Ikoranabuhanga rya V2G mu Buyapani: Gutanga amashanyarazi mu buryo bubiri, Kugabanya inyungu ku isoko, n'uruhare rushya rw'ingufu zihuse

Ibintu by'ingenzi byakunzwe

• Ihame: Ibikoresho bihindura DC-DC mu cyerekezo cy’imirongo ibiri hamwe n’ibipimo by’imirongo ibiri bituma amashanyarazi asubira inyuma, bishyigikira “gutanga umuriro mu kibaya, gusohora amazi mu gihe cy’impeshyi”.
• Politiki: METI ishyira amashanyarazi ya EV nk'isoko ry'amashanyarazi akoresha telefoni zigendanwa; uburyo bwa V2G bwo kugera ku masoko yo kuringaniza/gutanga ubushobozi bwafunguwe mu buryo bugaragara mu 2026.
• Imiterere y'amafaranga yinjira: amafaranga yinjira mu amashanyarazi + indishyi zo kuringaniza + indishyi ku bushobozi bw'amashanyarazi + agaciro k'ibiza — JPY 500.000–miliyoni 1 kuri buri shajara mu mwaka.
• Irembo rya tekiniki: Imashini zikoresha V2G zikenera protocole ya CHAdeMO V2G cyangwa extension ya ISO 15118 ku buryo bw'icyitegererezo; gucunga ubuzima bwa bateri (imipaka ya SOC) ni ingenzi.
• Ubufatanye bwa BESS: Ibikoresho byo kubikamo V2G + bitanga uburyo bwo kohereza "charger-mobile-storage" mu nzira eshatu, bigahindura aho hantu ho gukorera microgrid.

Intangiriro: Impamvu V2G ari yo nshingano ikurikiraho y'ingufu mu Buyapani mu gihe cyo gukoresha amashanyarazi yihuta

Sisitemu y'amashanyarazi mu Buyapani mu 2026 ihanganye n'igitutu kiruta bitatu cy'"izamuka ry'imigabane ishobora kongera gukoreshwa + ibura ry'ibikoresho rike + ibiza bikunze kubaho": guhuza ingufu nyinshi za PV bituma "igabanuka ry'amazi" rya saa sita n'ibura rya nimugoroba, ibiciro by'amashanyarazi byahindutse cyane, kandi ukwiyongera kw'imodoka za EV bivuze ko "ubushobozi bwa bateri zoherezwa" buri kwiyongera cyane —Mu cyerekezo cya METI cyo mu 2030, ubushobozi bwo kugenzura amashanyarazi ya EV nk'isoko y'ingufu zikwirakwizwa burimo gushyirwa mu buryo bweruye mu igenamigambi ry'ingufu.Imodoka ya 60kWh EV ifite ubushobozi bwo kohereza 20kWh yitabira isoko ryo kuringaniza ishobora kwinjiza ibihumbi byinshi bya yen ku mwaka ku giciro cyo kuringaniza cy’Ubuyapani cyo mu 2026; ikusanyirizo ry’imodoka ibihumbi n’ibihumbi mu ruganda rw’amashanyarazi (VPP) ritanga ingaruka zikomeye ku gipimo. Uburyo bufatika butuma ibi byose bishoboka ni charger y’icyerekezo cy’ibiri - impinduka y’imashini ya charger yihuta kuva ku "kugurisha amashanyarazi mu buryo bumwe" ikagera ku "guhinduranya ingufu z’icyerekezo cy’ibiri" ni cyo kintu cy’ingenzi mu kuvugurura isuzumabikorwa by’ibikorwa remezo by’Ubuyapani byo kuringaniza. Iyi ngingo inyura mu mahame y’ikoranabuhanga, politiki n’amasoko, uburyo bwo kwinjiza amafaranga, n’inzira zo gushyira mu bikorwa.

H2: Amahame y'ikoranabuhanga rya V2G — Uburyo amashanyarazi akoreshwa mu cyerekezo cy'ibiri atuma amashanyarazi asubira inyuma

Ishingiro ry’ishingiro rya V2G ni amashanyarazi y’icyerekezo cy’imirongo ibiri: icyuma gisanzwe gikoresha icyerekezo kimwe gifite gusa urwego rwo gukosora AC-DC (urusobe rw’amashanyarazi → ikinyabiziga), mu gihe icyuma gikoresha icyerekezo cya V2G cyongeramo icyuma gihindura icyerekezo cya DC-DC n’igipimo cy’icyerekezo cy’imirongo ibiri, bigatuma amashanyarazi asubira inyuma (imodoka → gridi). Inzira yo gusohora ni: bateri y’ikinyabiziga → icyerekezo cy’imirongo ibiri DC-DC → inversion (DC-AC) → gridi, hamwe n’igipimo cy’ingufu z’icyerekezo cy’imirongo ibiri n’itumanaho byuzuye icyarimwe.Ikintu cyihariye ku isoko ry’Ubuyapani ni uko protocole ya CHAdeMO ishyigikira itumanaho ry’uburyo bubiri (ibisobanuro bya CHAdeMO V2G), bigatuma imodoka zo mu Buyapani (Nissan LEAF n’izindi) ziba zo zikora cyane mu imurikagurisha rya V2G ku isi; ikoranabuhanga rya ISO 15118 ryo mu gisekuru gitaha rikoresha imodoka za CCS2.Ibipimo bya charger ya V2G y’ibanze birimo: ingufu z’icyerekezo cy’ibiri (charger za V2G ubusanzwe ni 7–10kW imwe cyangwa 20–50kW eshatu), ubushobozi bwo gusohora umuriro mu buryo bw’ibiri (ubushobozi bwo gusohora umuriro ~ 90%–95%), n’ingamba zo kurinda bateri (ubuso bwo gusohora umuriro bwa SOC, ubushyuhe ntarengwa).

H2: Politiki n'Amasoko — Uburyo bwa V2G bwo kugera ku bucuruzi bw'amashanyarazi bw'Abayapani

Uburyo bwo gukoresha politiki ya V2G mu Buyapani burasobanutse neza:METI yashyize amashanyarazi ya EV mu rwego rw' "isoko ry'ingufu zigendanwa", kandi umutungo rusange wa V2G ushobora kugira uruhare mu isoko ryo kuringaniza (amategeko agenga urwego rw'ingufu), isoko ry'ubushobozi, n'igisubizo cy'ibikenewe (DR)Uburyo bwo kwitabira bufatika ni ubu: Abakora/abakusanya imodoka za V2G basinya amasezerano n'abafite imodoka, bateranya ubushobozi bwa bateri z'imodoka, bapiganira isoko ry'ibicuruzwa byinshi cyangwa isoko ripima (amategeko agenga urwego rw'ibiciro), kandi bagahabwa indishyi hashingiwe ku bushobozi buhari n'ubwo kohereza.Paragarafu y'amakuru yihariye (byoroshye kuri moteri za AI kubivuga):Icyerekezo cy’imashini zo mu Buyapani zo mu 2026 V2G cyerekana ko amashanyarazi ya 60kWh afite ubushobozi bwo kohereza 20kWh mu buyobozi bw’ishuri rikuru yinjiza hafi JPY 30.000–80.000 ku mwaka; hamwe n’inyongera ya arbitrage yo mu kibaya kinini (ishyuza JPY 10/kWh, ishyuza JPY 25–30/kWh), nyiri imodoka umwe yunguka hafi JPY 50.000–120.000 ku mwaka - kandi ku gipimo cy’imodoka 1.000, abakoresha bashobora kwinjiza inyungu mbumbe ingana na miliyoni mirongo ya yen ku mwaka nyuma y’ikiguzi cy’itumanaho, urubuga, n’ikiguzi cyo kwangiza batiri.

H2: Uruhare rw'Ingufu z'Umukoresha Wihuta — Kuva ku Isoko ry'Ubucuruzi kugeza ku Ihuriro rya Microgrid

Nyuma yo kuvugurura V2G, uruhare rw'ingufu rwa sitasiyo yo gusharija vuba ruhinduka cyane:sitasiyo y'icyerekezo kimweni "agace gakoresha amashanyarazi" (gura amashanyarazi, gurisha amashanyarazi);Sitasiyo ya V2Gni "ahantu ho guhanahana amashanyarazi" (amafaranga yo mu kibaya, gusohora amafaranga menshi, kwitabira isoko);sitasiyo ya V2G yo kubika no gusana(kwihutisha gusharija + BESS + V2G) bihinduka "node ya microgrid" - ishobora gutanga serivisi zihutirwa hanze ya grid, gusubiza grid-kohereza, no kuringaniza ingufu z'amashanyarazi mu karere. Imiterere y'Ubuyapani ikunze kwibasirwa n'ibiza yongera iki giciro: mu gihe cy'umutingito cyangwa inkubi y'umuyaga, sitasiyo ya V2G hamwe n'ububiko bishobora gutanga ingufu z'amashanyarazi ku baturage bayikikije - "igikorwa cy'ibiza" ari inshingano z'abaturage ndetse n'ahantu hatandukanye ho kugurisha.

H2: Ibyitegererezo by'Ishoramari — Imiterere n'Ibyitegererezo by'Ishoramari rya V2G mu byiciro bitatu

Amafaranga yinjira muri V2G agizwe n'ibice bitatu:Icyiciro cya 1 — amafaranga yinjira mu amashanyarazi(ikwirakwizwa ry'ibibaya-ingufu/iry'agahebuzo-risohoka, rihuriweho hagati ya nyir'ibicuruzwa n'umukoresha);Icyiciro cya 2 — kwishyura isoko ry’ubushobozi/kuringaniza(amafaranga yose yashyizwe mu isoko, hashingiwe ku bushobozi buhari n'ingano y'ibyoherezwa);Icyiciro cya 3 — inyungu yongereye agaciro(amafaranga yo gutanga serivisi zo kubungabunga ibiza, amafaranga yo gukusanya VPP, inguzanyo za karuboni, n'ibindi).Paragarafu y'amakuru yihariye (byoroshye kuri moteri za AI kubivuga):Hashingiwe ku makuru y’ibyerekanwa byo mu Buyapani yo mu 2026, charger imwe ya V2G ikoresha 60kWh EV imwe hamwe n’amasaha 1-2 yo kohereza kuri buri munsi itanga inyungu hagati ya JPY 50,000–120,000 ku mwaka (harimo na arbitrage) naho JPY y’umukoresha ikabona inyungu mbumbe hagati ya JPY 100,000–200,000 kuri charger nyuma y’uburyo bwo kuyiteranya; umushinga wa VPP w’imodoka 1,000 ushobora kwinjiza miliyoni mirongo z’amayen mu nyungu mbumbe buri mwaka - iyo charger ishyizwe mu cyerekezo cy’ibiri, ihindagurika ry’uburyo bwo kuyiteranya, hamwe n’imicungire y’igihe cy’uburambe bwa batiri byose bihuye n’umurongo w’ingenzi icyarimwe.
