What is claimed is: 1. Battery exchange system for a battery-driven industrial truck, in which the chassis of the industrial truck comprises a battery compartment open to the side of the industrial truck for side installation and removal of a battery container, characterized in that on at least two opposing sides on the upper edge (8) of the battery container (14, 28) at least one eye (42) is provided and support strips (20, 22, 46, 48) are attached to the eyes (42), the strips having downwardly facing bearing surfaces and the battery compartment (14) on opposing sides comprises horizontal support surfaces (26) spaced apart from one another in parallel on which the support strips are supported with their bearing surfaces, when the battery container (16, 28) is inserted into the battery compartment (14). 2. Battery exchange system according to claim 1, characterized in that the support strips form a frame (20, 22) surrounding the battery container (28). 3. Battery exchange system according to claim 1, characterized in that two U-shaped support elements (46, 48) are attached to the battery container (28) on opposing sides. 4. Battery exchange system according to claim 1, characterized in that the support strips are attached in the upper region of the battery container and at the top approximately adjoin the upper edge thereof. 5. Battery exchange system according to claim 1, characterized in that the bearing surfaces are arranged between the upper and lower face of the battery container. 6. Battery exchange system according to claim 1, characterized in that the width of the battery compartment (14) is only slightly larger than the dimensions of the battery container (28) and the support surfaces (26) are laterally set back. 7. Battery exchange system according to claim 1, characterized in that the support strips comprise a pin-shaped projection (11). 8. Battery exchange system according to claim 1, characterized in that a casing for the battery compartment is attached to the support element facing the opening of the battery compartment (14). 9. Battery exchange system according to claim 1, characterized in that the lateral opening of the battery compartment (14) may be sealed by a flap (80) which is attached to the chassis of the industrial truck (10). 10. Battery exchange system according to claim 1, characterized in that in the battery compartment (14) at least one clamping element (7) is provided which laterally engages a received battery container. 11. Battery exchange system according to claim 1, characterized in that the battery compartment (14) is open at the bottom to such an extent that the fork arms of a forklift may grip the battery container from below. 12. Battery exchange system according to claim 1, characterized in that between the support strips and the battery compartment a cooperating telescopic guide (1) is provided for removing the battery container (28) in the manner of a drawer from the battery compartment (14). 13. Battery exchange system according to claim 1, characterized in that the battery container (28) may be removably attached to the support strips (20). 14. Battery exchange system according to claim 1, characterized in that a lifting device (72 to 77) is arranged between the support strips (64) and the battery container (28). 15. Battery exchange system according to claim 1, characterized in that a lifting device (60, 62) is arranged between the support surfaces (60) and the support frame (20). 16. Battery exchange system according to claim 1, characterized in that the support strips comprise two insertion pockets (13) spaced apart from one another in parallel, the opening thereof facing the opening of the battery compartment (14) and a C-shaped hook (14) is provided with two arms (30) spaced apart from one another in parallel which may be inserted into the insertion pockets (14). 17. Battery exchange system according to claim 1, characterized in that a support strip comprises an integrated first contact arrangement (12) which cooperates with a second contact arrangement (11a) on the vehicle side when the battery container (28) is inserted into the battery compartment (14). 18. Battery exchange system according to claim 1, characterized in that on the support ustrip (48) first locking means (4) are provided which cooperate with second locking means (3) in the battery compartment (14). 19. Battery exchange system according to claim 7, characterized in that the pin-shaped projection may be secured by a split pin. 20. Battery exchange system according to claim 7, characterized in that the pin-shaped projection (11) comprises a spring-biased detent catch (9), which lockingly engages behind the rear edge of the eye (42) when the pin-shaped projection (11) is inserted into the eye (42). 21. Battery exchange system according to claim 10, characterized in that the clamping element is formed by a spring-loaded catch (7). 22. Battery exchange system according to claim 10, characterized in that the clamping element may be actuated for selective engagement with the battery container. 23. Battery exchange system according to claim 12, characterized in that a supporting device (36) is associated with the support strips, which laterally supports the industrial truck (10) when the battery container (28) is removed to the side. 24. Battery exchange system according to claim 23, characterized in that the supporting device is configured such that it is automatically moved into a support position, when the battery container (28) is removed. 25.
