Kwiinkqubo zebhetri ye-lithium, ukuchaneka kwe-SOC (iState of Charge) uqikelelo luyimilinganiselo ebalulekileyo yokusebenza kweNkqubo yoLawulo lweBattery (BMS). Ngaphantsi kweendawo ezahlukeneyo zobushushu, lo msebenzi uba ngumngeni ngakumbi. Namhlanje, singena kwingqikelelo efihlakeleyo kodwa ebalulekileyo yobugcisa—zero-drift okwangoku, echaphazela kakhulu ukuchaneka koqikelelo lwe-SOC.
Yintoni i-Zero-Drift yangoku?
I-Zero-drift current ibhekisa kumqondiso wangoku wobuxoki owenziwe kwisekethe yeamplifier xa kukhoigalelo elinguziro langoku, kodwa ngenxa yezinto ezifanautshintsho lobushushu okanye ukungazinzi konikezelo lwamandla, indawo yokusebenza engatshintshiyo ye-amplifier shifts. Olu tshintsho luye lube nokwandiswa kwaye lubangela ukuba imveliso ijike kwixabiso elicetyiweyo elinguziro.
Ukuyicacisa ngokulula, yiba nomfanekiso-ngqondweni wesikali segumbi lokuhlambela ledijithali esibonisaI-5 kg yobunzima phambi kokuba nabani na anyathele kuyo. Obo bunzima “besiporho” bulingana ne-zero-drift current-uphawu olungekho ngokwenene.
Kutheni kuyingxaki kwiibhetri zeLithium?
I-SOC kwiibhetri ze-lithium zihlala zibalwa kusetyenziswaukubala coulomb, edibanisa yangoku ngokuhamba kwexesha.
Ukuba zero-drift yangokuiyakhuthaza kwaye iyazingisa, kusenokwenzekaphakamisa ngobuxoki SOC, ukukhohlisa inkqubo ekucingeni ukuba ibhetri ihlawuliswe kakhulu kunokuba injalo-mhlawumbi ukunqumla ukutshaja ngaphambi kwexesha. Ngokuchaseneyo,ukukhukuliseka okungalungangainokukhokelela kwii-SOC ijongelwe phantsi, ukuvuselela ukukhuselwa kwangaphambili kokukhutshwa.
Ngokuhamba kwexesha, ezi mpazamo zongezelekayo zinciphisa ukuthembeka kunye nokhuseleko lwenkqubo yebhetri.
Nangona i-zero-drift current ayinakususwa ngokupheleleyo, inokuthotywa ngokusebenzayo ngokudibanisa iindlela:
- Ukulungiswa kwezixhobo zokusebenza: Sebenzisa i-low-drift, i-op-amps echanekileyo ephezulu kunye namacandelo;
- Imbuyekezo ye-algorithmic: Lungelelanisa ngamandla ukukhukuliseka usebenzisa idatha yexesha lokwenyani njengobushushu, amandla ombane kunye nangoku;
- Ulawulo lobushushu: Lungiselela uyilo kunye nokutshatyalaliswa kobushushu ukunciphisa ukungalingani kwe-thermal;
- Ukuchaneka okuphezulu: Ukuphucula ukuchaneka kokufunyanwa kweparameter engundoqo (i-voltage yeseli, i-voltage yokupakisha, ubushushu, okwangoku) ukunciphisa iimpazamo zoqikelelo.
Ukuqukumbela, ukuchaneka kuyo yonke i-microamp ibala. Ukujongana ne-zero-drift yangoku linyathelo eliphambili lokwakha iinkqubo zolawulo lwebhetri ezikrelekrele nezithembekileyo.
