AI Technical Summary

Problems solved by technology

However, in the lithium battery protection measures of this technology, an emergency processing module, that is, a multi-way sub-switch, is used to protect the lithium battery from sub-circuit shutdown. The shutdown of a single lithium battery will cause insufficient power in the power supply system and affect the normal operation of the connected equipment. Use, single protection measures, imperfect solutions to battery problems
