Abstract

The invention discloses a battery protection board, comprising: a body; a voltage abrupt detecting circuit disposed on the body, wherein the voltage abrupt detecting circuit is configured to detect whether a battery voltage is abruptly changed and to output an abrupt signal when a sudden change occurs in the battery voltage; a battery protection unit, wherein the battery protection unit is connected to an output end of the voltage abrupt detecting circuit, the battery protection unit is configured to determine that the battery is damaged when receiving the abrupt signal and to protect the battery. The battery protection board of the invention can detect the battery abnormality in real time by detecting whether the battery voltage is abruptly changed, thereby timely protecting the battery,and avoiding the safety hazard caused by the battery abnormality. The invention also discloses a battery assembly with the above battery protection board and a terminal device having the same.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a battery protection board, a battery assembly and a terminal equipment with the battery assembly. Background technique [0002] The battery is the power source of the terminal equipment, and provides long-term stable power supply for mobile terminals 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 nickel-chromium and nickel-hydrogen batteries, it has no memory effect and is environmentally friend...
