Iuhlelo lwebhethriiyingqikithi yesistimu yokugcina amandla yonke, equkethe amakhulu amaseli ayisilinda nomaamaseli e-prismaticngochungechunge nangokuhambisana. Ukungahambisani kwamabhethri okugcina amandla kubhekisela kakhulu ekungahambelani kwamapharamitha afana nomthamo webhethri, ukumelana kwangaphakathi, kanye nokushisa. Uma amabhethri angahambisani esetshenziswa ochungechungeni nangokuhambisana, kuzovela izinkinga ezilandelayo:

1. Ukulahlekelwa amandla atholakalayo

Kuhlelo lokugcina amandla, amaseli angawodwa axhunywe ngochungechunge nangokuhambisana ukuze akhe ibhokisi lebhethri, amabhokisi ebhethri axhunywe ngochungechunge nangokuhambisana ukuze akhe iqembu lebhethri, futhi amaqoqo amaningi ebhethri axhunywe ngqo kubha yebhasi ye-DC efanayo ngokuhambisana. Izimbangela zokungahambisani kwebhethri okuholela ekulahlekelweni kwamandla asebenzisekayo zifaka phakathi ukungahambisani kochungechunge kanye nokungahambisani okufanayo.

•Ukulahlekelwa ukungalingani kochungechunge lwebhethri
Ngokomgomo webhareli, umthamo wochungechunge lwesistimu yebhethri uncike ebhethrini elilodwa elinomthamo omncane kakhulu. Ngenxa yokungahambisani kwebhethri elilodwa ngokwalo, umehluko wokushisa nokunye ukungahambisani, umthamo ongasetshenziswa webhethri ngalinye uzohluka. Ibhethri elilodwa elinomthamo omncane lishajwa ngokugcwele lapho lishajwa futhi lithululwe lapho likhishwa, okuvimbela ukushajwa kwamanye amabhethri elilodwa ohlelweni lwebhethri. Umthamo wokukhipha, okuholela ekwehleni komthamo otholakalayo wesistimu yebhethri. Ngaphandle kokuphathwa okulinganiselayo okusebenzayo, ngokwanda kwesikhathi sokusebenza, ukuncishiswa nokwehlukaniswa komthamo webhethri elilodwa kuzoqiniswa, futhi umthamo otholakalayo wesistimu yebhethri uzosheshisa kakhulu ukwehla.

•Ukulahlekelwa kokungalingani kweqembu lebhethri

Uma amaqoqo ebhethri exhunywe ngqo ngesikhathi esifanayo, kuzoba khona isenzakalo samandla ajikelezayo ngemva kokushaja nokukhipha, futhi ama-voltage eqoqo ngalinye lebhethri azophoqeleka ukulinganisela. Ukunganeliseki nokukhishwa okungapheli kuzobangela ukulahlekelwa umthamo webhethri kanye nokwenyuka kwezinga lokushisa, kusheshise ukubola kwebhethri, futhi kunciphise umthamo otholakalayo wesistimu yebhethri.

Ngaphezu kwalokho, ngenxa yokumelana okuncane kwangaphakathi kwebhethri, noma ngabe umehluko we-voltage phakathi kwamaqoqo okubangelwa ukungahambisani kungama-volt ambalwa kuphela, ugesi ongalingani phakathi kwamaqoqo uzoba mkhulu. Njengoba kuboniswe kudatha elinganisiwe yesiteshi sikagesi kuthebula elingezansi, umehluko kugesi wokushaja ufinyelela ku-75A (Uma kuqhathaniswa nesilinganiso sethiyori, ukuphambuka kungu-42%), kanti ugesi wokuphambuka uzoholela ekushajeni ngokweqile nasekuchitheni ngokweqile kwamanye amaqoqo ebhethri; kuzothinta kakhulu ukusebenza kahle kokushaja nokukhipha, impilo yebhethri, futhi kuholele ngisho nasezingozini zokuphepha ezinkulu.

2. Ukuhlukaniswa okusheshayo kanye nokuphila okufushane kwamaseli angawodwa okubangelwa ukushisa okungaguquguquki

Izinga lokushisa liyisici esibaluleke kakhulu esithinta impilo yesistimu yokugcina amandla. Lapho izinga lokushisa langaphakathi lesistimu yokugcina amandla lenyuka ngo-15°C, impilo yesistimu izofinyezwa ngaphezu kwengxenye. Ibhethri le-lithium lizokhiqiza ukushisa okuningi ngesikhathi senqubo yokushaja nokukhipha, futhi umehluko wokushisa webhethri elilodwa uzokwandisa ukungalingani kokumelana kwangaphakathi kanye nomthamo, okuzoholela ekuhlukaniseni okusheshayo kwebhethri elilodwa, kufinyeze impilo yomjikelezo wesistimu yebhethri, futhi kubangele ngisho nezingozi zokuphepha.

Ungabhekana kanjani nokungahambisani kwamabhethri okugcina amandla?

Ukungahambisani kwebhethri kuyimbangela yezinkinga eziningi ezinhlelweni zokugcina amandla zamanje. Nakuba ukungahambisani kwebhethri kunzima ukukuqeda ngenxa yezici zamakhemikhali zamabhethri kanye nomthelela wendawo yokusetshenziswa, ubuchwepheshe bedijithali, ubuchwepheshe be-elekthronikhi yamandla kanye nobuchwepheshe bokugcina amandla bungahlanganiswa ukuze kusetshenziswe ugesi. Ukulawulwa kobuchwepheshe be-elekthronikhi kunciphisa umthelela wokungahambisani kwebhethri le-lithium, okungakhulisa kakhulu amandla angasetshenziswa ezinhlelweni zokugcina amandla futhi kuthuthukise ukuphepha kohlelo.

•Ubuchwepheshe bokulinganisela obusebenzayo buqapha i-voltage kanye nokushisa kwebhethri ngalinye ngesikhathi sangempela, buqeda ngokuphelele ukungahambisani kokuxhumeka kochungechunge lwebhethri, futhi bukhulisa amandla atholakalayo ohlelweni lokugcina amandla ngaphezu kuka-20% kulo lonke umjikelezo wokuphila.

•Ekuklanyweni kukagesi kohlelo lokugcina amandla, ukuphathwa kokushaja nokukhipha kweqoqo ngalinye lamabhethri kwenziwa ngokwehlukana, futhi amaqoqo amabhethri awaxhunywanga ngokuhambisana, okugwema inkinga yokujikeleza kwegazi ebangelwa ukuxhumana okuhambisanayo kwe-DC, futhi kuthuthukisa ngempumelelo amandla atholakalayo ohlelo.

•Ukulawula izinga lokushisa okunembile ukuze kwandiswe impilo yesistimu yokugcina amandla

Izinga lokushisa leseli ngalinye liyaqoqwa futhi liqashwe ngesikhathi sangempela. Ngokusebenzisa ukulingisa ukushisa kwe-CFD okunezinga ezintathu kanye nenani elikhulu ledatha yokuhlola, ukwakheka kokushisa kwesistimu yebhethri kwenziwa ngcono, ukuze umehluko omkhulu wokushisa phakathi kwamaseli angawodwa ohlelweni lwebhethri ube ngaphansi kuka-5 °C, futhi inkinga yokwehlukaniswa kweseli elilodwa okubangelwa ukungahambisani kwezinga lokushisa ixazululwe.

Ufuna ukukhiqiza ibhethri le-lithium elenziwe ngokwezifiso ngokwezidingo ezikhethekile, wamukelekile ukubonisana nethimba le-LIAO ukuthola imininingwane eyengeziwe.
