▍He aha MCM?

● Tautoko ngawari mai i te tohu me te hangarau:I te mea ko te taiwhanga whakamatautau kaitaunaki o TUVRH me ITS i te Tiwhikete o Amerika ki te Raki, ka taea e MCM te mahi i nga momo whakamatautau katoa me te whakarato ratonga pai ake ma te whakawhiti hangarau kanohi ki te kanohi.

● Tautoko uaua mai i te hangarau:Ko te MCM he taputapu whakamatautau katoa mo nga pākahiko o nga kaupapa nui-rahi, iti-rahi me te tino tika (ara te motuka hiko hiko, te kaha rokiroki, me nga hua mamati hiko), ka taea te whakarato i nga ratonga whakamatautau pākahiko me nga ratonga tiwhikete i Amerika Te Tai Tokerau, e kapi ana i nga paerewa. UL2580, UL1973, UL2271, UL1642, UL2054 me etahi atu.

UL 1973:2022i taia i te 25 o Pepuere. I ahu mai tenei putanga i runga i nga tauira whakaaro e rua i tukuna i te marama o Haratua me Oketopa o te tau 2021. Ko te paerewa kua whakarereketia te whakawhānui ake i tona awhe, tae atu ki te punaha hiko kaiawhina waka (hei tauira, te whakamarama me te whakawhitiwhiti korero).
Tāpirihia te 7.7 Transformer: ko te kaihurihuri mo te punaha pākahiko ka whakamanahia i raro i te UL 1562 me te UL 1310 me nga paerewa e tika ana. Ka taea te tiwhikete ngaohiko iti i raro i te 26.6.
Whakahoutanga 7.9: Porowhita Tiaki me te Mana Whakahaere: ka tukuna e te punaha pākahiko he whakawhiti, he pakaru ranei, ko te iti rawa e hiahiatia kia 60V hei utu mo te 50V. He whakaritenga taapiri mo te ako mo te whakakorikori.
Whakahōu 7.12 Pūtau (pāhiko me te pūnga hiko hiko): Mo te rechargeable Li-ion pūtau, te whakamātautau i raro i te tāpiritanga E te hiahiatia, kahore whakaaro UL 1642. Me hoki pūtau ki te tātari ki te whakatutuki i te tono o te hoahoa haumaru, rite rauemi me te tūnga o te insulator, te kapi o te anode me te cathode, etc.
Tāpirihia te 16 Te Utu Utu Teitei: Aromātaitia te whakamarutanga o te whakamarumaru o te punaha pākahiko me te nui atu o te utu o naianei. Me whakamatautau i roto i te 120% o te utu utu nui.
Tāpirihia te 17 Whakamātautau Porowhita Poto: Whakahaerehia he whakamatautau ara iahiko poto mo nga waahanga pākahiko e hiahia ana kia whakauruhia, kia whakarereke ranei.
