A car battery array is provided with battery blocks (2) having a plurality of connected batteries (1), a first load-bearing plate (3) on top of which the battery blocks are mounted, a second load-bearing plate (4) attached on both sides to the first load-bearing plate and covering the tops of the ba
A car battery array is provided with battery blocks (2) having a plurality of connected batteries (1), a first load-bearing plate (3) on top of which the battery blocks are mounted, a second load-bearing plate (4) attached on both sides to the first load-bearing plate and covering the tops of the battery blocks, and a reinforcing rod (5) that connects with the second load-bearing plate and the battery blocks to attach the second load-bearing plate to the battery blocks. The battery blocks are disposed in a battery compartment (6) established inside the first and second load-bearing plates, which are joined together on both sides. The battery blocks are mounted on top of the first load-bearing plate and connected to the second load-bearing plate via the reinforcing rod to support the battery block load with the first load-bearing plate and the second load-bearing plate.

The car battery array as recited in claim 1, wherein the second load-bearing plate has a trough-shape with side-walls on both sides, the reinforcing rod is disposed in a base section of the second load-bearing plate between the two side-walls extending in a lengthwise direction of the side-walls, and the reinforcing rod is attached to the battery blocks and to the base section of the second load-bearing plate. 3. The car battery array as recited in claim 1, wherein the first load-bearing plate and the second load-bearing plate are trough-shaped metal plates. 4. The car battery array as recited in claim 1, wherein the battery blocks are provided with a plurality of battery cells stacked together, with endplates that sandwich both ends of a battery cell stack, and the first load-bearing plate and the second load-bearing plate are attached to the battery block endplates. 5. The car battery array as recited in claim 4, wherein the reinforcing rod extends in a direction of the stacked battery cells and is attached to the second load-bearing plate. 6. The car battery array as recited in claim 4, further comprising a second reinforcing rod, wherein the reinforcing rods are exhaust ducts for gas discharged from the battery blocks, and the exhaust duct reinforcing rods are attached to the endplates and the second load-bearing plate to attach the second load-bearing plate to the battery blocks. 7. The car battery array as recited in claim 6, wherein the exhaust ducts serving the dual purpose as reinforcing rods are attached to battery block endplates. 8. The car battery array as recited in claim 6, wherein the exhaust ducts serving the dual purpose as reinforcing rods are disposed as parallel exhaust ducts, and the exhaust ducts reinforce the second load-bearing plate. 9. The car battery array as recited in claim 6, wherein the exhaust ducts serving the dual purpose as reinforcing rods are attached to the second load-bearing plate via set screws inserted through the second load-bearing plate. 10. The car battery array as recited in claim 4, wherein the battery blocks are disposed in a plurality of rows and mounted between the first load-bearing plate and the second load-bearing plate, cooling ducts are established between adjacent battery blocks, a cooling duct sealing plate that closes off the top of one of the cooling ducts is the reinforcing rod, and the reinforcing rod as the cooling duct sealing plate is attached to the battery block endplates and to the second load-bearing plate to attach the second load-bearing plate to the battery blocks. 11. The car battery array as recited in claim 10, wherein the cooling duct sealing plate serving the dual purpose as the reinforcing rod is a metal plate formed in a rail-shape. 12. The car battery array as recited in claim 10, wherein the cooling duct sealing plate serving the dual purpose as the reinforcing rod is attached via set screws to tops of the endplates of the battery blocks on both sides of the cooling duct. 13. The car battery array as recited in claim 10, wherein the cooling duct sealing plate serving the dual purpose as the reinforcing rod has fastening nuts mounted with separation above the cooling duct sealing plate via mounting pieces having mounting legs, and set screws inserted through the second load-bearing plate are screwed into the fastening nuts to attach the cooling duct sealing plate to the second load-bearing plate via the set screws. 14. The car battery array as recited in claim 10, wherein the cooling duct sealing plate serving the dual purpose as the reinforcing rod extends in a lengthwise direction along a center of the second load-bearing plate to reinforce the second load-bearing plate. 15. The car battery array as recited in claim 1, wherein the second load-bearing plate has trough-shape depressions protruding downward in sections attached to the reinforcing rod, through-holes are provided for set screw insertion at the bottoms of those trough-shaped depressions, and set screws inserted through the through-holes are screwed into the reinforcing rod to attach the reinforcing rod to the second load-bearing plate. 16. The car battery array as recited in claim 1, wherein tops of the battery blocks are attached to the reinforcing rod at attachment points offset from directly above bottom attachment points where bottoms of the battery blocks are attached to the first load-bearing plate. 17. The car battery array as recited in claim 1, wherein the first load-bearing plate and the second load-bearing plate have trough-shapes with side-walls, the side-walls of the second load-bearing plate are attached to the first load-bearing plate side-walls or a base section of the first load-bearing plate to form an external case having a battery block storage compartment, and the side-walls of the external case are separated from the side surfaces of the battery blocks to establish side cooling ducts between the battery blocks and the side-walls. 18. The car battery array as recited in claim 17, wherein an electronic component case for housing electronic components is disposed outside one of the side cooling ducts and outside the external case side-wall that establishes that side cooling duct. 19.
