E whakahīhī ana a Beihai Powder, he kaiārahi i roto i ngā otinga utu EV auaha, ki te whakauru i te "20kw-40kw Rīhi DC Kiato"–he otinga whakarerekētanga kēmu i hangaia hei whakakī i te āputa i waenga i te utunga AC puhoi me tete utu tere DC mana teiteiI hangaia mō te ngāwari, te utu tika, me te tere, ka whakamanahia e tēnei rihi hiko ngā pakihi me ngā hapori ki te awhi i te nekenekehanga pumau me te kore e whakararu i te whai huatanga.
Ngā rihi DC iti(20kW-40kW) he painga nui atu i ngā hiko hiko teitei tuku ihoNgā rihi DC(120kW+). He iti ake te utu, ā, he iti ake ngā whakapaunga tāutanga nā te iti o ngā whakapainga whatunga hiko. Nā te iti o te whakamahinga hiko ka whakaitihia ngā utu whakahaere, ka tere ake te ROI (6-18 marama). He nui ake te utu mō ngā rihi hiko-teitei, ā, he nui ngā hanganga e hiahiatia ana, ā, he roa ake ngā wā ROI (2-5 tau).
He tino ngāwari te urutau o ngā rihi DC iti, e mahi ana i runga i ngā ara iahiko paerewa 220V-380V, ā, e uru ana ki ngā wāhi kiato (0.5-1㎡). Ka whakatūria i roto i te 1-3 rā, he mea tino pai mō ngā toa hokohoko, ngā tari, me ngā hōtēra. Me whakamahi ngā ara iahiko ngaohiko teitei mō ngā rihi hiko teitei, ā, e 1-3 marama te roa o te tāutanga, ka herea noa ki ngā huarahi tere me ngā teihana motuhake.
Me ngā tere utu o te 20-50kW (100-250 km/h), he pai ngā rihi DC iti mō ngā EV iti ki te rahi (≤80kWh) me te whakamahi i ngā pūnaha whakamatao māmā, kia pono ai te mahi me te roa o te ora mō ngā tau 8-10. Mana-TeiteiTeihana utu DC(120-350kW, 500-1000 km/h) e whakatutuki ana i ngā EV nunui (≥100kWh) engari ka whakawhirinaki ki te whakamatao wai matatini, ka piki ake te tere o te rahunga me te whakaiti i te roa o te ora ki te 5-8 tau.
He tino pai ngā rihi hiko DC iti i roto i ngā taiao arumoni me ngā taiao hapori, e tuku ana i te utu utu iti mō ngā waka (hei tauira, ngā tekesi, ngā ratonga kawe) me ngā wāhi tūmatanui he iti te kaha o te whatunga hiko. Ka whakaratohia he wheako ngāwari ki te whakamahi me ngā wā utu 1-3-hāora, he iti ngā utu, me te pono teitei. Ahakoa he tere ake ngā rihi hiko teitei, he pai ake mō ngā whakakī ohorere engari he nui ake ngā utu.
Mō te taiao, he rite ngā rihi hiko DC iti ki ngā kaupapa here pūngao o te tāone, he iti te parahanga o te haurore, ā, he whakauru atu ki ngā pūnaha pūngao rā/rokiroki. He maha ngā wā ka hiahiatia he whakaaetanga ahumahi mō ngā rihi hiko mana nui, ā, ka taea te whakararu i ngā whatunga ā-rohe.
Hei whakarāpopototanga, he iti te utu, he ngāwari, he pumau hoki ngā rihi DC iti, ā, he pai mō te whakamahinga o te tāone me te arumoni, ko te hiko DC kaha teitei ia he pai mō te whakamahi i ngā tāone nui me ngā tāone iti.ngā rihi waka hikohe mea nui tonu mō ngā haerenga nui me ngā haerenga tawhiti.
