Embodiment Construction
[0071] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Apparently, the described embodiments are some, but 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.
[0072] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other e...

The invention relates to the technical field of batteries, in particular to a battery charging control circuit and electronic equipment. The battery charging control circuit and electronic equipment provided in this embodiment include: a switch circuit; a starting circuit, the starting circuit includes a first port and a second port, when the positive pole of the battery is electrically connected to the first port, and the negative pole of the battery is electrically connected to the second port , and when the switch circuit is in the cut-off state, the starting circuit and the battery form a first current loop, so that the starting circuit generates a starting signal, wherein the current flowing through the battery is the first current; the controller is used to delay the time according to the starting signal The switch circuit is controlled to be in a conduction state, so that the starting circuit, the switch circuit and the battery form a second current loop. The starting signal is generated by the first current loop generated by the normal connection of the battery, thereby delaying the opening of the second current loop to charge the battery, and avoiding the sparking phenomenon of the battery during charging.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery charging control circuit and electronic equipment. Background technique [0002] A battery refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate current, and is a device that converts chemical energy into electrical energy. Also, a battery as an energy source is an essential component for the operation of various electronic devices. For example, taking an aircraft such as a UAV as an example, the battery provides power for each system of the UAV to ensure the flight of the UAV and the aerial photography during the flight. [0003] In battery applications, a battery protection circuit is usually configured to provide protection functions such as over-discharge, over-charge, over-current, and over-temperature for the battery. There is also a relatively common problem in the use...
