The invention provides a charging reminding device for an external battery of an electronic device, which is arranged in the external battery and includes a measuring device for measuring the instant capacity of the external battery. The charging reminding device also includes: a detection module, which detects When the external battery is removed, it outputs a removal signal; the timing module starts timing after receiving the removal signal, and outputs a timing signal; the capacity comparison module, after receiving the removal signal, regularly or irregularly compares the instant capacity with the preset Compared with the preset low-capacity threshold, if the instant capacity is lower than the low-capacity threshold, the first alarm signal is output; the time comparison module is used to receive the timing signal, and compare the timing signal with the preset early warning time, if the timing signal If the warning time is exceeded, the second alarm signal is output; the alarm module is used for alarming after receiving the first alarm signal or the second alarm signal. The invention can detect the removal time and the instant power of the external battery, and effectively remind the user to charge in time.
Description
technical field [0001] The invention relates to a charging reminding device and method for an external battery of an electronic device. Background technique [0002] The external battery of electronic equipment, such as the external battery of a notebook computer, will cause the battery to be over-discharged and cannot be charged if it is removed due to its own power consumption and stored for a long time without charging, resulting in damage to the battery. The existing solution is mainly to inform the user to regularly charge the removed battery pack through the product manual, and the charging cycle is at least once a month. However, because the user does not read the instruction manual or forgets this reminder, the user usually does not charge the battery regularly and leaves the disassembled battery pack for a long time, which causes the battery to be over-discharged and cannot be recharged, resulting in irreversible damage to the battery.
