48V vs 36V Gorofu Ngoro Battery: Ndeipi Imwe YeFleet Yako
Isu tinobvunzwa mubvunzo uyu nguva dzose. Uye nokutendeseka, ye90% yemabasa ekutengesa achibvunza nhasi, mhinduro ndeye 48V. Kwete nokuti "zviri nani" mune imwe pfungwa isinganzwisisiki, asi nokuti maitiro e36V haana kugadzirwa neOEMs makuru kubvira 2008. Kana uri kutenga zvitsva, uri kutenga 48V. Sarudzo chaiyo ndeyezvinoitika kune yako iripo 36V zvikepe, uye kana lithium shanduko ine musoro wemari pabasa rako.
Zvakadaro, ndakaona zvikwata zvekutenga zvinhu zvichiparadza mari yakakomba pamativi ese equation iyi. Kunyanya kushandisa mari pane zvisina basa kusimudzira masimba. Kushandisa mari pasi pezvivakwa uyezve kubata nekutadza kwechaja mwedzi mitanhatu gare gare. Kuedza kushandura magetsi kunodhura kudarika ngoro dzekutsiva. Izvo zvinokanganisa zvinofanotaurwa kana iwe waona zvakakwana kwavari.
Iyo Tekinoroji Gap muPlain Terms
Iyo 48V sisitimu inodhirowa zvishoma ikozvino kuendesa simba rimwe chete. Pa2,400 watts inobuda, ndiwo makumi mashanu amps maringe ne66.7 amps ye36V. Iyo yakaderedzwa ikozvino inoreva kushoma kupisa mune yako wiring, controller, uye mota. Isu takaona controller heatsinks ichimhanya 15-20 dhigirii inotonhorera pane 48V setups pasi pekuyedzwa kwakafanana kwemutoro. Kupisa ndiko kunouraya zvemagetsi nekufamba kwenguva, saka izvi zvine basa rehupenyu hurefu hwezvikepe.
Mumwe mutsauko wekuita ndeye torque. Kumhanyisa mota kune yakakwira voltage kunowedzera torque inobuda neinosvika 25-33%. Pamafurati eFlorida makosi, hauone. Panzvimbo ine makomo muCarolinas kana Arizona renje zvivakwa zvine kukwirira shanduko, vashanyi vako vachazviita.

Makore matatu apfuura, tinenge tichiri kufungidzira 36V lithium kune mamwe maapplication. Zvikepe zvidiki zvenharaunda, nzvimbo yakati sandara, zvipingaidzo zvebhajeti. Kuchengetwa kwemutengo kwaireva uye musiyano wekuita waigamuchirwa.
Kuverenga ikoko kwachinja. Mutengo unosiyaniswa pakati pe36V ne48V lithium packs waita diki kusvika pamadhora mazana mana-600 pangoro. Zvichakadaro, musika wekutengesa we36V ngoro dziri kuramba dzichidzikira sezvo vatengi vachitarisira nyaya dzekuwanikwa kwezvikamu. Kana mutengi akatikumbira kuti titarise 36V system nhasi, tinosundira kumashure. Kwete nekuti 36V haishande, asi nekuti maonero emakore mashanu anofarira kumira pa48V.
Chinosara ndeche mapurojekiti ekudzorera pazvikepe zve36V zviripo ane 5+ makore ehupenyu hwemuchina asara. Kushandura idzo ngoro ku48V hazviwanzo kuita zvine musoro (zvimwe pane izvo pazasi). Kudonhedza mu36V lithium pack uye kuwedzera hupenyu hwesevhisi neimwe gumi inogona kuve kufona chaiko.
