Abstract
An electric vehicle includes a fuel cell unit and a power controller unit that are disposed next to each other in a front compartment. Each of the fuel cell unit and the power controller unit includes an upper casing having a lower strength and a lower casing having a strength greater than that of the upper casing. The fuel cell unit and the power controller unit are arranged so that a distance La between the lower casings along an alignment axis is shorter than a distance Lb between the upper casings along the alignment axis.
Claims10
An electric vehicle comprising:
- a plurality of high voltage units disposed next to each other in a front compartment, when viewed from above the electric vehicle, each of the plurality of high voltage units comprising
- a lower strength portion disposed at either one of an upper side and a lower side of the high voltage unit, and
- a higher strength portion disposed at the other one of the upper side and the lower side of the high voltage unit, the higher strength portion having a strength higher than that of the lower strength portion,
- wherein the plurality of high voltage units are arranged such that a distance between the higher strength portions of the adjacent high voltage units along an alignment axis along which the adjacent high voltage units are disposed next to each other is shorter than a distance between the lower strength portions of the adjacent high voltage units along the alignment axis,
- a casing of each of the higher strength portions of the high voltage units has a wall thickness greater than that of a casing of each of the lower strength portions of the high voltage units,
- the casing of the higher strength portion of at least one of the adjacent high voltage units comprises a raised portion on a surface facing the higher strength portion of the other one of the adjacent high voltage units, the raised portion protruding toward the higher strength portion of the other one of the high voltage units, and
- the adjacent high voltage units are arranged such that a distance along the alignment axis between an outer end of the raised portion and the other one of the high voltage units or between the outer end of the raised portion and an outer end of a raised portion of the other one of the high voltage units is shorter than a distance between the lower strength portions along the alignment axis.
