摘要： A powertrain includes a first and second switch coupled in parallel to drive an electric machine and a gate driver. The gate driver may be configured to, in response to a transition request while a first temperature of the first switch exceeds a second temperature of the second switch, inject a current onto a gate of the second switch to drive rates of change of current through the first and second switch to the electric machine to a same value.

摘要： An electric vehicle receives electric power, in a non-contact manner, from an electric power transmitting coil provided externally to the vehicle. The electric vehicle includes an electric power receiving unit that is disposed at a bottom of the vehicle and receives electric power from the electric power transmitting unit via electromagnetic field resonance; a camera that captures an image of the outside; and a display unit that displays an outside view from the vehicle that is captured by the camera. The electric power receiving unit is disposed at a position that is offset toward a peripheral face, on which the camera is disposed, with respect to the center of the bottom in the longitudinal direction of the vehicle.

摘要： In a power storage system, a bidirectional DC-DC converter is set into mode for charging a secondary battery with electricity when a first state of charge (SOC) of the secondary battery is larger than a minimum value of the first SOC, and a second SOC of the capacitor is smaller than a maximum value of the second SOC, and the converter is set into mode for discharging electricity from the secondary battery when the first SOC is smaller than a maximum value of the first SOC, and the second SOC is larger than a minimum value of the second SOC. Based on an internal resistance of the secondary battery, the second SOC, a voltage of a direct current link in case of no load connected to DC link, and an error in a current on a direct current link side, a conduction ratio (D) of the converter is calculated.

摘要： An electrically powered vehicle includes a power storage device, a motor, a limitation control unit, a notification unit, and a changing unit. The motor generates traveling driving power using electric power output from the power storage device. The limitation control unit limits possible output power, which indicates electric power able to be output from the power storage device, based on a load state of the power storage device. The notification unit notifies a warning when the possible output power is smaller than a threshold value for notifying a driver of decrease of the traveling driving power. The changing unit increases, when the load state of the power storage device is high, the threshold value to be larger than the threshold value when the load state of the power storage device is low.

摘要： A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). Availability of charged portable electrical energy storage devices available at a collection, charging and distribution machine are communicated to or acquired by a mobile device of a user or a user's vehicle. Once the mobile device of a user or a user's vehicle comes within close proximity of the collection, charging and distribution machine or within a particular area surrounding the collection, charging and distribution machine, the collection, charging and distribution machine or a collection, charging and distribution machine management system communicates an alert (e.g., over a cellular network, short range wireless signal or wireless fidelity (Wi-Fi) network) to the mobile device or vehicle indicating how many portable electrical energy storage devices are available at the distribution machine.
