KwiForam ye-2020 of Hundreds of People's Association, usihlalo we-BYD ubhengeze uphuhliso lwebhetri entsha ye-lithium iron phosphate. Le bhetri imiselwe ukwandisa uxinano lwamandla kwiipakethe zebhetri ngama-50% kwaye iza kungena kwimveliso enkulu okokuqala kulo nyaka.
Yintoni isizathu sokuba kuthiwe “ibhetri yeblade”?
Igama elithi “ibhetri yeblade” livela kwimilo yayo. Ezi bhetri zithe tyaba kwaye zinde ngakumbi xa zithelekiswa neebhetri zesikwere zemveli, ezifana nemilo yeblade.
“Ibhetri yeblade” ibhekisa kwiseli enkulu yebhetri engaphezu kweemitha eziyi-0.6 ubude, eyenziwe yi-BYD. Ezi seli zicwangciswe ngoluhlu kwaye zifakwa kwiphakheji yebhetri njengezilayidi. Olu yilo luphucula ukusetyenziswa kwendawo kunye noxinano lwamandla kwiphakheji yebhetri yamandla. Ukongeza, iqinisekisa ukuba iiseli zebhetri zinendawo enkulu ngokwaneleyo yokusasaza ubushushu, ivumela ubushushu bangaphakathi ukuba buqhutywe ngaphandle, ngaloo ndlela buvumela uxinano lwamandla aphezulu.
Ubuchwepheshe bebhetri yeBlade
Itekhnoloji yebhetri yeblade ye-BYD isebenzisa ubude obutsha beseli ukwenza uyilo oluthe tyaba. Ngokwelungelo lomenzi le-BYD, ibhetri yeblade inokufikelela kubude obuphezulu be-2500mm, obungaphezulu ngokuphindwe kalishumi kunebhetri ye-lithium iron phosphate eqhelekileyo. Oku kuphucula kakhulu ukusebenza kakuhle kwepakethi yebhetri.
Xa kuthelekiswa nezisombululo zebhetri ye-aluminium case exande, iteknoloji yebhetri yeblade ikwabonelela ngokusasazwa kobushushu okungcono. Ngale teknoloji enelungelo lobunikazi, uxinano lwamandla oluthile lwebhetri ye-lithium-ion ngaphakathi komthamo webhetri eqhelekileyo lunokwandiswa ukusuka kwi-251Wh/L ukuya kwi-332Wh/L, ukonyuka okungaphezulu kwe-30%. Ukongeza, kuba ibhetri ngokwayo inokubonelela ngokuqinisa oomatshini, inkqubo yokuvelisa iipakethe ilula, inciphisa iindleko zokuvelisa.
Ilungelo lomenzi livumela ukuba iiseli ezininzi ezizimeleyo zibekwe ecaleni kwelinye kwibhetri, nto leyo egcina iindleko zezinto zokwakha kunye nezabasebenzi. Kulindeleke ukuba iindleko zizonke zincitshiswe ngama-30%.
Iingenelo ngaphezu kwezinye iibhetri zamandla
Ngokuphathelele izixhobo ze-electrode ezilungileyo nezingalunganga, iibhetri zamandla ezisetyenziswa kakhulu kwimarike namhlanje ziibhetri ze-ternary lithium kunye neebhetri ze-lithium iron phosphate, nganye ineenzuzo zayo. Iibhetri ze-ternary lithium-ion zahlulwe zaba yi-ternary-NCM (nickel-cobalt-manganese) kunye ne-ternary-NCA (nickel-cobalt-aluminium), apho i-ternary-NCM ithatha uninzi lwesabelo semarike.
Xa kuthelekiswa neebhetri ze-ternary lithium, iibhetri ze-lithium iron phosphate zikhuselekile kakhulu, ziphila ixesha elide lokujikeleza, kwaye zibiza kancinci, kodwa uxinano lwamandla azo alunasithuba sokuphucula.
Ukuba uxinano oluphantsi lwamandla ebhetri ye-lithium iron phosphate lungaphuculwa, imiba emininzi ingasonjululwa. Nangona oku kunokwenzeka ngokwethiyori, kunzima kakhulu. Ke ngoko, yiteknoloji ye-CTP (ukuya kwi-cell to pack) kuphela enokwandisa uxinano lwamandla oluthile lwebhetri ngaphandle kokutshintsha izinto ze-electrode ezilungileyo nezingalunganga.
Iingxelo zibonisa ukuba ubunzima bebhetri ye-BYD's blade bunokufikelela kwi-180Wh/kg, malunga ne-9% ngaphezulu kunangaphambili. Olu buchule lufana nebhetri ye-“811″ ternary lithium, oko kuthetha ukuba ibhetri ye-blade igcina ukhuseleko oluphezulu, uzinzo, kunye neendleko eziphantsi ngelixa ifikelela kubunzima bebhetri ye-ternary lithium ephezulu.
Nangona ubunzima bebhetri yeblade ye-BYD buphezulu nge-9% kunesizukulwana esidlulileyo, ubunzima be-volume-specific energy bunyuke nge-50%. Le yeyona nzuzo yokwenyani yebhetri yeblade.
Ibhetri yeBlade yeBYD: Isicelo kunye nesikhokelo se-DIY
Usetyenziso lwebhetri yeBlade yeBYD
