Ukuthi ukuhlola umthamo webhethri okukude kanye nesistimu yokuqapha ibhethri ethuthukisiwe (i-BMS) kusiza kanjani iziteshi ezingaphansi zisebenze ngokuphepha ezindaweni eziphakeme kakhulu zokuphakama okuphezulu. Ngephrojekthi yomhlaba wangempela e-Tibet, i-DFUN ibonisa ukuthi ukuhlolwa kwamandla ebhethri aku-inthanethi kumabhange ebhethri ane-lead-acid kuthuthukisa kanjani ukwethembeka, kunciphisa izindleko zokunakekela, futhi kuqinisekisa amandla okulondoloza angaphazamiseki okusebenza kwegridi ebalulekile.

Eziteshini ezingaphansi, isistimu ye-DC isebenza 'njengomugqa wempilo' wezisetshenziswa ezibalulekile ezifana namasekhethi okulawula, ukuvikelwa kokudluliselana, kanye nezibani eziphuthumayo. Ibhange lebhethri, njengeyunithi yalo yokugcina amandla, lisebenza 'njengomugqa wokugcina wokuzivikela' phakathi nokuhluleka kwegridi. Nokho, ukugcinwa kwebhethri okuvamile kuyancika

Amandla okukhipha angempela amabhethri abesebenza ngaphansi kwezimo zokushaja okuntantayo isikhathi eside awavamile ukungaqondakali. Ukuthembela kuphela ezindleleni ezivamile zokuhlola umthamo kunikeza ukunemba okulinganiselwe. Nakuba izinguquko ku-voltage yebhethri nokumelana kwangaphakathi kungabonisa kancane

Ukuze kuhlolwe umthamo wamaphakethe ebhethri kumasistimu wamandla ayisipele, okwamanje kunezindlela ezimbili eziyinhloko: ukuhlola umthamo okuvamile nokuhlola umthamo we-inthanethi okukude. Ukuhlolwa kwamandla okuvamile kuncike ekuxhumeni ngesandla imithwalo ye-dummy ukuze ihlole ngayinye futhi iqinisekise amabhethri lapho ahlakazekile.
