Kutheni iibhetri zigqithisa kwaye njani?

Ubushushu bebhetri buchaphazela ukusebenza kwesixhobo, umsebenzi wobomi, kunye nokhuseleko. Njengoko iibhetri izixhobo zamandla ukusuka kwii-smartphones ukuya kwizithuthi zombane, ukuqonda oonobangela kunye nokuthintela ubushushu obugqithisileyo kubalulekile. Eli nqaku libandakanya iindlela, iziphumo, kunye nezicwangciso zokuthintela ukufudumeza kwebhetri ukunceda abasebenzisi ukulawula iibhetri ngokufanelekileyo.

Yintoni iBattery Overheating?

Ubushushu bebhetri bungaphezulu kweqondo lobushushu uluhlu olukhuselekileyo lokusebenza. Ibhetri nganye inobushushu obufanelekileyo bokusebenza ngokufanelekileyo nangokukhuselekileyo kweekhemikhali. Ngaphezulu kwalo mda, ukusabela azinzi, kubeka umngcipheko welahleko yokusebenza kunye neengozi zokhuseleko.

Ukushisa kakhulu kuyingozi kuba ukunyuka kwamaqondo obushushu kukhawulezisa ukusabela kweekhemikhali, ukuvelisa ubushushu obuninzi kunye nokwanda kobushushu. Olu tshintsho luhle lunokunyuka ngokukhawuleza ukuba alulawulwa, lukhokelela kwiimeko ezinobungozi.

Iziphumo zeBattery Overheating

Ubushushu bebhetri buchaphazela ukusebenza kunye nokhuseleko ngeendlela ezininzi:

• Ukuthotywa kokusebenza: Amaqondo obushushu aphezulu akhawulezisa ukuguga kwebhetri, anciphise umthamo, kwaye acuthe ixesha lokusebenza. Amaqondo obushushu angaphezu kwe-25°C anokubunciphisa ubomi bebhetri ye-lithium-ion.
• I-Thermal Runaway (TR): Ukushisa ngokugqithiseleyo kunokubangela i-TR, apho ukunyuka kwamaqondo obushushu kubangela ukwanda kobushushu obungakumbi, okunokukhokelela kwimililo okanye ukuqhuma.
• Umonakalo womzimba: Ubushushu obude bunokonakalisa ngokungenakuguqulwa izakhiwo zangaphakathi, kubangele ukudumba, ukuvuza, okanye ukuguqulwa kunye nokubeka esichengeni imfezeko yebhetri.
• Ukuncitshiswa kokusebenza kakuhle: Iibhetri ezishushu kakhulu zinokuchasana okuphezulu kwangaphakathi, okukhokelela ekutshajweni okucothayo kunye nokusetyenziswa okufutshane.

Iimbangela zeBattery Overheating

Ukuqonda ukuba yintoni ebangela ukushisa okugqithisileyo kungundoqo ekuthinteleni. Oonobangela abaphambili baquka:

• Ukutshaja ngokukhawuleza okanye ukutshaja kakhulu: Ukutshaja ngaphaya kweenkcazo zebhetri kuvelisa ubushushu obugqithisileyo.
• Amaqondo obushushu aphezulu kwindawo: Ubushushu bangaphandle, njengokukhanya kwelanga okanye izithuthi ezishushu, bunqanda ukubuchitha ubushushu.
• Imeko yebhetri engalunganga okanye uyilo: Iibhetri ezindala, ezonakalisiweyo, ezikumgangatho ophantsi, okanye iziphene zokuvelisa zandisa ukuxhathisa kwangaphakathi kunye nobushushu.
• Iimfuno zamandla agqithisileyo: Imisinga ephezulu evela kwimisebenzi enzima (umdlalo, ustrimisho, izixhobo zombane) yenza ubunzima bebhetri.
• Ukungena komoya okungonelanga: Ukungaphumi kakuhle komoya kuthintela ukupholisa okufanelekileyo.
• Inkqubo yoLawulo lwebhetri (BMS) ukusilela: I-BMS ephosakeleyo ayikwazi ukulawula ubushushu okanye yangoku, ivumela iimeko ezingakhuselekanga.

Iimpawu zeBattery Overheating

UkuTshaja okucuthiweyo okanye ukuKhawuleza ngokuSebenzayo

Ukuqaphela iimpawu ezigqithisayo kuvumela ukungenelela kwangethuba ngaphambi kokuba kwenzeke umonakalo.

Ukuguqulwa okanye ukuDumba

Ukushisa okugqithisileyo kwandisa uxinzelelo lwangaphakathi, kubangela ukuba i-casing yebhetri iqhume okanye igqwethe. Oku kubonisa iingxaki ezinzulu zangaphakathi kwaye kufuna ingqalelo ngokukhawuleza.

Ivumba okanye Umsi

Ivumba elivuthayo okanye umsi libonisa ukuphuka okanye ukutshisa kwangaphakathi. Thatha inyathelo ngoko nangoko, njengoko ezi zihlala zandulela iimeko eziyingozi.

Ubushushu obuPhezulu ngokuNgaqhelekanga

Ukushisa okugqithisileyo okwenza iibhetri zingakhululeki ukubamba ngokucacileyo kubonisa ukutshisa kwaye akufanele kuhoywa.

UkuTshaja okucuthiweyo okanye ukuKhawuleza ngokuSebenzayo

Ukucutha ixesha lokubaleka okanye ukutshaja okucothayo kubonisa ukuba ukufudumeza kuyonakalisa ikhemistri yebhetri, kuthoba ukusebenza.

Ukuthelekisa iiMpawu zokuFuthumala kuzo zonke iintlobo zebhetri

UThintelwa Njani Ukushisa Okugqithisileyo Kwebhetri

Amanyathelo asebenzayo anciphisa imingcipheko yokutshisa kakhulu:

• Sebenzisa iitshaja ezicetyiswa ngumvelisi ukunqanda ukungasebenzi kakuhle kwamandla ombane kunye nobushushu obugqithisileyo.
• Gcina izixhobo phakathi kwe-20°C kunye ne-25°C (68°F–77°F); ukuphepha ukukhanya kwelanga kunye nezithuthi ezishushu.
• Qinisekisa ukungena komoya okufanelekileyo ngokugcina umoya ujikeleze izixhobo, ngakumbi ngexesha lokutshaja, kunye nokucoca iivents rhoqo.
• Susa uqhagamshelwano lwezixhobo xa luhlawulwe ngokupheleleyo kwaye uthintele ukusetyenziswa kakhulu ngelixa utshaja ukunciphisa ukugcwala kobushushu.
• Sebenzisa iisistim zolawulo lwebhetri ezijonga ubushushu; qwalasela abenzi boluvo abongezelelweyo kwizicelo ezibalulekileyo.
• Jonga rhoqo iibhetri zomonakalo, iitheminali ezicocekileyo, kwaye ugcine i-firmware ihlaziywa ngolawulo olululo lwe-thermal.

Indlela yokuphatha iBattery Overheating

Ukuba kushushu kakhulu, thatha la manyathelo:

1. Nciphisa amandla ngoko nangoko ukumisa ukuveliswa kobushushu.

2. Hambisa ibhetri kwindawo engatshiyo, nengena umoya kakuhle kude nezinto ezinokutsha.

3. Vumela ibhetri iphole ngokwendalo kwiqondo lobushushu begumbi; kuphephe ukupholisa ngokukhawuleza njengefriji.

4. Musa ukutshaja kwakhona de uphole ngokupheleleyo kwaye uhlolwe.

5. Khangela ukudumba, ukuvuza, okanye umonakalo; musa ukuphinda usebenzise ukuba yonakele.

6. Ukushisa okukhulu okanye umonakalo obonakalayo, qhagamshelana nochwepheshe.

7. Lahla iibhetri ezonakalisiweyo ngokwemigaqo yendawo; ungaze uzilahle kwinkunkuma eqhelekileyo ngenxa yeengozi zokhuseleko.

Zeziphi iibhetri ekusenokwenzeka ukuba zitshise ngokugqithisileyo?

Ayizizo zonke iibhetri ezinobungozi obufanayo bokutshisa.

I-18650 cylindrical NCM kunye neLCO iibhetri ze-lithium-ion zinovelwano ngakumbi kubushushu obugqithisileyo ngenxa yoyilo lwazo oluxineneyo lwamandla, ngakumbi phantsi kwamandla aphezulu okanye ubushushu.

I-LFP (i-Lithium yentsimbi phosphate) Iibhetri zizinzile ngokwe-thermal kwaye azifanekiseli ukutshisa kakhulu kodwa zisenobushushu obugqithisileyo kwiimeko ezigqithisileyo.

Iibhetri ezikwifomathi enkulu yeprismatic, njengezo zikwizithuthi zombane, zinokufudumala ngokugqithisileyo ngaphandle kokupholisa ngokufanelekileyo ngenxa yobukhulu bazo kunye nokuxinana kwamandla.

Kutheni iibhetri ezingasetyenziswanga Zifudumeza?

Iibhetri zinokuvelisa ubushushu naxa zingasetyenziswa ngenxa yoku:

• Ukusabela kweekhemikhali zangaphakathi: Ukuzikhupha kancinci kuvelisa ubushushu ekuhambeni kwexesha.
• Iisekethe ezimfutshane ezincinci: Iimpazamo zangaphakathi okanye ukuthotywa kubangela iisekethe ezimfutshane kunye nobushushu.
• Ukugcinwa kobushushu obuphezulu: Ubushushu bukhawulezisa ukuzikhupha kunye nokwakha.
• Ukuthotywa okunxulumene nobudala: Iibhetri ezindala zinokuxhathisa okuphezulu, zivelisa ubushushu obuninzi nangona umsebenzi omncinci.

Ngaba iibhetri ezinobungakanani obahlukeneyo zichaphazela ukuNcitshiswa kobushushu?

Ubungakanani bebhetri buchaphazela kakhulu ukutshatyalaliswa kobushushu.

Iibhetri ezinkulu zichitha ubushushu ngokufanelekileyo ngenxa yokuba ubushushu bombindi bunohambo olude, okukhokelela kubushushu bangaphakathi obuphezulu.

Uphando ibonisa ukuba iibhetri ezinomlinganiselo omkhulu we-diameter-to-height (D/H) zinamaqondo obushushu asezantsi kunye nemithamo emincinci ye-thermal ngenxa yokwanda kwendawo yokuchitha ubushushu obungcono. Oku kuchaza ukuba kutheni iipakethe ezinkulu zebhetri, njengezo zikwizithuthi zombane, zifuna iinkqubo zokupholisa ezisebenzayo, ngelixa iibhetri ezincinci ze-smartphone zisebenzisa ukupholisa okungeyomfuneko.

Uyilo lwebhetri kufuneka luthathele ingqalelo zombini ukuveliswa kobushushu kunye nokulahla ukugcina ubushushu obukhuselekileyo.

Ukuqukumbela

Ukufudumala kwebhetri yinkxalabo enkulu. Ukuqaphela oonobangela bayo kunye neempawu kunceda abasebenzisi ukuyithintela kwaye baphathe iibhetri ngokukhuselekileyo.

Ngokulawula iibhetri ngononophelo kunye nokuhlonipha imida yobushushu, sinokuyonwabela amandla aphathwayo ngelixa sinciphisa imingcipheko.
