Njengamanje, amabhethri e-lithium asetshenziswa kabanzi kumadivayisi ahlukahlukene edijithali afana nezincwadi, amakhamera edijithali, namakhamera evidiyo edijithali. Ngaphezu kwalokho, futhi banamathemba abanzi ezimotweni, eziteshini eziyisisekelo zamaselula, neziteshi zikagesi zokugcina amandla. Kulokhu, ukusetshenziswa kwamabhethri akusaveli wodwa njengakumaselula, kodwa ngaphezulu ngendlela yochungechunge noma amaphakethe ebhethri ahambisanayo.
Umthamo nempilo yebhethri yephakethe akuhlobene kuphela nebhethri elilodwa, kodwa futhi kuhlobene nokungaguquguquki phakathi kwebhethri ngalinye. Ukungaguquguquki okungalungile kuzodonsela phansi kakhulu ukusebenza kwephakethe lebhethri. Ukuvumelana kokuzikhulula kuyingxenye ebalulekile yezici ezithonya. Ibhethri elizikhiphayo ngokungahambisani lizoba nomehluko omkhulu ku-SOC ngemva kwesikhathi sokugcina, okuzothinta kakhulu umthamo nokuphepha kwalo.
Kungani kwenzeka ukuzikhulula?
Uma ibhethri ivuliwe, ukusabela okungenhla akwenzeki, kodwa amandla azokwehla, okubangelwa ikakhulukazi ukuzikhipha kwebhethri. Izizathu eziyinhloko zokuzikhulula yizi:
a. Ukuvuza kwe-electron yangaphakathi okubangelwa ukuqhutshwa kwe-electron yendawo ye-electrolyte noma ezinye izifunda ezimfushane zangaphakathi.
b. Ukuvuza kukagesi kwangaphandle ngenxa yokungagxili kahle kwezigxivizo zebhethri noma ama-gaskets noma ukumelana okunganele phakathi kwamagobolondo omthofu angaphandle (ama-conductor angaphandle, umswakama).
c. Ukusabela kwe-Electrode/electrolyte, njengokugqwala kwe-anode noma ukuncishiswa kwe-cathode ngenxa ye-electrolyte, ukungcola.
d. Ukubola kwengxenye yezinto ezisebenzayo ze-electrode.
e. I-passivation yama-electrode ngenxa yemikhiqizo yokubola (ama-insoluble namagesi adsorbed).
f. I-electrode igqokwa ngomshini noma ukumelana phakathi kwe-electrode kanye nomqoqi wamanje kuba kukhudlwana.
Umthelela wokuzikhulula
Ukuzikhipha ngokwakho kuholela ekwehleni komthamo ngesikhathi sokugcina.Izinkinga ezimbalwa ezijwayelekile ezibangelwa ukuzikhipha ngokweqile:
1. Imoto isipakwe isikhathi eside futhi ayikwazi ukulayishwa;
2. Ngaphambi kokuba ibhethri ifakwe endaweni yokugcina, i-voltage nezinye izinto zivamile, futhi kutholakala ukuthi i-voltage iphansi noma i-zero uma ithunyelwa;
3. Ehlobo, uma i-GPS yemoto ibekwe emotweni, amandla noma isikhathi sokusebenzisa sizobe singanele ngemva kwesikhathi esithile, ngisho noma ibhethri liqhuma.
Ukuzikhipha ngokwakho kuholela ekwandeni komehluko we-SOC phakathi kwamabhethri nokuncipha komthamo wephakethe lebhethri
Ngenxa yokungaguquki kokuzikhipha kwebhethri, i-SOC yebhethri ephaketheni lebhethri izohluka ngemuva kokugcinwa, futhi ukusebenza kwebhethri kuzokwehla. Amakhasimende ngokuvamile angathola inkinga yokonakala kokusebenza ngemva kokuthola iphakethe lebhethri eligcinwe isikhathi esithile. Lapho umehluko we-SOC ufinyelela cishe ku-20%, umthamo webhethri elihlanganisiwe ungama-60% ~ 70% kuphela.
Indlela yokuxazulula inkinga yokuhluka okukhulu kwe-SOC okubangelwa ukuzikhipha?
Kalula nje, Sidinga kuphela ukulinganisela amandla ebhethri futhi sidlulisele amandla eseli ye-voltage ephezulu kwiseli ene-voltage ephansi. Njengamanje kunezindlela ezimbili: ukulinganisa okwenziwayo kanye nokulinganisa okusebenzayo
Ukulinganisa okwenziwayo ukuxhuma isixhasi sokulinganisa ngokuhambisana neseli yebhethri ngayinye. Uma iseli lifinyelela ku-overvoltage kusengaphambili, ibhethri isengashajwa futhi ishaje amanye amabhethri ane-low-voltage. Ukusebenza kahle kwale ndlela yokulinganisa akuphakeme, futhi amandla alahlekile alahlekile ngendlela yokushisa. Ukulinganisa kufanele kwenziwe kumodi yokushaja, futhi ukulinganisa kwamanje ngokuvamile kungu-30mA kuya ku-100mA.
Isilinganisi esisebenzayongokuvamile ibhalansisa ibhethri ngokudlulisela amandla futhi idlulise amandla amaseli nge-voltage eyeqile kwamanye amaseli ane-voltage ephansi. Le ndlela yokulinganisa isebenza kahle kakhulu futhi ingalinganiswa kuzo zombili izimo zokushaja nokukhipha. Isilinganiso sayo samanje sikhulu izikhathi eziningi kuneyamanje yokulinganisa yokwenziwa, ngokuvamile phakathi kuka-1A-10A.
