Kutheni ibalulekile nje? Kweli nqaku, siza kuhlolisisa intsingiselo yebhetri Ah kunye nendlela ebalwa ngayo, ngelixa sichaza izinto eziphambili ezichaphazela ukuthembeka kwezi zibalo. Ukongeza, siya kuphonononga indlela yokuthelekisa iintlobo ezahlukeneyo zeebhetri ezisekelwe kwi-Ah kwaye sinikeze abafundi ngesiphelo esibanzi ukubanceda baqonde ngcono kwaye bakhethe iibhetri ezihambelana neemfuno zabo.
Uthetha ukuthini uAh kwibhetri
12V 100Ah LiFePO4 Ibhetri Pack
I-Ampere-yure (Ah) yiyunithi yomthamo webhetri esetyenziselwa ukulinganisa ukukwazi kwebhetri ukubonelela ngoku kwithuba elithile lexesha. Isixelela ukuba ingakanani ibhetri ekhoyo ngoku enokuhanjiswa ngexesha elinikiweyo.
Masizekelise ngemeko ecacileyo: khawufane ucinge ukuba uhamba intaba kwaye ufuna ibhanki yamandla ephathwayo ukugcina ifowuni yakho ihlawulwe. Apha, kuya kufuneka uqwalasele umthamo webhanki yamandla. Ukuba ibhanki yakho yamandla inomthamo we-10Ah, ithetha ukuba inokubonelela ngoku i-10 amperes ngeyure enye. Ukuba ibhetri yefowuni yakho inomthamo oyi-3000 milliampere-iiyure (mAh), ngoko ke ibhanki yakho yamandla inokutshaja ifowuni yakho malunga neeyure ezingama-300 zemiliampere (mAh) kuba i-1000 milliampere-iiyure (mAh) ilingana neyure enye yeampere (Ah).
Omnye umzekelo yibhetri yemoto. Masithi ibhetri yemoto yakho inomthamo we-50Ah. Oku kuthetha ukuba inokubonelela ngoku ye-50 amperes ngeyure enye. Ukuqala kwemoto eqhelekileyo, kunokufuna malunga ne-1 ukuya kwi-2 amperes yangoku. Ke ngoko, ibhetri ye50Ah yemoto yanele ukuqalisa imoto amatyeli amaninzi ngaphandle kokunciphisa ugcino lwamandla ebhetri.
Kwiinkqubo ze-UPS zendlu (Uninterruptible Power Supply), i-Ampere-yure nayo isalathiso esibalulekileyo. Ukuba unenkqubo ye-UPS enomthamo we-1500VA (Watts) kunye nombane webhetri yi-12V, ngoko amandla ayo ebhetri yi-1500VA ÷ 12V = 125Ah. Oku kuthetha ukuba inkqubo ye-UPS ngokwethiyori inokubonelela ngomsinga wee-amperes ezili-125, ibonelela ngamandla okuxhasa izixhobo zendlu malunga neeyure ezi-2 ukuya kwezi-3.
Xa uthenga iibhetri, ukuqonda i-Ampere-hour kubalulekile. Inokukunceda ukuba ubone ukuba ibhetri ingasebenza ixesha elingakanani na izixhobo zakho, ngaloo ndlela ihlangabezana neemfuno zakho. Ngoko ke, xa uthenga iibhetri, hlawula ingqalelo ekhethekileyo kwiparamitha yeyure ye-Ampere ukuqinisekisa ukuba ibhetri ekhethiweyo inokuhlangabezana neemfuno zakho zokusetyenziswa.

Imiba ephambili echaphazela ukuthembeka kweBattery Ah Ukubala
Kufuneka uqaphele ukuba ukubalwa kwe "Ah" kwiibhetri akusoloko kuchanekile kwaye kunokwethenjelwa. Kukho ezinye izinto ezichaphazela amandla okwenene kunye nokusebenza kweebhetri.
Ziliqela izinto eziphambili ezichaphazela ukuchaneka kwezibalo ze-Ampere-yure (Ah), nazi ezimbalwa zazo, kunye neminye imizekelo yokubala:
- Ubushushu: Ubushushu buchaphazela kakhulu umthamo webhetri. Ngokuqhelekileyo, njengoko ubushushu bukhula, amandla ebhetri ayanda, kwaye njengoko ubushushu buyancipha, umthamo uyancipha. Umzekelo, ibhetri ye-lead-asidi enomthamo we-100Ah kwi-25 degrees Celsius inokuba nomthamo wokwenyani ongaphezulu kancinane.
ngaphezu kwe-100Ah; nangona kunjalo, ukuba iqondo lobushushu liyehla ukuya kwi-0 degrees Celsius, amandla okwenene anokuncipha ukuya kwi-90Ah.
- Intlawulo kunye nesantya sokukhupha: Intlawulo kunye nesantya sokukhupha ibhetri nayo ichaphazela amandla ayo okwenene. Ngokubanzi, iibhetri ezitshajiweyo okanye ezikhutshwe ngamaxabiso aphezulu ziya kuba namandla asezantsi. Ngokomzekelo, ibhetri ye-lithium ene-nominal umthamo we-50Ah ekhutshwe kwi-1C (umthamo wegama eliphindaphindwe ngomlinganiselo) unokuba nomthamo wangempela we-90% kuphela yomthamo wegama; kodwa ukuba ihlawuliswe okanye ikhutshwe kwizinga le-0.5C, amandla okwenene angasondela kumthamo oqhelekileyo.
- Impilo yebhetri: Njengoko iibhetri zikhula, amandla azo anokwehla ngokuthe ngcembe. Ngokomzekelo, ibhetri entsha ye-lithium inokugcina ngaphezu kwe-90% yomthamo wayo wokuqala emva kokuhlawuliswa kunye nemijikelezo yokukhupha, kodwa ngokuhamba kwexesha kunye nokunyuka kwemijikelezo yentlawulo kunye nokukhupha, umthamo wayo unokuncipha ukuya kwi-80% okanye nangaphantsi.
- Ukuhla kwe-voltage kunye nokuchasana kwangaphakathi: Ukuhla kwe-voltage kunye nokuchasana kwangaphakathi kuchaphazela amandla ebhetri. Ukonyuka kokunganyangeki kwangaphakathi okanye ukuhla kwamandla ombane kakhulu kunokunciphisa umthamo webhetri. Umzekelo, ibhetri ye-lead-asidi enomthamo we-200Ah inokuba nomthamo wokwenene we-80% yomthamo wegama ukuba ukuchasana kwangaphakathi kuyenyuka okanye ukuhla kwamandla ombane kugqithise.
Masithi kukho ibhetri ye-lead-acid ene-mominal umthamo we-100Ah, iqondo lokushisa eliphakathi kwama-25 degrees Celsius, intlawulo kunye nesantya sokukhupha i-0.5C, kunye nokuchasana kwangaphakathi kwe-0.1 ohm.
- Ukuqwalasela umphumo weqondo lokushisa: Kwiqondo lobushushu le-ambient ye-25 degrees Celsius, umthamo wangempela unokuba phezulu kancinci kunomthamo wegama, masicinge i-105Ah.
- Ukuqwalasela intlawulo kunye nesiphumo sezinga lokukhutshwa: Ukutshaja okanye ukukhupha kwizinga le-0.5C kunokubangela ukuba umthamo wangempela usondele kumthamo we-nominal, masicinge i-100Ah.
- Ukuqwalasela umphumo wempilo yebhetri: Masithi emva kwexesha elithile lokusetyenziswa, umthamo webhetri uyancipha ukuya kwi-90Ah.
- Ukuqwalasela ukuhla kwamandla ombane kunye nefuthe lokumelana kwangaphakathi: Ukuba ukuchasana kwangaphakathi kwanda ukuya kwi-0.2 ohms, umthamo wangempela unokuncipha ukuya kwi-80Ah.
Olu balo lunokubonakaliswa ngale fomyula ilandelayo:Ah = Wh / V
Apho,
- Hayi yiyure yeAmpere (Ah)
- Wh yiWatt-yure (Wh), emele amandla ebhetri
- V yiVoltage (V), emele amandla ombane ebhetri
Ngokusekelwe kwidatha enikiweyo, sinokusebenzisa le fomula ukubala esona sikhundla:
- Ngempembelelo yeqondo lokushisa, kufuneka sithathele ingqalelo kuphela ukuba umthamo wangempela unokuba phezulu kancinci kunomthamo we-25 degrees Celsius, kodwa ngaphandle kwedatha ethile, asikwazi ukwenza izibalo ezichanekileyo.
- Ngentlawulo kunye nesiphumo sezinga lokukhutshwa, ukuba umthamo wesigxina yi-100Ah kunye neyure ye-watt yi-100Wh, ngoko: Ah = 100Wh / 100V = 1Ah
- Kwisiphumo sempilo yebhetri, ukuba umthamo wegama ngu-100Ah kunye neyure ye-watt yi-90Wh, ngoko: Ah = 90 Wh / 100 V = 0.9 Ah
- Ukuhla kwamandla ombane kunye nefuthe lokumelana kwangaphakathi, ukuba umthamo we-100Ah kunye neyure ye-watt yi-80Wh, ngoko: Ah = 80 Wh / 100 V = 0.8 Ah
Isishwankathelo, le mizekelo yokubala isinceda ukuba siqonde ukubala kweyure ye-Ampere kunye nefuthe lezinto ezahlukeneyo kumthamo webhetri.
Ke ngoko, xa ubala "Ah" yebhetri, kufuneka uqwalasele ezi zinto kwaye uzisebenzise njengoqikelelo kunexabiso elichanekileyo.
