Kodi Mfundo Yamagetsi Ndi Chiyani?
Mfundo Yamagetsi
Chigawo chachikulu cha galimoto yamagetsi ndi makina a batri, ndipo chimodzi mwazinthu zazikulu za batri ndi mfundo yake yamagetsi. Mapangidwe a zomangamanga a mfundo yamagetsi amapangidwa kuti akwaniritse zofunikira zomwe zimaperekedwa ndi mapangidwe a galimoto ya batri, ndipo pamene mapangidwewo atsirizidwa, amatsimikizira ntchito za batri. Mutuwu ufotokoza zambiri za mfundo zamagetsi zamakina a batri.
Kusintha kwa Magetsi
Chofunikira pakusintha kwamagetsi kwa batire kumachokera ku zofunikira za batire. Kufotokozera mwachidule zomwe galimoto imafunikira pamayendedwe a batri m'chiganizo chimodzi chosavuta: kupereka mphamvu zamagetsi pagalimoto yamagetsi mosamala komanso mosasunthika. Mawu atatu ofunika kwambiri mu chiganizo ichi ndimphamvu zamagetsi, kulamulirika,ndiotetezeka. Mphamvu yamagetsi imatanthawuza zigawo zomwe zili mkati mwa batri, monga ma module a batri, omwe angapereke mphamvu zamagetsi. Controllable imatanthawuza zigawo zomwe zili mkati mwa batri, monga Battery Control Unit (BCU), ma contactor kapena relays, ndi masensa amakono / magetsi, omwe amatha kuwongolera panopa. Safe imatanthawuza zigawo zomwe zili mkati mwa batri zomwe zimagwirizana ndi chitetezo cha machitidwe, monga fuse ndi Manual Service Disconnect (MSD). Chithunzi 9-1 chikuwonetsa makina osavuta amagetsi a batire, kuphatikiza mitundu itatu yazigawo zomwe tazitchula pamwambapa. Izi ndi monga ma module a batri, Battery Control Unit (BCU), main positive contactor, main negative contactor, fast charge positive contactor, fast charge negative contactor, pre{7}}charge relay, pre-charge resistor, current sensor, and Manual Service Disconnect (MSD) yokhala ndi fuse.
Monga tikuonera pa Chithunzi 9-1, batire ili ndi 1 Master Control Board, ma Slave Control Boards angapo, 1 MSD, ma cell angapo, high-voltage relays, low{6}}wiring harnesses, ndi zolumikizira zosiyanasiyana. Master Control Board ili ndi udindo wochita zinthu monga high-voltage relay logic control, total voltage acquisition, high-voltage connector ndi MSD connection monitoring status, kupeza panopa, charger control, kuyankhulana kwa galimoto, kutolera zidziwitso za akapolo, fault diagnosis, ndi kukweza mapulogalamu. Gulu lililonse la Slave Control Board limakonzedwa kuti lipeze magetsi a cell (0 ~ 5V) ndipo lili ndi masensa a kutentha omwe amagawidwa pagawo lililonse la batri m'bokosi.
Makina a batri omwe ali mu Chithunzi 9-1 ndi osavuta ndipo sakuphatikizanso ma subsystems monga makina oziziritsira madzi, makina otenthetsera, ndi makina owongolera kutentha.
Mfundo Zamagetsi
Chithunzi 9-2 chikuwonetsa mfundo zamagetsi zamabatire. Monga momwe tikuonera pachithunzichi, batire paketi imaphatikiza zolumikizira zabwino ndi zoyipa, zopinga -zacharge, ma pre-charge relay, MSD, kasamalidwe ka batire, ndi masensa apano. The contactors mkati kudya / pang'onopang'ono charger ndi lithiamu batire paketi amalamulidwa ndi Battery Management System (BMS), ndi logic zabwino tikulimbikitsidwa. Othandizira abwino ndi oyipa ali ndi othandizira othandizira, ndipo chizindikiro cha ndemanga chimatumizidwa ku dongosolo la kasamalidwe ka batri.
Pre-charge circuit pre-imachajisa-voltage system yagalimoto, ndipo pre-charge voltage ndi system voltage. Kupereka mphamvu kwa bolodi lalikulu la kasamalidwe ka batri kuyenera kukhala nakoPA mphamvu, mawaya amoyo ndi mawonekedwe odzutsa{0}charging. Imayendetsedwa ndi mphamvu ya ON panthawi yogwira ntchito bwino ndipo imayendetsedwa ndi gwero lamagetsi lakunja pakulipiritsa. Dongosolo loyang'anira ma batri liyenera kukhala ndi kuzindikira kukana kwa insulation ndi voltage ya mabasi ndi ntchito zowunikira pano. Kuzindikira kwapano kumatha kutengera masensa apano a shunt kapena Hall. Dongosolo la kasamalidwe ka batri liyenera kukhala ndi njira zofananira zokanira kutchinjiriza ndikuwongolera zolakwika. Zofunikira pakuzindikira kukana kwa insulation zimafotokozedwa mwatsatanetsatane muzofunikira zofananira za pepala lolowera kamangidwe ka batri. Bungwe lalikulu la kayendetsedwe ka kayendetsedwe ka batri liyenera kuzindikira kuwongolera ndi kutsimikizira zizindikiro za CC / CP / CC2 zomwe zimakwaniritsa miyezo ya dziko. Njira zolipirira ma AC ziyenera kupangidwa molingana ndi mfundo yoyendetsera woyendetsa ya Charging Mode 3 Connection Method B mulingo wadziko lonse, kulola AC kulipiritsa kudzera m'nyumba 16A soketi ndi mulu wothamangitsa wa AC. Chosinthira chokonzera ndi{12}}fuse yamagetsi yamphamvu ziyenera kukhala pakati pa batire yamagetsi. Ngati batire paketi ili ndi{14}}mabokosi ogawa, tikulimbikitsidwa kuti muyike chosinthira chokonzera zinthu ndi -fuse yamagetsi yamphamvu kwambiri pamalo apakati amagetsi pabokosi lililonse. Cholumikizira chapamwamba-chimene chili pakati pa MSD ndi chingwe cholumikizira chiyenera kupanga cholumikizira mkati mwa paketi ya batri, ndipo chizindikiro cha interlock chimazindikiridwa ndi makina owongolera batire. Cholumikizira chapamwamba{{19}chinthu chonsecho cha mphamvu yamagetsi ndi kutulutsa mphamvu zonse kwa batire ya mphamvu chimagwiritsa ntchito{{20}zolumikizira zolumikizira kale, ndi{21}}chizindikiro chapamwamba cha{21}}voltage interlock chopanga resist loop ndi Power Control Unit (PCU) ndipo mota imazindikiridwa ndi Vehicle Control Unit (VCU).
Dongosolo la kasamalidwe ka batri limagwiritsa ntchito-zomanga zaukapolo. Kulumikizana pakati pa Master Control Board ndi Slave Control Boards kumachitika kudzera pa basi ya CAN. Chithunzi 9-3 chikuwonetsa mkati mwa mabasi a CAN a kachitidwe ka batri.
Monga tikuonera pa Chithunzi 9-3, gawo lililonse lili ndi Slave Control Board. Bungwe la Slave Control Board likuphatikizidwa ndi gawoli, kulola kusinthika kosinthika, scalability, ndi kupanga ma modules ovomerezeka kuti akwaniritse zofunikira za pulatifomu. Mapangidwe amagetsi amayang'ana kwambiri kapangidwe kake kamagetsi kapamwamba ka batire, kuphatikiza mbali zachitukuko.chitetezo chamagetsi chapamwamba{{0}champhamvu chamagetsi, pre-charge circuit, high-voltage cable selection, MSD, and current sensors.
