Kungani ibhethri le-lithium-ion elinamandla alinganiselwe angu-100Ah ngezinye izikhathi linikeza amandla angu-70Ah kuphela ngesikhathi sokusebenza? Imbangela eyinhloko yalokhu kushoda kwamandla akuvamile ukuba ukwehluleka kwesakhiwo okubi kakhulu; kunalokho, cishe njalo kubangelwa ukungalingani kwamandla kagesi angaphakathi phakathi kwamaseli ngamanye. Njengoba nje i-stave emfushane kakhulu emgqonyeni wokhuni inquma inani lamanzi elingabamba, iseli elibuthakathaka kakhulu ohlelweni lochungechunge linquma amandla angasetshenziswa yilo lonke ibhethri. Lapho umehluko we-voltage phakathi kwamaseli udlula u-30mV, izindlela zokulinganisela ezijwayelekile ezihlanganisiwe ku-standard Battery Management Systems (BMS) azinawo amandla wamanje okulungisa ukuhlukahluka. Ngaphansi kwalezi zimo, i-equalizer yebhethri ekhethekile iba ithuluzi elihle kakhulu lokulungisa ukungalingani kwamaseli ebhethri. Ukuze kuxazululwe le nselele yokusebenza,I-Chengdu Heltec Energy Technology Co., Ltd.Ihlinzeka ngobuchwepheshe bokulinganisela obuthuthukisiwe kanye namathuluzi okulungisa aklanyelwe ukukhomba nokulungisa amaseli angahlelekile kahle, ukuvula umthamo onqunyelwe, nokubuyisela iphakethe lebhethri emazingeni alo okusebenza aklanywe ngendlela ehlelekile.
Imikhawulo Yokusebenza Yokulinganisela Okungasebenzi Ekunakekelweni Nokulungiswa
Izinhlelo zokulinganisela ezijwayelekile ezingasebenzi zisebenza ngokukhipha amandla amaningi avela kumaseli ane-voltage ephezulu njengokushisa ngokusebenzisa ama-shunt resistors. Nakuba lo mklamo wanele ukugcina amaseli aphilile, ahambisana kahle ngesikhathi sokusebenza okujwayelekile, awubonakali unele lapho umehluko we-voltage udlula u-50mV noma lapho amaseli amadala exutshwa namasha ngesikhathi sokwakhiwa kabusha kwephakethe eliyingxenye. Ukulinganisela okungasebenzi kusebenza kuma-currents aphansi kakhulu, ngokuvamile phakathi kuka-30mA no-100mA, okusho ukuthi ukuxazulula ukuhlukana okukhulu kwamandla kuma-pack ane-high capacity kungathatha izinsuku, uma kungenjalo amasonto.
Ukuze kuxazululwe lokhu kungalingani okukhulu, izindawo zokulungisa zobungcweti zisebenzisa amathuluzi akhethekile okulungisa kunokuthembela kuhadiwe yangaphakathi ejwayelekile. I-Chengdu Heltec Energy Technology Co., Ltd. ibhekana nale nselele yemboni ngobunjiniyela obusebenza kanzimaisilinganisi sebhethriamathuluzi ahlanganisa ukulinganisa okunembile kwamandla kagesi, ukuxilongwa kokumelana kwangaphakathi, kanye nokudluliswa kwamandla kagesi aphezulu. Esikhundleni sokuchitha amandla njengokushisa, lawa ma-equalizer okulungisa akhipha amandla kumaseli ane-voltage ephezulu kakhulu futhi awasabalalise ngqo kumaseli ane-voltage ephansi kakhulu, alungise ukuhlukana okukhulu kwamaseli ngaphakathi kwesikhathi sokusebenza esingokoqobo.
Imininingwane Yobuchwepheshe kanye Nokwakhiwa Kobunjiniyela
Ukunemba kwehadiwe yokulungisa ekhethekile kuncike ngqo ekwakhiweni kokulawula kanye nesisombululo sokulinganisa sohlelo. I-Heltec Energy yakha amathuluzi ayo okuxilonga nokulungisa isebenzisa amayunithi amakhulu (ama-MCU) asheshayo, avela ku-Microchip Technology Inc. Lawa maprosesa avumela ukutholwa kwamandla kagesi ngesikhathi sangempela kuwo wonke amaseli ngamanye anobubanzi bokulinganisa obungu-1V kuya ku-5V ngeseli kanye nesilinganiso sokunemba esingu-±1mV. Uhlelo lokulawula lwangaphakathi luhlonza ngokuzenzakalelayo ukucushwa kwamaphakethe ebhethri axhunyiwe, lusekela ukucushwa kusukela ku-2S kuya ku-24S, ngamamodeli athile athuthukile anweba amakhono afinyelela ku-32S. Lolu hlobo lwe-multi-chemistry luvumela ithuluzi elilodwa ukuthi lisevise amakhemikhali e-Lithium Nickel Manganese Cobalt Oxide (NCM), i-Lithium Iron Phosphate (LFP), kanye ne-Lithium Titanate (LTO) ngaphandle kokudinga ukulinganiswa kabusha kwesakhiwo ngesandla.
Umsebenzi oyinhloko wokwelapha wemishini uncike endleleni yokulinganisela amandla nokudlulisa amandla enikeza ugesi oqhubekayo wokulinganisa ofika ku-15A noma ku-25A kuye ngokwakhiwa kwemodeli ethile. Ngokungafani namabhodi okulinganisela asebenzayo ayisisekelo lapho ugesi ophuma khona ugesi uyancipha njengoba ama-voltage eseli ehlangana, amathuluzi e-Heltec Energy agcina ugesi ozinzile, ophakeme osebenza ngokuzimela ngaphandle kwegebe lamandla. Ochwepheshe bangakhetha ezindleleni ezintathu zokusebenza nge-interface: ukulinganisa ngesandla, ukulinganisa okuzenzakalelayo, noma ukulinganisa okusizwa ukushaja. Ukwakhiwa okungokoqobo kufaka phakathi iphaneli yokulawula enelungelo lobunikazi elungisa phakathi kwama-degree angu-0 no-45 ukuze ihambisane nezindawo zokusebenza ezimile noma ezihleli, isikhombikubona sokuthinta esigcwele esingu-7 intshi, kanye nenkinobho yokumisa ephuthumayo ebonakalayo.
Ukuze kuphephe ngesikhathi sokudluliselwa kwamandla ane-amperage ephezulu, i-circuitry ifaka phakathi ukuvikelwa kwe-overvoltage yeseli elilodwa kanye nezixwayiso zehadiwe zesikhathi sangempela ze-reverse polarity, i-total pack overvoltage, izimo ze-undervoltage, kanye ne-internal metal-oxide-semiconductor field-effect transistor (MOSFET). Ukulungiswa okuphezulu, njengemodeli ye-HT-CJ32S25A, kufaka phakathi izibonisi ze-liquid-crystal (LCD) ezikwibhodi ukuze zibonise ama-voltage e-string ngamanye, i-cumulative pack voltage, i-active balancing current, kanye namazinga okushisa angaphakathi kanye nokuxhumeka kohlelo lokusebenza lwe-Wi-Fi oluhlanganisiwe ukuze kulondolozwe idatha ekude.
Izimo Zokusebenza Ekukhiqizeni Nokulungisa Amabhethri Esimanje
Ukufakwa kwezinsimbi zokulungisa zamandla aphezulu kuhlukaniswe ngezigaba ezintathu ezihlukene zemakethe, ngayinye iveza izakhiwo zephakethe ezihlukile kanye nezidingo zokusebenza:
1. Ukuthutha Okuncane kanye Nomuntu Siqu
Izimoto zikagesi ezilula, njengezikuta zikagesi, izimoto zokuhamba zomuntu siqu, kanye nezinqola zegalofu, ngokuvamile zisebenzisa ukwakheka kwebhethri okuqinile nokuqinile. Lapho lezi zimoto zibhekana nokuwohloka kobubanzi, abahloli bomthamo ophathekayo kanye nama-equalizer asebenzayo afakwa endaweni. Ithuluzi lihlose amamojula anomthamo omncane, lihlukanise amaseli anokumelana okuphezulu futhi lilinganise iphakethe ngaphakathi kwezimo zokulungisa insimu ngaphandle kokudinga ukuthunyelwa kwephakethe eliphelele esikhungweni esiphakathi.
2. Izimoto Zezentengiselwano kanye nama-EV Abagibeli
Abaqhubi bezimoto, izinsizakalo zezimoto ezihlanganyelwayo, kanye nama-workshop okulungisa izimoto abhekana namamojula ebhethri ane-voltage ephezulu, anomthamo omkhulu. Kulezi zinhlelo zokusebenza, abahloli be-benchtop charge/discharge bahambisana nezinhlelo zokulinganisela ezisebenzayo ze-modular. Ochwepheshe basebenzisa imijikelezo yokuqinisekisa umthamo ogcwele, besebenzisa izindlela zokulinganisa ezijulile ukulungisa ukuhlukahluka kweseli kuya kweseli okubangelwa izindawo zokushisa ezingalingani ezitholakala ngaphakathi kwezimoto ezingaphansi kwezimoto.
3. Izinsiza Zikagesi Zezimboni kanye Nokugcinwa Kwamandla Okulinganiselwe Kwegridi
Izilungiselelo zokugcina amandla ezindlu, iziteshi zokuxhumana, kanye nezikhungo zamandla elanga zithembele kuma-array amakhulu, aneziteshi eziningi. Ukungalingani kulezi zindawo kunganciphisa imbuyiselo yezezimali ekutshalweni kwezimali kwezinhlelo zamandla avuselelekayo. Izinhlelo zokulungisa iziteshi eziningi zisetshenziselwa ukwenza ukusebenza kwamaseli okujikeleza kanye nokulinganisa kwamandla aphezulu kuwo wonke amaphakethe amakhulu, ukubuyisela ukuhambisana kwesistimu kanye nokuzinzisa ingqalasizinda yamandla okusekelayo ezimbonini.
Ukuthuthukiswa Kokusebenza kanye Nokwandiswa Kokuphila
Ngokuhlanganisa ukuhlolwa kokuxilonga nokusabalalisa kabusha kwamandla asebenzayo, amathuluzi okulinganisa akhethekile ashintsha indlela impilo yebhethri ephathwa ngayo ezindaweni zokusebenzela zobungcweti. Ukulungisa ukulungiswa kwamandla eseli kuya ekubekezeleleni kwe-1mV kuvimbela ngqo amaseli ngamanye ukuthi angafinyeleli emikhawulweni yawo yokunqunywa kwamandla ephansi noma aphezulu ngaphambi kwesikhathi. Lokhu kulungiswa kokulinganisela kusiza abahlinzeki bezinto zokuthutha, ukulungisa amanethiwekhi engqalasizinda, kanye nezindawo zokukhiqiza ukuthi zibuyise umthamo wephakethe olahlekile, ukwehlisa izindleko zewaranti eziphelele, futhi kuqinisekiswe ukuzinza okuqhubekayo kwezinhlelo zokugcina amandla. Ukukhetha ukusethwa kokulinganisela okulungile ngokusekelwe kumakhemikhali athile eseli kanye nokucushwa kochungechunge kuvumela opharetha ukuthi balondoloze izimpahla zehadiwe futhi bandise isikhathi sokusebenza samaphakethe ebhethri e-lithium ezimbonini.
