Vehicles that are capable of connecting to the AC grid are described that comprise a prime mover and at least one motor generator. In one embodiment, a vehicle may be constructed as a plug-in hybrid system and using the powertrain under controller instruction to either place power on an AC power line (to service AC grids) or to draw power from the AC power line to add electrical energy to the batteries on the vehicle. In some aspects, vehicles may test whether the power needed to service the AC power line may be satisfied by the on-vehicle batteries or, if not, whether and how much power to extract from the prime mover. In some aspects, vehicles may have a thermal management system on board to dynamically supply desired heat dissipation for the powertrain, if the powertrain is using the prime mover to supply power to the AC grid.

Methods and systems are provided for controlling a high power output direct current to alternating current converter for a vehicle. In one example, a method may include at a vehicle-on event, automatically operating the converter in a first power output mode, and transitioning to a different mode of operation in response to a transition request being received at a controller of the vehicle. In this way, the different mode of operation may be subject to confirmation via an operator of the vehicle, which may improve operational performance of the direct current to alternating current converter.

A power distribution includes first and second inputs, first and second outputs, and a third output configured to connect to a low-voltage vehicle power supply, a high-voltage distributor is connected to the first input and forms the connection between the energy storage and further components of the power distribution. A controller monitors at least the high-voltage distributor and can control components of the power distribution. At least one inverter is arranged in the current path between the high-voltage distributor and at least one of the contacts for the first output, the second output or the second input, a first converter is arranged between the high-voltage distributor and the third output and converts a DC voltage provided by the high-voltage distributor to a lower DC voltage.

Apparatuses, systems, and methods for transferring electrical power between an electrical power system of a vehicle and another device. In an illustrative embodiment, an apparatus includes a wireless transfer unit electrically coupled with a high voltage system of a vehicle and configured to enable wireless bidirectional power exchange between the high voltage system and an auxiliary device. The high voltage system is operable to power a drivetrain of the vehicle and the auxiliary device is separate from the vehicle and configured to at least one of provide electric power to and receive power from the high voltage system. A transfer control unit is configured to communicate with the wireless transfer unit and control at least one parameter specifying a transfer of electrical power between the high voltage system and the auxiliary device.

The present disclosure provides a method of providing guidance for use of electric power of an electric vehicle capable of limiting use of electric power in a vehicle-to-load (V2L) mode or providing various pieces of information on use of the electric power. The method includes receiving information on a set travel route to an electric vehicle charging station in the V2L mode, calculating battery energy requirements necessary for the vehicle to move from the current location to a charging station along the travel route, calculating available amount of energy in the V2L mode based on the battery energy requirements and the current amount of energy of a battery, calculating an available usage time of an electronic product based on electric power consumption per unit time of the electronic product and the available amount of energy, and displaying the available usage time of the electronic product through an information-providing device.

A portable beach cooler is capable of reducing the temperature of stored items. A main cooling body opens to reveal an ice tray. The ice tray may be connected to a lifting mechanism that allows the ice tray to rise for convenient user access to ice. The lid of the cooling body may have several cupholders traversing through the lid, providing direct access to ice for contained beverages. A cupholder adapter may support beverages atop the lid or may be inverted atop a beverage contained within the cupholder to provide direct beverage access to ice while simultaneously preventing cold air from escaping. A set of tracked wheels is connected to a motorized frame capable of supporting the cooling body. The apparatus may further be equipped with cameras to allow for automatic maneuvering of the motorized frame behind a user, as well as a variety of other electronic ports and devices.

A vehicle includes a battery, an electric power acquirer, a relay, a power supply unit, and a controller. The controller is able to switch a mode of electric power transmission to a direct transmission mode on the first condition that electric power is transmitted from the electric power acquirer to the battery and the power supply unit is in continuous operation or starts up. The direct transmission mode includes that the relay is in a disconnected state and electric power is transmitted from the electric power acquirer to the power supply unit.

The information processing device includes a processor configured to control setting and cancellation of a power supply mode in which the power supply device operates, for a vehicle including the power supply device that supplies electric power to the outside. The processor outputs information requesting an input of authentication information when a canceling request of the power supply mode that is set is acquired.

A system, apparatus, and method may operatively couple to an integrated generator that supplies power to a component of a mobile machine that intermittently demands power during operation of the mobile machine and to a charging station. On condition that the component in the mobile machine does not need power, power may be supplied to the charging station. On condition that an electric mobile machine is connected to the charging station, power from the charging station may be supplied to the electric mobile machine. Otherwise, power may be supplied to the charging station in an energy accumulator to store the power.

A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, a charging controller, and a first notification processor. The first relay connects the battery to a power supply line or disconnects the battery from the power supply line. The charging controller switches, on a request for charging of the battery with the first relay in a connected state, the first relay to a disconnected state, brings the second relay to a connected state, and switches the first relay to a connected state to start the charging of the battery. The first notification processor gives, on the request for the charging of the battery, a user a notification of temporary shutdown of the power supply unit at a start of the charging of the battery.
