Isingeniso:
Kalula nje, ukulinganisela kuyi-voltage yokulinganisela ephakathi. Gcina i-voltage ye-iphakethe lebhethri le-lithiumukuhambisana. Ukulinganisela kuhlukaniswe ngokulinganisela okusebenzayo kanye nokulinganisela okungasebenzi. Ngakho-ke uyini umehluko phakathi kokulinganisela okusebenzayo kanye nokulinganisela okungasebenzi kwebhodi lokuvikela ibhethri le-lithium? Ake sibheke i-Heltec Energy.
Ukulinganisa okusebenzayo kwebhodi lokuvikela ibhethri le-lithium
Ukulinganisela okusebenzayo ukuthi intambo ene-voltage ephezulu ifaka amandla kuntambo ene-voltage ephansi, ukuze amandla angachithwa, i-voltage ephezulu yehliswe, futhi i-voltage ephansi ingezwe. Lolu hlobo lwamandla okulinganisela asebenzayo lungazikhethela usayizi wamanje wokulinganisela. Ngokuyisisekelo, i-2A ivame ukusetshenziswa, futhi kukhona nezinkulu ezine-10A noma ngaphezulu.
Manje imishini yokulinganisela esebenzayo emakethe isebenzisa isimiso se-transformer, ithembele kuma-chip abizayo abakhiqizi bama-chip. Ngaphezu kwe-chip yokulinganisela, kukhona nezingxenye ezibizayo zangaphandle ezifana nama-transformer, amakhulu ngobukhulu futhi abiza kakhulu.
Umphumela wokulinganisela okusebenzayo usobala kakhulu: ukusebenza kahle okuphezulu, amandla amancane ayaguqulwa futhi awanyamalali ngesimo sokushisa, futhi okuwukuphela kokulahlekelwa yi-coil ye-transformer.
Umshini wokulinganisela ungakhethwa futhi isivinini sokulinganisela siyashesha. Ukulinganisela okusebenzayo kuyinkimbinkimbi kakhulu ngesakhiwo kunokulinganisela okungasebenzi, ikakhulukazi indlela ye-transformer. Intengo ye-BMS enomsebenzi wokulinganisela okusebenzayo izoba phezulu kakhulu kuneyokulinganisela okungasebenzi, okuphinde kunciphise kancane ukukhuthazwa kokulinganisela okusebenzayoI-BMS.
Ukulinganisa okungasebenzi kwebhodi lokuvikela ibhethri le-lithium
Ukulinganisa okungasebenzi kwenziwa ngokufaka ama-resistor ekukhipheni. Intambo yamaseli ene-voltage ephezulu ikhishwa ngendlela yokushabalalisa ukushisa endaweni ezungezile, okufeza umphumela wokupholisa i-resistor. Ububi ukuthi ukukhishwa kusekelwe kuntambo ye-voltage ephansi kakhulu, futhi kukhona ithuba lobungozi lapho kushajwa.
Ukulinganisela okungasebenzi kusetshenziswa kakhulu ngenxa yezindleko zayo eziphansi kanye nesimiso sayo sokusebenza esilula; ububi bayo ukuthi ilinganiselwe ngokusekelwe emandleni aphansi kakhulu, futhi ayikwazi ukwengeza intambo ye-voltage ephansi, okuholela ekuchithekeni kwamandla.
Umehluko phakathi kokulinganisela okusebenzayo nokulinganisela okungasebenzi
Ukulinganisela okungasebenzi kahle kufanelekile kuma-voltage amancane, aphansiamabhethri e-lithium, kuyilapho ukulinganisela okusebenzayo kufaneleka ezinhlelweni zokusebenza zebhethri le-lithium enamandla amakhulu, enamandla amakhulu.
Ubuchwepheshe bokushaja ngokulinganisela obusetshenziswa kakhulu buhlanganisa ukushaja ngokulinganisela kwe-shunt resistor, ukushaja ngokulinganisela kwe-shunt resistor on-off, ukushaja ngokulinganisela kwe-voltage yebhethri, ukushaja ngokulinganisela kwe-switch capacitor, ukushaja ngokulinganisela kwe-buck converter, ukushaja ngokulinganisela kwe-inductor, njll. Uma ushaja iqembu lamabhethri e-lithium ngokulandelana, ibhethri ngalinye kufanele lishajwe ngokulinganayo, ngaphandle kwalokho ukusebenza nokuphila kweqembu lonke lebhethri kuzothinteka ngesikhathi sokusebenzisa.

| Kuyasebenza | izimo Amabhethri amancane noma izinhlelo zokusebenza ezingabizi kakhulu | Amaphakethe amakhulu ebhethri noma izinhlelo zokusebenza ezisebenza kahle kakhulu |
Isimiso esiyisisekelo sokulinganisela okungapheli ukufeza umphumela wokulinganisela ngokuchitha amandla amaningi. Ngokuvamile, amandla amaningi kakhulu ephaketheni lebhethri elingaphezu kwamandla amaningi aguqulwa abe ukushisa nge-resistor, ukuze i-voltage yebhethri ihlale ifana. Inzuzo ukuthi isekethe yokulinganisela okungapheli ilula futhi izindleko zokuklama nokuqalisa ziphansi. Futhi ubuchwepheshe bokulinganisela okungapheli sebuvuthiwe kakhulu futhi busetshenziswe kabanzi ezindleleni eziningi ezishibhile nezincane.amaphakethe ebhethri.
Ububi ukuthi kunokulahleka okukhulu kwamandla ngenxa yokuguqulwa kwamandla kagesi abe ukushisa ngokumelana. Ukusebenza kahle okuphansi, ikakhulukazi kumabhethri amakhulu, imfucuza yamandla isobala kakhulu, futhi ayifanele ukusetshenziswa kwamabhethri amakhulu, asebenza kahle kakhulu. Futhi ngenxa yokuthi amandla kagesi aguqulwa abe ukushisa, angabangela ukuthi ibhethri lishise ngokweqile, okuthinta ukuphepha nokuphila kohlelo lonke.
Ukulinganisela okusebenzayo kufeza ukulinganisela ngokudlulisa amandla kagesi amaningi kusuka kumabhethri ane-voltage ephezulu kuya kumabhethri ane-voltage ephansi. Le ndlela ngokuvamile ilungisa ukusatshalaliswa kwamandla phakathi kwamabhethri ngokushintshanisa izinsiza zamandla, ama-buck-boost converters noma ezinye izingxenye ze-elekthronikhi. Inzuzo ukusebenza kahle okuphezulu: amandla awachithwa, kodwa alinganiswa ngokudluliselwa, ngakho-ke akukho ukulahleka kokushisa, futhi ukusebenza kahle kuvame ukuba phezulu (kufika ku-95% noma ngaphezulu).
Ukonga amandla: Njengoba kungekho mfucuza yamandla, ifaneleka kakhulu futhi isebenza kahle kakhuluibhethri le-lithiumizinhlelo futhi kungandisa impilo yesevisi yephakethe lebhethri. Kusebenza kumaphakethe amakhulu ebhethri: Ukulinganisela okusebenzayo kufaneleka kakhulu kumaphakethe ebhethri amakhulu, ikakhulukazi ezimweni ezifana nezimoto zikagesi nezinhlelo zokugcina amandla, futhi kungathuthukisa kakhulu ukusebenza kahle kwesistimu kanye nokukhuthazela.
Ububi ukuthi ukwakheka kanye nokusetshenziswa kokulinganisela okusebenzayo kuyinkimbinkimbi kakhulu, ngokuvamile kudinga izingxenye ze-elekthronikhi ezengeziwe, ngakho-ke izindleko ziphakeme. Ubunzima bobuchwepheshe: Ukulawula okunembile kanye nokuklama kwesekethe kuyadingeka, okuyinto enzima futhi engandisa ubunzima bokuthuthukiswa nokugcinwa.
Isiphetho
Uma kuyisistimu engabizi kakhulu, encane noma uhlelo lokusebenza olunezidingo eziphansi zokulinganisela, ukulinganisela okungasebenzi kungakhethwa; ezinhlelweni zebhethri ezidinga ukuphathwa kwamandla okusebenzayo, amandla amakhulu noma ukusebenza okuphezulu, ukulinganisela okusebenzayo kuyisinqumo esingcono.
I-Heltec Energy yinkampani ethuthukisa futhi ikhiqize imishini yokuhlola nokulungisa amabhethri esebenza kahle kakhulu, futhi inikeza izixazululo zokukhiqiza ngemuva, ukukhiqizwa kwe-pack assembly, kanye nokulungiswa kwamabhethri amadala.amabhethri e-lithium.
I-Heltec Energy ibilokhu igcizelela ekusungulweni kwezinto ezintsha ezizimele, ngenhloso eyinhloko yokuhlinzeka ngemikhiqizo ethembekile nengabizi kakhulu embonini yamabhethri e-lithium, kanye nomqondo wesevisi "wokugqama kwamakhasimende kuqala, ikhwalithi" ukuze kudalwe inani kumakhasimende. Ngesikhathi sokuthuthukiswa kwayo, inkampani inethimba lonjiniyela abaphezulu embonini, okuqinisekisa ngempumelelo intuthuko nokusebenza kahle kwemikhiqizo yayo.
Uma unemibuzo noma ungathanda ukwazi okwengeziwe, sicela ungangabazi ukungithumelelaxhumana nathi.
