Abstract: A charging system includes: a main battery storing electric power for a vehicle to travel; an inlet connected to a charging connector; a charging relay that switches a path of electric power from the inlet to the main battery; a converter that steps down a voltage of the electric power from the inlet; and an ECU that controls the charging relay and the converter. The ECU: controls the converter so that the converter starts stepping down the voltage of the electric power from the inlet to the auxiliary voltage after receiving the electric power from the inlet; supplies, before the charging relay switches to the connected state, the charging relay with the electric power from the converter as operating power for switching to the connected state; and controls the charging relay so that the charging relay switches from the disconnected state to the connected state, using the operating power.

Abstract: The charging device mounted on electrified vehicle includes: a first charger capable of converting AC power supplied from the outside to DC power supplied to the battery; a second charger capable of converting AC power supplied from the outside to DC power supplied to the battery, and capable of converting DC power supplied from the battery to AC power supplied to the outside; a DC-to-DC converter capable of converting DC power supplied from the battery to low-voltage DC power supplied to the auxiliary battery; a relay for electrically connecting and disconnecting the DC charging inlet to the battery; and a housing including a first chamber for accommodating the second charger, a second chamber for accommodating the first charger and the relay, and a third chamber for accommodating DC-to-DC converter.

Abstract: A power supply unit accommodates a main DC/DC converter and an AC charger (a charging circuit, a sub-DC/DC converter) in a housing. The main DC/DC converter and the sub-DC/DC converter are arranged in the same tier of the housing. The charging circuit is arranged in a tier different from that of the main DC/DC converter and the sub-DC/DC converter. The main DC/DC converter and the sub-DC/DC converter arranged in the same tier of the housing are controlled to operate in a mutually exclusive manner.

Abstract: The present disclosure relates to an in-vehicle charger capable of reducing the influence of electromagnetic waves on an external environment. The in-vehicle charger is disposed in an engine compartment. The in-vehicle charger includes a first charger and a second charger. The second charger is disposed closer to a hood than the first charger.

Abstract: A coil module includes: a coil formed by winding a coil wire; and an insulating member. The coil includes a first wound portion and a second wound portion, the first wound portion being formed to surround the winding axis, the second wound portion being formed at a position adjacent to the first wound portion on an outer perimeter side of the coil. The insulating member includes a first insulating portion configured to cover a perimeter surface of the first wound portion, and a second insulating portion configured to cover a perimeter surface of the second wound portion. A portion of a surface of the first insulating portion located on the outer perimeter side of the coil is in contact with a portion of a surface of the second insulating portion located on the winding axis side.

Abstract: A coil unit includes a coil and an accommodation case accommodating the coil. The coil is formed of a coil wire wound around a winding axis. A hollow portion is formed in a position in which the winding axis passes. The coil includes an outer peripheral portion located in an outer peripheral edge of the coil, and an inner peripheral portion located along an inner peripheral edge of the coil. A voltage on the inner peripheral portion is higher than a voltage on the outer peripheral portion.

Abstract: A coil unit includes a case (an upper cover) made of a resin, the case including an attachment surface to be attached to a case of a power storage apparatus, a metal plate provided in the case, a coil located opposite to the attachment surface with respect to the metal plate, and a metal member arranged to surround a space portion located between the metal plate and the case (the upper cover). The metal member is formed integrally with the upper cover made of the resin.
