Description

Technical Field

[0001] This utility model relates to the field of circuit technology, specifically to a control circuit for a multifunctional V-port battery. Background Technology

[0002] A mobile power pack (MPP), also called a power bank or travel charger, is a portable charger that integrates power supply and charging functions, allowing you to charge mobile phones, tablets, and other electronic devices anytime, anywhere. It typically uses lithium-ion batteries as its energy storage unit, offering convenience and speed. V-port batteries are a type of mobile power pack specifically designed for the camera industry. They are called V-port batteries because their exterior features a V-shaped groove for easy attachment to some cameras as part of their power management circuitry.

[0003] V-mount batteries are lithium-ion batteries, a common piece of equipment in the videography industry and an essential product for videographers, almost ubiquitous in the field. V-mount batteries can meet the daily power needs of most film crews, can be directly attached to various types of cameras for easy portability, and can power peripheral electronic devices of the camera, eliminating the need to carry multiple different chargers each time, simplifying equipment preparation and improving crew efficiency. Internally, a V-mount battery typically consists of a rechargeable lithium-ion battery and a main control circuit board. The main control circuit board includes an output protection board for the battery area, temperature sensors and control elements at the battery end, and some voltage regulator components; the overall circuit design is very simple and clear.

[0004] NP-F batteries are a common type of lithium-ion battery, typically used in Sony digital cameras, camcorders, and other portable electronic devices. These batteries are known for their high capacity, low self-discharge rate, fast charging, high safety, durability, and long lifespan. The NP-F series offers different models, such as NP-F550, NP-F750, and NP-F970, each with slightly different capacities and sizes to suit various device needs.

[0005] While NP-F batteries have high capacity, their size limits their use. Although they are sufficient for daily or indoor shooting, when shooting outdoors, many spare NP-F batteries are usually needed to ensure the camera's battery life. Additionally, V-type batteries with multiple power interfaces are required to power the camera's peripheral electronic devices. This is not only troublesome to prepare and inconvenient to carry, but also causes battery anxiety and results in a less than ideal user experience. Utility Model Content
