A battery pack controller is provided having electric wires of the main wiring lines of a precharge circuit laid on the front surface of a base plate. LA terminals (i.e., ring terminals) connected to the electric wires are clamped by screws and the main-circuit bus bars to the relay terminal portions of a main relay mounted on the rear surface. Further, each of the LA terminals (i.e., ring terminals) has a wing portion protruding beyond the protuberant height of an electric-wire connection portion. An electric wire is bent and disposed to extend from the front surface side of the base plate toward the relay terminal portion, a terminal accommodation portion in which the LA terminals (i.e., ring terminals) are accommodated is provided at a part extending from the electric-wire bent portion to the relay terminal portion, and bottom grooves are formed in the terminal accommodation portion into which the wing portions are inserted. |

1. A battery pack controller, comprising:
a base plate, control components including components of a main relay and a precharge circuit mounted on one surface of said main base plate, one pair of terminals with electric wires, which are disposed on the other surface of said base plate and which connect the precharge circuit in parallel with the main relay, a first main circuit bus bar connected to one electrode of a battery pack, and a second main circuit bus bar connected to a lead-out terminal to which an inverter is connected, and an electric wire connection portion having protruding a protuberant height from a plane position of the terminal, wherein one of the terminals with the electric wires and the first main circuit bus bar, and the other of the terminals with the electric wires and the second main circuit bus bar, are respectively clamped to one pair of relay terminal portions of the main relay by screws; each of the terminals with the electric wires has a wing portion which is protruded beyond the protuberant height of the electric wire connection portion from a plane position of the terminal on either a terminal side or an electric wire side of the electric wire connection portion; the electric wires are bent and disposed so as to extend from the other surface side of the base plate toward the relay terminal portions on one surface side and are clamped to the relay terminal portions by the screws together with the first and second main circuit bus bars; and the base plate is formed with a terminal accommodation portion which accommodates the terminal with the electric wire at a part extending from an electric wire bent portion to the relay terminal portion and is formed having grooves into which the wing portion is inserted. |
