Ukuba ubukhe wayibukela ibhetri ye-lithium iguga ngokungalinganiyo — ezinye iiseli zikwi-4.1V ngelixa ezinye zikwi-3.6V — sele uyaqonda ukuba kutheni ukulinganisela kubalulekile. Umbuzo awukokuba kufuneka ulinganisele na, kodwa kukuba kufuneka ulinganisele njani, kwaye oko kukhetha kubiza malini ebomini bephakheji.
Esi sikhokelo sithelekisa i-BMS yokulinganisela esebenzayo kunye ne-BMS yokulinganisela engashukumiyo kunye nesikhokelo esithile sokuba yeyiphi indlela efanelekileyo kwisicelo sakho.
Yintoni Ukulinganisela Iiseli kwi-BMS?
Ipakethi yebhetri ye-lithium ineeseli ezininzi ezidityaniswe ngothotho. Ngokwenyani, iiseli zahlukile kancinci ngomthamo, ukumelana kwangaphakathi, kunye nesantya sokuzikhupha. Ngokuhamba kwexesha, la mahluko ayahlangana. Iseli ebuthathaka ifikelela kumda wayo wevolthi kuqala - ngexesha lokutshaja ifika eluphahleni; ngexesha lokukhutshelwa ifika phantsi. I-BMS inqumla yonke ipakethi ukukhusela loo seli inye, nangona iiseli ezinamandla zisenamandla okusebenziseka.
Ukulinganisela iiseli kulungisa la mahluko, kwandisa amandla okusetyenziswa kunye nokucothisa ukonakala kwepakethi. Kukho iindlela ezimbini ezahlukeneyo ngokupheleleyo.

Imibuzo ebuzwa qho
Ndingayongeza i-active balancer kwipakethi esele ine-BMS engasebenziyo?
Ewe. I-DALY ikwabonelela ngeemodyuli ze-balancer ezisebenzayo ezizimeleyo ezongeza kwiphakheji ekhoyo ecaleni kwe-BMS engasebenziyo. I-balancer esebenzayo iphatha ukulingana kweeseli; i-BMS engasebenziyo iphatha imisebenzi yokukhusela. → Jonga iimodyuli ze-balancer ezisebenzayo ze-DALY: /active-balancer/
Ngaba ukulinganisela okusebenzayo kusebenza ngexesha lokukhupha, okanye kuphela ngexesha lokutshaja?
Ukulinganisela okusebenzayo kusebenza nakweyiphi na imeko yokutshaja — ngexesha lokutshaja, ukukhupha, naxa uphumle. Le yenye yeenzuzo zayo eziphambili ngaphezu kokulinganisela okungasebenziyo, okusebenzayo kuphela xa kuphantse kwatshaja ngokupheleleyo.
Ngowuphi umahluko we-voltage obangela ukulinganisela okusebenzayo?
I-DALY active balancing BMS ibangela i-balance xa umahluko phakathi kwe-voltage ephezulu neyeyona iphantsi yeseli idlula umda omiselweyo, omiselwe ngokuzenzekelayo kwi-20–30 mV.
Ngaba ukulinganisela okusebenzayo kuyahambelana nekhemistri yeLiFePO4?
Ewe. I-LiFePO4 ngokukodwa ixhamla kwi-active balancing kuba i-flat discharge curve yayo yenza i-passive balancing ingasebenzi kakuhle — umahluko omncinci we-voltage phezulu kwetshaja uhambelana nomahluko omkhulu we-capacity.
