obtaining an open-circuit voltage of a rechargeable battery and a negative electrode open-circuit voltage of the rechargeable battery based on a state of charge of the rechargeable battery. A negative electrode polarization voltage of the rechargeable battery is obtained based on the open-circuit voltage, a terminal voltage of the rechargeable battery, and a polarization proportion of the rechargeable battery. A negative electrode voltage of the rechargeable battery is obtained based on the negative electrode open-circuit voltage and the negative electrode polarization voltage. It is determined, based on the negative electrode voltage, whether lithium plating occurs in the rechargeable battery.
