In　order　to　avoid　the　frequent　charging　of　e-bike　in　the　room　to　cause　fires　and　cause　serious　fire　hazards,　this　paper　proposes　a　recognition　algorithm　for　the　charging　current　of　e-bikes　based　on　variational　mode　decomposition.　Firstly,　the　current　in　the　power　network　is　decomposed　in　a　variational　mode,　and　then　compared　with　the　mode　of　the　e-bike　sample,　and　finally　the　analysis　results　determine　whether　there　is　an　e-bike　charging　load　in　the　current　system.　Experiments　show　that　when　e-bikes　are　used　together　with　eight　common　household　electrical　devices　such　as　computers,　air　conditioners,　notebooks　and　refrigerators,　the　algorithm　in　this　paper　can　accurately　identify　e-bikes.　The　algorithm　of　this　paper　provides　a　reference　for　the　detection　of　residential　electricity　risk.　©　2022　IET　Conference　Proceedings.　All　rights　reserved.
