a first heat-generating component disposed in the rear portion (103) of the electric vehicle (100); and
a duct (114, 1306) having a portion disposed above the battery (104), wherein the duct (114, 1306) extends rearwards from the front portion (102) towards the first heat-generating component to conduct air from the front portion (102) to the first heat-generating component.
2. The electric vehicle (100) as claimed in claim 1, comprising a second
heat-generating component disposed in the cavity (316), wherein the duct
(114, 1306) comprises:
an inlet (222) facing the front portion (102) to receive air from the front portion (102);
a first outlet (402) facing the first heat-generating component to supply air to the first heat-generating component; and
a second outlet (502) facing the second heat-generating component to supply air to the second heat-generating component.
3. The electric vehicle (100) as claimed in claim 2, comprising:
a front wheel (106) disposed in the front portion (102); and

a front wheel fender (204) disposed above the front wheel (106), wherein the inlet (222) of the duct (114, 1306) positioned above the front wheel fender (204), to receive air from.
4. The electric vehicle (100) as claimed in claim 3, comprising:
a suspension bracket (216) disposed above the front wheel fender (204), wherein the inlet (222) of the duct (114, 1306) faces a gap (220) between the front wheel fender (204) and the suspension bracket (216).
5. The electric vehicle (100) as claimed in claim 4, wherein the suspension bracket (216) is one of: a convex-shaped and a flat shaped relative to the gap (220).
6. The electric vehicle (100) as claimed in claim 4, wherein a top surface (1102) of the front wheel fender (204) is one of: a concave-shaped and a convex-shaped, relative to the gap, to guide the air into the duct (114, 1306).
7. The electric vehicle (100) as claimed in claim 1, comprising a front panel (105) disposed at the front portion (102), wherein the duct (114, 1306) comprises:
a first front duct member (1308) extending rearwards from a front surface (1311) of the front panel (105); and
