An electric vehicle 10 comprising a traction battery 12 for providing electric power for an electric drivetrain 14 of the electric vehicle, the electric vehicle comprising a charging compartment 16 and a portable battery (18) removably storable in the charging compartment, wherein a socket 20 for a charging interface 22 of the portable battery is arranged in the charging compartment, via which socket and charging interface the traction battery is chargeable by the portable battery. The portable battery may have a higher energy density than the traction battery. The socket of the charging compartment may be configured for bidirectional charging so that that the portable battery is chargeable by the traction battery. The portable battery, in addition to the charging interface, may have a charging connector 24 via which the portable battery can be charged by an external charger. The portable battery may be operatable with a low or a high operating voltage. An on-board low voltage battery with a low operating voltage may be provided, and this may be chargeable via the socket, and the on-board low-voltage battery may be configured for a jump start. The charging compartment may be arranged in a trunk 30 or a lockable compartment.
