A power distribution device is connected to a power source connector connected to a battery pack, a front connector connected to a front PCU that supplies power to a front MG, and a rear connector connected to a rear PCU that supplies power to a rear MG. Further, the power distribution device has a DC power connector which may be connected to an external DC power source and an AC power connector which may be connected to an external AC power source. The power source connector, the front connector, and the rear connector are provided on an inner side of the vehicle than the DC power connector and the AC power connector.

Power distribution device

A battery unit is provided which includes a control board, a storage case, a water detector, and an electrical conductor. The storage case is made of an assembly of a first and a second casing member. The first casing member has an upright wall which extends from the bottom thereof and surrounds the battery. The second casing member also has an extension which extends toward the bottom of the first casing member. The water detector is located close to the lower end of the extension of the second casing member. The electric conductor extends upward from the upper end of the extension and are electrically joined to the water detector. The electric conductor is also mechanically and electrically joined to the control board. This structure facilitates the ease with which the water detector is installed electrically and mechanically in the battery unit.

A battery unit is provided which includes a battery and a storage case in which the battery is mounted. The storage case is made up of a base, a cover, and an intermediate case. The cover is jointed to the base with an interspace therebetween. The intermediate case is disposed between the cover and the base and has a peripheral wall which occupies the interspace. The intermediate case is lower in stiffness than the cover and the base, thereby realizing a lightweight structure of the storage case without sacrificing the mechanical strength thereof.

Lightweight and rigid structure of battery unit

In an engine starting apparatus, together with a one-way clutch, a pinion is pushed toward a ring gear of an engine mounted in a vehicle. The one-way clutch has an idling torque smaller than a torque of the ring gear that tries to turn the pinion when the pinion is pushed to the ring gear. By a control device, a pinion pushing device is enabled to operate when i) the revolution speed of the ring gear is larger than a revolution speed of the pinion and ii) a relative revolution speed between the revolution speed of the ring gear and the revolution speed of the pinion is a desired value.

Engine starting apparatus

A first coil constitutes a first coil unit by placing an iron core plate between the first coil and an auxiliary yokes and engaging stopping parts provided in two holding members to an end surface in an axial direction of the auxiliary yoke. A second coil constitutes a second coil unit by forming magnetic path members by insertion to a resin member provided in a second bobbin unitarily, and fixing two terminals to the resin member. The first and the second coil units are united by connecting one terminal lead line of the first coil taken out from holding members to the first terminal, and connecting another terminal lead line to a surface of the magnetic path member.
