Izisombululo zeTurnkey zokwenza umthamo kunye nokwahlulahlula iiseli ze-cylindrical

Inkcazo

1. Ifanelekile kwimveliso ephezulu, ekhawulezayo yeebhetri ze-lithium ezisilinda kwiinkqubo ezahlukeneyo, ezihambelanayo 18650 / 21700 / uthotho 34 / uthotho 46.

2. Ukusebenza kakuhle komgca kufikelela kwi 350 PPM kwiiseli ezincinci ezisilinda kunye 200 PPM kwiiseli ezinkulu ezisilinda.

Iingenelo zesisombululo

1. Ukusebenza kakuhle kakhulu

• Ubuchule bokuhlela obukhawulezayo kakhulu:

  • Iiseli ezincinci ezisilinda (18650 / 21700): isantya sokuhlela ukuya kuthi ga kwi 350 PPM (inkokheli yoshishino), umthamo wonyaka ngomgca ngamnye udlula 1,5 GWh, eyanelisa ukuveliswa ngobuninzi kweebhetri zamandla.

  • Iiseli ezinkulu ezisilinda (uthotho lwe-34/46): isantya sokuhlela ukuya kuthi ga kwi 200 PPM, elungelelaniswe neenkqubo zokudala umjikelo omde kwiiseli ezinomthamo ophezulu, ezinomthamo wonyaka odlula 1,0 GWh.

• Ulawulo loqeqesho oluchanekileyo:

  • Icebo le-CC-CV (i-constant current-constant voltage) elinamanqanaba amaninzi lokuphucula ukwakheka kwe-SEI layer, ukuphucula ubomi bomjikelo ngaphezu kwe 10%.

  • Ukuchaneka kolawulo lweVoltage kunye nolwangoku ≤ ±0,05%, kunye nokuphambuka komthamo 1% ngeseli nganye.

2. Ulawulo olukhethekileyo lobushushu

• Ulawulo lobushushu lwe-axial kunye ne-radial thermal:
  Isombulula imingeni yokupholisa engundoqo kwiiseli ezisilinda, ifezekisa ukulingana kobushushu ±0,5°C, ukuthintela ubushushu obugqithisileyo bendawo kunye nokuwohloka kokusebenza.

• Uhlengahlengiso lobushushu obuguqukayo ngexesha lokuhlela:
  Ilungisa ngokuzenzekelayo ubushushu bokutshaja/bokukhupha itshaja ngokwemeko ye-SOC, iqinisekisa ukuhlelwa okufanayo kunye nokusebenza ≥ 99,5%.

3. Izisombululo zokwenza izinto ngokuzenzekelayo ezenziwe ngokwezifiso

• Ukulayisha kunye nokuhlela ngokuzenzekelayo:

  • Iyahambelana nobubanzi 18/21/34/46 mm kunye nokuphakama 50–120 mm, kunye nexesha lokutshintsha imodeli imizuzu engama-30.

  • Sebenzisa umbono womatshini + umlinganiselo weleza ukuze kubekwe ngokuchanekileyo indawo, kuthintelwe ukuguquguquka kwendawo ebiyelweyo okubangelwa ziindlela zendabuko zokubambelela.

• Izixhobo zoqeqesho ezifana nezemagazini:

  • Isisombululo soqhagamshelwano lwe-impedance esiphantsi esenzelwe ngokukodwa iiseli ze-cylindrical, sinciphisa ukuguquguquka kwe-voltage, ngokuchaneka kokufunyanwa ±0,5 mV.

4. Uyilo olulungiselelwe ukonga amandla

• Ukhuphelo lokubuyisela amandla:
  Yenzelwe iimpawu zokukhupha umbane ophezulu kwiiseli ezisilinda, kunye nokusebenza kakuhle kokubuyisela amandla ≥ 85%ukonga okungaphezulu 30% amandla xa kuthelekiswa nokukhupha okuqhelekileyo okuxhathisayo.

• Iirakhi zokuhlela ezilungiselelweyo:
  Uqwalaselo lwetshaneli oluguquguqukayo ngokobukhulu beseli, okwandisa ukusetyenziswa kwendawo kwi 20%.

5. Ukulandeleka kwedatha

• Ukudibana okunzulu ne-MES:

  • Ukulandelela ii-curves zokwakheka, idatha yokwahlulahlula, kunye notshintsho lwangaphakathi lokumelana kweseli nganye, okuvumela uhlalutyo lwezizathu zeziphene (umz., ukufakwa kwe-lithium phezulu okanye i-solder ebuthathaka ezantsi, okuqhelekileyo kwiiseli ezisilinda).

  • Ukudibanisa ngokuzenzekelayo idatha yokwahlulahlula kunye neekhowudi eziphawulwe nge-laser, okuqinisekisa ukuhambelana komntu ngamnye phakathi kweseli kunye nedatha.
