Ka hare ho koloi e entsoe ka likarolo tse ngata, haholo-holo ka mor'a ho kenngoa ha motlakase.Morero oa sethala sa voltage ke ho tsamaisana le litlhoko tsa matla tsa likarolo tse fapaneng.Likarolo tse ling li hloka motlakase o batlang o le tlase, joalo ka 'mele oa elektronike, lisebelisoa tsa boithabiso, lilaoli, joalo-joalo (ka kakaretso 12V voltage platform power supply),' me tse ling li hlokamatla a phahameng, joalo ka lits'ebetso tsa betri, litsamaiso tse phahameng tsa motlakase, lits'ebetso tsa ho tjhaja, joalo-joalo (400V / 800V), kahoo ho na le sethala se phahameng sa motlakase le sethala sa motlakase o tlase.
Ebe u hlakisa kamano pakeng tsa 800V le tefiso e potlakileng haholo: Hona joale koloi e hloekileng ea mopalami ea motlakase ka kakaretso e ka ba sistimi ea betri ea 400V, enjene e tsamaellanang, lisebelisoa, thapo e phahameng ea voltage le eona ke boemo bo ts'oanang ba voltage, haeba motlakase oa sistimi e eketseha, ho bolela hore tlas'a tlhokahalo e tšoanang ea matla, hona joale e ka fokotsoa ka halofo, tahlehelo ea tsamaiso eohle e fetoha e nyenyane, mocheso o fokotsehile, empa hape le boima bo eketsehileng, ts'ebetso ea koloi e thusa haholo.
Ha e le hantle, ho tjhaja ka potlako ha ho amane ka ho toba le 800V, haholo-holo hobane tekanyo ea ho tjhaja betri e phahame, e lumella ho tjhaja matla a maholo, ao ka boeona ha a amane le 800V, joalo ka sethaleng sa 400V sa Tesla, empa hape se ka finyella ka potlako e kholo. ho tjhaja ka sebopeho sa boemo bo hodimo.Empa 800V ke ho finyella phahameng-matla tjhaja fana ka motheo o motle, hobane e tšoanang ho finyella 360kW tjhaja matla, 800V khopolo feela hloka 450A hona joale, haeba ke 400V, e hloka 900A hona joale, 900A ka maemo a hona joale botekgeniki bakeng sa likoloi tsa baeti ke. hoo e ka bang ha ho kgonehe.Ka hona, hoa utloahala ho hokahanya 800V le tefiso e potlakileng haholo hammoho, e bitsoang 800V super fast charge technology platform.
Hona joale, ho na le mefuta e meraro eamatla a phahamengmeralo ea meralo e lebelletsoeng hore e fihlelle tefiso e potlakileng ea matla a phahameng, mme sistimi e felletseng ea motlakase o phahameng e lebelletsoe ho ba eona e ka sehloohong:
(1) Sisteme e felletseng ea matla a phahameng, ke hore, betri ea matla a 800V + 800V motor, taolo ea motlakase + 800V OBC, DC / DC, PDU + 800V air conditioning, PTC.
Melemo: Sekhahla se phahameng sa phetolo ea matla, mohlala, sekhahla sa phetolo ea matla a sistimi ea ho khanna motlakase ke 90%, sekhahla sa phetolo ea matla a DC / DC ke 92%, haeba sistimi eohle e le matla a phahameng, ha ho hlokahale hore u tebise maikutlo.
