Kodwa-ke, ukuwohloka akukona umugqa-ulahlekelwa amandla ngokushesha eminyakeni engu-1-2, bese ukuwohloka kuyehla. Amasistimu aklanywe kahle enza lokhu ngokuqala ukweqa umthamo ngo-10-15%.
Ingabe ibhethri lamandla kagesi aphezulu liphephile kunezinhlelo ezingu-48V zokufakwa kwe-DIY?
Cha. Noma iyiphi i-voltage engaphezu kuka-70V DC iveza izingozi ezibulalayo ezidinga ukuphathwa ngochwepheshe. Umkhawulo we-48V ukhona ngokukhethekile ukuze ugcine ukufakwa kwe-DIY kububanzi bokushaqeka okusinda. Uma uhlela umnikazi-amasistimu asebenzisekayo, i-48V ihlinzeka ngemajini yokuphepha ebalulekile. I-voltage ephezulu idinga ukufakwa nokugcinwa kochwepheshe.
Iyiphi ikhemistri esebenza kangcono ekushiseni okukhulu?
I-LFP igcina ukusebenza okungcono ekushiseni. Isebenza kufika ku-60℃, i-LFP yehlisa ngo-30-40% kancane kune-NMC emazingeni okushisa aqhubekayo. Ezindaweni ezinamazinga okushisa avamile angu-40 + (i-Middle East, ingaphakathi lase-Australia), i-LFP ibonisa iminyaka engu-2-3 yokuphila ende kune-NMC lapho kokubili kupholile emoyeni.
Ngiwenza kanjani usayizi webhethri wekhaya lami?
Qala ngokusetshenziswa kwansuku zonke susa ukusetshenziswa kwe-solar{0}}. Ikhaya elimaphakathi lase-US lisebenzisa u-30 kWh nsuku zonke. Njengoba isistimu yelanga engu-5 kW idla u-40%, udinga u-18 kWh. Engeza isigcinalwazi esingu-20% sokulahlekelwa okusebenzayo kanye nokuwohloka: ~22 kWh inani. Umjikelezo kumasayizi atholakalayo: 20-25 kWh uhlelo. Ungakhulisi ngaphezu kokungu-1.5x umjikelezo wakho wamabhethri amakhudlwana okuhlosiwe ngawo izikhathi ezimbalwa, wonakala ngokushesha ngonyaka wempilo yekhalenda.
Ingabe amabhethri aqinile-azoshintsha indawo ye-lithium{1}}i-ion ukuze igcinwe?
Hhayi eminyakeni engu-5-7 elandelayo. Ubuchwepheshe bezwe-eliqinile buthembisa ukuminyana kwamandla nokuphepha okuphezulu, kodwa izindleko zamanje zokukhiqiza zeqa u-$300/kWh-6x ngaphezu kwe-LFP. I-Toyota iqondise u-2027 kumabhethri e-EV solid-state, kodwa isitoreji esimile sibeka phambili izindleko ngaphezu kokuminyana. I-Solid-state cishe izofaka izicelo zokuhlala eziphakeme kuqala, izohlala ibiza kakhulu kwigridi yokugcina kuze kube 2032+.
