Description

Technical Field

[0001] The utility model belongs to the technical field of power supply devices, and in particular relates to a large-capacity driving battery pack for an underwater robot. Background Art

[0002] With the rapid development of science and technology, underwater robot technology is changing with each passing day. In this process, large-capacity drive battery packs, as the "energy heart" of underwater robots, play a vital role. The challenges of the underwater environment to batteries mainly come from high voltage and low temperature. The performance of traditional battery packs drops significantly under high pressure and low temperature conditions, and they cannot provide stable and lasting energy support for underwater robots. In addition, underwater robots require high-power drives when performing tasks, which requires battery packs to have higher energy density and faster charging speeds. Traditional battery packs can no longer meet the high-performance requirements of modern underwater robots, which prompted us to develop large-capacity drive battery packs designed specifically for underwater robots.
