1. A fastening apparatus for a battery in a motor vehicle, the battery having a base section and opposite first and second sides extending from the base section, the base section including first and second recesses disposed respectively at the first and second sides of the battery comprising: a carrier device for carrying the battery, the carrier device having a first fastening point in proximity to the first side of the battery and a second fastening point in proximity to the second side of the battery, the first fastening point including an edge projecting up partly along the first side of the battery and into the first recess for holding the battery in proximity to the carrier device;a flexible clamping strap that encloses the battery at least in sections, the clamping strap having opposite first and second end sections, the first end section being fastened to a lower surface of the carrier device at the first fastening point;a clamping element having a coupling coupled to the second end section of the clamping strap, the clamping element including a lug projecting into the second recess for holding the battery in proximity to the carrier device and having a through hole opposed to the second fastening point of the carrier device, the through hole being disposed so that the coupling is between the lug and the through hole; andan actuating element passing through the through hole of the clamping element and disposed on a side of the coupling outward of the battery, the actuating element being adjustably engaged with the second fastening point for moving the clamping element toward the second fastening point and setting a prestress in the clamping strap between the first and second end sections and connecting the second end section of the clamping strap to the carrier device. 2. The fastening of claim 1, wherein the carrier device has a battery carrier with a framework structure. 3. The fastening of claim 2, wherein the carrier device has a battery shell for receiving the battery, the battery shell being arranged between the battery carrier and the battery. 4. The fastening apparatus of claim 3, wherein the battery shell is an integral constituent part of the battery carrier. 5. The fastening apparatus of claim 1, wherein the first end section of the clamping strap is screwed to the first fastening point of the carrier device. 6. The fastening apparatus of claim 1, wherein the clamping element is configured so that an end face of the clamping element is spaced from the carrier device after setting the prestress in the clamping strap. 7. The fastening apparatus of claim 1, wherein the second fastening point of the carrier device has a threaded hole, and the actuating element is a threaded screw passing through the through hole of the clamping element and engaged in the threaded hole of the second fastening point. 8. The fastening apparatus of claim 1, further comprising a spring element extending from the second end section of the clamping strap to the second fastening point of the carrier device for maintaining the settable prestress in the clamping element. 9. The fastening apparatus of claim 1, wherein the clamping strap is a flexible but substantially inextensible clamping strap formed from a high strength woven plastic fabric. 10. The fastening apparatus of claim 1, further comprising an eyelet or a belt end fitting sewn to the first end section of the clamping strap for fastening to the first fastening point of the carrier device. 11. A motor vehicle, comprising: a battery having a base section and opposite first and second sides extending from the base section, the base section including first and second recesses disposed respectively at the first and second sides of the battery; anda fastening apparatus including:a carrier device for carrying the battery, the carrier device having a first fastening point in proximity to the first side of the battery and a second fastening point in proximity to the second side of the battery, the first fastening point including an edge projecting up partly along the first side of the battery and into the first recess for holding the battery in proximity to the carrier device;a flexible clamping strap that encloses the battery at least in sections, the clamping strap having opposite first and second end sections, the first end section being fastened to a lower surface of the carrier device at the first fastening point;a clamping element having a coupling coupled to the second end section of the clamping strap, the clamping element including a lug projecting into the second recess for holding the battery in proximity to the carrier device and having a through hole opposed to the second fastening point of the carrier device, the through hole being disposed so that the coupling is between the lug and the through hole; andan actuating element passing through the through hole of the clamping element and disposed on a side of the coupling outward of the battery, the actuating element being adjustably engaged with the second fastening point for moving the clamping element toward the second fastening point and setting a prestress in the clamping strap between the first and second end sections and connecting the second end section of the clamping strap to the carrier device.
