Pamene njira zosungira mphamvu, mabatire a lithiamu, njira zamagetsi a dzuwa, ndi ukadaulo wamafakitale wodzipangira okha zikupitilizabe kusintha, kulumikizana kodalirika pakati pa zida kwakhala kofunika kwambiri kuposa kale lonse. Njira ziwiri zolumikizirana zomwe zimagwiritsidwa ntchito kwambiri mumachitidwe oyang'anira mabatire (BMS)Ndipo ntchito zosungira mphamvu ndi CAN Bus ndi RS485.
Ngati mukusankha njira yosungira mphamvu ya batri, inverter, kapena njira yosungira mphamvu, kumvetsetsa kusiyana pakati pa CAN ndi RS485 kungakuthandizeni kukwaniritsa kugwirizana, kuyang'anira, komanso magwiridwe antchito a dongosolo.
Munkhaniyi, tiyerekeza CAN ndi RS485, tifotokoza momwe zimagwirira ntchito, ndikuthandizani kudziwa njira yolumikizirana yomwe ili yoyenera pulogalamu yanu.
Kodi basi ya CAN ndi chiyani?
CAN (Network ya Malo Olamulira)ndi njira yolumikizirana yomwe idapangidwa koyamba ndi Bosch yamapulogalamu a magalimoto. Imalola zipangizo zingapo kulankhulana pa netiweki yogawana popanda kugwiritsa ntchito kompyuta.
Masiku ano, CAN Bus imagwiritsidwa ntchito kwambiri m'mabungwe awa:
- ⭐Makina a batri a Lithium
- ⭐Makina osungira mphamvu ya dzuwa
- ⭐Magalimoto amagetsi (ma EV)
- ⭐Kuchita zokha kwa mafakitale
- ⭐Machitidwe oyendetsera mphamvu mwanzeru
Kulankhulana kwa CAN kumathandiza kusinthana deta nthawi yeniyeni pakati pa mabatire, ma inverter, ma charger, ndi nsanja zowunikira.
Ubwino wa basi ya CAN:
- √Liwiro lolankhulana mwachangu
- √Kudalirika kwambiri
- √Kuzindikira ndi kukonza zolakwika bwino kwambiri
- √Imathandizira maukonde ovuta okhala ndi zida zambiri
- √ Kutumiza deta nthawi yeniyeni
Kodi RS485 ndi chiyani?
RS485 ndi muyezo wolumikizirana wotsatizana womwe wapangidwira kulumikizana kwakutali komanso kwa mafakitale. Umalola zida zingapo kulumikizana kudzera pa waya wopindika umodzi.
RS485 imapezeka kwambiri mu:
- ♦Machitidwe osungira mphamvu ya batri (BESS)
- ♦Ma inverter a dzuwa
- ♦Zipangizo zowongolera mafakitale
- ♦Mamita anzeru
- ♦Makina odzipangira okha
Mosiyana ndi CAN, RS485 imayang'ana kwambiri pa kulumikizana kokhazikika kwa mtunda wautali ndipo nthawi zambiri imagwiritsidwa ntchito ndi ma protocol monga Modbus RTU.
Ubwino wa RS485:
- ♠Mtunda wautali wotumizira
- ♠Mtengo wotsika woyika
- ♠Kapangidwe kosavuta ka netiweki
- ♠Kukana mwamphamvu phokoso lamagetsi
- ♠Kuphatikiza kosavuta ndi zida zamafakitale
CAN vs RS485: Kusiyana Kwakukulu
Tebulo lotsatirali likuwonetsa kusiyana kwakukulu pakati pa CAN ndi RS485.
| Mbali | Basi ya CAN | RS485 |
| Mtundu Wolumikizirana | Ndondomeko + Gawo Lathupi | Muyezo wa Gulu Loyenera |

CAN vs RS485 mu Lithium Battery Systems
Kwamakina osungira mphamvu ya batri ya lithiamu,Kulumikizana pakati pa makina oyendetsera batri ndi inverter ndikofunikira kwambiri.
Kulankhulana kwa CAN kwa Mabatire
- ♥CAN nthawi zambiri imakondedwa pamene:
- ♥Kuwunika batri nthawi yeniyeni ndikofunikira
- ♥Ma module ambiri a batri amalumikizidwa nthawi imodzi
- ♥Kuphatikizika kwapamwamba kwa inverter kukufunika
- ♥Kudalirika kwambiri kwa dongosolo ndikofunikira
Mitundu yambiri yotchuka ya inverter imathandizira kulumikizana kwa CAN chifukwa imapereka zambiri mwatsatanetsatane za batri, kuphatikizapo:
- ♣Boma Loyang'anira (SOC)
- ♣Mkhalidwe wa Zaumoyo (SOH)
- ♣Voteji
- ♣Zamakono
- ♣Kutentha
- ♣Mkhalidwe wa alamu
Kulankhulana kwa RS485 kwa Mabatire
- ▲RS485 ikadali yotchuka chifukwa:
- ▲Imathandizira kuti chingwe chizigwira ntchito kwa nthawi yayitali
- ▲Imagwirizana kwambiri ndi zipangizo zamafakitale
- ▲Amapereka njira zolumikizirana zotsika mtengo
- ▲Imagwira ntchito bwino ndi makina owunikira omwe amagwiritsa ntchito Modbus
Kwa ambirimalo osungiramo zinthu zogwiritsa ntchito mphamvu ya dzuwa m'nyumba ndi m'mabizinesi, RS485 imapereka magwiridwe antchito okhazikika komanso odalirika olumikizirana.
Ndi chiyani chabwino: CAN kapena RS485?
Palibe wopambana kotheratu. Chisankho choyenera chimadalira pulogalamu yanu yeniyeni.
Sankhani CAN Ngati:
- ♥Mukufuna kusinthana deta mwachangu
- ♥Dongosolo lanu limafuna kuyang'aniridwa nthawi yeniyeni
- ♥Mabatire angapo amagwira ntchito nthawi imodzi
- ♥Mumagwiritsa ntchito ma inverters apamwamba a hybrid
Sankhani RS485 Ngati:
- ♥Mtunda wolumikizana ndi wautali
- ♥Dongosolo lanu limagwiritsa ntchito Modbus RTU
- ♥Kuphweka ndi mtengo wake ndi zinthu zofunika kwambiri
- ♥Kuphatikiza mafakitale ndikofunikira
Mu njira zambiri zamakono zosungira mphamvu, njira zonse ziwiri zolumikizirana zimaperekedwa kuti zigwirizane bwino.
Chifukwa Chake Ma Protocol Olumikizirana Ndi Ofunika Pakusungira Mphamvu ya Dzuwa
Kulankhulana ndi batri sikungokhala chinthu chongofuna kuchitidwa. Kumakhudza mwachindunji:
- ♠Kugwiritsa ntchito bwino ndalama
- ♠Moyo wa batri
- ♠Chitetezo cha dongosolo
- ♠Mphamvu zowunikira patali
- ♠Kusamalira mphamvu mwanzeru
Njira yolumikizirana yolumikizidwa bwino imalola inverter ndi batri kugwira ntchito limodzi bwino, kuthandiza ogwiritsa ntchito kugwiritsa ntchito mphamvu ya dzuwa bwino komanso kuchepetsa ndalama zogwirira ntchito.
Mabatire a Lithium a YouthPOWER Amathandizira CAN ndi RS485
At Achinyamata, tikumvetsa kuti kugwirizana kwa ma inverter ndi nkhani yaikulu kwa okhazikitsa magetsi a dzuwa, ogulitsa, ndi opanga mapulojekiti.
Mabatire athu apamwamba a LiFePO4 apangidwa ndi njira zolumikizirana za CAN Bus ndi RS485, zomwe zimathandiza kuti pakhale kulumikizana bwino ndi makampani ambiri otsogola padziko lonse lapansi.
Ubwino waukulu wa mayankho a batri a YouthPOWER ndi awa:
- ♣Ukadaulo wa LiFePO4 wochita bwino kwambiri
- ♣Dongosolo Loyang'anira Mabatire anzeru (BMS)
Mapeto
Zonse CAN ndi RS485 zimagwira ntchito yofunika kwambiri m'makina amakono osungira mphamvu ndi mabatire a lithiamu.
CAN imapereka kulumikizana kwabwino kwambiri nthawi yeniyeni, kuzindikira matenda apamwamba, komanso kudalirika kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kuphatikiza batri ndi inverter mwaluso.
RS485 imapereka njira yolankhulirana patali, yosavuta, komanso yotsika mtengo, zomwe zimapangitsa kuti ikhale yankho lothandiza pa ntchito zambiri zamafakitale ndi dzuwa.
Mukasankha njira yosungira mphamvu ya batri, nthawi zonse onetsetsani kuti njira yolumikizirana ikugwirizana ndi inverter yanu komanso zofunikira pakuwunika. Kusankha batri yomwe imathandizira CAN ndi RS485 kumapereka kusinthasintha kwakukulu komanso kusagwirizana ndi mtsogolo.
Mafunso Ofunsidwa Kawirikawiri Zokhudza Kulankhulana kwa CAN Bus ndi RS485
Q1. Kodi CAN ndi RS485 zingagwiritsidwe ntchito nthawi imodzi mu dongosolo la batri lomwelo?
A1: Inde. Zambiri zamakonomakina a batri a lithiamuZimathandizira maulumikizidwe onse awiri nthawi imodzi. Izi zimathandiza ogwiritsa ntchito kulumikiza zida zosiyanasiyana zowunikira, ma inverter, kapena makina owongolera mphamvu kutengera zomwe polojekiti ikufuna.
Q2. Kodi njira yolumikizirana imakhudza momwe batire imagwirira ntchito pochaja?
A2: Mwanjira ina, inde. Kulankhulana kolondola kumalola inverter ndi makina oyang'anira batri kusinthana deta yogwirira ntchito bwino, zomwe zingathandize kulondola kwa chaji, ntchito zoteteza, komanso magwiridwe antchito onse a makina.
Q3. N’chifukwa chiyani opanga ma inverter amalangiza njira zinazake zolumikizirana?
A3: Wopanga inverter aliyense amapanga mapulogalamu okonzedwa bwino kuti agwirizane ndi njira zina zolumikizirana. Kugwiritsa ntchito njira yovomerezeka kumatsimikizira kuti ikugwirizana bwino, deta yolondola ya batri, komanso chitetezo chokwanira.
Q4. Kodi kulephera kwa kulumikizana kungawononge batire ya lithiamu?
A4: Kulephera kulankhulana nthawi zambiri sikuwononga batri yokha, koma kungachepetse mphamvu zowunikira, kuchepetsa magwiridwe antchito a makina, kapena kuyambitsa njira zotetezera zomwe zimakhudza ntchito zochaja ndi kutulutsa.
Q5. Ndingatsimikizire bwanji ngati batire ikugwirizana ndi inverter yanga?
A5: Nthawi zonse onaninso zomwe zili mu protocol yolumikizirana ya batri komanso mndandanda wazomwe zikugwirizana. Opanga monga YouthPOWER amapereka chidziwitso chogwirizana ndi mitundu yothandizira ya inverter ndi miyezo yolumikizirana musanayike.
