b) the first transport device is caused to bring the first battery out and away from the vehicle along a first path (121) running from the storage space, under a side beam (112) of the vehicle and up to a position above ground and beside the vehicle;
c) the vehicle is caused to assume a second predetermined position, which may be the same as the first predetermined position, in relation to a second transport device (140), which may be the same as the first transport device and which is arranged at least partly above ground and beside the second predetermined position, for automatic transport of a second battery (122) up to and into the vehicle; and
d) the second transport device is caused to bring the second battery up to and into the vehicle along a second path (123) running from a position above ground and beside the vehicle, under a side beam of the vehicle and up to the storage space;
characterised in that, in step b), a hinged door (210;
310;
410;
510), arranged at the underside of the vehicle so that it in a closed position covers the opening, is opened downwards, whereby a part of the first battery, which in this position at least partly is supported by a support surface (213;
313;
413;
505) of the door, becomes available to an engagement device (240;
340) of the first transport device (130), and in that the first engagement device thereafter in step b) engages with or supports the first battery and brings the first battery along the support surface of the door, in a direction with a non-zero horizontal component, away from the storage space and thereafter away from the vehicle along the said first path.

Abstract
Method for battery replacement in a vehicle (110), which vehicle is equipped with a storage space (150;200;300;400) for a battery (120,122;220;320;420;620), where an opening (151;204;304;404) into the storage space exists under the vehicle, wherein the vehicle assumes a first and a second predetermined position in relation to first and second battery transport devices (130;140) that bring a battery out from the vehicle and a battery into the vehicle. The transport devices are installed at least partly above ground (100) and beside the positions, and in that the batteries are brought along a respective path (121,123) running from the storage space, under a side beam (112) of the vehicle and up to a respective position above ground and beside the vehicle. A device for automatic battery replacement and a storage device for use in a vehicle are also described.
