Embodiment Construction

[0036] 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 part of the embodiments of the present invention, not all of them. 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.

[0037] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a battery in-place detection circuit, a battery in-place detection method and an intelligent wearing device. The battery in-place detection circuit comprises a discharge circuit, wherein the discharge circuit is configured to discharge a battery to be detected when a discharge control signal is received; a voltage division detection circuit configured to be started when a detection control signal is received so as to detect the voltage of the battery to be detected; a main controller configured to determine that the battery to be tested is in place when a first voltagedetection value before the battery to be tested discharges is less than a first preset voltage value; or determine that the battery to be tested is in place when the difference value between the firstvoltage detection value before the discharge of the battery to be detected and the second voltage detection value after the discharge of the battery to be detected is less than or equal to a first preset difference value, under the condition that the first voltage detection value before the discharge of the battery to be detected is greater than or equal to the first preset voltage value. The circuit achieves the in-place detection of the battery to be detected.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a battery presence detection circuit, method and smart wearable device. Background technique [0002] At present, in the production process of smart wearable devices, most of them need to assemble batteries to drive the smart wearable devices to work. Once the installation is missing, the smart wearable devices may not work properly. [0003] In a small number of charging chips for batteries, there is an in-position detection module. However, the cost of such charging chips is relatively high, and most of them do not feed back the detection results to the main controller of the smart wearable device. The main controller cannot confirm whether the battery is reign. Contents of the invention [0004] The main purpose of the present invention is to propose a battery presence detection circuit, method and smart wearable device, aiming at realizing battery presence dete...
