An output power controller in a system having two or more secondary batteries connected in parallel. A battery ECU transfers all the stored electric charge from one secondary battery to another secondary battery when battery temperature and state of charge (SOC) are so low that an output power requirement cannot be satisfied. The SOC of the secondary battery increases by the transfer of the stored electric charge and output power sufficient for the output power requirement can be obtained. Further, the secondary batteries are heated by thermal energy generated by the transfer of the stored electric charge.

Provided is a stator that can reduce iron loss and ensure a fastening force for stator core segments. The stator of a generally hollow cylindrical shape includes a plurality of stator core segments arranged adjacent to one another in a circumferential direction of the stator and each having an outer surface on the outer side in a radial direction of the stator, and the same number of curved members as the stator core segments, the curved members extending in the circumferential direction, and each having a projecting portion curved to project toward the outer surface, contacting the outer surface and pressing the outer surface inward in the radial direction of the stator.

An electric power distribution member for stator is a member for connecting a plurality of coils to one another, each having coil opposing end portions located on an inner circumferential side and on an outer circumferential side in a radial direction of a stator, and it includes a plurality of conductor pieces and a plurality of insulating holding portions. The conductor piece has a first connection end portion in a flat plate shape connected to an inner circumferential side end portion of a coil and a second connection end portion in a flat plate shape connected to an outer circumferential side end portion of another coil. In addition, the insulating holding portion integrally holds adjacent conductor pieces at a distance from each other at a portion other than the opposing connection end portions of each conductor piece. The insulating holding portions are arranged in a manner discrete from one another.

A stator core is formed by arranging divided cores (20) in a circumference direction in cylindrical shape. On an upper end surface (60) of a core back (50) of the divided core, holes (62, 64) are made. Then, on the upper end surface, a reinforcing ring (40) having through holes (66, 68) is arranged, and is connected with rivets (70, 72). Thus, stress is transmitted not only through a side surface (58) but also through the reinforcing ring (40), between the adjacent divided cores. Thus, strength of the stator using a powder magnetic core is ensured and a space is saved.

A driving gear of a vehicle comprising a motor generator (MG2), a power control unit (21) for controlling the motor generator (MG2), and a case for containing the motor generator (MG2) and the power control unit (21). The power control unit (21) comprises a first inverter for driving the motor generator (MG2), and a voltage converter for applying power supply voltage to the first inverter after stepping it up. The voltage converter includes a reactor (L1). Heat of the reactor (L1) is dissipated using lubricant touching the reactor (L1) and the case as heat transfer agent. A circulation path of lubricant is formed in the case and the reactor is arranged on the circulation path.

A die includes a cavity in which a powder magnetic core material is introduced and a recessed curved surface curved inward of the die formed at the bottom surface of the cavity. The powder magnetic core material in the cavity is pressed by a pressing surface of a punch to the side and bottom surfaces of the cavity to form a split tooth body. As a result, a projected curved surface having a shape following the recessed curved surface is formed on the outer peripheral surface of the split tooth body. Then, two split tooth bodies are butted and joined together at the surfaces to which a pressing force by the punch is applied, and thereby a tooth is assembled.
