Kwa eni ake, ogwiritsa ntchito, ndi mainjiniya omwe amayang'anira makina a batri a lithiamu, funso lobwerezabwereza limabuka: "Kodi paketi yatsopano ya batri imafunikiradi gawo lowonjezera lolinganiza?" Ngakhale kuti maselo ofanana ndi fakitale nthawi zambiri amakhala odalirika kumayambiriro kwa moyo wawo, thanzi la nthawi yayitali komanso magwiridwe antchito okhazikika a paketi iliyonse yolumikizidwa ndi mndandanda zimadalira kwambiri kusunga kusinthasintha kwamagetsi kolondola.Chowongolera Chogwira Ntchitoimagwira ntchito ngati ndalama zotsika mtengo komanso zogwira mtima kwambiri kuti iteteze kusinthasintha kumeneku panthawi yonse yogwirira ntchito ya zida. Pogwiritsa ntchito chidziwitso chenicheni chaukadaulo ndi deta yaukadaulo kuchokera kuHeltec Energy (Chengdu Heltec Energy Technology Co., Ltd.)Nkhaniyi ikufotokoza chifukwa chake ukadaulo wogwirizanitsa zinthu mwachangu ukukhala wofunikira kwambiri pakukonza magwiridwe antchito a batri, chitetezo cha makina, komanso moyo wautali pantchito zamakono zamagetsi.
Q1: N’chifukwa Chiyani Mapaketi a Mabatire a Lithium Amakumana ndi Kusalingana kwa Voltage?
Batire iliyonse ya lithiamu, mosasamala kanthu za mtundu wake woyamba, imakhala ndi "zotsatira za batire ya batire." Chochitika ichi chimachitika chifukwa palibe maselo awiri omwe ali ofanana bwino. Kusiyana kochepa, kobadwa nako mu kapangidwe ka mankhwala amkati, kulolerana kwa kupanga, kuchuluka kwa kutulutsa madzi m'thupi, komanso kukhudzidwa ndi kusinthasintha kwa kutentha kwakunja ndi kofala kwambiri m'maselo onse a lithiamu-ion ndi lithiamu iron phosphate (LiFePO₄).
Pamene batire ikuyenda ndi ma chaji ndi kutulutsa mphamvu mobwerezabwereza, kusiyana kwa ma microscopic kumeneku kumasonkhana ndikufalikira. Pamene selo yokhala ndi mphamvu yayikulu pang'ono kapena kukana kwamkati kotsika ifika pamlingo wake wapamwamba wamagetsi mwachangu kuposa oyandikana nawo, ingayambitse kudulidwa kwa chaji msanga kapena kutsekedwa koteteza. Mosiyana ndi zimenezi, panthawi yotulutsa mphamvu, selo lofooka kwambiri lingafike pamlingo wotsika wamagetsi poyamba. Pakapita nthawi, kusalingana kumeneku kumakula. Selo lofooka kwambiri—"ndodo yayifupi kwambiri" mu mbiya—limalamulira bwino ndikuchepetsa mphamvu yogwiritsidwa ntchito ya paketi yonse, zomwe zimapangitsa kuti dongosololi lisiye kugwira ntchito ngakhale maselo otsalawo akadali ndi mphamvu yochuluka yosungidwa.
Q2: Kodi Kulinganiza Zinthu Mosachita Kungokwanira? N’chifukwa Chiyani Ndikulimbikitsidwa Kugwiritsa Ntchito Kulinganiza Zinthu Mosachita Kungogwira Ntchito?
Pofuna kuchepetsa mavuto omwe amapezeka nthawi zambiri, machitidwe ambiri achikhalidwe amadalira passive balancing. Njirayi nthawi zambiri imagwiritsa ntchito ma resistors kuti ichotse mphamvu yochulukirapo ya maselo amphamvu ngati kutentha mpaka magetsi awo agwirizane ndi ena onse m'gululi. Ngakhale kuti passive balancing ndi yotsika mtengo, imakhala yochepa: imagwira ntchito pongochotsa mphamvu, zomwe sizithandiza kukonza mphamvu yonse ya makina, ndipo imapanga kutentha kosafunikira, komwe kungawononge thanzi la batri m'malo otentha kwambiri.
Mosiyana ndi zimenezi, Active Balancer—monga ma module apamwamba opangidwa ndi Heltec Energy—imagwiritsa ntchito njira zamakono zosamutsira mphamvu m'malo motaya mphamvu. Pogwiritsa ntchito ma super-capacitor apamwamba kapena ma transformer push-pull rectification feedback, zipangizozi zimasuntha mphamvu kuchokera ku maselo omwe ali ndi voltage yayikulu kupita ku omwe ali ndi voltage yochepa. Njirayi ndi yothandiza kwambiri chifukwa imasunga mphamvu yamtengo wapatali m'malo moiwononga. Ma unit apamwamba, kuphatikizapo omwe amapangidwa ndi Chengdu Heltec Energy Technology Co., Ltd., amapereka zinthu zambiri: safuna kusiyana kwa voltage yeniyeni kuti ayambe kugwira ntchito, amagwira ntchito mofanana pa paketi yonse, ndipo amatha kupereka ma currents olimba kuyambira 0 mpaka 10A kutengera kusiyana kwa kuthamanga komwe kwapezeka. Mphamvu yaukadaulo imeneyi imalola kukonza voltage yeniyeni, nthawi zambiri, zomwe zimapangitsa kuti ikhale yolondola mkati mwa 0.01V.
Q3: Kodi Kukhazikitsa Active Balancer Module Kumathandiza Bwanji Kugwira Ntchito Kwathunthu kwa Paketi?
Kuphatikiza gawo lolinganiza bwino kumasintha bwino paketi ya batri kuchokera ku gulu la maselo osiyanasiyana, omwe angakhale osiyana kukhala dongosolo lamphamvu logwirizana komanso lokhalitsa. Phindu lalikulu la Heltec Energy 5A active balancer lili mu kuthekera kwake kochitapo kanthu pochotsa zopinga zomwe zimayambitsidwa ndi kuwonongeka kwa maselo. Mwa kuonetsetsa kuti selo lililonse lomwe lili mkati mwa 8S mpaka 32S limakhalabe mkati mwa mphamvu yamagetsi yolimba, gawoli limalola dongosolo loyang'anira batri kugwiritsa ntchito mphamvu zonse zomwe zilipo za paketiyo moyenera kwambiri.
Njira yosamalira yosalekezayi imakulitsa kwambiri moyo wa ntchito ya phukusi popewa kupsinjika kwakuya kwa kayendedwe ka maselo ofooka. Kuphatikiza apo, ma module awa adapangidwa kuti athe kupirira m'malo ovuta a mafakitale ndi oyenda. Mayunitsi ambiri ali ndi zinthu zoteteza monga chitetezo chanzeru kutentha kwambiri, njira zogona zotsika mphamvu kuti zisatuluke kwambiri panthawi yopanda ntchito, komanso zokutira zapadera zitatu zomwe zimapereka chitetezo chofunikira ku chinyezi, fumbi, ndi zinthu zowononga. Mwa kusunga mphamvu zamagetsi nthawi zonse, kupsinjika kwa maselo pawokha kumachepetsedwa, zomwe zimapangitsa kuti makina azigwira ntchito bwino, mokhazikika, komanso modalirika pa ntchito zosiyanasiyana, kuphatikiza magalimoto amagetsi, makina osungira mphamvu osasuntha, ndi magetsi a mafakitale.
Q4: Kodi Kukhazikitsa Kukufunika Kapena Kuyimitsidwa Pa Nthawi Ziti?
Kudziwa ngati kuyika active balancer nthawi zambiri kumadalira momwe imagwiritsidwira ntchito, kupsinjika kwa chilengedwe, ndi momwe imagwiritsidwira ntchito. Kwa makina omwe nthawi zambiri amakhala ndi nkhawa yayikulu yogwirira ntchito, monga ma pack osungira mphamvu okhala ndi ma 4S kapena ma series apamwamba, ma pack akale a batri komwe ma cell angakhale atapanga ma profiles osiyana, kapena ma settings omwe nthawi zambiri amagwira ntchito ndi ma voltage differentials opitilira 30mV, kukhazikitsa kumalimbikitsidwa kwambiri. Zochitika izi zimapindula nthawi yomweyo ndi kukhazikika ndi chitetezo chomwe chimaperekedwa ndi gawo lolinganiza. Mosiyana ndi izi, ngati makina agwiritsa ntchito cell pack yatsopano, yogwirizana bwino ndipo imagwira ntchito nthawi yochepa kwambiri, yopanda mphamvu, kukhazikitsa nthawi yomweyo sikungakhale kofunikira kwambiri, ngakhale kuyang'anira mwachangu kumakhala koyenera kwambiri pamene paketi ikukalamba.
Mapeto
Kukhazikika kwa batire ya lithiamu ndikofunikira kwambiri pakugwira ntchito kwake kwa nthawi yayitali komanso kukhala ndi ndalama zokwanira. Pothana ndi zomwe zimayambitsa kusalingana kwa maselo kudzera mu kusamutsa mphamvu kwapamwamba, ukadaulo woperekedwa ndi Heltec Energy umathandiza ogwiritsa ntchito kukulitsa ndalama zawo, kukonza chitetezo cha ntchito, ndikuwonjezera moyo wa zida zawo. Kaya kukhala ndi magalimoto amalonda aukadaulo kapena makina osungira mphamvu achinsinsi, kuyang'anira magetsi mwachangu ndi njira yomveka bwino komanso yothandiza yopezera thanzi labwino la batire.
Kwa iwo omwe akufuna kumvetsetsa zofunikira zenizeni zoyendetsera batri yapadera kapena omwe akufuna kudziwa zambiri zaukadaulo wamakonzedwe osiyanasiyana a ma cell, zinthu zambiri komanso zambiri za malonda zitha kupezeka pahttps://www.heltec-energy.com/
