Kutshanje IKomishoni yoMbane yeHlabathi ye-EE ivume, yakhulula kwaye yarhoxisa izisombululo ezininzi ze-CTL kwiibhetri, ezibandakanya ubukhulu becala umgangatho wesiqinisekiso sebhetri ephathwayo IEC 62133-2, isiqinisekiso sogcino lwebhetri yomgangatho we-IEC 62619 kunye ne-IEC 63056. Oku kulandelayo ngumxholo othile wesisombululo:

IEC 62133: 2017, IEC 62133: 2017 +AMD1:2021: cima ibhetri 60Vdc imfuneko yamandla ombane

NgoDisemba 2022, i-CTL yakhupha isigqibo sokuba amandla ombane eemveliso zebhetri ayinakudlula i-60Vdc. Akukho nkcazo ecacileyo malunga nomda wombane kwi-IEC 62133-2, kodwa ibhekisela kumgangatho we-IEC 61960-3.

Isizathu sokuba esi sigqibo sirhoxiswe yi-CTL kukuba “umda wamandla ombane ongaphezulu we-60Vdc uya kuthintela ezinye iimveliso zomzi-mveliso ekubeni zingene kolu vavanyo luqhelekileyo, olufana nezixhobo zombane, njl.njl.

IEC 62133: 2017, IEC 62133: 2017 +AMD1:2021: cima imfuno yokusebenza yobushushu bokutshaja

Ngokufanayo, kwisisombululo sethutyana esikhutshwe ngoDisemba wonyaka ophelileyo, kwacetywayo ukuba xa uhlawuliswa ngendlela yeSiqendu 7.1.2 (efuna ukutshaja kwimida yokushisa ephezulu kunye nesezantsi), nangona kwiSihlomelo A.4 somgangatho sichaza ukuba xa ubushushu obuphezulu bokutshaja bungekho 10℃/45℃, ubushushu obulindelekileyo bokutshaja kufuneka bube +5℃ kwaye bungaphantsi. ukutshaja ubushushu kufuneka -5℃. Nangona kunjalo, ngexesha lovavanyo lwangempela, ukusebenza kwe-+/-5 ° C kunokushiywa kwaye ukutshaja kunokwenziwa ngokweqondo lokushisa eliqhelekileyo eliphezulu / elisezantsi lokutshaja.

Esi sigqibo siphunyezwe kwintlanganiso yocweyo yeCTL yalo nyaka.

I-IEC 62619: 2017: sebenzisa i-BMS yomntu wesithathu kuvavanyo lokhuseleko ekusebenzeni kwebhetri

Esi sigqibo simalunga novavanyo lokhuseleko lwenkqubo ye-BMS yebhetri.

Ngoku uninzi lwabavelisi beebhetri bathenga i-BMS kumaqela esithathu, nto leyo enokubangela ukuba umenzi webhetri angakwazi ukuqonda uyilo oluneenkcukacha lwe-BMS. Xa i-arhente yokuvavanya iqhuba uvavanyo lokhuseleko olusebenzayo ngeSihlomelo H se-IEC 60730-1, umenzi akanako ukubonelela ngekhowudi yomthombo we-BMS.

Kule meko, i-arhente yokuvavanya inokuvavanya ikhowudi yomthombo ngokuzimeleyo kunye nomvelisi we-BMS ukukhusela amalungelo epropathi yengqondo. Uhlalutyo olusebenzayo lokhuseleko lwesixokelelwano sebhetri lubalulekile, kwaye uvavanyo alunakurhoxiswa ngenxa yokuba umenzi webhetri engenakho ukunika ikhowudi yemvelaphi.

Okwangoku, isisombululo sisesisisombululo sethutyana kwaye siya kuvunywa kwintlanganiso yocweyo ye-CTL ngo-2024.(PDSH 2230)

I-IEC 63056: 2020: umbane wovavanyo lokumelana ne-insulation

I-IEC 63056: 2020 Isiqendu 7.4 (Ukuhlolwa kokufakelwa kombane ngexesha lokuthutha kunye nokufakwa) kubhekiselele kwi-IEC 62133: 2017 yokuvavanya ukuchasana kwe-insulation. Le yimpazamo yokuhlela. Isalathiso kufuneka sibe yi-IEC 62133-2: 2017. Le mpazamo yazisiwe kwi-IEC TC21A.

Umgangatho we-IEC 63056 unokugubungela iimveliso ezinomthamo omkhulu we-1500Vdc, kodwa uvavanyo lovavanyo lwe-IEC 62133-2: 2017 luyi-500Vdc. Ukuba i-voltage ephezulu yenkqubo yebhetri idlula i-500Vdc, yeyiphi i-voltage yokuvavanya kufuneka isetyenziswe?

Uvavanyo lokumelana ne-insulation lusasebenzisa i-IEC 62133-2: 2017 5.2 yokuvavanya. Iingcingo kunye ne-insulation kufuneka zibe ngokwaneleyo ukumelana nomthamo ophezulu olindelekileyo kwaye zivavanywe ngokweemfuno ze-IEC 60950-1: 2005, 3.1 kunye ne-3.2 (bhekisa kwi-IEC 63056: 2020 igatya 5.2).

Bhekisela kumfanekiso ongezantsi, xa usenza uvavanyo lokumelana ne-insulation, kukho iindlela ezimbini zokudibanisa umhloli wokumelana nokukhusela. Xa isixhobo sovavanyo kunye nesampulu yovavanyo ziqhagamshelwe kuthotho, ii-voltages zazo ziya kubekwa ngaphezulu, kwaye enye i-insulation yenkqubo yebhetri inokumelana novavanyo lombane olungaphaya koluhlu. Ngaba uvavanyo lwechungechunge kufuneka lwenziwe ngeli xesha?

Uqhagamshelo lothotho olunokuthi lubangele i-voltage superposition alufanelekanga. Isizathu salo mahluko kukuba injongo ye-IEC 63056: 2020 kukulinganisa "ukuchasana kwe-insulation yoqhagamshelwano lwe-DC kunye nenkqubo yomqhubi wokukhusela amandla". Injongo ye-IEC 62133-2: 2017 kukulinganisa "ukunganyangeki kwe-insulation phakathi kwe-terminal eqinisekileyo yebhetri kunye nomphezulu wesinyithi oveziweyo wangaphandle (ngaphandle koqhagamshelwano lombane). Okwangoku, esi sigqibo sisesisisombululo sethutyana kwaye siya kuvunywa kwintlanganiso yocweyo ye-CTL ngo-2024.(PDSH 2229)
