Amabhethri ayisipele esibhedlela angehlisa izinga kancane kancane futhi angaqashelwa phakathi kokuhlolwa mathupha. Lesi sihloko sichaza izinselele ezibalulekile zokunakekela kanye nendlela ukuqapha okuqhubekayo kwebhethri ngayinye ye-DFUN BMS neyunithi yezinhlamvu - ukumboza amandla kagesi, izinga lokushisa, ukumelana kwangaphakathi, i-SOC ne-SOH - kusiza izibhedlela ukuthi zibambe amabhethri abuthakathaka kusenesikhathi, okuboniswa ngekesi langempela lokuthunyelwa esibhedlela saseJalimane.

Ukumelana kwangaphakathi kungenye yezinkomba zakuqala ezinokwethenjelwa kakhulu zempilo yebhethri ye-VRLA, kodwa ayikho inombolo eyodwa yendawo yonke ekutshela ukuthi ulishintsha nini ibhethri — ukufunda kusho okuthile kuphela ngokumelene nesisekelo seseli uqobo. Lesi sihloko sephula umthetho wokushintsha ongu-50%-ngenhla-oyisisekelo, isheke lokuchezuka kweseli kuya kuseli elingu-20–30% ukuze libone iyunithi elibambekayo, nokuthi kungani ukweqa okungazelelwe kokumelana kubaluleke ngaphezu kwenani eliphelele eliphezulu. Iphinde ihlanganise ukuthi kungani ukumelana kukodwa kungenele - ukumatanisa nokuhlolwa kwamandla e-float, ukuhlolwa kokukhishwa komthamo, nokuhlola okubukwayo - nokuthi inkundla yokuqapha ibhethri ehlanganisiwe ye-DFUN kanye nenkundla yokuhlola umthamo yenza kanjani ukulandelelwa komkhawulo kuyo yonke iyunithi yezinhlamvu.

Amabhethri agcwele i-lead-acid kanye ne-Ni-Cd ahlala ebalulekile kumandla ayisipele e-DC abalulekile, kodwa ukuhlola okwenziwa ngesandla akukwazi ukunikeza ukubonakala okuqhubekayo empilweni yebhethri. Thola ukuthi i-DFUN BMS iqapha kanjani amandla kagesi, izinga lokushisa, ukumelana kwangaphakathi, i-SOC, i-SOH, izinga le-electrolyte nokuvuza kwetheminali—izinsiza ezisiza kanye nabaqhubi bezimboni ukuthi babone amaphutha kusenesikhathi, banciphise umthwalo wokulungisa futhi bathuthukise ukwethembeka kwamandla okulondoloza.

Ezindaweni ezibalulekile zemishini ezifana nezikhumulo zezindiza, izikhungo zedatha, namakhampasi amakhulu, ukwethembeka kwamandla okulondoloza kubalulekile. Ukuphatha izinkulungwane zamabhethri ezinhlelweni ze-UPS sekuya ngokuya kuba nzima, futhi izindlela zokunakekela ezivamile azisanele.

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.

Njengoba izinhlelo zezokuthutha zasemadolobheni ziqhubeka nokwenza isimanjemanje, ukuqinisekisa ukwethembeka kokunikezwa kwamandla okuphuthumayo sekuyisidingo esibalulekile sokuphepha. Ekusetshenzisweni kwakamuva, i-DFUN ngokuziqhenya yethule isixazululo esiphelele seBattery Monitoring System (BMS) ohlelweni lwePrague Metro e-Czech Republic.
