baytariga lithiumayaa la sheegay in aan dhib lahayn, Dhab ahaantii, ma aha mid aad u adag, ayaa sheegay in fudud, dhab ahaantii, ma fududa.Haddii aad ku hawlan tahay warshadahan, markaa waa lagama maarmaan in la barto qaar ka mid ah ereyada caadiga ah ee loo isticmaalo warshadaha baytariga lithium, markaa, waa maxay ereyada caadiga ah ee loo isticmaalo warshadaha baytariga lithium?
Erayada caadiga ah ee lagu isticmaalo warshadaha baytariyada lithium
1.Qiimaha-Qiimaha/Heerka-Dhijinta
Waxay muujinaysaa inta hadda ah ee lagu dallaci karo iyo soo saarista, guud ahaan loo xisaabiyo sida tiro badan oo ka mid ah awoodda magaca ah ee batteriga, guud ahaan loo tixraacayo dhowr C. Sida batteriga awoodda 1500mAh, waxaa lagu qeexay in 1C = 1500mAh, haddii lagu sii daayo 2C sidoo kale waxaa lagu sii daayay 3000mA hadda, 0.1C lacag ah iyo sii deynta ayaa lagu dalacay waxaana lagu sii daayay 150mA.
2.OCV: Korantada wareegga furan
Korontada baytarigu guud ahaan waxa ay tilmaamaysaa danabka magacaaban (sidoo kale loo yaqaan danabka la qiimeeyay) ee baytariga lithium.Korontada magaceed ee baytariyada lithium-ka caadiga ah guud ahaan waa 3.7V, sidoo kale waxaan ugu yeernaa madal danabkeeda 3.7V.Danab ahaan waxaan guud ahaan tixraacnaa danabka wareegga furan ee batteriga.
Marka batteriga uu yahay 20 ~ 80% awoodda, korantadu waxay ku urursan tahay agagaarka 3.7V (qiyaastii 3.6 ~ 3.9V), aad u sarreeya ama aad u hooseeya, korantadu si ballaaran ayey u kala duwan tahay.
3.Tamarta/Awoodda
Tamarta (E) uu batarigu dami karo marka lagu sii daayo heer cayiman, Wh (watt hours) ama KWh (saacadaha kilowatt), marka lagu daro 1 KWh = 1 kWh oo koronto ah.
Fikradda aasaasiga ah waxaa laga helaa buugaagta fiisigiska, E=U * I*t, kaas oo sidoo kale la mid ah danab batari oo lagu dhufto awoodda batteriga.
Qaacidada awoodduna waa, P=U*I=E/t, taasoo tilmaamaysa xadiga tamarta ee la sii dayn karo halbeegkiiba.Cutubku waa W (watt) ama KW (kilowatt).
Batari awoodiisu tahay 1500 mAh, tusaale ahaan, waxa uu leeyahay danab magaciisu yahay 3.7V, markaa tamarta u dhiganta waa 5.55Wh.
4. iska caabin
Maaddaama dallacaadda iyo ka-saarista aan lala simi karin koronto ku habboon, waxaa jira iska caabin gudaha ah oo gaar ah.Iska caabbinta gudeedku waxay isticmaashaa tamar, dabcan, iska caabbinta gudaha ee yar ayaa ka sii fiican.
Iska caabinta gudaha batteriga waxaa lagu cabbiraa milliohms (mΩ).
Iska caabbinta gudaha ee baytariga guud wuxuu ka kooban yahay iska caabin gudaha ohmic iyo caabbinta gudaha.Cabbirka caabbinta gudaha waxaa saameeya walxaha batteriga, habka wax soo saarka, iyo sidoo kale qaabka batteriga.
5.Cycle Life
Dallacaadda batteriga iyo daynta hal mar waxa loo yaqaan wareeg, nolosha meertada waa tilmaan muhiim ah oo muujinaysa waxqabadka nolosha batteriga.Halbeegga IEC waxa uu dhigayaa in batariyada lithium talefanka gacanta, 0.2C ka bixista 3.0V iyo 1C dallaca ilaa 4.2 V. Kadib 500 wareeg oo soo noqnoqda, awoodda baytarigu waa in ay ahaataa in ka badan 60% awoodda bilowga ah.Si kale haddii loo dhigo, nolosha meertada ee baytariga lithium waa 500 jeer.
Heerarka qaranku waxa uu dhigayaa in 300 wareeg ka dib, awooddu ay ku sii jirto 70% awoodda bilowga ah.Baytariyada ka hooseeya 60% ee awoodda bilowga ah waa in guud ahaan loo tixgeliyo qashinka qashinka.
6.DOD: Qoto dheer ee Soosaarida
Lagu qeexay sida boqolkiiba awoodda laga soo saaray batteriga sida boqolkiiba awoodda la qiimeeyay.Markasta oo qoto dheer sii daynta batteriga lithium guud ahaan, cimriga batteriga ayaa sii yaraanaya.
7.Cut-Off Voltage
Danab-ka-joojintu waxay u qaybsan tahay dallacaadda joojinta danabaynta iyo tamarta joojinta, taasoo macnaheedu yahay danabka aan batteriga lagu dallaci karin ama lagu sii dayn karin.Korantada joojinta tamarta ee baytariga lithium guud ahaan waa 4.2V iyo danab joojinta dallacadu waa 3.0V.Ku dallacaadda qoto dheer ama ku shubista baytariga lithium ee ka baxsan tamarta joojinta waa mamnuuc.
8.Iska-baxa
Waxa loola jeedaa heerka hoos u dhaca awoodda batteriga inta lagu jiro kaydinta, oo lagu muujiyay hoos u dhac boqolkiiba ah ee nuxurka halbeeggii wakhtiga.Heerka is-soo daynta ee baytariga caadiga ah ee lithium waa 2% ilaa 9%/bishii.
9.SOC(State of Charge)
Waxa ay tilmaamaysaa boqolleyda dallaca ka hadhsan batteriga ilaa wadarta kharashka la dayn karo, 0 ilaa 100%.Waxay ka tarjumaysaa kharashka hadhay ee batteriga.
10.Awoodda
Waxa loola jeedaa cadadka awoodda laga heli karo lithium baytariga marka la eego xaaladaha sii daynta qaarkood.
Qaaciddada korontadu waa Q=I*t oo ku jirta coulombs iyo unugga awoodda batteriga waxaa lagu qeexaa sida Ah (ampere hours) ama mAh (saacadaha milliampere).Waxay ka dhigan tahay in batari 1AH ah la sii dayn karo 1 saac oo leh hadda 1A marka si buuxda loo dallaco.
