Kwiinkqubo zebhetri ye-lithium, ukuchaneka koqikelelo lwe-SOC (State of Charge) yindlela ebalulekileyo yokulinganisa ukusebenza kweNkqubo yoLawulo lweBhetri (BMS). Phantsi kweemeko zobushushu ezahlukeneyo, lo msebenzi uba nzima nangakumbi. Namhlanje, singena kwingcamango yobugcisa engabonakaliyo kodwa ebalulekileyo—umsinga ongekho manzi, nto leyo echaphazela kakhulu ukuchaneka koqikelelo lwe-SOC.
Yintoni iZero-Drift Current?
Umsinga we-Zero-drift ubhekisa kwisignali yombane engeyonyani eveliswa kwisekethe ye-amplifier xa kukhoingeniso yangoku engenaziro, kodwa ngenxa yezinto ezifanautshintsho lobushushu okanye ukungazinzi kombane, indawo yokusebenza engashukumiyo ye-amplifier iyatshintsha. Olu tshintsho luyanda kwaye lubangela ukuba imveliso itshintshe kwixabiso elibekiweyo elingu-zero.
Ukuyichaza ngokulula, khawucinge ngesikali segumbi lokuhlambela ledijithali esibonisaUbunzima obuyi-5 kg ngaphambi kokuba umntu ayinyatheleLoo bunzima "bomoya" bulingana nomsinga ohamba ungenzi nto—isignali engekhoyo ngokwenene.
Kutheni le nto iyinkinga kwiibhetri zeLithium?
I-SOC kwiibhetri ze-lithium idla ngokubalwa kusetyenziswaukubala i-coulomb, edibanisa i-current ngokuhamba kwexesha.
Ukuba umsinga we-zero-drift uokulungileyo nokuqhubekayo, isenokubangobuxoki phakamisa i-SOC, ikhohlisa inkqubo ukuba icinge ukuba ibhetri itshajiwe kakhulu kunokuba itshajiwe ngokwenene—mhlawumbi ingayi kutshajiswa kwangethuba.ukuphambuka okungalungangakunokukhokelela ekubenii-SOC engaphantsi, okubangela ukhuseleko lokukhupha umntwana kwangethuba.
Ngokuhamba kwexesha, ezi mpazamo ziqokelelweyo zinciphisa ukuthembeka nokhuseleko lwenkqubo yebhetri.
Nangona umsinga we-zero-drift ungenakucinywa ngokupheleleyo, unokunciphisa ngempumelelo ngokusebenzisa iindlela ezahlukeneyo:
- Ukulungiswa kwezixhobo zekhompyuthaSebenzisa ii-op-amps kunye neenxalenye ezisebenzisa amandla aphantsi, ezichanekileyo kakhulu;
- Imbuyekezo ye-algorithmic: Lungisa ngokutshintshayo ukuze ushukume usebenzisa idatha yexesha langempela efana nobushushu, i-voltage, kunye ne-current;
- Ulawulo lobushushu: Lungiselela ulwakhiwo kunye nokuchithwa kobushushu ukuze kuncitshiswe ukungalingani kobushushu;
- Ukuqonda okuchanekileyo: Phucula ukuchaneka kokufunyanwa kweeparameter zesitshixo (i-voltage yeseli, i-voltage yepakethi, ubushushu, umsinga) ukuze kuncitshiswe iimpazamo zoqikelelo.
Ukuqukumbela, ukuchaneka kwi-microamp nganye kubalulekile. Ukujongana nomsinga we-zero-drift linyathelo elibalulekileyo ekwakheni iinkqubo zolawulo lwebhetri ezikrelekrele nezithembekileyo.
