Problems solved by technology
[0004] Disadvantages of the existing technology: because the protection of the battery pack of traditional portable devices only depends on the protection board inside the battery pack, when the protection mechanism of the protection board fails, for example, the HOLD function of the protection board fails, the battery pack cannot be protected , causing the battery pack to lose its protective device, thus making it impossible to guarantee the safety of the battery pack, reducing the reliability of portable devices and reducing the user experience

The invention discloses a portable device comprising a battery pack which is provided with N single batteries, N temperature sensors of which each corresponds to one single battery in the battery pack in arrangement and is used for detecting the temperature of the corresponding single battery, a charging and discharging manager which is used for charging and discharging the battery pack, and a controller which is used for judging whether or not the battery pack is abnormal according to the temperatures of the single batteries detected by the N temperature sensors and controlling the charging and discharging manager to stop charging or discharging the battery pack when judging that the battery pack is abnormal. According to the portable device of the invention, one temperature sensor is arranged for each single battery, so that the charging and discharging current and the charging and discharging state can be adjusted in real time according to the current temperature of the battery pack, the safety of battery pack charging and discharging is ensured when a protection mechanism of a protection board fails, the service life of the battery pack is prolonged, the reliability of the portable device is improved, and the user experience is improved. The invention further discloses a charging and discharging control method of the portable device.
Description
technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a portable device and a charging and discharging control method for the portable device. Background technique [0002] At present, with the continuous development and progress of science and technology, people are using various portable devices more and more widely, and the capacity density of battery packs of various portable devices is also getting higher and higher, causing people to charge the battery packs of portable devices And the requirements for discharge management are getting higher and higher, and the requirements for the protection and safety of battery packs of portable devices are also getting higher and higher, that is, the requirements for the reliability of portable devices are getting higher and higher. [0003] The protection of the battery pack of traditional portable devices relies on the protection board inside the battery pack. In the pr...
