Ibikorwa remezo bya EV bya Engineering Resilient: Isesengura ryimbitse rya tekiniki ku micungire y'ubushyuhe, fiziki y'ibihombo bya elegitoroniki, ISO 15118 Communication Stability, n'ingamba zo gusuzuma ibikoresho bikoresha amashanyarazi menshi mu kirere.

1. Intangiriro: Iterambere ry'Ubwizerwe bwa EVSE n'Ingamba zo Gukoresha Uptime

Impinduka ku isi yose igana ku buryo bwo kugenda kw'amashanyarazi ntabwo ikiri ikintu cyo hanze ahubwo ni inkingi nyamukuru ya politiki y'inganda n'ingamba zo kubungabunga ibidukikije. Uko ikoreshwa ry'ibinyabiziga by'amashanyarazi (EV) rigenda ryihuta, ibikorwa remezo by'ibikoresho by'amashanyarazi (EVSE) bihura n'ibibazo bitari byarigeze bibaho. Bitandukanye n'ibikoresho by'ikoranabuhanga bikoreshwa n'abaguzi cyangwa ndetse n'ibinyabiziga bitwara moteri mu nganda, ibyuma bitanga amashanyarazi—cyane cyane DC Fast Chargers (DCFC) na Ultra-Fast Chargers (UFC)—bikorera aho imbaraga nyinshi zihurira, imiterere y'ibidukikije ihinduka, hamwe n'amabwiriza akomeye yo gusabana mu buryo bw'ikoranabuhanga.

Ikintu gihora kibabaza abakoresha ndetse n'abakoresha ni "guhagarara" cyangwa "gushyuha cyane". Iyo charger ihagaritse ikoreshwa ry'amashanyarazi mbere y'igihe cyangwa igahagarika umuriro bitewe n'ubushyuhe bukabije, bigaragaza ko sisitemu yananiwe guhuza. Iyi nkuru itanga isesengura ryimbitse ry'ikoranabuhanga ku mpamvu nyamukuru z'izi mpanuka, kuva ku buhanga bw'ibanze bw'ibura ry'amashanyarazi ya semiconductor kugeza ku buryo bugoye bwo guhagarara kw'itumanaho rya ISO 15118 na RCD tripping dynamics. Dusobanukiwe ubu buryo bwo gutsindwa binyuze mu ikoranabuhanga ry'amashanyarazi n'ubushyuhe, dushobora gukora imiyoboro yo gusharija ihamye, ifite ubwenge, kandi ikora neza.

2. Fiziki y'ibura ry'ingufu mu guhindura ingufu zigenda ziyongera cyane

Ishingiro rya buri shajara ya EV ni module yo guhindura amashanyarazi, ihindura grid AC muri DC igenzurwa isabwa na bateri y'imodoka. Ikibazo "cyo gushyuha cyane" ni ukudashobora gucunga ubushyuhe buterwa n'ibura ry'amashanyarazi muri iki gikorwa cyo guhindura amashanyarazi. Kugira ngo tubikemure, tugomba kubanza gupima aho izi ngufu zijya.

2.1. Ibihombo mu muyoboro w'amashanyarazi

Igihombo cyo mu muyoboro giterwa n’uko ibikoresho bya semiconductor (IGBTs cyangwa MOSFETs) n’ibice bidakora neza iyo biri mu mimerere ya "on". Muri Silicon Carbide (SiC) MOSFETs, zigenda zisimbura Silicon IGBTs gakondo, igihombo cyo mu muyoboro giterwa no kudakora neza kw’ingufu ($R_{DS(on)}$). $$P_{cond} = I_{RMS}^2 \times R_{DS(on)}(T_j)$$ By’ingenzi, $R_{DS(on)}$ iterwa n’ubushyuhe. Uko ubushyuhe bw’aho yerekeza buzamuka ($T_j$) ni ko ubwiyongere bw’ubushyuhe bwiyongera, bigatuma habaho uburyo bwo gusubiza ibintu neza bushobora gutuma ubushyuhe bugenda nabi mu gihe budacunzwe neza.

2.2. Guhindura Igihombo

Gutakaza ingufu bibaho mu gihe cy'impinduka hagati ya ON na OFF. Muri izi ntera za nanosecond, ingufu z'amashanyarazi n'amashanyarazi byombi ntibiba zeru kuri igikoresho, bigatuma ingufu zikwirakwira ($E_{on}$ na $E_{off}$). $$P_{sw} = f_{sw} \times (E_{on} + E_{off})$$ Muri DCFC zigezweho, abashushanya bashyira imbaraga mu guhinduranya ingufu ($f_{sw}$) kugira ngo bagabanye ingano y'ibice bya rukuruzi (inductors na transformers). Ariko, imbaraga z'amashanyarazi zongera umutwaro w'ubushyuhe mu buryo butaziguye, bigasaba ko habaho uburyo bwo kunoza imikorere y'umuyoboro w'amashanyarazi mu rwego rwo hejuru kugira ngo bigabanye imiterere y'amashanyarazi n'amashanyarazi.

2.3. Igihombo cya rukuruzi n'ibicurane

Uretse semiconductors, transformer ifite frequency yagutse na inductors bigira uruhare runini mu ngengo y'imari y'ubushyuhe. Igihombo cy'ibanze (hysteresis na eddy currents) n'igihombo cy'umuringa (ingaruka z'uruhu n'ingaruka zo kuba hafi) mu mizunguruko bishobora gutuma habaho igihombo cya module yose kigera kuri 20%. Uko chargers ziyongera zikagera kuri 350kW no kurenzaho, gucunga ibi bihombo "bidakora" biba ingenzi cyane nk'uko semiconductors ubwazo zibikora.

3. Ubudahangarwa bw'ubushyuhe n'ihindagurika ry'ubushyuhe: Imibare yo gushyuha cyane

"Gushyuha cyane" ni ijambo risobanurwa n'ubushyuhe ntarengwa bwo gukora bw'igice cy'ingenzi cyane—akenshi ni aho amashanyarazi ahurira cyangwa umuyoboro wa DC output cable connector.

Ubudahangarwa bw'ubushyuhe bwose ($\theta_{JA}$) kuva aho buhurira kugera aho buherereye ni: $$\theta_{JA} = \theta_{JC} + \theta_{CH} + \theta_{HA}$$ Aho:

• $\theta_{JC}$ ni ukurwanya guhuza ibikoresho (imbere mu gikoresho).
• $\theta_{CH}$ ni ubudahangarwa bw'ubushyuhe (bugengwa na Thermal Interface Materials – TIM).
• $\theta_{HA}$ ni uburyo bwo kurwanya ubushyuhe cyangwa ikirere (bugengwa n'uburyo bwo gukonjesha).

3.2. Ahantu hakunze kugaragara cyane ugereranyije n'ubushyuhe bwinshi

Imashini nyinshi zitanga umuriro zirahagarara bitewe n'aho zihurira n'aho sensor za sisitemu zishobora kubura. Urugero, bolt ifunguye gato kuri DC busbar ishobora gutuma habaho ubushobozi bwo guhangana n'amashanyarazi mu rugero rwa milliohm. Kuri 500A, ubushobozi bwo guhangana na 1m$\Omega$ butanga ubushyuhe bwa 250W mu rugero ruto, bigatuma ubushyuhe bugabanuka vuba kandi bigatera kuzimya ubushyuhe mbere yuko sisitemu ikonjesha izamuka ry'ubushyuhe bw'umwuka.

3.3. Uburyo bwo gushyushya hakoreshejwe ubushyuhe

Abagenzuzi ba EVSE ba none bashyiraho imipaka "yoroshye". Aho kuzimya cyane, sisitemu igabanya umuvuduko ntarengwa wemewe ($I_{max}$) uko ubushyuhe bwegereje umupaka runaka. Iyo umuvuduko w'ubushyuhe uzamutse ($dT/dt$) urenze umupaka runaka, sisitemu iteganya ko hazabaho ikibazo kandi igahagarika gahunda kugira ngo hirindwe kwangirika kw'ibikoresho. Gusobanukirwa iyi logique ni ingenzi mu gusuzuma impamvu charger ishobora "guhagarara" bisa nkaho ari ku munsi w'ubushyuhe.

4. Imiterere ihanitse yo gukonjesha: Gukonjesha amazi ugereranije n'imiyoboro y'umwuka yigenga
