Umqondo weukulinganisa amaselicishe kujwayelekile kwabaningi bethu. Lokhu kungenxa yokuthi ukuhambisana kwamanje kwamaseli akwanele, futhi ukulinganisela kusiza ukuthuthukisa lokhu. Njengoba nje ungakwazi ukuthola amaqabunga amabili afanayo emhlabeni, awukwazi futhi ukuthola amaseli amabili afanayo. Ngakho-ke, ekugcineni, ukulinganisa kuwukubhekana nokushiyeka kwamaseli, okusebenza njengesilinganiso sokubuyisela.
Yiziphi Izici Ezibonisa Ukungahambisani Kwamaseli?
Kunezici ezine eziyinhloko: i-SOC (Isimo Sokushaja), ukumelana kwangaphakathi, ugesi ozikhiphayo, kanye nomthamo. Kodwa-ke, ukulinganisela akukwazi ukuxazulula ngokuphelele lokhu kungafani okune. Ukulinganisela kungalungisa kuphela umehluko we-SOC, kuxazulule ukungalingani kokukhiphayo. Kodwa ngokumelana kwangaphakathi kanye nomthamo, ukulinganisela akunamandla.
Ukungalingani Kwamaseli Kubangelwa Kanjani?
Kunezizathu ezimbili eziyinhloko: esinye ukungaguquguquki okubangelwa ukukhiqizwa nokucubungula kwamaseli, kanti esinye ukungaguquguquki okubangelwa indawo yokusetshenziswa kwamaseli. Ukungaguquguquki kokukhiqiza kuvela ezintweni ezifana namasu okucubungula nezinto zokwakha, okuwukwenza kube lula inkinga eyinkimbinkimbi kakhulu. Ukungaguquguquki kwemvelo kulula ukukuqonda, njengoba indawo yeseli ngalinye ku-PACK ihlukile, okuholela ekungafanini kwemvelo njengokushintshashintsha okuncane kwezinga lokushisa. Ngokuhamba kwesikhathi, lokhu kuhlukahluka kuyanqwabelana, okubangela ukungaguquguquki kwamaseli.
Kusebenza Kanjani Ukulinganisela?
Njengoba kushiwo ngaphambili, ukulinganisela kusetshenziselwa ukuqeda umehluko we-SOC phakathi kwamaseli. Okungcono kakhulu, kugcina i-SOC yeseli ngalinye ifana, okuvumela wonke amaseli ukuthi afinyelele imikhawulo ye-voltage ephezulu nephansi yokushaja nokukhipha ngasikhathi sinye, ngaleyo ndlela kwandisa amandla asebenzisekayo ephaketheni lebhethri. Kunezimo ezimbili zomehluko we-SOC: esinye yilapho amandla eseli efana kodwa ama-SOC ahlukile; esinye yilapho amandla eseli nama-SOC womabili ehlukene.
Isimo sokuqala (esiphezulu kwesobunxele emfanekisweni ongezansi) sibonisa amaseli anomthamo ofanayo kodwa ama-SOC ahlukene. Iseli eline-SOC encane kunazo zonke lifinyelela umkhawulo wokukhishwa kuqala (uma sicabanga ukuthi i-25% SOC ingumkhawulo ophansi), kuyilapho iseli eline-SOC enkulu kunazo zonke lifinyelela umkhawulo wokushaja kuqala. Ngokulinganisela, wonke amaseli agcina i-SOC efanayo ngesikhathi sokushaja nokukhishwa.
Isimo sesibili (esesibili ukusuka kwesobunxele emfanekisweni ongezansi) sihilela amaseli anamakhono ahlukene nama-SOC. Lapha, iseli elinamandla amancane kakhulu liyashaja futhi likhiphe kuqala. Ngokulinganisela, wonke amaseli agcina i-SOC efanayo ngesikhathi sokushaja nokukhipha.
Ukubaluleka Kokulinganisela
Ukulinganisela umsebenzi obalulekile kumaseli amanje. Kunezinhlobo ezimbili zokulinganisela:ukulinganisela okusebenzayofuthiukulinganisela okungenamsebenzi. Ukulinganisela okungasebenzi kusebenzisa ama-resistor ukuze kukhishwe, kuyilapho ukulinganisela okusebenzayo kuhilela ukugeleza kweshaja phakathi kwamaseli. Kukhona impikiswano ethile ngala magama, kodwa ngeke singene kulokho. Ukulinganisela okungasebenzi kusetshenziswa kakhulu ekusebenzeni, kuyilapho ukulinganisela okusebenzayo kungavamile.
Ukunquma Umthamo Wokulinganisela we-BMS
Ukuze kulinganiswe ngendlela engasebenzisi amandla, kufanele kunqunywe kanjani ukuthi umsinga wokulinganisela ungakanani? Okungcono kakhulu, kufanele ube mkhulu ngangokunokwenzeka, kodwa izici ezifana nezindleko, ukushabalaliswa kokushisa, kanye nesikhala zidinga ukuvumelana.
Ngaphambi kokukhetha ugesi wokulinganisela, kubalulekile ukuqonda ukuthi umehluko we-SOC ubangelwa yini yisimo sokuqala noma sesibili. Ezimweni eziningi, usondele kakhulu kwisimo sokuqala: amaseli aqala ngomthamo ofanayo kanye ne-SOC, kodwa njengoba esetshenziswa, ikakhulukazi ngenxa yomehluko ekuzikhipheni, i-SOC yeseli ngalinye iyahluka kancane kancane. Ngakho-ke, ikhono lokulinganisela kufanele okungenani lisuse umthelela womehluko wokuzikhipha.
Uma wonke amaseli ebene-self-discharge efanayo, ukulinganisela bekungeke kudingeke. Kodwa uma kukhona umehluko ku-self-discharge current, kuzovela umehluko we-SOC, futhi ukulinganisela kuyadingeka ukuze kulungiswe lokhu. Ngaphezu kwalokho, njengoba isikhathi sokulinganisa esimaphakathi sansuku zonke sinqunyelwe kuyilapho i-self-discharge iqhubeka nsuku zonke, isici sesikhathi kumele sicatshangelwe.
