Are arranged in the vehicle width direction along the line and connected to temperature sensors (not shown) provided on the junction board 28 and the battery modules 42.
- the main switch 29 is arranged on the upper surface of the central portion of the first battery module group G1, the space between the left and right front seats 30A (see FIG. 1) is used for storing the main switch 29.
- the pressure in the passenger compartment space can be avoided, and the junction board 28 is disposed on the upper surface of the second battery module group G2, so that the space below the rear seat 30B (see FIG. 1) is used to store the junction board 28.
- the main switch 29 and the junction board 28 in the front-rear direction, the vehicle interior space can be secured to the maximum.
- first to third battery module rows R1 to R3 of the first battery module group G1 are connected to the corresponding first to third plurality of battery module rows R1 to R3 of the second battery module group G2, respectively.
- the two high-voltage cables 65 are bent in a U shape and pass below the middle cross member 20. At this time, the bent portions of the second high-voltage cables 65 are held by the three cable holders 69 and are fixed members. 70 is fixed to the battery modules 42 and the battery tray 38, so that the second high-voltage cable 65 is restrained by the cable holder 69 so that the second high-voltage cable 65 tries to extend linearly with its own rigidity.
- a large load is applied to the connection portion connecting the second high-voltage cables 65 to the terminals of the battery modules 42. Waru can be prevented.
- bus bars 74 and 74 are interposed in the middle of the first high voltage cables 68 and 68.
- the wiring work of the first high-voltage cables 68 and 68 is facilitated, and the length of the bus bars 74 and 74 is increased. The reliability with respect to vibration can be improved by minimizing the length.
- the first and second high-voltage cables 68, 68, 65, 65 ′, 66,... are arranged in parallel in the vicinity of the low-voltage cables 76 that transmit the control signal, the first and second high-voltage cables 68, 68, 65 are arranged. ..., 65 '..., 66 ..., a large noise is generated in the control signal flowing through the low-voltage cables 76 ... by the high-voltage current flowing through the ...
- the battery pack 31 is parallel to the first and second high-voltage cables 68, 68, 65... 65 ′, 66.
- the extending low voltage cables 76 are arranged in the front-rear direction on both sides of the battery pack 31 in the vehicle width direction. Therefore, the first and second high voltage cables 68, 68, 65, 65 ′, 66, and the low voltage cable 76 are arranged. ... A large distance can be ensured to reduce noise.
- the low voltage cable 76 approaches the first and second high voltage cables 68, 68, 65... In other words, the low voltage cable 76 and the first and second high voltage cables 68, 68, 65... 65 ′, 66. Noise is reduced because the cables 68, 68, 65... 65 '.
- the battery pack 31 includes the first to third battery module rows R1 to R3, but the number of battery module rows is not limited to three.
