Uburyo bwo guhitamo 48V LiFePO4 BMS yo kubika bateri mu rugo

Guhitamo sisitemu yo gucunga bateri (BMS) yo kubika ibikoresho mu rugo ya LiFePO4 yo mu bwoko bwa 48V bitangirira ku gishushanyo cya bateri—ntabwo ari izina ry'igicuruzwa. Igenzura ry'ingenzi ni umubare w'uturemangingo turi mu buryo butandukanye, ingufu zisohora umuriro n'amashanyarazi, itumanaho rya inverter, imiterere y'ubushyuhe, na gahunda iyo ari yo yose yo guhuza udupaki icyarimwe.

Iyi mfashanyigisho ifasha abakora bateri n'abahuza ububiko bw'ingufu gutegura ibyo bisabwa no kumenya amahitamo ya BMS yo kubikamo ibikoresho mu rugo ya DALY akeneye isuzuma ryinshi rya tekiniki.

“16S” bivuga uturemangingo 16 cyangwa amatsinda y’uturemangingo ahujwe mu buryo bukurikiranye. Hakoreshejwe voltage isanzwe ya LiFePO4 y’uturemangingo ya 3.2V, voltage y’uturemangingo ya paki ni 16 × 3.2V = 51.2V. Utwo dupaki dukunze kwitwa sisitemu za 48V; “48V” yonyine ntabwo igaragaza umubare w’uturemangingo.

Emeza shimi y'uturemangingo, umubare w'uruhererekane rw'uturemangingo, imipaka y'amashanyarazi y'uturemangingo, n'urwego rw'amashanyarazi akoreshwa na batiri mbere yo guhitamo BMS. Hari inyigisho rusange ya DALY 16S yo gukwirakwiza insinga irahari kugira ngo usobanukirwe uburyo bwo kumenya uruhererekane rw'uturemangingo, ariko ntabwo ari ikintu gisimbura imbonerahamwe y'insinga itangwa na moderi ya LK cyangwa LM nyayo.

Gereranya ingufu zisohoka ku ruhande rwa batiri uvuye ku mbaraga zisohoka za AC zihoraho za inverter, ingufu nke za bateri zijyanye nayo, n'ubushobozi bwa inverter: ingufu zisohoka za DC (A) ≈ imbaraga zisohoka za AC (W) ÷ [imbaraga zisohoka za bateri (V) × imikorere myiza].

Urugero, 5.000W ÷ (48V × 0.90) ≈ 116A. Ku muvuduko muto wa batiri wa 44V, ibarwa rimwe ritanga hafi 126A. Iyi mibare igaragaza impamvu icyapa cya 48V kidahagije; nta n'umwe muri bo ugaragaza amanota ya nyuma ya BMS.

Reba imbaraga zihoraho za inverter n'igihe cyo kwiyongera kw'amashanyarazi, voltage ntoya ya bateri ikora, igipimo cyemewe cyo gusohora umuriro mu ipaki, amanota ahoraho ya BMS n'ay'umuvuduko, ubushyuhe bw'imikorere, n'imiterere y'aho ifungirwa. Reba ukwayo imbaraga ntarengwa zo gushyushya umuriro uva kuri charger cyangwa inverter n'ibipimo bya selile ya bateri. Ntugatekereze ko guhitamo amanota akurikiraho yo hejuru y'amashanyarazi bihita byemeza ko akwiriye.

Emeza niba inverter ikeneye umuyoboro w'itumanaho rya batiri cyangwa ishobora gukora hakurikijwe ingamba zo kugenzura zishingiye ku muyoboro w'amashanyarazi zemejwe ukwazo. CAN (Umuyoboro w'Agace k'Umuyoboro w'Abagenga) na RS485 ni imiyoboro y'itumanaho; guhuza imiyoboro ntabwo bigaragaza ko BMS na inverter bikoresha ubutumwa bumwe cyangwa amategeko amwe yo kugenzura.

Tanga igikoresho cya inverter n'icyitegererezo nyacyo, protocole na verisiyo bikenewe, hamwe n'inyandiko iyo ari yo yose ihari yo guhuza. Saba DALY kwemeza ko hari ubufasha cyangwa ko bishoboka ko habaho guhindura protocole yihariye kuri configuration ya BMS. Ntugafate imiterere ya CAN/RS485 isanzwe nk'igisubizo cyo guhuza.

Reba ubushyuhe bwemewe n'uruganda rukora imashini zishyushya no gusohora umuriro hamwe n'ahantu hateganyijwe gushyirwa. Imipaka yo gushyushya mu gihe cy'ubukonje n'ibikenewe byose byo gushyushya bigomba gusuzumwa hakurikijwe imashini nyazo na sisitemu. Ntugatekereze ko DALY BMS runaka irimo uburyo bwo kugenzura ubushyuhe keretse byemejwe kuri iyo miterere.

Guhuza utunyangingo bishobora gufasha gucunga itandukaniro riri hagati y’utunyangingo duhujwe n’uruhererekane, ariko ntibishobora gusimbura guhuza utunyangingo cyangwa gukosora imiterere idakwiye ya bateri. Emeza niba BMS iteganyijwe ikoresha uburinganire butari mu buryo busanzwe cyangwa imiterere y’uburyo bwo guhuza imikorere butari mu buryo busanzwe kandi ugenzure imiterere y’ubu n’imikorere y’uburyo nyabwo.

Niba ishyirwaho rikoresha bateri nyinshi icyarimwe, emeza BMS ishyizwe kuri buri paki, imiterere yo gusangira no kurinda umuriro, guhuza paki na voltage, itumanaho, gutandukanya amakosa, no gushyiraho uburyo bwo kuyikoresha. Umubare ntarengwa wavuzwe w'amapaki ajyanye ntabwo ari ikimenyetso cy'uko uruvange rw'amapaki na inverters bizakorana neza.

Saba isuzuma ry’urwego rwa sisitemu kugira ngo urebe imiterere ijyanye. Uburyo burambuye bwo gukwirakwiza insinga no gushyiraho porogaramu bugomba kuba buri mu bitabo by’amabwiriza agenga ibicuruzwa n’inyandiko zigena imiterere ya sisitemu, ntabwo ari muri iyi ncamake y’uburyo bwo guhitamo.

Urupapuro ruheruka rwo kugereranya DALY yo mu gisekuru cya 4 cya LK/LM rwatanzwe kuri iyi ngingo rugaragaza imiterere ya LiFePO4 8S/16S hamwe n'amahitamo akurikira yo gushyushya/gusohora umuriro uhoraho. Aya ni amanota y'abakandida, ntabwo ari uburyo bwo guhuza na inverter runaka.

LK: Isuzuma rya 100A ryo gushyushya/gusohora umuriro rihoraho. LM: Isuzuma rya 150A cyangwa 200A ryo gushyushya/gusohora umuriro rihoraho. Urupapuro rwo kugereranya rugaragaza kandi uburyo bwo guhuza imikorere; ntugatekereze ko buri gice kirimo.

Ku gishushanyo mbonera giteganijwe gukurura hafi 116A munsi y’uburyo bumwe bwo gukora, amanota ahoraho ya 100A ntabwo yagera kuri iyo mimerere iteganijwe. Amahitamo ya 150A ashobora kuba akwiye gusuzumwa, ariko guhitamo kwa nyuma bisaba kugenzura ingufu nkeya z’amashanyarazi, ingano y’amashanyarazi, amashanyarazi, imiterere y’ubushyuhe, imiterere, n’urupapuro rw’amakuru nyayo rw’ibicuruzwa.

Ku isuzuma rya tekiniki rya mbere, tanga: shimi ya bateri n'umubare w'uruhererekane (urugero, 16S LiFePO4); ubushobozi bwo gupakira (Ah); imipaka y'amashanyarazi ya selile; uruganda rwa inverter/icyitegererezo n'imbaraga zihoraho/zizamuka; ingufu zisabwa zo gusharija no gusohora umuriro zihoraho; ingufu zidasanzwe n'igihe kirekire; ibisabwa mu itumanaho; ubushyuhe buteganijwe gushyirwamo; umubare w'amapaki ajyanye; n'ingano y'ibikoresho biteganijwe.

DALY ishobora gukoresha aya makuru kugira ngo isuzume imiterere ikwiye ya LK/LM, imenye amakuru yose akenewe, kandi iganire ku nyandiko za tekiniki zihari n'amahitamo y'ibiciro. Guhitamo icyitegererezo cya nyuma n'inkunga ya protocole bigomba kwemezwa kugira ngo bigenzurwe.
