Problems solved by technology
The earliest batteries used in mobile terminals were nickel-chromium batteries and nickel-metal hydride batteries. However, with the increase of mobile terminal screens and enhanced functions, the capacity of nickel-chromium batteries and nickel-hydrogen batteries has been unable to meet the energy demand, while lithium-ion batteries Because it has many advantages, such as high energy density, it can be made lighter and has a larger capacity, faster charging and discharging, and compared with nickel-chromium and nickel-hydrogen batteries, it has no memory effect and is environmentally friendly. The damage is also minimal, so it gradually replaces the traditional nickel-chromium batteries and nickel-metal hydride batteries
[0003] Although the emergence of lithium-ion batteries has effectively solved the problem of battery capacity, there are also safety issues. For example, when the lithium-ion battery is damaged and causes a short circuit, heat will be generated inside the battery cell. Batteries may catch fire or explode, so battery safety monitoring is required to prevent accidents

A battery safety monitoring method, a battery safety monitoring system, a terminal device, and an adapter, wherein the battery safety monitoring method includes the following steps: when the terminal device (10) is fully charged and remains connected to the adapter (20), if the If the terminal device (10) is in a low power consumption state, then obtain the recharging situation (S1) of the terminal device (10); judge whether the battery of the terminal device (10) is abnormal according to the recharging situation of the terminal device (10) ( S2). The battery safety monitoring method judges whether there is an abnormality in the battery by monitoring the recharging situation of the battery after charging, so as to remind and send for repair in time, thereby avoiding potential safety hazards caused by the abnormality of the battery.
Description
technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a battery safety monitoring method, a battery safety monitoring system, a terminal equipment with the battery safety monitoring system, and an adapter with the battery safety monitoring system. Background technique [0002] The battery is the power source of the terminal equipment, providing long-term stable power supply for the terminal equipment such as mobile phones. The earliest batteries used in mobile terminals were nickel-chromium batteries and nickel-metal hydride batteries. However, with the increase of mobile terminal screens and enhanced functions, the capacity of nickel-chromium batteries and nickel-hydrogen batteries has been unable to meet the energy demand, while lithium-ion batteries Because it has many advantages, such as high energy density, it can be made lighter and has a larger capacity, faster charging and discharging, and compared with ni...
