Bubuphi ubunzulu bokukhutshwa kweebhetri ze-lithium-ion kunye nendlela yokuyiqonda?

Kukho iithiyori ezimbini malunga nobunzulu bokukhutshwa kweiibhetri ze-lithium. Enye ibhekisa kwindlela ehla ngayo i-voltage emva kokuba ibhetri ikhutshwe kangangexesha elithile, okanye ingakanani i-terminal voltage (ngelo xesha ikhutshwayo ngokubanzi). Enye ibhekisa kumthamo webhetri, ekuthi yimalini intlawulo ekhutshiweyo.

Ibhetri yeLithium-ionubunzulu bokukhutshwa, izinto ezithintela ubunzulu bokukhutshwa kweebhetri ze-lithium-ion.Ekubeni ibhetri ye-lithium-ion ihlawuliswa, kufuneka ikhutshwe. Ngokwethiyori, inkqubo yokukhutshwa kweebhetri ze-lithium-ion ilinganisiwe. Xa ukhupha, ingqalelo kufuneka ihlawulwe kwisantya kunye nobunzulu bokukhutshwa. Ubunzulu bokukhutshwa ngumlinganiselo wexabiso elikhutshiweyo kumthamo we-nominal, owumlinganiselo wexabiso elikhutshiweyo kwinani elipheleleyo lokugcina (umthamo oqingqiweyo). Okukhona lisezantsi inani, kokukhona ukuqukuqela kusezantsi. Ubunzulu bokukhutshwa kwebhetri ye-lithium-ion ihambelana ngokusondeleyo kwi-voltage kunye ne-current, kwaye ingabonakaliswa ngokwemiqathango yombane kwaye ibonakaliswe ngokuhambelana nangoku.

Ubunzulu bokukhutshwa kweebhetri ze-lithium-ion yi-80%, oku kuthetha ukuba bakhutshwe kwi-20% eseleyo yomthamo wabo.

Ubunzulu bokukhutshwa buchaphazela ibhetri ngolu hlobo lulandelayo: ukukhutshwa okunzulu, kulula kwaye kufutshane ubomi bebhetri ye-lithium-ion; omnye umba kukusebenza kwigophe lokuhamba. Ubunzulu bokukhutshwa, ukungazinzi kwe-voltage kunye nekhoyo. Ngexesha elifanayo lokukhutshwa, ixabiso le-voltage liphantsi, ubunzulu bokukhutshwa. Imisinga emincinci ikhupha ngokupheleleyo. I-low yangoku, ixesha elide lokugijima kunye nentlawulo encinci kwi-voltage efanayo. Isishwankathelo, nasiphi na isihloko malunga nokukhutshwa kweebhetri ze-lithium-ion kufuneka siqwalasele inkqubo yokukhupha kwaye, ngokubalulekileyo, okwangoku.

Umbane weebhetri ze-lithium-ion wehla kancinci njengoko ibhetri ikhutshwa.

Ngokomzekelo, xa ibhetri ikhutshwe ukuze igcine i-80% yomthamo wayo, kodwa ibhetri yayihlawulwe ngokupheleleyo kwi-4.2V, ngoku ilinganiswa kwi-4.1V (nantsi umzekelo woqikelelo lokubhekisela kuphela, ixabiso liya kuhluka iibhetri zomgangatho owahlukileyo kunye nokusebenza).

Xa ibhetri ye-lithium-ion ithatha amandla kuso nasiphi na isixhobo, ukuxhathisa kwangaphakathi kwebhetri kuyenyuka njengoko umthamo uyancipha.

Xa ubunzulu bokukhutshwa bukhulu, ukuchasana kuyanda kwaye ikhoyo ngoku iqhubekayo, efuna amandla amaninzi kwibhetri kwaye iyichithe ngendlela yokushisa.

Enye into ezinzileyo yokukhupha ijika yeebhetri ze-lithium-ion inokutshintsha ngokuphawulekayo xa ubunzulu bokukhutshwa bukhulu.

Ke ngoko, ukukhawulela ubunzulu bokukhutshwa kuluhlu oluthe tyaba luya kuvumela abathengi ukuba babe nolawulo olungcono lwamandla kunye namava angcono kwizicelo zabo.

Yintoni omawuyijonge xa ​​ukhupha aibhetri ye-lithium-ion. Ukukhupha ibhetri ye-lithium-ion ngokwenene malunga nokuchonga izinto ezichaphazela ukukhutshwa kwebhetri ye-lithium-ion. Into ebalulekileyo kukwenza imisebenzi efanelekileyo xa ukhupha, nto leyo eya kuba negalelo kwibhetri ehlala ixesha elide.

Ukukhutshwa kwe-lithium ion nzulu, ilahleko enkulu yebhetri. Okukhona ibhetri ye-Li-Ion igcwaliswe ngokupheleleyo, kokukhona ilahleko yebhetri inkulu.Iibhetri zeLi-ion kufuneka zibekwimo ephakathi yokuhlawula, apho ubomi bebhetri bubude kakhulu.
