Iimotoiibhetri zamandla e-lithiumbaye bayiguqula indlela esicinga ngayo ngezothutho.Baye baduma ngakumbi ngenxa yokuxinana kwamandla aphezulu, ubomi obude, kunye nokukwazi ukutshaja ngokukhawuleza.Nangona kunjalo, njengayo nayiphi na iteknoloji, beza kunye nokusebenza kwabo kunye nemiba yokhuseleko.
Ukusebenza kweemotoibhetri yamandla e-lithiumibalulekile ekusebenzeni kwayo kunye nokuphila ixesha elide.Enye yezona zinto zixhalabisayo ngeebhetri zamandla e-lithium kukuhla komthamo wazo ngokuhamba kwexesha.Njengoko ibhetri itshajwa kwaye ikhutshwa ngokuphindaphindiweyo, izinto ezisebenzayo ngaphakathi ziwohloka ngokuthe ngcembe, nto leyo ekhokelela ekuncipheni kumthamo webhetri iyonke.Ukuchasana nalo mbandela, abavelisi baye baqhubeka besebenza ekuphuculeni izinto ze-electrode yebhetri kunye ne-electrolyte formulations, echaphazela ngokuthe ngqo ukusebenza kwebhetri.
Omnye umba wokusebenza ovela kunyeiibhetri zamandla e-lithiumyinto yokubaleka kwe-thermal.Oku kwenzeka xa ibhetri ifumana ukunyuka okungalawulekiyo kwiqondo lokushisa, okukhokelela ekunyuseni okuzinzileyo ekuveliseni ubushushu.Ukubaleka kwe-thermal kunokuvuswa zizinto ezahlukeneyo, ezinjengokutshaja kakhulu, ukukhupha kakhulu, ukodlula iqondo lobushushu, okanye ukonakala komzimba kwibhetri.Nje ukuba i-thermal iqalwe, inokubangela ukusilela okuyingozi, kubangele imililo okanye uqhushumbo.
Ukunciphisa imingcipheko yokhuseleko ehambelana neebhetri zamandla e-lithium, amanyathelo amaninzi aphunyeziwe.Iisistim zolawulo lwebhetri (BMS) zidlala indima ebalulekileyo ekujongeni nasekulawuleni ubushushu bebhetri, amandla ombane kunye namanqanaba angoku.Ukuba iparameter iya ngaphaya koluhlu olukhuselekileyo, i-BMS inokuthatha amanyathelo okukhusela, njengokuvala ibhetri okanye ukuvula iinkqubo zokupholisa.Ukongeza, abavelisi baye baphumeza izinto ezahlukeneyo zokhuseleko, kubandakanywa izivalo zebhetri ezibuyiswa ngumlilo kunye nezinto eziphambili ze-elektroniki, ukunciphisa umngcipheko wokubaleka ubushushu.
Ngaphaya koko, uphando luyenziwa ukuphuhlisa imathiriyeli entsha kunye noyilo olonyusa ukhuseleko lweebhetri zamandla e-lithium.Enye indlela ethembisayo kukusetyenziswa kwee-electrolyte zesimo esiqinileyo, ezinozinzo oluphezulu lwe-thermal xa kuthelekiswa nolwelo lwemveli lwe-electrolyte.Iibhetri ezikwimeko eqinileyo ayinciphisi nje kuphela umngcipheko wokubaleka ubushushu kodwa ikwabonelela ngamandla oxinaniso lwamandla, ubomi obude, kunye nesantya sokutshaja ngokukhawuleza.Nangona kunjalo, ukuthengisa kwabo ngokubanzi kusasetyenzwa ngenxa yemiceli mngeni yokuvelisa kunye nokuqwalaselwa kweendleko.
Imimiselo kunye nemigangatho ibalulekile ekuqinisekiseni ukhuseleko kunye nokusebenza kweebhetri zamandla e-lithium yeemoto.Amaqumrhu angamazwe ngamazwe afana ne-International Electrotechnical Commission (IEC) kunye neZizwe eziManyeneyo ziye zaseka izikhokelo zokuvavanya nokuthuthwa kweebhetri ze-lithium.Abavelisi kufuneka balandele le mimiselo ukuqinisekisa ukuba zaboiibhetriukuhlangabezana neemfuno eziyimfuneko zokhuseleko.
Ukuqukumbela, ngelixa iibhetri zamandla e-lithium zemoto zibonelela ngeenzuzo ezininzi, ukusebenza kunye nemiba yokhuseleko ayifanele ihoywe.Uphando oluqhubekayo kunye nophuhliso lubalulekile ekwandiseni ukusebenza kwebhetri, ukunciphisa umngcipheko wokubaleka kwe-thermal, kunye nokuphucula ukhuseleko lwayo lonke.Ngokuphumeza iinkqubo zokulawula ibhetri ephucukileyo, kusetyenziswa izinto ezintsha, kunye nokuthobela imimiselo engqongqo, ishishini leemoto lingaqhubeka nokusebenzisa amandla ebhetri ye-lithium, ukuqinisekisa amava okuqhuba akhuselekileyo nasebenzayo kubathengi.
