Enkyukakyuka okuva ku lead-asidi okudda mu lithium-enkola za bbaatule mu nkola za fooro ez’amasannyalaze ekiikirira ekimu ku bisinga obukulu mu kukyusa tekinologiya mu byuma ebikwata ebintu mu myaka kkumi egiyise.Lithium ekyuma phosphate (LifePO4) .Chemistry evuddeyo nga eky’okugonjoola ekikulu eky’okukozesa amaanyi g’amakolero, nga kiwa densite z’amasoboza wakati wa 120-180wh/kg bw’ogeraageranya ne 30-50Wh/kg emanyiddwa ennyo mu nsengeka z’omusulo-asidi ez’ennono. Enkizo eno ey’amasannyalaze evvuunula butereevu mu magoba amalungi ag’emirimu abaddukanya sitoowa n’abaddukanya eby’okutambuza ebintu bye batasobola kubuusa maaso.
Lwaki buli omu afaayo mu bwangu ku nsonga eno .
Here's the thing about forklifts abantu abasinga ebweru w'omulimu guno tebamanyi: ebyuma bino bitambula buli kiseera. Tuli mu kwogera 16, oluusi essaawa 20 buli lunaku mu bifo ebinene eby’okugabira abantu ebintu. Engeri enkadde ey’okukolamu ebintu-okuwuubaala omusulo omuzito-acid batteries, okukuuma ebisenge bya bbaatule ebiweereddwayo nga birimu asidi-okuziyiza wansi n’enkola z’okuyingiza empewo, okubeera n’abakugu bakebera emitendera gy’amazzi buli wiiki-nti ebizimbe byonna bifuuka bifuuse ne tekinologiya wa lithium.
Nze ndabye ebifo nga bisaasaanya ddoola ezisukka mu 50,000 ku kuzimba ekisenge kya bbaatule zokka. Omukka gwa asidi, okuziyiza okuyiwa, siteegi z’okunaaba amaaso, setup yonna. Lithium packs tezifaayo ku kintu kyonna ku ebyo. Osobola okuzisasuza mu nsonda ya sitoowa yo. Tekyetaagisa kisenge kya njawulo.
Ekibuuzo kya Chemistry .
Battery za lithium zonna tezitondebwa kwenkana, era kino kikulu okusinga abaguzi abasinga bwe bakitegeera.
LFP (Ekyuma kya Lithium phosphate) .Afuga akatale ka Forklift olw’ensonga entuufu. The thermal runaway threshold etudde ku 270℃, bw’ogeraageranya ne roughly 150℃ku NCM chemistries. Bw’oba okola ebyuma ebizito mu mbeera nga ebikosa bibaawo-Kubanga ka tubeere beesimbu, abaddukanya forklift bakuba ebintu-nti obukuumi bw’obukuumi bufuuka non-okuteesa. Obulamu bw’enzirukanya mu bujjuvu buva ku cycle 2,500 okutuuka ku 4,000 ku 80% mu buziba bw’okufulumya.
Battery za NCM ne NCA ziraga oluusi n’oluusi, okusinga mu nkola ez’enjawulo ez’okutereka eby’ennyogovu nga mu ngeri ey’enjawulo ey’okubunyisa akabi, engeri zazo ez’okubunyisaamu ez’ebbugumu ziraga ebyetaago ebirala eby’okuddukanya akabi. Naye be ba exception.
LTO (lithium titanate) esaana okwogerwako kubanga abamu ku bakola ebintu bagisika nnyo olw’ensonga z’okucaajinga ez’amaanyi (ultra-Fast charging scenarios. Tekinologiya akola-osobola okusasuza mu butuufu packs zino mu 15-eddakiika 20-naye ekibonerezo ky'obungi bw'amasoboza kibeera kya maanyi. Otunuulira nga 70wh/kg. Ku mirimu egisinga obungi, okubala tekukola.
kiki ddala ekibaawo munda mu pack .
Enkola y’okuddukanya bbaatule eyinza okuba ekitundu ekisinga obutasiimibwa mu kibiina kyonna. BMS ennungi ekola ekisinga okuziyiza omuliro.
Okugerageranya obutoffaali kwokka kuyinza okugaziya obulamu bwa pack ne 20-30%. Obutoffaali obw’omuntu ku bubwe munda mu modulo tekyewalika bujja kukaddiwa ku miwendo egy’enjawulo katono olw’enjawulo mu kukola n’okukyukakyuka kw’ebbugumu mu kiseera ky’okukola. Awatali kukola bbalansi, akatoffaali ko akasinga obunafu kafuuka ensonga ekoma ku pack yonna. Enkola mu bukulu efuuka olujegere-yokka-nga -enywevu-nga -Embeera yaayo-enafu esinga obunafu.
State of charge okubalirira mu lithium chemistries kuleeta okusoomoozebwa okwa nnamaddala okw’ekikugu. Voltage curve ya LFP cells ebeera flat mu ngeri eyeewuunyisa okuyita mu makkati 60% of the discharge cycle. Tosobola kumala kupima voltage n'ofuna SOC mu ngeri gy'osobola n'omusulo-acid. Enkola ez’omulembe zikozesa Coulomb okubala nga zigatta wamu ne Kalman filtering ne periodic relibration okusinziira ku bifo ebimanyiddwa eby’okujuliza (full charge voltage, discharge endpoints).
Okulondoola ebbugumu kubaawo ku bifo ebingi-ebiseera ebisinga buli 8-12 obutoffaali-nga shutdown protocols triggering singa sensa yonna esukka threshold values. Empuliziganya ya CAN Bus eriisa data eno ku forklift’s main controller obutasalako.
Emboozi ya ssente .
Wano ebintu we bifunira okusanyusa, era we ndabye ttiimu z’okugula ebintu nga zikola ensobi ez’ebbeeyi.
Omuwendo gw’okugula okusooka ku lithium pack gutambula emirundi nga 2.5 ku 3 ku muwendo gw’omusulo ogwenkanankana-battery ya asidi. Omuwendo ogwo gutiisa abantu. Tekirina, naye kikola.
Lowooza ku nkola eya bulijjo eya 80V/500AH ekola enkyukakyuka bbiri:
Lead-Acid scenario yeetaaga battery pack bbiri (emu charging ate emu ekola), charger, ebyuma ebikwata bbaatule, n'ebintu bya bbaatule ebyogeddwako waggulu. Era okyusa bbaatule ezo buli myaka 4-5. Ebisale by’abakozi mu kuwanyisiganya bbaatule buli lunaku bigatta ku up-figure eddakiika 15-20 buli swap, emirundi ebiri buli lunaku, ku kyonna ekigitisse omuwendo gw’abakozi.
Lithium pack emala emyaka 8-10 ng’eddukanya bulungi. Tewali kukyusakyusa. Tewali kisenge kya bbaatule. Okusasula omukisa mu biseera by’okuwummulamu kikuuma nga kidduka ekiseera ekitali kigere.
Dduka okubala kwa TCO ku 10-Year horizon ne lithium mu ngeri entuufu biwangula 25-40%, okusinziira ennyo ku miwendo gy’amasannyalaze egy’omu kitundu n’ebisale by’abakozi. Emirimu gya shift esatu laba Payback mu myezi 18-24. Single-shift applications ziyinza obutatuuka ku payback, y’ensonga lwaki bulijjo mbuuza ku nkola z’okukozesa nga sinnasemba kintu kyonna.
Okutereka mu ngeri ennyogovu: Ensolo ey’enjawulo .
Okusaba kwa firiiza wansi wa -20℃kuleeta okusoomoozebwa okw’enjawulo okusaana okukubaganya ebirowoozo okwawukana.
Standard lithium packs zifuna okukendeeza ku busobozi obw’amaanyi ku bbugumu eri wansi-oluusi okufiirwa 30-40% ku -25℃. Obutambuzi bwa ayoni bwa electrolyte bukendeera nnyo. Obuziyiza obw’omunda bweyongera. Okugezaako okusaajaza pack ennyogovu ennyo kiteeka lithium plating ku anode, ekyonoona obutoffaali enkalakkalira n’okuleeta obulabe ku bukuumi.
Ekigendererwa-Battery ezimbiddwa mu kutereka ennyogovu ziyingizaamu enkola z’ebbugumu ezikola nga tezinnaba kutandika. Dizayini ezimu zikozesa ebintu ebibuguma ebiziyiza; Abalala batambula n’amazzi agabuguma agabuguma. Pack tegenda kukkiriza charge okutuusa nga ebbugumu ly’obutoffaali lisusse omusingi omutono, mu bujjuvu nga 0℃.
Kino kyongera obuzibu, omuwendo, n’ebifo ebiyinza okulemererwa. Naye eky’okuddako-okuleeta bbaatule okufuluma okutuuka ku bbugumu eribeera mu kifo nga tonnaba kusasula-esobya ku birungi by’emirimu ebyawa obujulizi ku nsimbi za lithium mu kifo ekisooka.
Okuteeka ebintu ebituufu .
Pulagi-era-okuzannya okutunda tekuyogera ku mboozi yonna.
Engabanya y’obuzito nsonga nnyo mu counterbalanced forklifts. lead-batteries za asidi zikola nga essential ballast; Loole eno ekoleddwa ddala okwetoloola Mmisa eyo. Lithium packs zizitowa ebitundu 50-70% wansi. Abasinga abakola ebintu bino bongerako obupande obuyitibwa steel ballast plates, naye kino kyetaaga yinginiya omutuufu. Nze ndabye okukyusa obubi nga loole zifuuka unstable under load.
Okukwatagana kwa charger nakwo tekukakasiddwa. lead-acid chargers zikozesa fundamentally different charging profiles-bulk, okunyiga, emitendera gy'okwenkanankana-ejja okwonoona obutoffaali bwa lithium. Okwetaaga Lithium-Ebyuma ebitongole ebicaajinga nga biriko CC entuufu-CV curves ne BMS Communication Capability.
Ebipimo ebiteekebwako oluusi bikola, oluusi tebikola. Enkyukakyuka mu kifo kya bbaatule si za bulijjo.
Okukakasa ssupu wa alfabeti .
Ku muntu yenna agula bbaatule, embeera y’okulungamya mulimu:

Okuteeka obubonero ku CE okusindikibwa mu Bulaaya .
Tokkiriza bbaatule nga tolina biwandiiko bituufu. Kino si bukuumi bwa buvunaanyizibwa bwokka-Kya musingi nti omuntu ddala yagezesa ekintu nga tannakitunda.
Okuddaabiriza (oba obutabaako) .
Ekimu ku birungi ebituufu: Lithium packs zeetaaga kumpi tewali kuddaabiriza kwa bulijjo.
Tewali kufukirira. Tewali kusasula ssente za kwenkanankana. Tewali kusengejja kwa asidi. Tewali terminal corrosion okuyonja. BMS ekwata balancing automatically.
By’osaanidde okukola: Okukebera okulaba buli luvannyuma lwa kiseera olw’okwonooneka kw’omubiri, okukebera embeera y’ekiyungo, n’okuddamu okwetegereza amawulire okuva mu nkola y’okulondoola. Sofutiweya w’okuddukanya ebidduka ebisinga asobola okussaako akabonero ku butoffaali obulaga enneeyisa etali ya bulijjo nga tebinnaba kufuuka bizibu.
Ekitundu ky’okulondoola kikulu nnyo okusinga abantu bwe bakitegeera. Enkola zino zikola data ennene ey’okuzuula obulwadde. Okugikozesa proactively kigaziya obulamu bwa pack; Okubuusa amaaso kitegeeza okukyusa bbaatule nga bukyali okusinga bwe kyetaagisa.
Enkyukakyuka y'obufirosoofo bw'okusasuza .
Okusasula emikisa mu musingi kukyusa engeri emirimu gye girowooza ku nzirukanya y’ebyuma.
lead-battery za asidi zisinga kwagala kufulumya mu bujjuvu-enzitoya z'ekisannyalazo. Okucaajinga ekitundu kuleeta ebikolwa eby’okujjukira n’ensonga z’okusengeka (stratification). Mu bukulu olina okuteekateeka enkozesa ya bbaatule yo.
Obutoffaali bwa lithium businga kwagala enzirukanya y’ekitundu. Okucaajinga okuva ku bitundu 40% okutuuka ku 80% mu kiseera ky’okuwummulamu ekyemisana kirungi-okuyamba, mu butuufu. Okukuuma embeera y’okusasula wakati wa 20% ne 80% kiyamba obulamu bwa cycle. Olekera awo okulowooza ku nzirukanya ya bbaatule ng’omulimu ogw’okukola ogw’enjawulo n’otandika okugutwala ng’omulimu ogw’emabega ogugenda mu maaso.
Kino kisobozesa enkola entuufu eya multi-nga tewali nkyukakyuka ya bbaatule. Pack emu, loole emu, 24-okubikka essaawa. Ebikosa ebivaamu mu mbeera eziyita mu bitundu ebingi biba bingi.
ebintu gye bitambula obubi .
Emitendera egya bulijjo egy’okulemererwa egisaanye okutegeera:
- BMS Okulemererwa .account for ekitundu ekyewuunyisa eky’okusaba kwa warranty. Ebyuma ebikozesebwa mu byuma bibeera mu mbeera enkambwe-okukankana, okuwuubaala kw’ebbugumu, amaloboozi g’amasannyalaze okuva mu bifuga mmotoka. Omutindo gwawukana nnyo wakati w’abakola ebintu.
- Contactor Okuweta .kibaawo nga main power contactors zifuka nga ziggaddwa, ebiseera ebisinga kiva ku inrush current events. Enkola ezikoleddwa obulungi mulimu pre-okusannyalala okuziyiza kino. Dizayini za layisi oluusi tezikola.
- Ensobi mu mpuliziganya .Wakati wa BMS ne forklift controller kiyinza okuleka loole nga zisibye ne bwe kiba nti bbaatule yennyini ekola bulungi. Asobola Okussa mu nkola ensonga z'omutindo gw'okussa mu nkola.
Okulemererwa kw’obutoffaali kubaawo naye nga tekutera kubaawo n’abakola ebintu eby’ettutumu. Bwe zibaawo, dizayini za modular pack zikkiriza okukyusa modulo ezikoseddwa okusinga bbaatule yonna.
Nga tutunuulira mu maaso .
Solid-State batteries zisigala nga buli kiseera "emyaka etaano" for automotive applications, naye technology timeline for industrial motive power likely stopre long. Enkola z’amasannyalaze ez’amazzi eziriwo kati zikola bulungi ekimala nti puleesa y’okukyusa ekoma.
Ekisinga okunyumira okumpi-Enkulaakulana za term mulimu silicon-obutoffaali bwa anode obuyinza okusika amaanyi g’amaanyi agasukka 200wh/kg, n’okugenda mu maaso n’okukendeeza ku nsaasaanya ng’ekipimo ky’okukola kyeyongera. Battery-as -a-Empeereza z'obuweereza zifuna okusika, naddala ku mirimu emitono egitasobola kunyiga nsaasaanya ya kapito nnene.
Enkola eno etegeerekeka bulungi. Okutunda kwa forklift okupya kweyongera okusookerwako ku nsengeka za lithium. Lead-Acid tebula ekiro-Waliwo omusingi omunene oguteekeddwawo era tekinologiya asigala nga alina amakulu mu by'enfuna ku nkola entono-okukozesa-naye enkyukakyuka eyise mu kifo kyayo eky'okuyita.
Oba tekinologiya ono akola amakulu ku nkola eyenjawulo kisinziira ddala ku bikwata ku nsonga: essaawa z’okukozesa, engeri y’okukyusaamu, embeera y’obutonde, kapito okubeerawo, n’ebintu ebikulu ebikulembeza mu nkola. Tewali kuddamu kwa bonna. Naye okutegeera engeri enkola zino gye zikolamu mu butuufu-okusukka ebikozesebwa mu kutunda-eddaala erisooka eryetaagisa okutuuka ku kusalawo okutegeerekeka.
