<p>A method for exchanging batteries in battery-powered vehicles, comprising a robot (1) for the transport of a battery (2) to and from the vehicle (3). The invention is characterised in that the vehicle (3) is provided with a horizontally placed compartment (4) for one or several batteries (2) lying parallel to each other, in that the robot (1) is provided with a transport plane (6) that can be extended and withdrawn in one direction (9), in that the transport plane (6) can be displaced also along two mutually perpendicular directions (10, 11) relative to the said direction (9). The vehicle (3) is caused to take up a predetermined location relative to the robot (1) close to the cover, in that the robot is caused to determine by means of an optical means (15) the position of the battery in the compartment (4), in that the robot is caused to displace the said transport plane (6) to a predetermined position relative to the battery, in that a withdrawal means (17-20) is caused to be attached to the battery in the said compartment, in that the battery is withdrawn from the said compartment with the withdrawal means to the transport plane (6), in that the robot (1) is caused to transport the battery to a charging station (21), in that the robot (1) is caused to transport a charged battery from a store (21) of charged batteries to the said transport plane (6), in that a displacement means (17- 20) is caused to insert at a predetermined position the battery (2) into the said compartment (4), and in that the cover (5) is caused to be closed.</p> |
