[0003] The above ranges are based on the general voltage range, but for batteries from different manufacturers, the discharge voltage curves are different. For example, the 0.9V discharge of Nanfu battery is close to the end, and the 1.2V discharge of Jinli disposable lithium battery is close to the end. If the low battery alarm voltage Setting it to 1V will cause the product to alarm in advance when the battery is not used up, or to cut off the power before the alarm, which cannot make full use of the battery, and may even affect the use of the product if it is serious

Embodiment Construction
[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0054] see Figure 1-6 As shown, the present invention is a disposable battery power detection method, comprising the following steps:
[0055] SS00: Establish a disposable battery discharge curve database and implant it into the microcontroller program;
[0056] SS01: Power on the device using a disposable battery to make the battery under test work. Since the voltage and time are not recorded when the device is turned off, the product does not consume power, so ...

The invention discloses a disposable battery power detection method and relates to the technical field of battery power detection. The invention includes establishing a database of discharge voltage curves, detecting changes in battery voltage over time during use, selecting corresponding battery curves, giving power prompts and alarm prompts, and simultaneously recording the detected new battery discharge voltage curves, removing duplicate judgments and adding The battery discharge curve database is used as a reference for judging the power of the new battery next time. The database of the present invention stores a number of disposable battery discharge voltage curves. By comparing the collected data with the discharge voltage curves in the database and selecting the closest curve, the remaining power of the battery can be accurately calculated, and the user can be reminded to replace the battery in time. Disposable batteries of different brands or manufacturers can make full use of the battery power and avoid the situation of power off in advance without prompting, so as to ensure the continuous and effective use of the product.
Description
technical field [0001] The invention belongs to the technical field of battery power detection, in particular to a method for detecting the power of a disposable battery. Background technique [0002] At present, low-power electronic products on the market are using disposable batteries, which are lower in cost and can be discarded at any time. There is no need for battery charging time, and the product can be used immediately when the battery is out of power, and it does not involve connecting to the grid for charging, so the product is safer. . It is particularly important to judge the power of products using primary batteries to ensure continuous and stable work of the product; currently, electronic products on the market display the power, and compare the detected voltage with a single preset voltage segment value to obtain a segment or percentage. Display, or when the preset low battery range is reached, a low battery alarm prompt will be given. [0003] The above ran...
