Kusintha kwa Ma EV Charging Protocols: Kusanthula Kofananira kwa OCPP 1.6 ndi OCPP 2.0

Kukula kofulumira kwaMagetsi Olipiritsa Magalimotozafunikira njira zoyankhulirana zokhazikika kuti zitsimikizire kugwirizana pakati pa EV Charging Stations and central management systems. Mwa ma protocol awa, OCPP (Open Charge Point Protocol) yatuluka ngati chizindikiro chapadziko lonse lapansi. Nkhaniyi ikuyang'ana kusiyana kwakukulu pakati pa OCPP 1.6 ndi OCPP 2.0, poyang'ana momwe amakhudzira teknoloji ya EV Charger, kuyendetsa bwino, ndikuphatikizana ndi miyezo yamakono monga CCS (Combined Charging System), GB / T, ndi DC kulipira mofulumira.

1. Ma Protocol Architecture and Communication Models

OCPP 1.6, yomwe idayambitsidwa mu 2017, imathandizira mitundu yonse ya SOAP (pa HTTP) ndi JSON (pa WebSocket), ndikupangitsa kulumikizana kosinthika pakati pawo.Ma Wallbox Chargerndi machitidwe apakati. Asynchronous messaging model amalolaMa EV Charging Stationskugwira ntchito monga kutsimikizira, kasamalidwe ka transaction, ndi zosintha za firmware.

OCPP 2.0.1(2020), kubwereza kwaposachedwa, kumatengera zomanga zolimba kwambiri zokhala ndi chitetezo chokhazikika. Imalamula HTTPS kuti ilumikizane ndi encrypted ndikuyambitsa masatifiketi a digito kuti atsimikizire chipangizocho, kuthana ndi zovuta m'mitundu yakale. Kusintha uku ndikofunikira kwambiriMalo opangira ma DC mwachangu, kumene kukhulupirika kwa deta ndi kuyang'anira nthawi yeniyeni ndizofunikira kwambiri.

2. Smart Charging and Energy Management

Chodziwika bwino cha OCPP 2.0 ndichotsogolaSmart Chargingkuthekera. Mosiyana ndi OCPP 1.6, yomwe imapereka kusanja koyenera, OCPP 2.0 imaphatikiza machitidwe owongolera mphamvu (EMS) ndikuthandizira ukadaulo wa Vehicle-to-Grid (V2G). Izi zimalolaEV Chargerkuti musinthe mitengo yolipiritsa potengera kuchuluka kwa gridi kapena kupezeka kwa mphamvu zongowonjezwwdwanso, kukulitsa kugawa mphamvu pa Ma EV Charging Stations.

Mwachitsanzo, Wallbox Charger yogwiritsa ntchito OCPP 2.0 imatha kuika patsogolo kulipiritsa pa nthawi imene simukugwira ntchito kwambiri kapena kuchepetsa mphamvu panthawi ya kusamvana kwa gridi, kupititsa patsogolo luso la nyumba ndi malonda.Kukhazikitsa kwa Electric Car Charging.

3. Chitetezo ndi Kutsata

Ngakhale OCPP 1.6 imadalira njira zovomerezeka zoyambira, OCPP 2.0 imayambitsa kubisa komaliza mpaka kumapeto ndi siginecha ya digito pazosintha za firmware, kuchepetsa ziwopsezo monga kulowa kosaloledwa kapena kusokoneza. Izi ndizofunikira kwambiriMasiteshoni a CCS ndi GB/T-compliant, yomwe imagwiritsa ntchito deta yachinsinsi ya ogwiritsa ntchito ndi zochitika za DC zamphamvu kwambiri.

4. Zithunzi Zowonjezereka za Data ndi Magwiridwe

OCPP 2.0imakulitsa mitundu ya data kuti ithandizire zovuta zolipiritsa. Ikubweretsa mitundu yatsopano ya mauthenga owunikira, kuyang'anira kusungitsa, komanso lipoti lanthawi yeniyeni, ndikupangitsa kuwongolera pang'onopang'ono.Ma EV Charging Stations. Mwachitsanzo, opareshoni amatha kuzindikira zolakwika pataliMagawo othamangitsa a DCkapena sinthani masinthidwe a Wallbox Charger popanda kulowererapo.

Mosiyana ndi izi, OCPP 1.6 ilibe thandizo lakwawo la ISO 15118 (Plug & Charge), malire omwe amayankhidwa mu OCPP 2.0 kudzera pakuphatikizana kosagwirizana ndi muyezo uwu. Kupita patsogolo kumeneku kumathandizira kutsimikizika kwa ogwiritsa ntchito pa CCS ndi masiteshoni a GB/T, ndikupangitsa kuti "plug-and-charge" azikumana nazo.

5. Kugwirizana ndi Kutengera Msika

OCPP 1.6 ikadali yovomerezeka kwambiri chifukwa cha kukhwima kwake komanso kugwirizana ndi machitidwe a cholowa, kuphatikizapo ma GB/T-based networks ku China. Komabe, kusagwirizana kwa OCPP 2.0 ndi mitundu yam'mbuyomu kumabweretsa zovuta pakukweza, ngakhale ali ndi mawonekedwe apamwamba monga kuthandizira V2G ndi kusanja kwapamwamba.

Mapeto

Kusintha kuchokera ku OCPP 1.6 kupita ku OCPP 2.0 kukuwonetsa kudumphadumpha kwakukulu muukadaulo wa Electric Car Charging, motsogozedwa ndi zofuna zachitetezo, kugwirizana, komanso kasamalidwe kanzeru ka mphamvu. Ngakhale OCPP 1.6 ikukwanira pamayendedwe oyambira a EV Charger, OCPP 2.0 ndiyofunikira pakutsimikizira zamtsogolo za EV Charging Station, makamaka zomwe zimathandizira.DC kuthamanga mwachangu, CCS, ndi V2G. Pamene makampaniwa akukula, kutengera OCPP 2.0 kudzakhala kofunikira kuti zigwirizane ndi miyezo yapadziko lonse lapansi komanso kupititsa patsogolo zokumana nazo za ogwiritsa ntchito pa Wallbox Charger ndi malo opangira anthu.
