Itumanaho rya bisi rishobora iki?
URASHOBORA gutumanaho
Igenzura ry'akarere (CAN) ni serivise itumanaho ya protocole ikoreshwa muburyo nyabwo - igihe cyo gusaba. Irashobora kohereza ibimenyetso ukoresheje kabili - kabili, umugozi wa coaxial, cyangwa fibre optique. Bitewe nibikorwa byayo bihanitse, kwiringirwa cyane, hamwe nukuri - imikorere yigihe, yabaye imwe mumashanyarazi akoreshwa cyane kwisi. CAN itumanaho nuburyo bwibanze bwitumanaho muri sisitemu yo gucunga bateri (BMS). Yemewe cyane mumashanyarazi menshi yinganda zikoresha amashanyarazi BMS haba mugihugu ndetse no mumahanga, ndetse no mubipimo byitumanaho rya BMS murugo no mumahanga. Bus za RS232 na RS485 nazo zikoreshwa mubitumanaho byimbere muri sisitemu ya BMS.
Igishushanyo 8 - 26 cyerekana sisitemu yo gucunga bateri ya bisi yamashanyarazi. Muri byo, RS232 itahura cyane cyane itumanaho hagati yubuyobozi bukuru bugenzura na mudasobwa yakira cyangwa igikoresho cyabigenewe, kandi ikuzuza igenamiterere ryibipimo bitandukanye byubuyobozi bukuru ninama ishinzwe kugenzura; RS485 itahura cyane cyane itumanaho hagati yubuyobozi bukuru nubuyobozi bugenzura, ikanarangiza ihererekanyabubasha ryamakuru ya batiri hamwe nibipimo byerekana ibimenyetso hagati ya shobuja nu mbaho; CAN itumanaho rigabanyijemo inzira ebyiri, CAN1 na CAN2. CAN1 ivugana cyane cyane nubuyobozi bukuru bwikinyabiziga kugirango irangize kohereza bateri data {9} data amakuru ajyanye nibisabwa n'ikinyabiziga cyose; CAN2 ivugana cyane nibikoresho byikinyabiziga hamwe nubushakashatsi butari ibinyabiziga kugirango bamenye kugabana amakuru ya batiri no gutanga ishingiro ryamakuru yo kugenzura.
Imiterere ya sisitemu yo gucunga bateri (BMS) muburyo bwimikorere yimodoka irerekanwa mumashusho 8 - 27. Module yo kugenzura hagati ya BMS itanga amakuru nyayo - hamwe namakuru akenewe ya bateri kubashinzwe kugenzura ibinyabiziga no kugenzura ibinyabiziga binyuze muri bisi ya CAN1, bigafasha gufata ingamba zifatika zo kugenzura neza kugirango imirimo irangire neza kandi yongere ubuzima bwa bateri. Icyarimwe, BMS (module yo kugenzura hagati) itanga amakuru arambuye yamapaki ya batiri kuri sisitemu yo kugenzura ikibaho ikoresheje bisi yihuta ya bisi ya CAN2, ikerekana amakuru yimiterere ya batiri kandi igatanga ibimenyetso byerekana amakosa, bityo igatanga ishingiro ryo kubungabunga bateri no kuyisimbuza.
Imiterere ya BMS muburyo bwo kwishyurwa bwihuse irerekanwa mumashusho 8 - 28. Amashanyarazi ahujwe kumodoka. Muri iki gihe, ikibanza kinini - umuvuduko wa bisi ya CAN2 ihuza na charger node, mugihe izindi ngingo zidahindutse. Amashanyarazi akoresha bisi ya - yihuta ya bisi ya CAN2 kugirango yumve uko igihe cya bateri ihagaze kandi ahindure ingamba zo kwishyuza kugirango agere kumuriro neza.
