摘要： The present invention provides a battery pack, comprising a first cell and a second cell connected in series, the first cell having a current cut-off device and having a first failure voltage, the current cut-off device being configured to be able to break a circuit in response to a voltage value of the first cell reaching or exceeding the first failure voltage, and the second cell having no current cut-off device. According to the technical solution of the present invention, the battery pack may use a soft pack battery as the second cell, having advantages such as high energy density, low impedance, high discharge power, a low rate of temperature rise during high-rate discharge, and flexibility in dimensions. At the same time, a cylindrical battery may be used as the first cell; this has a built-in current cut-off device, so can mitigate the problem of soft pack batteries being susceptible to overcharging and consequent thermal runaway, thus improving safety.

摘要： The present invention relates to an adapter, configured to be adaptively connected to an electrical apparatus and a battery pack. The adapter includes a housing, a first locking portion, and a second locking portion. The first locking portion is movable relative to the housing between a first locking position at which the first locking portion is locked to the electrical apparatus and a first unlocking position at which the first locking portion is unlocked from the electrical apparatus, and the second locking portion is movable relative to the housing between a second locking position at which the second locking portion is locked to the battery pack and a second unlocking position at which the second locking portion is unlocked from the battery pack. In this way, the electrical apparatus interface and the battery pack interface can be flat, the size can be compact, thereby being convenient for a user to carry and use. The present invention further provides an electrical apparatus system including an electrical apparatus, a battery pack, and the adapter described above, and provides an operating method for an electrical apparatus system.
