EMU1203-12V Lithium LFP Ibhethri Pack BMS
Isingeniso Somkhiqizo
(1) Ukutholwa komthamo weseli nebhethri
Ukuqoqwa kwesikhathi sangempela kanye nokuqapha amandla kagesi eqembu elilodwa lamaseli angu-4 ukuze kuzuzwe ukugcwala kweseli kanye ne-alamu engaphansi kwe-voltage nokuvikelwa.Ukunemba kokutholwa kwamandla kagesi kweyunithi eyodwa kungu-≤±20mV ku- -20~70℃, futhi ukunemba kokutholwa kwamandla kagesi kwePACK kungu-≤±0.5% kokuthi -20~55℃.
(2) Ukulinganisa kweseli eyodwa okuhlakaniphile
Amaseli angalingani angalinganiswa ngesikhathi sokushajwa noma okubekwe eceleni, okungathuthukisa ngempumelelo isikhathi sokusebenzisa ibhethri nempilo yomjikelezo.
(3) Umsebenzi wokushaja kwangaphambili
Umsebenzi wangaphambi kokushajwa ungaqalwa ngokushesha lapho amandla evuliwe noma ishubhu yokukhipha ivuliwe.Isikhathi sangaphambi kokushaja singasethwa (1S ukuya ku-7S), esisetshenziselwa ukubhekana nezimo ezihlukahlukene zomthwalo we-capacitive nokugwema ukuvikelwa kokukhishwa kwe-BMS kwe-short circuit.
(4) Amandla ebhethri nezikhathi zomjikelezo
Bala umthamo webhethri osele ngesikhathi sangempela, qedela ukufundwa kwesamba sokushaja kanye namandla okulikhipha ngesikhathi esisodwa, futhi ukunemba kwesilinganiso se-SOC kungcono kuno-±5%.Inomsebenzi wokubala inani lemijikelezo yokushaja nokukhipha.Uma umthamo wokukhipha oqongelelekayo wephakethe lebhethri ufinyelela ku-80% womthamo ogcwele osethiwe, inani lemijikelezo likhuphuka ngowodwa, futhi inani lokusetha ipharamitha yomjikelezo webhethri lingashintshwa ngekhompyutha yokusingatha.
Umongo webhethri, indawo kanye nokutholwa kwezinga lokushisa kwamandla: amazinga okushisa amabhethri angu-2, izinga lokushisa eli-1 le-ambient, kanye nezinga lokushisa lamandla angu-1 kukalwa nge-NTC.Ukunemba kokutholwa kwezinga lokushisa ngu-≤±2℃ ngaphansi kwezimo -20~70℃.
(5) RS485 ukuxhumana esibonakalayo
I-PC noma i-front-end ehlakaniphile ingabona ukuqapha idatha yebhethri, ukulawula ukusebenza kanye nokusetha kwepharamitha nge-telemetry yokuxhumana ye-RS485, ukusayinda okukude, ukulungiswa kwerimothi, isilawuli kude neminye imiyalo.
Kuyini Ukusetshenziswa?
Inemisebenzi yokuvikela nokuthola kabusha efana ne-voltage eyodwa phezu kwe-voltage/ngaphansi, isamba se-voltage ngaphansi kwe-voltage/overvoltage, ukushaja/ukuphuma ngaphezulu kwamanje, izinga lokushisa eliphezulu, izinga lokushisa eliphansi kanye nesekhethi emfishane.Thola ukukala okunembile kwe-SOC kanye nezibalo zesimo sezempilo se-SOH ngesikhathi sokushaja nokukhipha.Thola ibhalansi kagesi ngesikhathi sokushaja.Ukuxhumana kwedatha kwenziwa nomsingathi ngokuxhumana kwe-RS485, futhi ukucushwa kwepharamitha nokuqapha idatha kwenziwa ngokusebenzisana kwekhompyutha ephezulu ngokusebenzisa isofthiwe yekhompyutha ephezulu.
Izinzuzo
1. Umsebenzi wesitoreji:Ucezu ngalunye lwedatha lugcinwa ngokuvumelana nokushintsha kwesimo se-BMS.Idatha yokulinganisa phakathi nenkathi ethile yesikhathi ingagcinwa ngokusetha isikhawu sesikhathi sokurekhoda.Idatha yomlando ingafundwa kukhompuyutha yokusingatha futhi ilondolozwe njengefayela.
2. Umsebenzi wokushisisa:Inikeza isikhombimsebenzisi sokushisa.Idizayini yesekethe eyingqayizivele isebenzisa ukuphuma kokushisa komthombo wamandla wokulayisha, okuphuma ngokuqhubekayo okungu-3A wamanje futhi kungafinyelela izinga lokushisa eliphezulu elingu-5A.
3. Umsebenzi wokushajwa kusengaphambili:Thuthukisa ukuqina kokushajwa kwebhethri, gwema amandla kagesi aphezulu ngokushesha futhi uvikele ukuphepha komuntu siqu nokomkhiqizo.Indlela yokushajwa ngaphambili eyingqayizivele ivikela ibhethri ngempumelelo futhi inweba impilo yesevisi yephakethe lebhethri.
4. Umsebenzi wokuxhumana (CAN+485):I-interface efanayo iyahambisana nokuxhumana kwe-RS485 kanye nokuxhumana kwe-CAN, okwenza kube nezinjongo eziningi.
