Kusintha kwa Ma Protocol Ochaja a EV: Kusanthula Koyerekeza kwa OCPP 1.6 ndi OCPP 2.0

Kukula mwachangu kwaZomangamanga Zochajira Magalimoto Amagetsiyakhala ikufunika njira zolumikizirana zokhazikika kuti zitsimikizire kuti pali kugwirizana pakati pa Ma EV Charging Stations ndi machitidwe oyang'anira pakati. Pakati pa njirazi, OCPP (Open Charge Point Protocol) yakhala ngati muyezo wapadziko lonse lapansi. Nkhaniyi ikufotokoza kusiyana kwakukulu pakati pa OCPP 1.6 ndi OCPP 2.0, kuyang'ana kwambiri momwe zimakhudzira ukadaulo wa EV Charger, kugwiritsa ntchito bwino mphamvu ya chaji, komanso kuphatikizana ndi miyezo yamakono monga CCS (Combined Charging System), GB/T, ndi DC fast chaji.

1. Kapangidwe ka Protocol ndi Ma Model Olumikizirana

OCPP 1.6, yomwe idayambitsidwa mu 2017, imathandizira mitundu yonse ya SOAP (pa HTTP) ndi JSON (pa WebSocket), zomwe zimathandiza kulumikizana kosinthasintha pakati paMa Charger a Wallboxndi machitidwe apakati. Njira yake yotumizirana mauthenga yopanda mgwirizano imalolaMalo Ochapira Magalimoto a Moto (EV)kuti agwire ntchito monga kutsimikizira, kasamalidwe ka zochitika, ndi zosintha za firmware.

OCPP 2.0.1(2020), njira yatsopano yosinthira, ikugwiritsa ntchito kapangidwe kolimba kwambiri kokhala ndi chitetezo chowonjezereka. Imapereka HTTPS kuti ilumikizane mobisa ndipo imayambitsa satifiketi ya digito yotsimikizira chipangizo, kuthana ndi zovuta zomwe zili m'mitundu yakale. Kusintha kumeneku ndikofunikira kwambiri paMalo ochapira mwachangu a DC, komwe kukhulupirika kwa deta ndi kuwunika nthawi yeniyeni ndizofunikira kwambiri.

2. Kuchaja Mwanzeru ndi Kusamalira Mphamvu

Chinthu chodziwika bwino cha OCPP 2.0 ndi chakuti ndi yapamwamba kwambiri.Kuchaja Mwanzeruluso. Mosiyana ndi OCPP 1.6, yomwe imapereka kulinganiza koyambira kwa katundu, OCPP 2.0 imagwirizanitsa machitidwe owongolera mphamvu zamagetsi (EMS) ndikuthandizira ukadaulo wa Vehicle-to-Grid (V2G). Izi zimalolaMa EV Chargerskusintha mitengo yolipirira kutengera kufunikira kwa gridi kapena kupezeka kwa mphamvu zongowonjezwdwanso, kukonza kugawa kwa mphamvu m'malo onse ochapira magetsi a EV.

Mwachitsanzo, Wallbox Charger yogwiritsa ntchito OCPP 2.0 ingathandize kuyika patsogolo ntchito yochaja nthawi yomwe magetsi sakuchulukirachulukira kapena kuchepetsa mphamvu panthawi ya gridi yodzaza, zomwe zimapangitsa kuti magetsi azigwira bwino ntchito m'nyumba komanso m'mabizinesi.Makonzedwe a Kuchaja Magalimoto Amagetsi.

3. Chitetezo ndi Kutsatira Malamulo

Ngakhale kuti OCPP 1.6 imadalira njira zoyambira zotsimikizira, OCPP 2.0 imayambitsa njira zobisalira kuyambira kumapeto mpaka kumapeto ndi ma siginecha a digito kuti zisinthidwe ndi firmware, zomwe zimachepetsa zoopsa monga mwayi wosaloledwa kapena kusokoneza. Izi ndizofunikira kwambiri kwaMasiteshoni otsatira malamulo a CCS ndi GB/T, zomwe zimayang'anira deta yachinsinsi ya ogwiritsa ntchito komanso zochitika za DC zamphamvu kwambiri.

4. Ma Model Owonjezera a Deta ndi Magwiridwe Abwino

OCPP 2.0imakulitsa mitundu ya deta kuti ithandizire zochitika zovuta zolipiritsa. Imayambitsa mitundu yatsopano ya mauthenga kuti ipeze matenda, kasamalidwe ka malo osungitsa malo, komanso malipoti a momwe zinthu zilili nthawi yeniyeni, zomwe zimathandiza kuti pakhale kuwongolera kwakukulu paMalo Ochapira Magalimoto a Moto (EV)Mwachitsanzo, ogwira ntchito amatha kuzindikira zolakwika pataliMagawo ochapira mwachangu a DCkapena sinthani makonzedwe a Wallbox Chargers popanda kulowererapo pamalopo.

Mosiyana ndi zimenezi, OCPP 1.6 ilibe chithandizo chapadera cha ISO 15118 (Plug & Charge), chomwe chimalepheretsedwa mu OCPP 2.0 kudzera mu kuphatikizana bwino ndi muyezo uwu. Kupita patsogolo kumeneku kumapangitsa kuti kutsimikizira kwa ogwiritsa ntchito kukhale kosavuta pa siteshoni za CCS ndi GB/T, zomwe zimathandiza kuti zinthu zizigwiritsidwa ntchito "plug-and-charge".

5. Kugwirizana ndi Kugwiritsidwa Ntchito Msika

OCPP 1.6 ikupitilirabe kugwiritsidwa ntchito kwambiri chifukwa cha kukhwima kwake komanso kugwirizana kwake ndi machitidwe akale, kuphatikizapo ma netiweki okhala ndi GB/T ku China. Komabe, kusagwirizana kwa OCPP 2.0 ndi mitundu yakale kumabweretsa zovuta pakukweza, ngakhale kuti ili ndi mawonekedwe abwino kwambiri monga kuthandizira V2G ndi kulinganiza bwino katundu.

Mapeto

Kusintha kuchokera ku OCPP 1.6 kupita ku OCPP 2.0 kukuwonetsa kusintha kwakukulu muukadaulo wa Electric Car Charging, chifukwa cha kufunika kwa chitetezo, mgwirizano, ndi kasamalidwe ka mphamvu mwanzeru. Ngakhale OCPP 1.6 ndi yokwanira pa ntchito zoyambira za EV Charger, OCPP 2.0 ndi yofunika kwambiri pa malo ochapira a EV omwe adzatetezedwe mtsogolo, makamaka omwe amathandiziraDC yochaja mwachangu, CCS, ndi V2G. Pamene makampani akusintha, kugwiritsa ntchito OCPP 2.0 kudzakhala kofunikira kwambiri kuti zigwirizane ndi miyezo yapadziko lonse lapansi ndikuwonjezera zomwe ogwiritsa ntchito amagwiritsa ntchito ku Wallbox Chargers ndi malo ochapira anthu onse.
