Multifunctional charging topology for electric vehicle

A method of assembling a system in a vehicle, the method comprising:

• arranging a first winding section including first two or more windings;
• arranging a second winding section including second two or more windings, each of the second two or more windings corresponding to one of the first two or more windings of the first winding section;
• arranging an inverter including a high side switch and a low side switch corresponding to each of the first two or more windings;
• coupling the inverter to a battery of the vehicle;
• and configuring the inverter to boost a voltage of a direct current (DC) charger during charging of the battery with the DC charger, to convert alternating current (AC) from an AC grid to DC during charging of the battery with the AC grid, and to convert DC to AC during supply of the AC grid by the battery and positioning two or more switches such that each of the two or more switches are controlled to close to connect the first two or more windings of the first winding section to a corresponding one of the second two or more windings of the second winding section and controlled to open to galvanically isolate the first two or more windings from the second two or more windings during the charging of the battery with the AC grid.
