Kodi chipangizo chogawa mphamvu zamagetsi chapamwamba kwambiri pamagalimoto ndi chiyani?
Chipinda chogawa magetsi amphamvu kwambiri (PDU) cha magalimoto ndi gawo lofunika kwambiri mu dongosolo la magetsi amphamvu kwambiri la magalimoto atsopano, lomwe limayang'anira kwambiri kugawa magetsi ndi kuyang'anira kuti zitsimikizire kuti zida zamagetsi amphamvu kwambiri zikugwira ntchito bwino komanso mokhazikika.
Ntchito zazikulu
Youdaoplaceholder0 Kugawa ndi kuyang'anira mphamvu : Gawani mosamala mphamvu yamagetsi yamphamvu kwambiri ku zida zosiyanasiyana zamagetsi, monga ma drive motors, makina ochaja, ndi zina zotero.
Youdaoplaceholder0 charge ndi discharge control : Amayang'anira njira yolipirira ndi discharge ya high-voltage system, kuphatikizapo chitetezo cha overload, short-circuit protection ndi high-voltage sampling function.
Youdaoplaceholder0 low-voltage control : kuwongolera mphamvu ndi kuyang'anira momwe zinthu zilili ndi mphamvu zamagetsi ambiri kudzera m'mabwalo otsika magetsi.
Kapangidwe ka Youdaoplaceholder0 kochotsa kutentha : Ma PDU ena amagwiritsa ntchito njira zoziziritsira madzi kapena zoziziritsira mpweya kuti atsimikizire kuti kutentha kumafunikira pazinthu zamagetsi amphamvu.
Makhalidwe a kapangidwe kake
PDU imatha kuphatikiza ntchito monga ma module osinthira a DC-DC, ma module a OBC ochaja, ndi BMS main control, zomwe zimapangitsa kuti pakhale kapangidwe kogwirizana kwambiri. Mwachitsanzo, ma module atatu mu chimodzi ndi anayi mu chimodzi amatha kuphatikiza mayunitsi ambiri ogwira ntchito kuti akwaniritse zosowa za mitundu yosiyanasiyana ya magalimoto.
Chipangizo chogawa magetsi amphamvu kwambiri (PDU) cha magalimoto ndicho chida chachikulu chowongolera makina amphamvu kwambiri m'magalimoto atsopano, makamaka pogwira ntchito zogawa magetsi ndi chitetezo. Ntchito zake zazikulu ndi izi:
Kugawa mphamvu zamagetsi zamagetsi amphamvu kwambiri
PDU imagawa mphamvu yamagetsi yamphamvu (300-800V) yotuluka ndi batire yamagetsi kuzinthu zofunika monga mota yoyendetsa, chojambulira chamkati (OBC), chosinthira cha DC/DC, ndi compressor yamagetsi yoziziritsira mpweya. Mwachitsanzo, chowongolera cha mota yoyendetsa chimawerengera pafupifupi 60% ya mphamvu yamagetsi, ndipo zotsalazo zimagawidwa ku machitidwe othandizira monga kuchaja ndi kutentha.
Njira yotetezera chitetezo
Kuphatikizapo overcurrent, short circuit, overvoltage ndi chitetezo cha overheat:
Chitetezo cha Youdaoplaceholder0 overcurrent : Pamene mphamvu yamagetsi ipitirira 120% ya mtengo wovomerezeka kwa masekondi awiri, cholumikizira chachikulu chimachotsedwa ndipo fuse imawombedwa
Chitetezo cha Youdaoplaceholder0 Short-circuit : Pamene impedance ili yotsika kuposa 100mΩ, dera limadulidwa mu microseconds
Youdaoplaceholder0 Chitetezo cha kutentha kwambiri : Pamene kutentha kwa busbar yamkuwa kupitirira 110℃, pang'onopang'ono kumachepetsa katundu kapena kudula mphamvu
Kuzindikira kutchinjiriza kwa Youdaoplaceholder0 : kumatha kuzindikira chiopsezo cha kulephera kwa kutchinjiriza <500Ω/V ndikuyambitsa alamu
Kuphatikiza ndi kuwongolera dongosolo
Imaphatikiza gawo losinthira la DC/DC, gawo lowongolera chaji ndi ntchito yayikulu yowongolera ya BMS, ndipo imathandizira kapangidwe ka modular. Malangizo a VCU amalandiridwa kudzera mu basi ya CAN kuti akwaniritse kuwongolera kwa sequence ya power-on/power-off ya circuit ya high-voltage (nthawi yoyankha <50ms), ndipo njira yogawa mphamvu imasinthidwa mosinthika (monga kuyika patsogolo kutseka kwa katundu wosafunikira panthawi yochaja).
Zizindikiro za magwiridwe antchito
Kugawa bwino kwa ≥98% (kuchepa kwa katundu wovomerezeka)
Mphamvu yotetezera kutentha imatha kupirira 2500V AC kwa masekondi 60 popanda kuwonongeka
Moyo wa makina a relay yamagetsi okwera ndi ma cycle opitilira 100,000
Imathandizira ntchito yofananiza katundu wosinthika (kuchepetsa kugwiritsa ntchito mphamvu ndi 5-8%)
Zolakwika mu gawo logawa magetsi amphamvu kwambiri m'galimoto nthawi zambiri zimayambitsa machitidwe amagetsi osazolowereka, kusokonekera kwa chaji kapena kuwonongeka kwa zida zamagetsi, zomwe zimawonetsedwa motere:
Chochitika cholakwika
Youdaoplaceholder0 Kulephera kwa makina amagetsi : Galimoto silingathe kuthamangitsa bwino, ndipo liwiro lalikulu ndi lochepa (mwachitsanzo, liwiro lomwe lili mu kesiyo ndi 40km/h yokha)
Youdaoplaceholder0 Kuchaja kosayenera : Kuchaja kwa AC/DC kwasokonekera kapena sikungayambike (onani zolakwika mu mzere wa cholumikizira cha chaji kapena sensa)
Youdaoplaceholder0 Alamu ya chida : Ikuwonetsa "Vuto lalikulu la dongosolo lamagetsi" kapena "vuto la dongosolo lamagetsi"
Youdaoplaceholder0 Chitetezo cha zigawo zamagetsi : Dongosololi limadula lokha dera lamagetsi amphamvu kuti lisawonongedwenso (monga zowongolera mota, mabatire amagetsi, ndi zina zotero)
Zomwe zimayambitsa
Youdaoplaceholder0 high-voltage interlock circuit open circuit : zizindikiro zosazolowereka zowunikira zimayambitsa kutsekedwa kwa dongosolo (monga kukhudzana koyipa kwa mzere, kugwedezeka kwa chosweka cha circuit)
Zolakwika zamkati mwa bokosi logawa: cholumikizira cha bokosi logawa lamagetsi okwera chimakakamira, ndipo kuzindikira kutayikira sikutha
Youdaoplaceholder0 Kuzungulira pang'ono kapena kupitirira muyeso : kuwonongeka kwa gawo loteteza kutentha la waya wamagetsi amphamvu kwambiri kumayambitsa kuzungulira pang'ono pansi
Njira zodziwira matenda
Youdaoplaceholder0 Werengani khodi yolakwika : Pezani khodi yolakwika yeniyeni (monga P1E0300, B042900) kudzera mu decoder
Mayeso a mafunde a chizindikiro cha Youdaoplaceholder0 : Yang'anirani ngati chizindikiro cha duty cycle cha high-voltage interlock circuit ndi chachibadwa (zida zaukadaulo zimafunika)
Kutsimikizira kwa mayeso a dera la Youdaoplaceholder0 : Yang'anani momwe zigawo zamagetsi zimayankhira (monga momwe magetsi alili pa chowongolera cha mota) muzochitika zoyeserera za cholakwika
Ndikofunikira kulankhulana ndi bungwe losamalira akatswiri kuti akayesedwe magetsi amphamvu kuti apewe ngozi zomwe zingachitike chifukwa chodzisokoneza.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
