Abstract

The invention discloses a safe charge-discharge device and method of a handheld terminal. When a mobile phone is used, a charge-discharge detection unit is used for detecting a charge-discharge stateof the mobile phone, a battery is used for supplying power if charging is not performed, a battery temperature detection power supply unit is used for detecting a battery temperature when the batterysupplies power, when a battery temperature is higher than a set threshold, a warning unit displays that the battery temperature is excessively high, a user is reminded to enter a power supply mode ofa temporary energy storage unit, power consumption application can be closed, a charge-discharge control module temporarily cuts off power supply and closes a power consumption assembly of the system,power supply of the temporary energy storage unit is switched, when that the battery temperature is lower than the set threshold is detected, power supply of the battery is restored, the charge-discharge detection unit detects that the mobile phone enters a charging state, power supply of the battery is cut off, AC power supply is directly used, meanwhile, the battery is charged, after an external AC input is removed, the unit is automatically switched to power supply of the battery. By the safe charge-discharge device, the battery loss can be reduced, and a potential risk caused by heat generation of the battery is prevented.

Description

technical field [0001] The invention relates to the field of charging and discharging, in particular to a safe charging and discharging device and method for a handheld terminal. Background technique [0002] At present, handheld terminals have become an indispensable part of people's lives, especially the emergence of smart phones has greatly changed the way people live, entertain and even work. Whether it is a student, an office worker or a retired old man, everyone uses a mobile phone at different times. It can be said that a mobile phone is an item that is closely related to people's life and work. But most people don't know whether the charging and discharging of their mobile phones is safe, and why unsafe accidents occur when charging with a charger. In addition, the power consumption of mobile phones is one of the mobile phone performances that users are most concerned about. The realization of safe and intelligent charging and discharging methods for mobile phones h...
