Iimpawu ezi-6 zoKhuseleko oluPhambili ekufuneka uzijonge xa ​​uThenga iibhetri zeVolthage ePhezulu ngo-2023

1.Ukhuseleko lwentlawulo egqithisileyo

Ukukhuselwa kwe-Overcharge kubhekiselele: iibhetri ze-lithium kwinkqubo yokutshaja, kunye nokuphakama kombane ukuya ngaphaya koluhlu olufanelekileyo, luya kuzisa ukungaqiniseki kunye nobungozi. Umsebenzi wokukhusela i-overcharge yebhodi yokukhusela kukubeka iliso kumbane wepakethi yebhetri ngexesha langempela, kwaye unqumle unikezelo lwamandla xa ukutshaja kufikelela kwi-apex yoluhlu lombane olukhuselekileyo, ukuthintela umbane ukuba ungaqhubeki nokunyuka, ngaloo ndlela udlala i-voltage. indima yokukhusela.
Umsebenzi wokukhusela umrhumo ogqithisiweyo: Xa utshaja, ibhodi yokukhusela iya kubeka iliso kwi-voltage yomtya ngamnye wepakethi yebhetri ngexesha langempela, okoko nje enye yentambo yombane ifikelela kwixabiso lokukhusela i-overcharge (i-voltage ye-default overcharge ye-ternary yi-4.25V ± 0.05 V, kunye ne-voltage ye-overcharge engagqibekanga ye-LiFePO4.75V ± 0.05V), ibhodi iya kunqumla ukunikezelwa kwamandla, kwaye lonke iqela leebhetri ze-lithium liya kumisa ukutshaja.

2.Ukhuseleko lokukhupha ngaphezulu

Ukukhuselwa kokukhutshwa ngokugqithiseleyo kubhekisela: iibhetri ze-lithium kwinkqubo yokukhupha, kunye nokuhla kwamandla ombane, ukuba wonke umbane ukhutshwe ekuphelelweni, izinto zekhemikhali ngaphakathi kwebhetri ye-lithium ziya kulahlekelwa ngumsebenzi, okubangelwa ukuhlawuliswa kumandla okanye ukuhla kwamandla. Umsebenzi wokukhusela ukukhutshwa ngokugqithiseleyo kwebhodi yokukhusela kukubeka iliso kwi-voltage yepakethe yebhetri ngexesha langempela, kwaye unqumle ukunikezelwa kwamandla xa ukhulula kwindawo ephantsi.yombane webhetri, ukuthintela umbane ukuba ungaqhubeki nokuwa, ukuze udlale indima yokukhusela.

Umsebenzi wokukhusela ukukhutshwa okungaphezulu: Xa ikhupha, ibhodi yokukhusela iya kubeka iliso kwi-voltage yomtya ngamnye wepakethi yebhetri ngexesha langempela, okoko nje enye yentambo yombane ifikelela kwixabiso lokhuseleko lokukhupha ngaphezulu (i-voltage engagqibekanga yokukhupha ngaphezulu I-ternary yi-2.7V ± 0.1V, kwaye i-voltage engapheliyo yokukhupha i-LiFePO4 yi-2.2V ± 0.1V), ibhodi iya kunqumla umbane, kwaye lonke iqela leebhetri ze-lithium liya kuyeka ukukhupha.

3.Ukhuseleko lwangoku

Ukukhuselwa kwe-Overcurrent kubhekisela: iibhetri ze-lithium kumandla ombane kumthwalo, ikhoyo ngoku iya kutshintsha ngombane kunye noshintsho lwamandla, xa umbane uphezulu kakhulu, kulula ukutshisa ibhodi yokukhusela, ibhetri okanye izixhobo. Umsebenzi wokukhusela ogqithisiweyo webhodi yokukhusela kukubeka iliso kwipakethi yebhetri ngexesha langempela ngexesha lokutshaja kunye nokukhupha, kwaye xa i-current idlula uluhlu olukhuselekileyo, luya kunqumla ukudlula kwangoku, ukukhusela i-fro yangoku.m ukonakalisa iibhetri okanye izixhobo, ukuze udlale indima yokukhusela.

Umsebenzi wokukhusela ngokugqithisileyo: xa uhlawula kwaye ukhupha, ibhodi yokukhusela iya kubeka iliso kwipakethi yebhetri yangoku ngexesha langempela, nje ukuba ifikelela kwixabiso elimiselweyo lokukhusela, ibhodi yokukhusela iya kunqumla umbane, kunye neqela lonke leebhetri ze-lithium. iyakuyeka ukutshaja nokukhupha.

4.ukhuseleko oluphezulu / oluphantsi lobushushu

Ukukhuselwa kokulawula ubushushu: Iprobe yokulawula ukushisa kwebhodi yokukhusela i-hardware idityaniswe kwi-motherboard yangaphakathi yebhodi yokukhusela kwaye ayikwazi ukukhutshwa. Iprobe yokulawula ubushushu inokubeka iliso utshintsho lobushushu bepakethi yebhetri okanye indawo yokusebenza ngexesha langempela, xa ubushushu obubekwe esweni budlula ixabiso elibekiweyo (ukungagqibekanga kokhuseleko lobushushu behardware: ukutshaja -20 ~ 55 ℃, ukukhupha -40 ~ I-75 ℃, enokutshintshwa ngokweemfuno zomthengi, kwaye umthengi akakwazi ukuyibeka yedwa), ipakethe yebhetri iya kunqunyulwa ekutshajweni nasekukhupheni, kwaye ipakethi yebhetri ingaqhubeka nokutshajwa kwaye ikhutshwe xa ubushushu buhlala. ibuyiselwe kuluhlu olufanelekileyo ukudlala indima kukhuseleko.

5.Ukukhuselwa kokulinganisa
Ukulinganisa okungahambiyo kuthetha: xa kukho ukungangqinelani kombane phakathi kweentambo zeebhetri, ibhodi yokukhusela iya kulungelelanisa umbane womtya ngamnye ukuze uhambelane ngexesha lokutshaja.irowusi.

Umsebenzi wokulinganisa: Xa ibhodi yokukhusela ibona umehluko we-voltage phakathi kwechungechunge lwebhetri ye-lithium kunye neentambo, xa utshaja, iintambo zombane ophezulu zifikelela kwixabiso lokulinganisa (ternary: 4.13V, LiFe3.525V), ukukhupha (ukutya) kunye ne-resistor elinganayo kunye yangoku malunga ne-30-35mA, kunye nezinye iintambo zombane eziphantsi ziyaqhubeka zihlawulisa. Qhubeka kude kugcwale.

6.ukhuseleko olufutshane lwesekethe (ukubona impazamo + ukukhuselwa koqhagamshelo oluchasene ne-reverse)
Isiphaluka esifutshane sithetha: isiphaluka esifutshane senziwe xa iitheminali ezilungileyo kunye nezibi zebhetri zixhunyiwe i-directly ngaphandle komthwalo. Isiphaluka esifutshane siya kukhokelela kumonakalo kwibhetri, izixhobo kunye nokunye.

Umsebenzi wokukhusela isiphaluka esifutshane: ibhetri ye-lithium ngokungalindelekanga ebangelwa yi-short-circuit (njengokuxhuma umgca ongalunganga, thatha umgca ongafanelekanga, amanzi kunye nezinye izizathu), ibhodi yokukhusela iya kuba kwixesha elifutshane kakhulu (imizuzwana ye-0.00025) , unqumle umzila we-current, ukuze udlale indima yokukhusela.
