  "textContent": "A method for estimating a power limit of a battery pack is disclosed, including: obtaining an actual minimum cell voltage of an electrical core with a minimum voltage in the battery pack (S110); obtaining a static discharge power limit of the battery pack (S120); calculating, based on the actual minimum cell voltage, an estimated discharge voltage of the electrical core with the minimum voltage for use when the battery pack is discharged based on the static discharge power limit (S130); determining whether the estimated discharge voltage falls between a discharge voltage control threshold of the electrical core with the minimum voltage and an undervoltage threshold of the electrical core with the minimum voltage, where the discharge voltage control threshold is greater than the undervoltage threshold (S140); and determining a target discharge power limit of the battery pack through a discharge interpolation algorithm based on the estimated discharge voltage, the static discharge power limit, the discharge voltage control threshold, the undervoltage threshold, and a minimum power limit of an integrated vehicle when the estimated discharge voltage falls between the discharge voltage control threshold and the undervoltage threshold (S150). This application implements power control during operation of a vehicle and avoids undervoltage or overvoltage.",
