▎ 摘　　要

NOVELTY - The equipment has a power supply monitoring module connected with a graphene-lithium battery. A DC-DC converter and an inverter are connected with each other for collecting a working state signal to output a state signal of the graphene lithium battery. The controller is connected with a power supply detecting module for receiving the working state signal and the output state signal when working state signal range is more than a preset safe value. The graphene-lithium battery is controlled to stop charging and discharging processes. The controller is connected with a switch for controlling an opening and closing state of the switch. USE - Graphene emergency power supply equipment. ADVANTAGE - The equipment has high power service life and use safety and stability output and prolong discharge time so as to convenient to use. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a graphene emergency power supply equipment. '(Drawing includes non-English language text)'
