Umngeni weBhakethi yomkhenkce! Ngaba iqondo lobushushu eliphantsi liya kunciphisa umthamo webhetri?

Kwiincwadi ezinemifanekiso ezisetyenziswa zizixhobo ezininzi zedijithali, sinokubona ubushushu bokusebenza kwemveliso, uninzi lwazo luyi-10 degrees Celsius kunye ne-40 degrees Celsius. Siyazi ukuba ibhetri ye-lithium ikhuselekile ukusebenza ngexesha lokutshaja kunye nokufudumeza, kunye ne-electrolyte ephantsi yokushisa ephantsi kobushushu obuphezulu kunye nokusingqongileyo kobushushu obuphantsi Ukuphumelela kwangaphakathi kweebhetri ze-lithium kuphantsi, okuchaphazela ukusetyenziswa kwabasebenzisi, kwaye kubangele i-low-. ukungaphumeleli kobushushu bebhetri.

Ukuba usebenzisa ezininzi iifowuni eziphathwayo okanye iibhetri ebusika obusenyakatho, unokufumanisa ukuba xa iqondo lokushisa liphantsi, ukusebenza kwebhetri kuyancipha, kwaye iimveliso zombane azikwazi ukuvulwa. Makhe sijonge ukusebenza kwebhetri kumaqondo aphantsi.

Ibhetri ebaluleke kakhulu esiyisebenzisayo ngoku ibhetri ye-lithium. Kwithiyori, isiphumo sobushushu seebhetri ze-lithium ezahlukeneyo ziyafana. Ukuze uthelekise impembelelo yeqondo lokushisa eliphantsi ngakumbi intuitively, sikhethe uvavanyo lokusebenza olunokulinganisa ibhanki yamandla.

Umbane ophathwayo ujongene novavanyo lobushushu obuphantsi

Ukuqwalasela iibhetri ezahlukeneyo ezisetyenziswa kwimithombo yamandla eshukumayo, siye saseka kwakhona imithombo yamandla ephathwayo yelithium yebhetri esetyenziswa rhoqo kwisampulu yedatha, kubandakanywa iibhetri ezithambileyo zelithium (ezaziwa ngokubanzi).

Ibhetri inobomi benkonzo ende kwiqondo lokushisa

Ukuze kube lula ukuthelekisa uthelekiso lwebenchmarking elandelayo, siqala sivavanya ukusebenza kokukhutshwa kombane ophathwayo kwiqondo lobushushu legumbi. Njengedatha yeqela lolawulo, ubushushu bendawo yokukhutshwa kweqela lolawulo yi-30 ℃.

Nceda uqaphele ukuba silapha ukuthelekisa ukusebenza kwebhetri efanayo kumaqondo okushisa ahlukeneyo. Iibhanki zamandla eebhetri ezahlukeneyo esizivavanyileyo azikalungiswa. Ngoko ke, ezi ntlobo zimbini zeeseli azinakuthelekiswa.

Igophe lokukhupha ibhetri ye-lithium ethambileyo kwindawo yobushushu begumbi

Ingabonwa ukuba i-soft-pack ye-lithium ibhetri izinzile kwindawo yokushisa kwe-30 ° C, i-voltage iyonke i malunga ne-4.95V, kunye ne-reference output energy yi-35.1 watt-yure.

I-18650 yegumbi lobushushu bebhetri ijika lokukhupha

Ibhetri ye-18650 inokuguquguquka okuncinci kwiqondo lokushisa, i-voltage iyonke iphezulu kune-4.9V, kwaye ukuzinza kulungile. Amandla emveliso yereferensi yi-29.6 watt-iiyure.

amandla eselula kwiqondo lobushushu begumbi

Inokubonwa ukuba zombini zisebenza kakuhle kakhulu kwiqondo lobushushu begumbi, kwaye ukukhutshwa okuzinzileyo kwiqondo lobushushu begumbi kunokubonelela ngesiqinisekiso sobomi bebhetri. Ewe kunjalo, oku kukwakucwangcisa kunye nokucaciswa kwesicelo samandla eselula kunye neebhetri. Isinyathelo esilandelayo kukuvavanya ukusebenza kokukhutshwa kwebhetri kumaqondo aphantsi.

indawo yokukhenkceza liqhekeza lekeyiki

0℃ bubushushu obuqhelekileyo bomxube wamanzi omkhenkce, kwaye ikwayiqondo lobushushu ekufuneka lijongwe phambi kobusika kumantla elizwe lam. Siqale savavanya ukuziphatha kokukhutshwa kombane ophathwayo kwi-0°C.

Umthombo wokuhamba kwamanzi kumxube wamanzi omkhenkce

Nangona iqondo lobushushu le-0℃ liliqondo elisezantsi le-ambient, lisengaphakathi koluhlu lobushushu obusebenzayo lwebhetri, kwaye ibhetri kufuneka ikwazi ukusebenza ngokwesiqhelo. Sibeka umbane ohambahambayo kumxube wamanzi omkhenkce, ukukhutshwa emva kokuba iqondo lokushisa lizinzile, songeza umkhenkce ukugcina ubushushu, kwaye ekugqibeleni uthumele idatha yokukhupha.

Ijika lokukhupha ibhetri ye-lithium ethambileyo kwindawo yobushushu begumbi kunye nokusingqongileyo

Ingabonwa kwi-curve yokukhutshwa ukuba i-curve yokukhupha i-soft-pack ye-lithium ibhetri ishintshile kakhulu, zonke ii-voltages kunye nexesha lokukhutshwa zincitshisiwe, kwaye amandla okukhutshwa ancitshiswe kwiiyure ze-32.1 watt.

18650 ubushushu begumbi lebhetri kunye ne-zero ye-curve yokukhupha indawo

I-18650 yokukhupha ijika ayithinteki kakhulu, kodwa i-voltage yokuqala iyanda, kodwa umthamo uchaphazeleka kakhulu, ukuya kutsho kwi-16.8 Wh.

Inokufunyanwa ukuba kwi-0 ° C, ibhetri ayichaphazeleki kancinci kwaye uluhlu lokutshintsha i-voltage alukho lukhulu, kwaye lunokunikezelwa kumsebenzisi ngokusetyenziswa ngokuqhelekileyo. Kwimeko enjalo, unikezelo lwamandla ebhetri akufanele lukhuselwe ngokukodwa.

Izinto ezikhutshwayo kwiindawo ezibandayo ziyachaphazeleka

thabatha ama-20 ngokukaCelsius yimozulu ebanda kakhulu, kwaye imisebenzi yangaphandle iyancipha kakhulu, kodwa ukusebenza kwebhetri kubaluleke kakhulu kule meko imbi. Eli liqondo lobushushu eliphantsi esilivavanye.

Ijika lokukhupha ibhetri ye-lithium ethambileyo kumaqondo obushushu ahlukeneyo

Kwi–20 ° C, ukusebenza kokukhutshwa kwebhetri ye-lithium ethambileyo kuchaphazeleka ngokucacileyo, kwaye ijika lokukhupha libonakala ngokucacileyo i-jitter.
