Menene Takaddar PSE?

PSE (Tsarin Kayan Aikin Lantarki & Material) tsarin takaddun shaida ne na tilas a Japan. Ana kuma kiranta 'Compliance Inspection' wanda tsarin kasuwanci ne na dole don kayan lantarki. Takaddun shaida na PSE ya ƙunshi sassa biyu: EMC da amincin samfur kuma shi ma muhimmiyar ƙa'ida ce ta dokar aminci ta Japan don kayan lantarki.

▍ Takaddun Takaddun Shaida don batirin lithium

▍Me yasa MCM?

● Ƙwararrun wurare: MCM an sanye shi da ƙwararrun wurare wanda zai iya zama har zuwa dukkanin matakan gwajin PSE da kuma gudanar da gwaje-gwaje ciki har da gajeren da'ira na ciki da dai sauransu Yana ba mu damar samar da rahotanni daban-daban na gwaji a cikin tsarin JET, TUVRH, da MCM da dai sauransu. .

● Taimakon fasaha: MCM yana da ƙwararrun ƙwararrun injiniyoyin fasaha na 11 ƙwararrun ƙa'idodin gwajin PSE da ƙa'idodi, kuma yana iya ba da sabbin ƙa'idodi da labarai na PSE ga abokan ciniki a cikin daidaitaccen, cikakke da sauri.

● Sabis daban-daban: MCM na iya ba da rahotanni cikin Ingilishi ko Jafananci don biyan bukatun abokan ciniki. Ya zuwa yanzu, MCM ya kammala ayyukan PSE sama da 5000 don abokan ciniki gaba ɗaya.

Amintaccen tsarin ajiyar makamashi abin damuwa ne na kowa. A matsayin ɗaya daga cikin mahimman abubuwan tsarin ajiyar makamashi, amincin baturin lithium-ion yana da mahimmanci musamman.
