Isilinganiso samanje esinembile Ezinhlelweni Zokuphatha Ibhethri (BMS) sinquma imingcele yokuphepha yamabhethri e-lithium-ion kuzo zonke izimoto zikagesi nokufakwa kwesitoreji samandla. Ucwaningo lwakamuva lwemboni luveza ukuthi ngaphezu kuka-23% wezigameko zokushisa kwebhethri zibangelwa ukukhukhuleka kokulinganisa kumasekhethi okuvikela.
Ukulinganisa kwamanje kwe-BMS kuqinisekisa imikhawulo ebalulekile yokukhokhiswa ngokweqile, ukukhipha ngokweqile, nomsebenzi wokuvikela isifunda esifushane njengoba kudizayinwe. Uma ukunemba kokulinganisa kwehla, amabhethri angase asebenze ngaphezu kwamafasitela okusebenza aphephile - okungase kuholele ekubalekeni okushisayo. Inqubo yokulinganisa ihlanganisa:
- Ukuqinisekiswa kwesisekeloUkusebenzisa ama-multimeters aqinisekisiwe ukuze kuqinisekiswe amareferensi amanje ngokumelene nokufundwa kwe-BMS. Imishini yokulinganisa yezinga lezimboni kufanele ifinyelele ≤0.5% yokubekezelela.
- Isinxephezelo SephuthaUkulungisa ama-coefficient e-firmware ebhodi lokuvikela lapho ukungezwani kudlula izicaciso zomkhiqizi. I-BMS yezinga lezimoto ngokuvamile idinga ukuchezuka kwamanje okungu-≤1%.
- Ukuqinisekiswa Kwe-Stress-TestUkusebenzisa imijikelezo yokulayisha efanisiwe ukusuka ku-10% -200% umthamo olinganiselwe kuqinisekisa ukuzinza kokulinganiswa ngaphansi kwezimo zomhlaba wangempela.
UDkt. Elena Rodriguez, umcwaningi wezokuphepha kwebhethri eMunich Technical Institute, uthi: “I-BMS engalinganisiwe ifana namabhande ezihlalo okungaziwa ukuthi agqabuke khona. "Ukulinganisa kwamanje kwaminyaka yonke akufanele kuxoxwe ngezinhlelo zokusebenza zamandla aphezulu."
Imikhuba emihle ihlanganisa:
- Kusetshenziswa izindawo ezilawulwa izinga lokushisa (±2°C) ngesikhathi sokulinganisa
- Ukuqinisekisa ukuqondanisa kwenzwa yeHholo ngaphambi kokulungiswa
- Ukubhala ukubekezelela kwangaphambili/ngemuva kokulinganisa emikhondo yocwaningo
Izindinganiso zokuphepha zomhlaba wonke ezihlanganisa i-UL 1973 ne-IEC 62619 manje zigunyaza amarekhodi okulinganisa okusetshenziswa kwebhethri esikalini segridi. Amalebhu okuhlola ezinkampani zangaphandle abika isitifiketi esisheshayo esingu-30% kumasistimu anemilando yokulinganisa eqinisekisekayo.
