Iningi labaphathi bokuthengwa kwempahla bayaqhathanisaamanani ebhethri ye-forkliftngokubheka isitikha-$3,000 se-asidi yomthofu-, $15,000 ye-lithium. Isibalo sibonakala siqondile uze ucabangele lokho okufihlwe ngaphansi kwendawo. Ibhethri ye-forklift eyodwa idinga cishe imizuzu engama-20 yokunakekelwa kokunisela ngeviki. Kuwo wonke amayunithi{12}}emikhumbi engu-20 phakathi neminyaka emihlanu, lokho kuhlanganisa amashumi ezinkulungwane zamadola emsebenzini angakaze avele kunoma yiliphi i-oda lokuthenga. I-BMS{13}}isistimu yokuphatha ibhethri-yiyo enquma ukuthi utshalomali lwakho lwe-lithium luyaletha kulokho kulondoloza noma kuba ikhanda elibizayo elihlezi endaweni yokushaja.
I-CAN Protocol Matching: Inkinga Yobunjiniyela Besistimu
Ukufaniswa kwephrothokholi yebhasi OKUNGENZEKA kube yinkinga yobunjiniyela besistimu lapho nje umkhumbi wakho uhlanganisa ngaphezu kohlobo olulodwa lwe-forklift. AForklift lithium ibhethri BMSishidi elicacisiwe libala izinqubo zokuxhumana-ngokuvamile i-CAN 2.0B, J1939, noma i-RS485-kodwa lezo zifinyezo azisho lutho uze uqinisekise ukuhambisana kokuxhawulana nesilawuli sakho esithile. I-Curtis, i-Zapi, ne-Toyota izinhlelo ngayinye ilindele ukulandelana okuhlukile. Faka ibhethri elinezakhiwo ze-CAN ezingafani, futhi i-forklift iphonsa amakhodi ephutha noma isebenze ngaphandle kwedatha enembile{7}yokukhokhiswa kwedatha ephakela ubuchopho bemoto.
Yilapho izinkampani{0}}ezixubile ezithola khona ubunkimbinkimbi: i-warehouse esebenza kokubiliAmayunithi we-Linde ne-Yaleayikwazi ukucabanga ukuthi umphakeli webhethri oyedwa ukumboza kokubili, ngaphandle uma lowo mphakeli eqinisekisa ngokucacile ukusekelwa kwe-J1939 yochungechunge lwe-VX ye-Yale kanye nezivumelwano ze-Linde zobunikazi. Sibone amaqembu okuthenga exoxisana ngezephulelo ngobuningi kuphela ukuze athole uhhafu wamabhethri adinga ama-adaptha e-CAN avala iwaranti engasebenzi{2}}umphumela osula inzuzo yentengo ngokuphelele.
Yini Evikela I-Voltage Monitoring Empeleni
Yonke imininingwane ye-BMS yebhethri ye-forklift ibala ukunemba kokuqapha amandla kagesi, ngokuvamile azungeze u-±0.5% ngokulungiswa okungu-1mV. Inombolo izwakala inembe ngokwanele, kodwa inani layo elingokoqobo lincike ekutheni i-BMS ikuphatha kanjani ukungalingani kweseli phezu kwezinkulungwane zemijikelezo yokushaja.
Amaseli e-LiFePO4sebenza efasiteleni lamandla kagesi elincane-2.5V phansi ukuya kusilingi ongu-3.65V. I-BMS ekhukhuleka ngisho no-2% ekufundweni kwamandla kagesi izobangela ukunqanyulwa ngaphambi kwesikhathi noma, okuyingozi nakakhulu, ivumele izimo zokukhokhiswa ngokweqile kumaseli ngamanye kuyilapho ukufunda kwephekhi{9}}kuvela evamile. Yingakho iziqinisekiso ze-SOH (isimo sezempilo) ziye zaba umehluko wangempela phakathi kwabahlinzeki. Bheka iziqinisekiso ezicacisa u-75% SOH ezinyangeni ezingu-60{10}}isimiso esibamba kuphela uma i-BMS igcina ukuqapha okunembile kweseli ngalinye.
Uma sicaphuna-amaphrojekthi we-shift arehouse, isinqumo esisebenzayo uma siqhathaniswa ne-passive balancing ngokuvamile sishintsha indlela yokulungisa yeminyaka eyisishiyagalombili-ngo-15–20%. Ukulinganisa okwenziwayo kukhipha amandla engeziwe njengokushisa ngesikhathi sokushaja, okusebenza-kumsebenzi wokushintsha okukodwa. Izitolo{8}}eziningi ezishintshayo ezinesilinganiso samahora angu-16+ nsuku zonke zidinga ukulingana okusebenzayo kokuthi 1A–5A, zidlulisa amandla phakathi kwamaseli kunokuwachitha. Iphesenti eliqondile lincike emijikelezweni yakho yokushaja kanye nezinga lokushisa le-ambient{13}idatha esiyidonsa kusukela ezinsukwini zakho zokuqala ezingu-90 zokusebenza ukuze sicwengisise ukuqagela.
I-ROI Ngohlobo Lokusebenza
Umugqa wakho wesikhathi wenkokhelo uncike kokuhlukile okukodwa ngaphezu kwazo zonke ezinye: amahora okusebenza nsuku zonke.
-Imisebenzi yeshift emithathu (16+ amahora/ngosuku):
Inkokhelo ngokuvamile ihlala phakathi kwezinyanga eziyi-18-24. Izibalo zisebenza ngoba ususa ukushintshwa kwebhethri ngokuphelele{3}}i-forklift eyodwa, ibhethri elilodwa, ishaja eyodwa. Igumbi lebhethri liba yindawo yaphansi. Ngamanani angu-$25/sq ft wezindlu zokugcina impahla ezindaweni ezinkulu zezimpahla, ukubuyisela amamitha-skwele angu-500 kubuyisela u-$12,500 minyaka yonke ngaphambi kokonga amandla.
Ukusebenza{0}}okukodwa (amahora angu-8/ngosuku, ukuphumula kwezimpelaviki):
Inkokhelo idlulela ezinyangeni ezingama-30-36. Awulitholi inani legumbi lebhethri, ngakho-ke inzuzo incipha ukuze ishaje kahle (95–98% vs. 75–80%) kanye nokuqedwa kokulungisa.
Amayunithi angu-28-emikhumbi yokusabalalisa impahla eqandisiwe e-Central China-esebenzisa uchungechunge lwe-Linde E-ngokuvamile -35℃-kusinikeze imvume yokwabelana ngedatha ehlanganisiwe kodwa hhayi igama layo. Ngaphambi kokuguqulwa, izimoto zabo eziholayo{16}ze-asidi zaba nesilinganiso sokuhluleka kwebhethri okungahleliwe okungu-3.2 ngenyanga phakathi neziqongo zasebusika. Izinyanga eziyishumi nesishiyagalombili-zokuguqulwa: izigameko ezishisayo, ukunakekelwa kwanyanga zonke kwehle cishe ngo-$2,000, kanye nedatha egcwele ye-SOH etholakalayo ukuze isetshenziswe ngaphansi kwe-NDA. I-calculus ekugcinweni okubandayo ihlukile ngoba i-LiFePO4 igcina umthamo we-95% ku--40℃kuyilapho i-lead-acid yehla ibe ngu-30-50% -kodwa ubufakazi bokusebenza busezindaweni zokuhluleka, hhayi ishidi lokucaciswa.
Umsebenzi wakho uwela kusiphi isigaba? Xhumana nathi ngamahora akho osuku nosayizi wendiza-sizosebenzisa ukuqagela kwakho kwe-ROI phakathi namahora angu-48.
Esiyakha Ngokuhlukile
Izikhala zamanani phakathi kwabahlinzeki bebhethri ye-forklift ngokuvamile zibuyela emuva kusigaba se-BMS, hhayi ikhwalithi yeseli. Ibhethri elingu-$10,000 uma liqhathaniswa nelinye elingu-$7,000 lingasebenzisa amaseli e-CATL noma ama-EVE afanayo, kodwa izakhiwo ze-BMS zihluka kakhulu-futhi umehluko ubonakala ezingxoxweni zakho zesiqiniseko, hhayi inyanga yakho yokuqala yokusebenza.
Ukuminyana kokuqapha okushisayo:Sibeka i-thermistor eyodwa ye-NTC ngamaseli amabili, okuvumela ukutholwa kwe-thermal ebalekayo ngaphambi kokuhlukana kwezinga lokushisa kwehle. Amayunithi ebhajethi ehlela kwinzwa eyodwa module ngayinye, okudala izindawo eziyimpumputhe phakathi kwezitaki zamaseli lapho ukushisa kunqwabelana ngokushesha okukhulu. Okushiwo yinkontileka: iwaranti yethu evamile ihlanganisa izehlakalo ezishisayo ngaphandle kokudinga ubufakazi bokuthobela umqhubi. Abahlinzeki abasebenzisa imojuli{3}}yenzwa yeleveli ngokuvamile baveza okuhlukile "kwindawo yokushaja engafanele"-olimi oludlulisela isibopho kuwena uma kukhona okungahambanga kahle.
Ophenyweni oluningi lokungaphumeleli kwebhasi le-CAN esilubuyekezile, umsuka ulandelela amaphinikhodi amane amancane esixhumi se-Euro{0}}ukugqokwa kulawa maphini kubangela ukulahleka kokuxhumana okuphakathi, okubonakala njengamakhodi wephutha angahleliwe athatha amahora angu-2–4 esikhathi sokuxilonga isigameko ngasinye. I-BMS yethu yakha umzila INGABE ngezixhumi eziqinisiwe zezimboni zikalwe 10,000+ imijikelezo yokukhwelana. Ohlelweni lwemikhumbi engamayunithi angama-50 esebenzisa amashifu amabili, leso sixhumi sisodwa ngokuvamile sivimbela izingcingo zokuxilonga ezingahlelelwe eziyi-6–8 ngonyaka.
Ukunemba kwe-algorithm ye-SOC:Ukufakwa kwethu kwesihlungi se-Kalman kugcina ukunemba okungu-±3% kwe-SOC kuwo wonke umjikelezo wokushaja ogcwele. Lokhu kubalulekile uma o-opharetha bakho bexhuma ngesikhathi sekhefu-engalungile i-SOC isho ukuthi umphathi weshifu ulinganisela ngokweqile isikhathi sokusebenza esisele (ukubeka engcupheni phakathi-nokuvalwa kwendlela yendlela) noma akuthathele phansi (ukumosha amawindi okushaja akhiqizayo). Elinye lamaklayenti ethu okusabalalisa izingxenye zezimoto liphinde labala kabusha izidingo zalo zengqalasizinda yokushaja ngemva kokubona idatha yethu ye-SOC: likhansele isiteshi sokushaja sesibili esasihlelelwe, longa u-$18,000 wezindleko zokusifaka.
Lezi akuzona izinzuzo zethiyori. Sizokuxhumanisa namakhasimende akhona asebenzisa ukucupha okufanayo ukuze uthole amakholi aqondile{1}ngaphansi kwe-NDA lapho kudingeka khona.
Amaqiniso Okuthunyelwa
Umehluko wesisindo ubamba ezinye izindiza ngokungalindelekile.Amabhethri e-lithiumnesisindo esingu-40–60% esingaphansi kwamaphekhi e-asidi afanayo{{2}, okuzwakala njengenzuzo uze ubone izibalo ze-forklift counterweight zithatha isisindo sokuqala sebhethri. I-3,000 lb lead-iphakethe le-asidi elithathelwe indawo yi-1,800 lb lithium elilinganayo lidinga ukungezwa i-ballast{9}}i-tonnage ngqo iyahlukahluka ngemodeli ye-forklift, ubude bensika, kanye namandla okuphakamisa okulinganiselwe. Sibala lokhu ngesikhathi sekhotheshini futhi sifaka imininingwane ye-ballast kuphakheji yokulethwa.
Ukuhambisana kweshaja kungomunye umcabango wokuthengwa kwempahla ongaphumeleli ekusebenzeni. Amayunithi e-Lithium BMS axhumana namashaja ukuphatha amaphrofayili amanje; amashaja okuhola{{1}e-asidi aphusha ijika lokushaja elingaguquki eliziba lokhu kuxhumana. Ukufaka amabhethri e-lithium anamashaja e-lead{3}e-asidi akhona akugcini nje ngokuqeda iziqinisekiso{4}}kulimaza amaseli. Ibhajethi yokushintsha ishaja noma uqinisekise ukuthi umnikezeli webhethri uhlinzeka ngezixazululo zokushaja ezihlanganisiwe ezilinganiselwe ngeplathifomu yakho kagesi (24V, 36V, 48V, 80V).
Lokho imigqa yesikhathi eminingi yabathengisi abangakutsheli yona: -ukuguqulwa kweyunithi yezimoto ezingamayunithi angama-50 kuyiphrojekthi yekota, hhayi impelasonto ende. Amasonto amabili okuhlolwa kwamandla nokucwaninga kwamandla, amasonto amane kuya kwayisishiyagalombili okuthengwa kwempahla nokuqinisekiswa kwe-oda, usuku olulodwa kuya kwezimbili ngeyunithi ngayinye yokufakwa nokulungiswa kwe-ballast, isonto elilodwa lokuqeqeshwa komqhubi, bese kuba yinyanga yokuqapha ngaphambi kokuba amapharamitha azinze. Sakha lo mugqa wesikhathi kwinkontileka ngakho-ke alukho uhlangothi olumangazayo.
Lapho I-Lithium Ingenzi Nqondo
Senqabile imibuzo emithathu yokuguqulwa kwemikhumbi ezinyangeni eziyisithupha ezedlule-izindawo zeshifu eyodwa-ezinokusetshenziswa okuphansi, ingqalasizinda ekhona eholayo-engaphansi kweminyaka emithathu ubudala, futhi azikho izinhlelo zokunweba. Inkokhelo yelulwa ezinyangeni ezingu-48 ezedlule esimweni ngasinye, okusho ukuthi ikhasimende lingase lishintshe ama-forklift ngaphambi kokubuyisela imali yebhethri. Kungcono silahlekelwe yintengiso kunokuba sibe nereferensi yekhasimende elinendaba ye-ROI engeyinhle.
Kodwa ezindlini-ezishintshayo eziningi, izikhungo zokusabalalisa ezingu-24/7, isitoreji esibandayo, noma imikhumbi engaphezu kwamayunithi angu-10 anezinhlelo zokukhula, i-BMS{4}}inike amandla izinzuzo ezihlanganiswe ngokushesha kune-premium yangaphambili.
Izinyathelo Ezilandelayo
Sithumelele ukwakheka kwakho kwemikhumbi-imikhiqizo ye-forklift, amapulatifomu kagesi, amahora okusebenza nsuku zonke. Phakathi namahora angu-48, uzothola:
Ukuqinisekisa ukuhambisana kwephrothokholi ye-1.CAN kumodeli ngayinye
