Lingaliro la Lithium charge and discharge & mapangidwe a njira yowerengera magetsi

2.4 Dynamic voltage algorithm magetsi mita

The dynamic voltage algorithm coulometer imatha kuwerengera kuchuluka kwa batire ya lithiamu molingana ndi mphamvu ya batri.Njirayi imayerekezera kuchuluka kapena kutsika kwa mtengo wamagetsi malinga ndi kusiyana pakati pa mphamvu ya batri ndi mphamvu ya batire yotseguka.Zambiri zamagetsi zamagetsi zimatha kutsanzira bwino momwe batire ya lithiamu imakhalira, kenako kudziwa SOC (%), koma njirayi siyingayerekeze kuchuluka kwa batire (mAh).

Njira yake yowerengera imatengera kusiyana kwamphamvu pakati pa voteji ya batri ndi voteji yotseguka, pogwiritsa ntchito njira yobwerezabwereza kuwerengera kuchuluka kulikonse kapena kuchepa kwa chiwongola dzanja, kuti muyerekeze kuchuluka kwa ndalama.Poyerekeza ndi yankho la coulomb metering, ma voltage algorithm coulometer sangaunjike zolakwika ndi nthawi komanso zamakono.Coulometric coulometer nthawi zambiri imakhala ndi kuyerekezera kolakwika kwa mtengo wake chifukwa cha zolakwika zapanthawi yozindikira komanso kudziletsa kwa batri.Ngakhale kulakwitsa kwapakalipano kuli kochepa kwambiri, kauntala ya coulomb ipitilira kusonkhanitsa zolakwikazo, ndipo cholakwika chosonkhanitsidwa chimatha kuthetsedwa pokhapokha mutalipira kapena kutulutsa kwathunthu.

Dynamic voltage algorithm Meta yamagetsi imayerekeza momwe batire ilili potengera mphamvu yamagetsi;Chifukwa sichimaganiziridwa ndi chidziwitso chamakono cha batri, sichidzasonkhanitsa zolakwika.Kuti muwongolere kulondola kwazomwe zimayendera, mphamvu yamagetsi yamagetsi imayenera kugwiritsa ntchito chida chenichenicho kuti isinthe magawo a algorithm yokongoletsedwa molingana ndi mayendedwe enieni amagetsi a batri pansi pa chiwongolero chonse komanso kutulutsa kwathunthu.

Chithunzi 12. Magwiridwe a dynamic voltage algorithm magetsi mita ndikupeza kukhathamiritsa

Zotsatirazi ndikuchita kwa dynamic voltage algorithm pansi pamitundu yosiyanasiyana yotulutsa.Zitha kuwoneka kuchokera pachithunzicho kuti kulondola kwake kuli bwino.Mosasamala kanthu za kutulutsa kwa C/2, C/4, C/7 ndi C/10, cholakwika chonse cha SOC cha njirayi ndi chochepera 3%.

Chithunzi 13. State of charge of dynamic voltage algorithm pansi pamitengo yosiyana yotulutsa

Chithunzi chomwe chili pansipa chikuwonetsa momwe batire ilili panthawi yaifupi komanso kutulutsa kochepa.Kulakwitsa kwa boma kudakali kochepa kwambiri, ndipo cholakwika chachikulu ndi 3%.

Chithunzi 14. Kulipiritsa kwa dynamic voltage aligorivimu pakangotsala pang'ono kutulutsa batire

Poyerekeza ndi coulomb metering coulometer, yomwe nthawi zambiri imayambitsa vuto lolakwika chifukwa cha kulakwitsa kwamakono ndi kudzidzidzimutsa kwa batri, mphamvu yamagetsi yamagetsi sikudziunjikira zolakwika ndi nthawi ndi zamakono, zomwe ndi mwayi waukulu.Chifukwa palibe chidziwitso chaposachedwa / chotulutsa, mphamvu yamagetsi yamagetsi imakhala yosalondola kwakanthawi kochepa komanso nthawi yoyankha pang'onopang'ono.Kuphatikiza apo, sichingayerekeze kuchuluka kwa ndalama zonse.Komabe, imachita bwino pakulondola kwanthawi yayitali chifukwa mphamvu ya batire pamapeto pake imawonetsa momwe amalipira.
