Kuchaja kwa AC ndi DC: Kodi Kusiyana Kwake N'kutani?

Magetsi ndiye maziko a magalimoto onse amagetsi. Komabe, si magetsi onse omwe ali ndi khalidwe lofanana. Pali mitundu iwiri ikuluikulu ya magetsi: AC (alternating current) ndi DC (direct current). Mu positi iyi ya blog, tifufuza kusiyana pakati pa AC ndi DC charging ndi momwe zimakhudzira njira yochajira magalimoto amagetsi. Koma tisanafufuze zambiri, tiyeni tifotokoze kaye. Alternating current ndi yomwe imachokera ku grid yamagetsi (monga, malo otulutsira magetsi m'nyumba mwanu). Direct current ndi mphamvu yosungidwa mu batire yagalimoto yanu yamagetsi.

Kuchaja kwa EV: kusiyana pakati pa AC ndi DC

 Mphamvu ya DC

 Mphamvu ya DC (direct current) ndi mtundu wa mphamvu yamagetsi yomwe imayenda mbali imodzi. Mosiyana ndi mphamvu ya AC, yomwe imasintha njira nthawi ndi nthawi, mphamvu ya DC imayenda mbali imodzi. Nthawi zambiri imagwiritsidwa ntchito m'zida zomwe zimafuna mphamvu yokhazikika komanso yokhazikika, monga makompyuta, ma TV, ndi mafoni a m'manja. Mphamvu ya DC imapangidwa ndi zida monga mabatire a EV ndi ma solar panels, zomwe zimapangitsa kuti mphamvu yamagetsi iyende bwino. Mosiyana ndi mphamvu ya AC, yomwe ingasinthidwe mosavuta kukhala ma voltage osiyanasiyana pogwiritsa ntchito ma transformer, mphamvu ya DC imafuna njira yovuta kwambiri yosinthira kuti isinthe magetsi ake.

Mphamvu ya AC

Mphamvu ya AC (alternating current) ndi mtundu wa mphamvu yamagetsi yomwe imasintha njira nthawi ndi nthawi. Njira ya AC voltage ndi current imasintha nthawi ndi nthawi, nthawi zambiri pa 50 kapena 60 Hz. Njira ya magetsi ndi volteji zimabwerera m'mbuyo nthawi ndi nthawi, ndichifukwa chake zimatchedwa alternating current. Magetsi a AC amadutsa m'mizere yamagetsi ndikulowa m'nyumba mwanu, komwe amapezeka kudzera m'malo otulutsira magetsi.

Zabwino ndi zoyipa za AC ndi DC charging

 Ubwino wa kuyatsa AC:

1. Kutha Kufikira. Kuchaja kwa AC kumakhala kosavuta kwa anthu ambiri chifukwa kungachitike pogwiritsa ntchito soketi yamagetsi yokhazikika. Izi zikutanthauza kuti oyendetsa ma EV amatha kutchaja kunyumba, kuntchito, kapena m'malo opezeka anthu ambiri popanda zida zapadera kapena zomangamanga.
2. Chitetezo. Kuchaja kwa AC nthawi zambiri kumaonedwa kuti ndikotetezeka kuposa njira zina zochajira chifukwa kumapereka mphamvu mu mawonekedwe a sine waveform, omwe sangayambitse kugwedezeka kwamagetsi poyerekeza ndi ma waveform ena.

1. Kutsika mtengo. Kuchaja kwa AC ndikotsika mtengo kuposa njira zina zochajira chifukwa sikufuna zida zapadera kapena zomangamanga. Izi zimapangitsa kuti ikhale njira yotsika mtengo kwambiri kwa anthu ambiri.

Zoyipa zochapira AC:

1. Nthawi yochaja pang'onopang'ono.Ma AC charger ali ndi mphamvu yochepa yochaja ndipo ndi ochedwa kuposa ma DC station, zomwe zingakhale zovuta kwa ma EV omwe amafunika kuchaja mwachangu pamsewu, monga omwe amagwiritsidwa ntchito paulendo wautali. Nthawi yochaja kuti AC charger iyambe imatha kuyambira maola angapo mpaka masiku, kutengera mphamvu ya batri.

1. Kugwiritsa ntchito bwino mphamvu.Ma AC charger sagwiritsa ntchito mphamvu zambiri monga malo ochajira mofulumira kwambiri chifukwa amafunika transformer kuti asinthe magetsi. Njira yosinthirayi imabweretsa kutayika kwa mphamvu, zomwe zingakhale zovuta kwa iwo omwe akuda nkhawa ndi kugwiritsa ntchito mphamvu moyenera.

Kodi AC kapena DC ndi yabwino kwambiri pochaja?

Izi zidzadalira zosowa zanu zolipirira. Ngati mumayendetsa mtunda waufupi tsiku lililonse, ndiye kuti kuwonjezera nthawi zonse pogwiritsa ntchito chochapira cha AC kuyenera kukhala kokwanira. Koma ngati nthawi zonse mumakhala panjira ndipo mukuyendetsa mtunda wautali, kutchaja kwa DC ndiye njira yabwino, chifukwa mutha kuchaja EV yanu yonse pasanathe ola limodzi. Dziwani kuti kuchaja mwachangu pafupipafupi kungayambitse kuwonongeka kwa batri chifukwa mphamvu yayikulu imapangitsa kutentha kwambiri.

Kodi ma EV amagwira ntchito pa AC kapena DC?

Magalimoto amagetsi amagwiritsa ntchito mphamvu yamagetsi mwachindunji. Batire yamagetsi yamagetsi imasunga mphamvu zamagetsi mu mtundu wa DC, ndipo mota yamagetsi yomwe imayendetsa galimotoyo imagwiritsanso ntchito mphamvu ya DC. Kuti mupeze zosowa zanu zochajira magetsi, onani zosonkhanitsa za Lectron za ma charger amagetsi, ma adapter, ndi zina zambiri za Tesla ndi J1772 EV.
