Description

technical field [0001] The invention relates to a mine-used nickel-hydrogen battery system, in particular to a battery system composed of a high-capacity nickel-hydrogen battery and a management system thereof. Background technique [0002] At present, mining equipment mainly uses lead-acid batteries and lithium batteries as power sources. Due to its lead pollution, lead-acid batteries have caused great harm to the environment, and its development is restricted by national policies. Lithium batteries have the advantages of small size and high energy, and are widely used in fields such as miner's lamps. However, due to the high requirements of the lithium battery production process, the current safety of a single lithium battery product is relatively high, and the group technology has not yet achieved breakthroughs, making it difficult to meet the safety and reliability requirements of large-capacity mining battery systems. Contents of the invention [0003] The invention...
