Emkhakheni wezinhlelo zokuphatha ibhethri (BMS), enye yezingozi ezinganakwa kakhulu kumabhethri e-lead-acid kanye ne-Ni-Cd i-ripple current kanye ne-ripple voltage. Nakuba ngokuvamile zingabonakali, lezi ziphazamiso zikagesi zisebenza njengababulali abathule, zinciphisa ubude bebhethri futhi zisongela ukuthembeka kwezinhlelo zamandla eziyisipele ezibucayi ezikhungweni zedatha, iziteshi ezincane, namasayithi okuxhumana ngocingo.
Inqubo ekahle yokushaja nokukhipha ibhethri kufanele ibe amandla e-DC abushelelezi. Kodwa-ke, ngenxa yokushintshwa kwemvamisa ephezulu kumashaja nezinhlelo ze-UPS, izingxenye ze-AC ezingafuneki ziyavela:
I-Ripple Yamanje - Ingxenye ye-AC ebekwe phezulu ku-DC yamanje, eguquguqukayo ngomthwalo kanye nemijikelezo yokushaja/yokukhipha.
I-Ripple Voltage - Ukuguquguquka kwe-AC okubekwe phezulu ku-voltage ye-DC, kukalwa ngamavelu e-peak-to-peak noma e-RMS.
Lawa ma-ripples ngokuvamile avela kububanzi obungu-50Hz – 1kHz futhi, nakuba engabonakali, akhona kuwo wonke umjikelezo wokushaja.
Kunoma iyiphi isistimu yokuqapha ibhethri, ukuziba i-ripple kuyingozi. Ngokuhamba kwesikhathi, i-ripple idala umonakalo ongalungiseki:
I-Accelerated Plate Corrosion - I-Ripple yamanje iholela ekuchithekeni kwezinto ezisebenzayo, ukunciphisa impilo yesevisi.
Ukushisa Okudlulele - I-Ripple yandisa ukumelana nokukhiqiza ukushisa; njalo ngo-10°C ukuphakama kuphinda kabili ukusabela kwamakhemikhali, kusheshisa ukuhwamuka kwe-electrolyte.
Ukulahlekelwa Amandla - Ukuchayeka kwe-ripple yesikhathi eside kunciphisa umthamo osebenzayo ngo-30-50%, kubukela phansi ukuqapha impilo yebhethri nokuthembeka kwesistimu.
Kungani Amasistimu Ajwayelekile Ebhethri e-BMS Anganele?
Izixazululo eziningi zebhethri ze-BMS zikala kuphela amapharamitha amile njenge-voltage kanye nezamanje, zinganaki imiphumela ye-ripple. Lokhu kufana nokuhlola izinga lokushisa lomzimba kodwa ukuziba ukushintshashintsha komfutho wegazi - izimpawu ezibucayi zempilo ziyageja.
Kungakho amasistimu okuqapha ibhethri athuthukile kufanele afake ukuqapha okunikelwe kwe - ripple ukuze kuqinisekiswe ukwethembeka kwangempela.
Njengomhlinzeki womhlaba wonke wezinhlelo zokuphatha amabhethri, i-DFUN inikezela ngochungechunge lwe-PBMS9000, oluklanyelwe ngokukhethekile izikhungo zedatha ezinkulu, iziteshi ezincane, nengqalasizinda ebalulekile. Kudlula ukuqapha kwendabuko ngokutholwa okuthuthukisiwe kwe-ripple:
1. Ukulinganisa Okunembe Kakhulu
I-Ripple Yamanje: 0~400A ukuphakama, 50Hz – 1kHz, ukulungiswa okungu-0.01A
I-Ripple Voltage: 2 ~ 100VDC ukuphakama, ukulungiswa kwe-0.01V
Ukuqapha okuhlanganisiwe kwe-voltage, ukumelana, i-SOC, i-SOH, nezinga lokushisa
2. 24/7 Ukuqapha Impilo Yebhethri
Ukuqapha okuku-inthanethi kwesikhathi sangempela nokugcinwa kwedatha yeminyaka emi-5
Ama-alamu anamazinga amaningi nge-SMS, i-imeyili, nohlelo lokusebenza lweselula, impendulo < 10s
3. Isistimu ye-BMS Enwebekayo futhi Eqinile
Isekela izintambo zamabhethri ezingafika kweziyisi-6 (amaseli angu-420 – 480) amabhethri e-VRLA kanye ne-Ni-Cd
Idizayini yokulwa nokuphazamiseka iqinisekisa ukusebenza okuthembekile ezindaweni ze-UPS
Isekela imigomo ye-Modbus, SNMP, MQTT, ne-IEC61850 yokuhlanganisa okungenamthungo
4. Isixazululo Esinokwethenjelwa, Esiqinisekisiwe
Ihambisana ne-CE, FCC, RoHS, izitifiketi ze-UL
Idizayini yamandla akabili iqinisekisa ukuthi ukuqapha akucishi
Kumaphrojekthi aphezulu anezikhungo zedatha ye-Google nezinye izinkampani ezinhlanu eziphezulu zomhlaba zesikhungo sedatha, uchungechunge lwe-PBMS9000 lubonise ukubaluleka kwalo.
Esikhungweni sedatha samazwe ngamazwe, i-PBMS9000 ithole ukungahambi kahle kwe-ripple kusasele izinyanga eziyi-6, ukuvimbela ukuphela kwe-UPS enkulu.
Ukuphila kwebhethri kunwetshwe ngo-40%, kunciphisa kakhulu izindleko zokushintshwa.
Amabhethri awumugqa wokugcina wokuzivikela kunoma iyiphi isistimu yokuphatha ibhethri, futhi i-ripple iwusongo olufihliwe kodwa olubi. Uchungechunge lwe-DFUN PBMS9000 luhlinzeka ngamakhono esistimu yokuqapha ibhethri yesizukulwane esilandelayo, iletha ukutholwa kwesikhathi sangempela kwe-ripple kanye nokuqapha impilo yebhethri ethuthukisiwe.
I-DFUN PBMS9000 — isixazululo se-BMS esihlakaniphe kakhudlwana, esiphephile, nesithembeke kakhulu samabhethri e-lead-acid kanye ne-Ni-Cd kumasistimu amandla abalulekile.
Xhumana ne-DFUN namuhla ukuze uthole ukuthi izixazululo zethu ze-BMS zebhethri ezithuthukisiwe zingayivikela kanjani ingqalasizinda yakho yamandla.
