Tiyenera kuganizira osati momwe mphamvu imasungidwira, komanso momwe imasunthidwira popanda kutayika kwakukulu komanso kuwongolera kwakukulu. Mu chaputala chino, tikuyerekeza njira ziwiri zazikulu zolumikizira: makina olumikizidwa ndi AC ndi DC.

1.1 Kapangidwe ka AC-Coupled: Cholowa ndi Zokonzanso

Mu makina olumikizidwa ndi AC, BESS ndi EVSE zimalumikizidwa ku basi yayikulu ya AC ya siteshoni, nthawi zambiri pa 400V kapena 480V. BESS ili ndi Power Conversion System (PCS) yake yomwe imasintha AC kuchokera ku gridi kupita ku DC kuti isungidwe. Chaja iliyonse ya EV ilinso ndi chosinthira chake chamkati cha AC-DC (rectifier).

Ubwino waukulu wa AC-coupling ndi modularity yake. Chifukwa BESS ndi ma charger ndi zida zodziyimira pawokha zolumikizidwa ku AC grid, zimatha kupezeka kuchokera kwa ogulitsa osiyanasiyana ndikusinthidwa padera. Izi zimapangitsa AC-coupling kukhala chisankho chomwe chimakondedwa pokonzanso malo omwe alipo ochajira. Komabe, magwiridwe antchito ndi otsika. Taganizirani za momwe EV imachajidwira pogwiritsa ntchito mphamvu yosungidwa mu BESS. Mphamvuyo iyenera kudutsa magawo atatu osinthira:
