Problems solved by technology
[0003] However, due to the limitations of battery technology, the working time of portable computers is greatly limited in scenarios without a fixed power supply. For example, in the field, a battery can usually provide a working time of 2 to 3 hours; got a chicken rib
[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: when the portable computer is in battery mode, the user cannot control the power supply of the battery, and can only use the remaining battery power passively, so that the portable computer cannot operate in a sufficient state. working for a long time

The invention provides a method and a device for managing the service time of a cell, and a portable computer, wherein the method comprises the steps of: acquiring an upper limit threshold and a lower limit threshold of a discharging current of the cell; acquiring residual capacity of the cell; according to the residual capacity and the upper limit threshold and the lower limit threshold of the discharging current, calculating a service time range the residual capacity can provide; and resetting the value of the discharging current according to the service time selected by a user, wherein the service time is within the service time range. According to the technical proposal provided, the service power of the cell is self-controlled under a cell mode according to the residual capacity in the cell, so that the portable computer can operate for a reasonable period of time set by users.
Description
technical field [0001] The present invention relates to battery technology, in particular to a method, device and portable computer for managing battery life. Background technique [0002] Laptop computers have been widely used, especially in various application scenarios of mobile office, and people have been inseparable from the participation of laptop computers. [0003] However, due to the limitations of battery technology, the working time of portable computers is greatly limited in scenarios without a fixed power supply. For example, in the field, a battery can usually provide a working time of 2 to 3 hours; I got a chicken rib. [0004] In the process of implementing the present invention, the inventor found that there are at least the following problems in the prior art: when the portable computer is in battery mode, the user cannot control the power supply of the battery, and can only use the remaining battery power passively, resulting in the portable computer not...
