Chii Chinonzi Kudzika Kwekuburitsa?
Hudzamu hwekuburitsa iperesenti yehuwandu hwawaburitsa mubhatiri. Kana iwe ukatanga zvizere uye uchimhanyisa kudzika kusvika pa20%, ndiyo 80% DoD. Nyore zvakakwana.
Chikonzero icho chero munhu ane hanya nenhamba iyi hupenyu hwekutenderera. Yese bhatiri dhatabheti inokupa iwe kutenderera chiyero, asi iyo chiyero hairevi chinhu pasina kuziva iyo DoD iyo yakaedzwa pairi. Sero rakatemerwa 4000 cycles pa 50% DoD rinogona kungokupa 1200 cycles kana urikumhanyisa kuti ipere nguva dzese. Ndakaona maprojects achipiswa neizvi. Mumwe munhu anofungidzira sisitimu yakavakirwa pamusoro wenyaya kutenderera nhamba pasina kuverenga yakadhindwa, uye makore maviri gare gare iyo paki ndeye toast.
Iyo Tradeoff Hapana Anoda Kutaura Nezvayo
Hechino chinhu. Kudzika bhasikoro kunowedzera hupenyu, asi zvakare zvinoreva kuti uri kubhadharira huwandu hwausingambo shandisa. A 100 kWh system inogumira ku60% DoD inokupa 60 kWh per cycle. Ungadai wakatenga paki diki womhanya zvakanyanya. Kunyangwe izvo zvine musoro zvinoenderana nemitengo yesero, mutengo wekutsiva, zvipingaidzo zvesaiti, uye zvimwe gumi neshanu zvimwe zvinosiyana. Hapana mhinduro yakarurama.
Masero eLFP akachinja masvomhu pane izvi. Makore mashanu apfuura, kumhanya NMC kuenda ku90% DoD kwaive kubvunza dambudziko. Rutivi rwe cathode runoparara. Kurasikirwa neokisijeni, kuparara kwechimiro, vese vanombofungirwa. LFP haina idzo nzira dzekutadza paDoD yakakwira. Unogona kusundidzira zvakanyanya pasina chirango chimwe chete. Ndosaka akawanda emapurojekiti ekuchengetedza akamira kuLFP kunyangwe kuwanda kwesimba kuri kushata.
Chii Chinouraya Masero paHigh DoD
Rutivi rweanode runosimbiswa kumativi ese maviri enzvimbo yekuchaja hwindo. Pasi pedyo ne zero, uri kudhonza lithium kubva mugirafu iyo inoda chaizvo kubatirira pairi. Iyo SEI layer inotsemuka uye inogadziridza. Pese painochinja, inodya yakawanda lithium uye simba rinodonha. Kusvika padyo ne100%, kunyanya pakukurumidza kuchaja, unoisa panjodzi yekuputira. Hapana kunyanyisa kwakanakira hupenyu hurefu.
Cathode degradation inoenderana zvakanyanya nemakemikari. NMC111 yakatsiga kupfuura NMC811 pahigh voltage, asi NMC811 inokupa kuwanda kwesimba. Iyo yakakwira-nickel cathodes inoda kuburitsa mweya weokisijeni paunodzidenha kupfuura imwe nzvimbo. Okisijeni iyoyo inopindirana ne electrolyte uye inogadzira kupisa. Ramba uchiita izvozvo uye sero rinokura nekukurumidza.
Mechanical stress inonyanya kukosha kupfuura zvinofungwa nevanhu vazhinji. Graphite inozvimba kana iwe uchiiita. Silicon anodes inowedzera kuwedzera. Kudzika bhasikoro kunoreva shanduko huru yevhoriyamu, kushushikana kwakawanda pamagetsi emagetsi, mukana wakawanda we delamination kana kuputika kwechidimbu. Mamwe masilicon matsva-blend anode ane matambudziko chaiwo neizvi.
Maitiro Anobata sei DoD Limits
Yese bhatiri manejimendi system ine min uye max SoC setpoints. Iyo BMS haikusiye iwe kubuda kunze kwehwindo iro. Zvinoshevedzwa nemutengi "0%" pachiratidziro chavo pamwe 5% kana 10% chaiyo SoC. Yavanodaidza kuti "100%" inogona kunge iri 95%. Vagadziri vanoita izvi kuti vavake mumucheto.
Dambudziko nderekuti kugona kunopera nekufamba kwenguva. Sero rakatanga pa100 Ah rinogona kunge riri pa85 Ah makore matatu gare gare. Kana BMS yako ichiri kushandisa iyo yekutanga kukosha kukosha, yako DoD kuverenga haina kururama. Masisitimu akanaka anodzokororwa nguva nenguva. Cheap masisitimu haadaro.
Tembiricha inokanda chimwe chipanera mukati. Sero pa 0℃rinogona chete kuburitsa 60% yehuwandu hwayo yakayerwa kunyangwe ukaedza kudhonza 100% DoD. Iyo lithium haigone kufamba nekukurumidza zvakakwana. Mamwe masisitimu anobvisa muganho weDoD otomatiki kana kuchitonhora. Vamwe vanongokurega iwe uchiedza wokundikana.
Zvandinoudza Vatengi
Yekuchengetedza grid, 80% DoD yakanaka mwero. Iwe unowana kushandiswa kwakanaka pasina kuuraya maseru. Revenue stacking applications inoda ma cycles akawanda pazuva inogona kuenda ku70% kuchengetedza hupenyu. Simba rekuchengetedza iro rinogara risingaite nguva zhinji rinokwanisa kuwana 90% kana kukwira pazviitiko zvisingawanzo kudiwa.
Nzvimbo dzekugara dzezuva rinowanzoita 80-90%. Iyo Tesla Powerwall inomhanya pedyo ne100% inogona kushandiswa, asi ivo vari kushandisa masero avo uye yavo waranti math. Vasanganisi vebato rechitatu vanowanzove vanochengetedza.
EVs ari pese pamepu. Iyo inoratidzwa 0-100% padashboard yako haienderane neinoganhurwa yesero. Vagadziri vanovanza huwandu pamativi ese ari maviri. Zvakawanda sei zvinoenderana nedhizaini yepakiti uye nehukasha fungidziro yavo yewaranti.
Chinokosha ndechekuti DoD isarudzo yekugadzira, kwete nhamba yakatarwa. Iwe unozvitora zvichibva pahupfumi, kushivirira njodzi, uye zvinodiwa zvekushandisa. Chero ani anokuudza kuti pane imwe mhinduro chaiyo kune ese mamiriro haana kuita mapurojekiti akakwana.
