Description

technical field [0001] The invention relates to the technical field of solar charging and wireless charging, in particular to a heterogeneous multi-mode intelligent power management system and method applied to unmanned underwater vehicles. Background technique [0002] As an important branch of unmanned carrier platform, unmanned underwater vehicle plays an important role in military and civilian fields. In the past 30 years, many maritime powers have manufactured more than 9,000 unmanned underwater vehicles to complete various underwater tasks. These unmanned underwater vehicles have demonstrated their superiority in rescue, search, scientific research and other fields. In 2016, my country's first portable underwater unmanned autonomous vehicle was unveiled at the Zhuhai Air Show. The unmanned underwater autonomous vehicle adopts a portable design, which is easy and fast to deploy and recover; simple operation and short learning period; modular design and strong scalabili...

Problems solved by technology

At present, most unmanned underwater vehicles still use wired charging to charge lithium battery packs. Due to the characteristics of unmanned underwater vehicles working underwater, this wired charging method will destroy the airtightness of underwater vehicles. , at the same time, the aircraft needs to be recovered when charging, which increases the operating cost

In addition to wired charging, solar charging is also used in unmanned underwater vehicles. my country is rich in solar energy, and nearly 70% of the land area has more than 2,000 hours of sunshine, but solar charging alone cannot be used in rainy and other weather conditions. Use, unable to make UUV work 24 / 7

[0004] At the same time, the current lithium battery pack used by unmanned underwater vehicles is mainly composed of multiple single lithium batteries connected in parallel. At the same time, it inevitably introduces dangers. As long as one of the multiple parallel-connected single lithium batteries fails, the entire lithium battery pack will be unusable, thereby affecting the work of the unmanned underwater vehicle. The single lithium battery in the lithium battery pack requires the same specification parameters, which virtually increases the battery cost

In addition, the output voltage of lithium battery packs currently used by unmanned underwater vehicles is fixed, and can only be used in specific application scenarios. Faced with different application scenarios and different loads, the current lithium battery packs and their management systems are not competent.
