Emyaka mwenda mu kugula ebidduka gyanjigiriza ekintu kimu ku bibuuzo ebikwata ku bulamu bwa bbaatule: eky’okuddamu ky’ofuna kisinziira ddala ku ani atunda.
Buuza omugabi wa lithium? "Emyaka kkumi ku abiri, gyangu." Buuza ggaayi akyusa lead-acid pack yo efudde oluvannyuma lw'okumala summer bbiri mu Phoenix? Ajja kumala kuseka.
Bino bye bigenda mu maaso ddala mu nnimiro, okuggyako kkopi y’okutunda.
Eky'okuddamu Ekimpi Tewali Ayagala Kuwulira
Omusulo-Asidi
Emyaka esatu ku etaano
Bwoba olina empisa ku nsonga z'okuddaabiriza. Ebimotoka ebisinga si bwe bityo. Nze nsika packs ku myezi 22 nga ziringa nga ziyise mu lutalo.
Lithium
Emyaka munaana ku kkumi n’ebiri
"Should" okukola ennyo okusitula ebizito mu sentensi eyo. Nze ndabye lithium packs zigwa ku myaka esatu kubanga waliwo eyaddukanya chargers ezitakwatagana okumala emyezi mukaaga nga tewali akitegedde.
Ekituli wakati w’ennamba za datasheet ne ky’ofuna mu butuufu ssente zonna we zigenda.
Lwaki Battery Zo Zifa Nga Tezinnaba Kufa
Sigenda kukutambuza mu kemiko wa bbaatule. Omanyi emisingi oba kino tewandisomye. Kye muyinza obutamanya lwaki cycle yo eyasembayo ey’okukyusaamu yajja nga bukyali emyaka ebiri.
Ebbugumu osanga likutta mu kiseera kino.
Nalina maintenance manager mu Scottsdale, guy ayitibwa Mike, mpita absolutely furious mu 2023. Eyamusooka yali aguze decent lead-acid setup, spec'd for five years. Afudde ku myezi kkumi na munaana. Bwe navuga ebweru eyo, ekisenge kya bbaatule kyali kikuba mid-fifties Celsius mu musana ogw’emisana. Ebigaali ebyo byatuulanga mu kifo ekitali kibikkiddwa wakati wa lawundi. Tewali yakirowoozaako mu kiseera ky’okugula ebintu. Tewali yakyogerako mu kiseera ky’okussaako. Omuntu yenna we yakebedde ebbugumu, okwonooneka kwali kuwedde.
Asidi w’omusulo-akendeeza ku kitundu ky’obulamu bwe ku buli diguli kkumi waggulu wa diguli 25 . Oyo si nnamba ntuufu, okusinga okufaanana etteeka erikakali lye ndabye nga likwata waggulu okubuna mpozzi embeera amakumi ana ez’enjawulo. Lithium akwata bulungi ebbugumu naye si nnyo bwetyo. EVE's data eraga ekintu nga 7,000 cycles ku room temp okukka mpozzi 2,500 ku 45℃. Tonjuliza ku miwendo emituufu, naye obulagirizi butegeerekeka bulungi.
Omutego gwa lithium ogwa 4x12V.
Bw’oba oddukanya paaka za lithium nnya eza 12-volt eziriko waya mu series ku 48V, ekizibu kino okimanyi dda. Oba ogenda okukikola.
Buli pack erina BMS yaayo. Teboogera bokka na bokka. Mu myezi mukaaga, mpozzi n’omwaka, ziwuguka okuva mu bbalansi. Pack esinga obunafu ekuba cutoff voltage yaayo ate endala zikyalina capacity ya 20% esigadde. Baddereeva bo batandika okwemulugunya ku range. Ba maintenance guys bo batandika okugoba emizimu.
Nalaba ekibinja ky'ebigaali 60-mu Georgia nga kimala emyezi munaana nga kigezaako okuzuula "okuggalawo okutali kwa bulijjo" nga tannamaliriza kupima vvulovumenti za pack ssekinnoomu. Ebigaali 23 byali bya pack imbalances ezisukka mu volt emu n’ekitundu. Okutereeza kwali kwa manual rebalancing buli luvannyuma lwa myezi mitono oba okukyusa buli kimu ne bassaamu unified 48V packs. Baagenze n’abakyusiddwa. Essomo ery’ebbeeyi.
Obutakwatagana bwa charger busaanyawo lithium mangu.
Ono akyannyiiza kuba aziyizibwa nnyo. Chaja za asidi eza lead-zikola loose voltage tolerances, oluusi 5% oba okusingawo. Lithium yeetaaga okufugibwa ennyo, wansi wa 1%. Ndabye ebivudde mu kukebera nga lead-acid charger ku lithium pack yaleeta 50% capacity loss mu charge cycles amakumi abiri. Enzirukanya amakumi abiri. Ekyo tekiwera mwezi gumu nga zikola ku bidduka ebisinga obungi.
Ekitundu ekisinga obubi? Oyo yenna eyakola switch osanga yalowooza nti bakekkereza ssente nga bakuuma chajingi enkadde.
Waranti By’ekola Mu butuufu (Ebiseera Ebiseera Ebitono Okusinga Bw’olowooza)
Nze nkoledde mpozzi warranty claims kkumi na ttaano mu career yange. Ebibiri byatambudde bulungi. Ebisigadde byali bizingiramu wiiki z'okudda-ne{3}}mu ku "embeera z'okukozesa" ne "ebiwandiiko by'okuddaabiriza" ne "engeri z'okulemererwa eziggyiddwamu."
Ebya Dakotaggaranti y'emyaka kkumi n'emu-erabika bulungi nnyo ku lupapula. Nze mpulidde okuva mu ba operators babiri abagezezzaako okugikozesa. Omu yalinze emyezi musanvu okugonjoolwa. Omulala yalekulira n’agula bbaatule empya.
Trojanerina ebikozesebwa ebirungi, naye ebisaanyizo byabwe eby’okubikka binywevu. Soma ebiwandiiko ebirungi ebikwata ku mitendera gy’okukuuma obusobozi.
RELiON'sbeen decent mu experience yange, naye sample size yange ntono. Ebigambibwa bisatu, byonna byagonjoddwa mu wiiki ezitakka wansi wa mukaaga.
Ensonga si nti brand yonna entongole mbi. Ensonga eri nti obuwanvu bwa warranty tebulina kye butegeeza nga totegedde nkola ya claims. Buuza supplier wo references okuva mu bakasitoma abamaze ddala okussaayo claims. Bwe baba tebasobola kuwaayo yonna, ekyo kibaako ky’akugamba.
The ROI Math Buli Omu Afuna Obukyamu
Okubala omuwendo gwonna ogw’obwannannyini kulabika bulungi nnyo mu biteeso. Nze mpandiise amakumi gazo. Era zisinga kuba fiction.
The standard pitch: lithium egula ssente nnyingi mu maaso naye akekkereza ssente mu myaka kkumi okuyita mu kukendeeza ku ndabirira, okukyusaamu okutono, n’okukendeeza ku ssente z’amasannyalaze. Okubala kutera okukola okutuuka ku kintu nga 30% ku 40% okutereka.
Laba bino spreadsheet by'etakwata.
"CFO wo tafaayo ku kutereka kwa myaka kkumi-. Afaayo ku mbalirira ya kwata eno. Nfiiriddwa okubala emirundi emeka gye nnayanjudde omusango gwa TCO ogutayingiramu masasi okuwulira nti 'tetulina capex mu kiseera kino, tusobola okugikola mu mutendera?'"
Okukyusa mu mitendera kuleeta ebizibu byabwe. Ebimotoka ebitabuddwa kitegeeza enkola z’okuddaabiriza ezitabuliddwa, ebika bya chajingi ebitabuddwa, ebyetaago by’okutendekebwa ebitabuddwa. Amagoba mu bulungibwansi ge wateebereza gakitwala nti cutover ennyonjo. Reality esingako okutabula.
Era ebyo ebikekkereza amaanyi? Ddala ddala naye era tezirabika. Tewali agenda kukuyozaayoza olw'okukendeeza ku ssente z'okusasula ebitundu 25% kubanga tewali alondoola ssente za kusasula mu ngeri entuufu bwetyo. Mu kiseera kino, ekiragiro ky’okugula ddoola 150,000 mu bbaatule za lithium kirabika nnyo.
Sigamba nti tokola kukyusa. Nze ngamba tegeera ky'otunda ddala munda era otegeke okusinziira ku ekyo.
Kye Nnandikoze Mubutuufu Ne Ssente Zo
Bwoba okola omulimu gwa high-volume mu mbeera y'obudde ensaamusaamu, lithium ekola amakulu. Si lwa kubala kwa myaka kkumi-. Olw’okuba ttiimu yo ey’okuddaabiriza ejja kulekera awo okukukubira essimu ku bbaatule ezifudde, ebigaali byo bijja kubaawo nga bakasitoma baagala, era tojja kuba na mboozi eyo ne GM buli luvannyuma lwa myezi kkumi na munaana ku nsonga lwaki okukyusa bbaatule kuddamu kusukka mbalirira.
Bw’oba oli mu bbugumu erisukkiridde, kola embalirira y’okuddukanya ebbugumu oba kkiriza okuwangaala okumpi. Tewali bbaatule ya magezi egonjoola embeera z'eddungu. Oba osiiga ekisiikirize mu kifo kyo eky’okuteeka siteegi, oyongerako ekinyogoza oba okikyusa emirundi mingi. Londako emu.
Singa CFO wo tajja kukkiriza kukyusa mu bujjuvu, teesa ku mugenyi. Kyuusa ebigaali kkumi, bidduke nnyo okumala omwaka mulamba, wandiika buli kimu. Data entuufu okuva mu nkola yo yennyini ya muwendo okusinga okunoonyereza kwonna okw’omutunzi.
Era ku ky’omuwendo, nkomye okuteesa ku budget lithium options yonna. Enjawulo mu bbeeyi wakati wa pack ya doola 1,500 ne pack ya doola 2,500 ebula mangu ng’okola ku nsonga z’omutindo gw’amasimu oba BMS okulemererwa oba abagaba ebintu abatakwata ssimu nga waliwo ekikyamu.
Ebintu Tewali Ateka Mu Nnyingo
Enkolagana yo eya sales rep nsonga okusinga brand selection yo.Nkimanyi nti ekyo kiwulikika nga kya kunyooma. Era kituufu. Ekintu bwe kiremera ku ssaawa 2 ez’oku makya ng’empaka tezinnabaawo, weetaaga omuntu akwata essimu. Ekyo si kya nkola ya bitongole. Kikwata ku oba rep wo akutwala nga priority.
Ebiragiro by’okusasula biteesebwako naddala ku nkomerero y’omwaka.Nze ndabye discounts 15% just for timing a purchase right.
"Fleet pricing" ekyukakyuka nnyo okusinziira ku ani abuuza.Funa quotes eziwera. Buli supplier mutegeeze nti ofuna quotes eziwera. Ennamba esooka si nnamba ntuufu.
Omutindo gw’okukwatagana kw’obutoffaali y’enjawulo wakati wa paaka ezisigala nga zikwatagana ne paaka eziwuguka.Saba data y’obuziyiza obw’omunda ku batch yo. Abagaba ebintu abamanyiddwa bagezesa n’okukwataganya obutoffaali. Abalala tebakikola, era bajja kukyusa ensonga ng’ogireese.
Ttiimu yaffe ekola okwekenneenya ebidduka n’okuteekateeka okukyusa. Bw’oba oyagala okwogera ng’oyita mu mbeera yo entongole, tuukirira. Tewali kusasula ku mboozi esooka.
