I-Watma ibihlola ukusetshenziswa kwesibili kwebhethri lamandla e-lithium-ion ngo-2012, esebenzisa ibhethri le-lithium-ion lamandla emoto kagesi eselathatha umhlalaphansi, futhi yakha isiteshi samandla okugcina amandla ebhethri ye-lithium iron phosphate ion engu-3MW. Ngokufanayo, kusukela ngo-2012 Qala ukutshala imali kumabhethri we-yuan amathathu. Ngokusho kokuthuthukiswa kwezimoto ezintsha zamandla, kulinganiselwa ukuthi ngo-2020, izimoto zikagesi ezihlanzekile kanye nezimoto ezihlanganisiwe ze-plug-in sezifinyelele ezigidini ezimbili, ezinamayunithi angaphezu kwezigidi ezingu-5.

Ngaphansi kwesikhala esikhulu sokwenyuka, ngokuphela kokuphila kwebhethri ye-lithium-ion, ibhethri ye-lithium ion yamandla emotweni kagesi izofakwa enombolweni enkulu, ukuthi la mabhethri abhekana kanjani nenkinga enkulu ebhekene nemboni, kanye Ihlelwa kanjani i-Watma? Uhlelo lokugaywa kabusha kwebhethri sekuyisikhathi eside liyisekela lomphathi jikelele we-Shenzhen Watma Battery Co., Ltd. (I-Institute Dean) u-Rao Minmin uthe ekwethulweni kwenethiwekhi yokuqala kagesi, empeleni, i-Watma isivele ihlole i-lithium enamandla ngo-2012.

Umzila, indlela yebhethri ye-ion, usebenzisa ibhethri yemoto kagesi esele umhlalaphansi i-lithium-ion, yakha isiteshi samandla okugcina amandla ebhethri ye-lithium iron phosphate ion, yabeka isisekelo sokuhwebelana kwebhethri yokugcina amandla kadoti. Ngasikhathi sinye, i-Watma iphinde yathuthukisa ngamandla imikhiqizo yokugcina amandla ohlelweni lokuphusha amabhethri emoto yamandla e-lithium-ion entsha. Ngaphezu kokuthuthukiswa kwesiteshi samandla okugcina amandla, i-Watma iphinde yathuthukisa ngempumelelo i-tram yokugcwalisa engu-1200kwh, 750kwh, 640kWh (esetshenziselwa izimoto zikagesi, umthamo wokugcina amandla, njll.

). Ngokuzayo, kucatshangelwa ukuthi kusetshenziswe amabhethri e-lithium-ion ashukumisayo ezimotweni ezengeziwe zeselula, futhi kuphinde kuhlolwe ukusetshenziswa kwamandla kadoti amabhethri e-lithium ion ohlelweni lokugcina amandla. Ngakolunye uhlangothi, i-Watma izosebenzisa ubuchwepheshe obuthuthukisiwe bokukhiqiza, i-short-range, ukugaywa kabusha okusebenzayo kwezinto ezifana ne-nickel, i-cobalt, i-manganese, i-lithium ebhethri, bese ngokusebenzisa imodeli yokuqala yenkampani "yokujikeleza kwe-directional" kanye ne-"reverse product positioning design" ehamba phambili emhlabeni, lungisa ingxenye ye-multi-elementi ye-elementi ngokufanisa kabusha i-synthetic, ukuhlanganiswa kwe-synthetic kanye ne-synthetic technology. "ukujikeleza kokuqondisa" kusuka ebhethri elilahlwayo kuya entweni yebhethri, ngaleyo ndlela kukhiqizwa ibhethri kusuka ekukhiqizeni, ukusetshenziswa kuya ekutholeni ukujikeleza kwawo wonke ukuhlanganiswa kwe-Organic.

Icabangela ukuphepha kwebhethri kanye nokuhlolwa kokuminyana kwamandla kobuchwepheshe bebhethri obungama-yuan amathathu kusukela ngo-2008, i-Watma iqongelele iminyaka engaphezu kwengu-7 yokuhlangenwe nakho okuhlobene nokusebenza kwemoto yamandla, ifakwe ibhethri le-Watma elingaphezu kuka-30,000 isethi yaseTaiwan, i-operation mileage ingu-430,000 km. Mayelana nokushajwa okusheshayo kwebhethri, ibhethri ye-ion ye-Watema phosphate nayo ishajwe imizuzu eyi-10 ukuze ishaje amandla angu-80%, futhi isetshenziswe ebangeni elikhulu. Okufanayo kusekelwe ekuphepheni, okuyisisekelo kwamanje zonke izinto eziyisisekelo ze-Watma yibhethri ye-ion ye-lithium yensimbi, kodwa ngokwezinto zokwakha zama-yuan amathathu, u-Rao Minmin uthe inzuzo yokuminyana kwamandla empeleni yi-Watma.

Kusukela ngo-2012, ngaqala ukutshala imali ocwaningweni nasekuthuthukisweni iminyaka eminingi, kodwa angizange ngikhuthaze kabanzi, futhi ngizoba nezinhlobo eziningi zokuthuthuka. Ngokufanayo, waphinde wathi i-Watma isebenzisa izinto eziyinhlanganisela njenge-electrode esebenzayo nenegethivu yebhethri ukuze ithuthukise ukuminyana kwamandla ebhethri cishe ngama-20%. Njengamanje, umthamo wamandla webhethri we-Watema phosphate ion monomer ungafinyelela ku-180-200 kWh / kg, u-100KWH / kg ungafinyelelwa ngemva kokusetha ibhethri.

Mayelana nokuphepha, ibhethri ye-lithium-ion yamandla ka-Watema ekhiqizwa ku-monomer, imojula kuya ohlelweni lokuqoqa kuze kube yilapho umsebenzi ofakiwe, yakha uhla olugcwele lokutholwa, ngokusebenzisa isiteji esikhulu sedatha, ukuqapha imoto ngayinye. Njengamanje, i-Watma cylindrical ferric lithium ion ibhethri isakhiwo sethula ithubhu yesikhungo sokungenisa umoya sokujoyina, ukuxazulula inkinga yebhalansi yokucindezela kwangaphakathi kwebhethri, kuvimbela ukuqhuma kwebhethri; amavalvu okuvikela amasha ekepisi elihlanganisiwe, ukulawula ngempumelelo umfutho wangaphakathi webhethri ngokuphepha okuvamile Phakathi kwevelu yobubanzi, vimbela ingozi yokuqhuma; iphakethe lebhethri lisebenzisa amaphaneli ayinhlanganisela aklanywe ngokukhethekile namasekhethi okuvikela e-PCB, ngisho noma indawo yokusebenzisa ibhethri ivumela wonke amabhethri endaweni efanayo, ngisho nokulinganisela kwandisa ukumelana nokwenza ibhethri. Umthwalo othwelwayo uyafana, futhi kunomehluko wemvelo phakathi kwebhethri.

Ngaphezu kwalokho, ibhethri le-Watma lokushisa eliphansi aliphumelelanga kuphela e-Xinjiang Urumqi, kodwa selidlulile igunya loMnyango Wezimboni Zolwazi we-Chemical Physics Power Product Quality Supervision and Inspection Center, okubonisa ukuthi isifunda esisenyakatho yezwe lami sikhuthaza izimoto zikagesi ezihlanzekile zinesixazululo sokuqala sobuchwepheshe. Ukunqamula umkhawulo wokushaja kanye nokukhipha okungaphansi kwamadigri angu-20 ngaphezu kweziro, kungabonakala ngokukhipha okujwayelekile okungu-35 degrees kanye noziro okungu-20 degrees ukushaja okuvamile. Ekugcineni, lapho ngikhuluma ngezinga elisha lebhethri kazwelonke, uRao Dingyi ukholelwa ukuthi ukuqaliswa kwezinga elisha lezwe liye lanezela izinga lokushisa eliphezulu nokushisa okuphansi kanye nokucwiliswa kwemodyuli yebhethri yebhethri, empeleni, lokhu kuthuthukisa izinga lokufinyelela kwebhethri, Isidingo Sokuphepha kwebhethri.

Kodwa ukuthuthukiswa okunempilo kwemboni nakho kunenzuzo, futhi ukusetshenziswa kokulinganisa kwemboni nakho kukhulu kakhulu.
