1. Nhanganyaya kune DC yekuchaja murwi
Mumakore achangopfuura, kukurumidza kukura kwemotokari dzemagetsi (EVs) kwakafambisa kudiwa kwemhinduro dzakasimba uye nehungwaru dzekuchaja. DC yekuchaja mirwi, inozivikanwa nekukasira kuchaja masimba, ari kumberi kweshanduko iyi. Nekufambira mberi mune tekinoroji, majaja eDC anonyatso gadzirirwa kukwidziridza nguva yekuchaja, kunatsiridza mashandisiro esimba, uye kupa mubatanidzwa usina musono neakangwara grid.
Nekuenderera mberi kwekuwedzera kwehuwandu hwemusika, kuiswa kwebidirectional OBC (On-Board Charger) haingobatsiri kudzikisira kushushikana kwevatengi nezve huwandu uye kubhadharisa kushushikana nekugonesa kuchaja nekukurumidza asi zvakare kunobvumira mota dzemagetsi kuti dzishande seyakagoverwa magetsi ekuchengetedza zviteshi. Idzi mota dzinogona kudzosera simba kune grid, kubatsira mukuveura ndebvu uye kuzadza mupata. Kuchaja kwakanaka kwemotokari dzemagetsi kuburikidza neDC inokurumidza charger (DCFC) itsika huru mukusimudzira shanduko yesimba rinogoneka. Ultra-inokurumidza kuchaja zviteshi inobatanidza zvinhu zvakasiyana-siyana senge simba rekubatsira, masensa, manejimendi emagetsi, uye michina yekutaurirana. Panguva imwecheteyo, nzira dzekugadzira dzinochinjika dzinodiwa kuti dzizadzise zviri kuitika zvekuchaja zvinodiwa zvemotokari dzemagetsi dzakasiyana, zvichiwedzera kuomarara kudhizaini yeDCFC uye zviteshi zvekuchaja zvinokurumidza.
Musiyano uripo pakati pekuchaja kweAC neDC kuchaja, yekuchaja kweAC (kuruboshwe rweMufananidzo 2), plugi OBC mune yakajairika AC outlet, uye OBC inoshandura AC kuenda kuDC yakakodzera kuchaja bhatiri. Yekuchaja DC (kurudyi kweMufananidzo 2), positi yekuchaja inochaja bhatiri zvakananga.

Level 3 (L3) DC inokurumidza majaja anopfuura ne-on-board charger (OBC) yemotokari yemagetsi nekuchaja bhatiri zvakananga kuburikidza neEV's Battery Management System (BMS). Iyi bypass inotungamira kukuwedzera kukuru kwekuchaja, nechaja inobuda simba kubva pa50 kW kusvika 350 kW. Iyo inobuda magetsi inowanzosiyana pakati pe400V ne800V, ine maEV matsva anoenda ku800V bhatiri masisitimu. Sezvo L3 DC inokurumidza majaja ichishandura matatu-phase AC yekupinza voltage kuita DC, vanoshandisa AC-DC simba factor kugadzirisa (PFC) kumberi-kumagumo, iyo inosanganisira yakasarudzika DC-DC inoshandura. Iyi PFC inobuda inobva yabatanidzwa nebhatiri remotokari. Kuti uwane yakakwira simba rekubuda, akawanda emagetsi mamodule anowanzo kubatanidzwa mukufanana. Kubatsira kukuru kweL3 DC inokurumidza majaja ndiko kudzikiswa kwakanyanya kwekuchaja nguva yemotokari dzemagetsi
Iyo yekuchaja murwi musimboti ndeye yakakosha AC-DC inoshandura. Iyo ine PFC nhanho, DC bhazi uye DC-DC module

3. Kuchaja murwi scenario scheme
(1) Optical yekuchengetedza yekuchaja system
Sezvo simba rekuchaja remotokari dzemagetsi richiwedzera, simba rekugovera magetsi pazviteshi zvekuchaja rinowanzonetsekana kuzadzisa zvinodiwa. Kuti ugadzirise nyaya iyi, yabuda nzira yekuchaja yakavakirwa pakushandisa bhazi reDC. Iyi sisitimu inoshandisa mabhatiri e-lithium sesimba rekuchengetedza simba uye inoshandisa yemuno uye kure EMS (Energy Management System) kuenzanisa nekugadzirisa kupihwa uye kudiwa kwemagetsi pakati pegridi, mabhatiri ekuchengetedza, uye mota dzemagetsi. Pamusoro pezvo, iyo sisitimu inogona kusanganisa nyore nyore ne photovoltaic (PV) masisitimu, ichipa zvakakosha zvakakosha mukukwirira uye kure-peak mitengo yemagetsi uye grid kuwedzera simba, nekudaro ichivandudza kugona kwesimba rose.
(2) V2G yekuchaja system
Vehicle-to-Grid (V2G) tekinoroji inoshandisa mabhatiri eEV kuchengetedza simba, inotsigira giredhi remagetsi nekugonesa kudyidzana pakati pemotokari negridi. Izvi zvinodzikisira kunetsa kunokonzerwa nekubatanidza masimba makuru anogona kudzokororwazve uye kupararira kweEV kuchaja, pakupedzisira kunosimudzira kugadzikana kwegidhi. Pamusoro pezvo, munzvimbo dzakaita senzvimbo dzekugara uye mahofisi emahofisi, mota dzemagetsi dzakawanda dzinogona kutora mukana wepamusoro-soro uye kure-yepamusoro mitengo, kutonga kuwedzera kwemutoro, kupindura kudiwa kwegridi, uye kupa simba rekuchengetedza, zvese kuburikidza nepakati EMS (Energy Management System) control. Kudzimba, Vehicle-to-Home (V2H) tekinoroji inogona kushandura mabhatiri eEV kuita chigadziro chekuchengetedza simba repamba.
(3) Yakaraira yekuchaja system
Iyo yakaodha yekuchaja sisitimu inonyanya kushandisa yakakwirira-simba inokurumidza kuchaja zviteshi, yakanakira yakatarisana yekuchaja zvinodiwa senge ruzhinji rwekufambisa, matekisi, uye kutakura zvinhu. Mashedhi ekuchaja anogona kugadziridzwa zvichienderana nemhando dzemotokari, nekuchaja kunoitika panguva yekusa-peak magetsi maawa kudzikisa mitengo. Pamusoro pezvo, ine hungwaru manejimendi sisitimu inogona kuitwa kuti ifambise pakati pepakati pezvikepe manejimendi.
4.Future development trend
(1) Kubudirira kwakarongeka kwezviitiko zvakasiyana-siyana zvinowedzerwa nechepakati + yakagoverwa yekuchaja zviteshi kubva kune imwe chete yepakati yekuchaja zviteshi.
Kwekuenda-kwakavakirwa kugoverwa kuchaja zviteshi zvichashanda sekuwedzera kwakakosha kune yakawedzera kuchaja network. Kusiyana nezviteshi zvepakati apo vashandisi vanoshingairira kutsvaga majaja, zviteshi izvi zvichabatana munzvimbo dzave kutoshanya nevanhu. Vashandisi vanogona kuchaja mota dzavo panguva yekugara kwenguva refu (kazhinji kweawa imwe), uko kumhanyisa kuchaja kusingakoshese. Simba rekuchaja rezviteshi izvi, rinowanzobva pamakumi maviri kusvika pamakumi matatu kW, rinokwana mota dzevatyairi, zvichipa mwero unonzwisisika wesimba kuti usangane nezvinodiwa zvakakosha.
(2) 20kW hombe share musika kusvika 20/30/40/60kW diversified configuration musika kuvandudza
Nekuchinja kuenda kumotokari dzemagetsi emagetsi akakwira, pane kudikanwa kwekuwedzera iyo yakanyanya kuchaja voltage yekuchaja mirwi kusvika ku1000V kuti ienderane neramangwana rakapararira kushandiswa kwemamodhi e-high-voltage. Kufamba uku kunotsigira kuvandudzwa kwezvivakwa zvezviteshi zvekuchaja. Iyo 1000V yekubuda kwevoltage standard yakawana kugamuchirwa kwakafara muindasitiri yekuchaja module, uye vagadziri vakakosha vari kuunza zvishoma nezvishoma 1000V high-voltage kuchaja module kuti isangane nechido ichi.
Linkpower yakatsaurirwa kupa R&D inosanganisira software, Hardware uye chitarisiko che AC/DC yemagetsi mota yekuchaja mirwi kweanopfuura makore masere. Isu takawana ETL / FCC / CE / UKCA / CB / TR25 / RCM zvitupa. Tichishandisa OCPP1.6 software, tapedza kuyedza nevanopfuura zana OCPP vanopa papuratifomu. Takavandudza OCPP1.6J kusvika kuOCPP2.0.1, uye mhinduro yeEVSE yekutengeserana yakashongedzerwa neIEC/ISO15118 module, inova danho rakasimba pakuona V2G bi-directional kuchaja.
Mune ramangwana, zvigadzirwa zvepamusoro-soro zvakadai semotokari yemagetsi yekuchaja mirwi, solar photovoltaic, uye lithium bhatiri simba rekuchengetedza masisitimu (BESS) ichagadzirwa kuti ipe nhanho yepamusoro yemhinduro dzakabatanidzwa kune vatengi pasi rese.
