Isishwankathelo soMgangatho

Inkcazo ngokubanzi yeSithuba-esisebenzisa iSithuba sebhethri yeLi-ion yokuGcinayabekwa phambili yiChina Aerospace Science and Technology Corporation kwaye yakhutshwa yiShanghai Institute of Space Power-Sources. Idrafti yayo ibikwiqonga lenkonzo yoluntu ukubhengeza uluvo. Umgangatho unika imimiselo kwimimiselo, inkcazo, imfuno yobugcisa, indlela yokuvavanya, ukuqinisekiswa komgangatho, iphakheji, ukuthutha kunye nokugcinwa kwebhetri yokugcina i-Li-ion. Umgangatho uyasebenza kwindawo-esebenzisa i-li-ion yokugcina ibhetri (apha ekubhekiselwa kuyo njenge "Ibhetri yokuGcina").

Imfuneko yoMgangatho

Imbonakalo kunye namanqaku: Imbonakalo kufuneka ibonakale; umphezulu kufuneka ucoceke; amalungu kunye namacandelo kufuneka agqibelele. Kufuneka kungabikho ziphene kumatshini, kungabikho ezongezelelweyo kunye nezinye iziphene. Ukuchongwa kwemveliso kuya kubandakanya ipolarity kunye nenombolo yemveliso elandelekayo, apho ipali evumayo imelwe ngu “+” kwaye ipali egxekayo imelwe ngu “-“.

Imilinganiselo kunye nobunzima: imilinganiselo kunye nobunzima kufuneka buhambelane neenkcukacha zobugcisa bebhetri yokugcina.

Ukungangeni moya: izinga lokuvuza kwebhetri yokugcina ayikho ngaphezu kwe-1.0X10-7Pa.m3.s-1; Emva kokuba ibhetri iphantsi kwe-80,000 yemijikelo yobomi yokudinwa, i-welding seam yeqokobhe akufuneki yonakaliswe okanye ivuze, kwaye uxinzelelo olugqabhukileyo alufanele lube ngaphantsi kwe-2.5MPa.

Ngeemfuno zokuqina, iimvavanyo ezimbini ziyilelwe: izinga lokuvuza kunye noxinzelelo lokuqhuma kwegobolondo; Uhlalutyo kufuneka lube kwiimfuno zovavanyo kunye neendlela zovavanyo: ezi mfuno ziqwalasela ubukhulu becala izinga lokuvuza kweqokobhe lebhetri phantsi kweemeko zoxinzelelo oluphantsi kunye nokukwazi kwayo ukumelana noxinzelelo lwerhasi.

Ukusebenza kombane: ubushushu be-ambient (0.2ItA, 0.5ItA), ubushushu obuphezulu, amandla obushushu obuphantsi, ukuhlawuliswa kunye nokukhupha ukusebenza kakuhle, ukumelana kwangaphakathi (AC, DC), umthamo wokugcinwa ohlawulisiweyo, uvavanyo lwe-pulse.

Ukuziqhelanisa nokusingqongileyo: ukungcangcazela (i-sine, i-random), ukothuka, isifunxa se-thermal, ukukhawulezisa okuzinzileyoXa kuthelekiswa neminye imigangatho, i-vacuum ye-thermal kunye namagumbi okuvavanya amanqanaba okukhawuleza okukhawulezileyo anemfuno ekhethekileyo; ukongeza, ukukhawuleza kovavanyo lwempembelelo kufikelela kwi-1600g, okuyi-10 amaxesha okukhawuleza komgangatho oqhelekileyo osetyenziswayo.

Ukusebenza koKhuseleko: isiphaluka esifutshane, i-overcharge, i-overdischarge, i-over-temperature test.

Ukuchasana kwangaphandle kovavanyo olufutshane lwesekethe akufanele kube ngaphezu kwe-3mΩ, kwaye ubude be-1min; uvavanyo lwe-overcharge lwenziwa kwimijikelezo ye-10 yokuhlawula kunye nokukhupha phakathi kwe-2.7 kunye ne-4.5V yangoku ecacisiweyo; i-overdischarge iqhutyelwa phakathi kwe--0.8 kunye ne-4.1V (okanye ixabiso elimiselweyo) kwi-10 imijikelezo yokutshaja kunye nokukhupha; uvavanyo lobushushu obugqithisileyo kukuhlawulisa phantsi kweemeko ezichaziweyo ze-60℃±2℃.

Ukusebenza kobomi: I-Low Earth Orbit (LEO) yokusebenza komjikelezo wobomi, i-Geosynchronous Orbit (GEO) yokusebenza komjikelezo wobomi.

Izinto zovavanyo kunye nobungakanani besampulu

Isiphelo & Uhlalutyo

Ibhetri yeLithium isetyenziswa ngokubanzi kuphapho, kwaye inemigangatho ehambelanayo nemimiselo phesheya, umz. DO-311 series standard ekhutshwe yiAmerican Airline Wireless Technical Committee. Kodwa lixesha lokuqala ukuba iTshayina iseke umgangatho welizwe kule ndawo. Inokuthi imveliso kunye nokuveliswa kweebhetri zeLithium kwinqwelomoya iya kuvulelwa amashishini ngokubanzi. Kunye nokukhula ngakumbi kwesiphekepheke esiqhutywa ngumntu, umzamo we-aerospace uya kukhula kwicala lentengiso. Ukuthengwa kwezixhobo ze-aviation spare kuya kuba yintengiso. Kwaye ibhetri ye-lithium, njengenye yamacandelo, iya kuba yenye yeemveliso ezithengiweyo.

Ngokuphathelele ukhuphiswano olumandla kuzo zonke iindlela zobomi malunga nebhetri ye-lithium namhlanje, kubalulekile ukufumana umda wokukhuphisana ekumakisheni kwicala elitsha kunye nophando kwintsimi entsha kwangoko. Ishishini liqala ukuqwalasela uphuhliso lwebhetri ye-aerospace inokubeka isiseko esiluqilima kuphuhliso lwalo lwexesha elizayo.
