Kapangidwe ka makina ochapira a DC okhala ndi mfuti ziwiri

Nkhaniyi ikufotokoza za kapangidwe ka magetsi kamulu woyatsira wa DC wokhala ndi mfuti ziwiri, kufotokoza mfundo zogwirira ntchito za mfuti imodzi ndimilu ya magalimoto amagetsi okhala ndi mfuti ziwiri, ndikupereka njira yowongolera zotuluka kuti zigwirizane ndi kusinthana kwa ndalamasiteshoni yochapira mfuti ziwiri.

Kuti akonze nzeru ndi momwe angayankhire nthawi yeniyeni poyendetsa chaji, nkhaniyi ikutchulanso njira yopangira makina owongolera chaji kutengera chip chachikulu cha STM32F407 chokhala ndi Cortex M4 core ndi makina ogwiritsira ntchito a FreeRTOS omwe ali mkati.

Kapangidwe ka Zomangamanga

Chatsopano ichi chikuwonetsa kapangidwe ka mfuti ziwiriChojambulira cha DC EV, yokhala ndi chowongolera chachikulu, gawo lamagetsi, chiwonetsero cha mawonekedwe a munthu ndi makina, chowerengera khadi la IC, mita yamagetsi yanzeru,cholumikizira cha AC, Wothandizira wa DC, chosokoneza ma circuit, choteteza ma surge, ndi magetsi awiri a 12V DC. Chithunzi chonse cha magetsi cha mulu wochapira chikuwonetsedwa pansipa. Kapangidwe ka magetsi pakati pa mulu wochapira ndi mfuti za A ndi B kakugwirizana ndi muyezo wadziko lonse wa ma DC charging interfaces a zida zochapira zamagetsi zamagalimoto amagetsi.

Mfundo yogwirira ntchito

Malo ochapira ndi mfuti ziwiriMalo ochapira a DC, pogwiritsa ntchito ma module 10 amphamvu olumikizidwa motsatizana, opangidwa ndi njira ziwiri zowongolera kuchaja: kuchaja kolinganiza ndi kuchaja motsatizana.

Kuchaja molingana: Mfuti zonse ziwiri A ndi B zimachaja nthawi imodzi, ndi ma module amphamvu osapitirira 5 omwe amachaja kuchokera ku mfuti iliyonse.

Kuchaja mosasunthika: Pamene mfuti imodzi yokha ikugwira ntchito, ma module amphamvu okwana 10 amatha kuchaja.

Ma module amagetsi amalandira mphamvu yamagetsi ya magawo atatu ya AC, yolumikizidwa ku choteteza ma surge, mita yamagetsi ya magawo atatu ya AC, ndi cholumikizira cha AC. Ma module amagetsi amatulutsa mphamvu ya DC. Batani loyimitsa mwadzidzidzi limaphatikizidwanso pa cholowera, zomwe zimathandiza chitetezo cha kuyimitsa mwadzidzidzi podula cholowera cha magawo atatu. Chowongolera chachikulu chimalumikizana ndi ma module amagetsi kudzera mu basi ya CAN kuti chisinthane malamulo owongolera kutulutsa, ndipo ma module amagetsi amalumikizidwanso kudzera mu basi ya CAN. Siteshoniyi ili ndi magetsi awiri a 12V DC: imodzi yolumikizidwa ku ma pini a A+ ndi A a mfuti yochapira kuti ipereke mphamvu yothandizira yamagetsi yochepa, ndipo inayo imayendetsa chiwonetsero cha mawonekedwe a anthu.

Kapangidwe ka makina owongolera akuluakulu

A. Chithunzi cha Ma Block Ogwira Ntchito a System

Chithunzi chachikulu cha block ya dongosolo lowongolera chikuwonetsedwa pansipa. Chip yayikulu yowongolera ya dongosololi ndi STM32F407ZGT6, yomwe ili ndi ma interfaces ambiri a peripheral: 2 CAN, 4 USART, 2 UART, 1 Ethernet interface, ndi zina zotero, zomwe zimakwaniritsa zofunikira zoyambira za mawonekedwe a dongosolo lowongolera ma pile kuti ziwongolere ma peripheral monga ma power module, ma smart meter, ma IC card reader, ndi ma touch screen.

B. Kapangidwe ka Main Control System Hardware Circuit

Izi zikuphatikizapo kapangidwe ka ma circuit olumikizira mabasi a RS232, RS485, ndi CAN.
