A controller, a system including such a controller, and a method for controlling or managing discharge or charge of a plurality of battery packs are provided. The controller includes one or more processor and at least one tangible, non-transitory machine readable medium encoded with one or more programs configured to perform steps to determine a respective power discharge or charge for each battery packs based on characteristic data of each battery pack, a power demand, and the first weighting factor (a) and the second weighting factor (b) for power assignment based on voltage and state of charge of each battery pack. The controller provides signals with instructions to the plurality of battery packs and/or the one or more power converters for discharging power from or charging power to the plurality of battery packs.

An agent is an information processing apparatus that puts in a bid to allow a vehicle to conduct transaction of power reception/provision through a transaction market server. In the event of nonfulfillment of transaction which means that the vehicle does not conduct transaction of power reception/provision, the transaction market server performs penalty processing for imposing a penalty on a user of the vehicle. The agent includes a bid processing unit and an indicator value calculator. The bid processing unit is configured to put in a bid to the transaction market server. The indicator value calculator calculates an indicator value that represents an extent of the penalty imposed on the user in the penalty processing. When the indicator value reaches a threshold value, the bid processing unit suspends a bid.

An in-vehicle battery management device includes a controller configured or programmed to control a charge/discharge device such that the charge/discharge device performs charge or discharge on an in-vehicle battery of an electric vehicle in a predetermined processing condition, the in-vehicle battery being connected to the charge/discharge device. The controller includes a calculator configured or programmed to calculate a degree of deterioration progress of the in-vehicle battery based on charge/discharge information in the charge or discharge; and a communicator configured or programmed to notify a predetermined notification target of the calculated degree of deterioration progress.

Systems and methods for charging electric vehicles that define a charging schedule for an electric vehicle based on one or more charging preferences of an operator of the vehicle and based on at least one current value of a dynamic attribute of an electric charge provider. Such systems and methods may include a graphical user interface adapted to display a unitary vehicle charge indicator element having (i) a first portion indicative of an amount of charge residing in a battery of the electric vehicle, (ii) a second portion indicative of an uncharged capacity of the battery of the electric vehicle, and (iii) a third portion comprising a slider by which an amount of charge may be specified.

The charging/discharging time of electric vehicle is shortened. The charging/discharging management system includes: a first acquisition controller configured to acquire vehicle information including vehicle capabilities regarding charging/discharging capabilities of multiple electric vehicles; a second acquisition controller configured to acquire device information including device capabilities regarding charging/discharging capabilities of multiple charging/discharging devices capable of charging/discharging the electric vehicles; and an assigning controller configured to compare the vehicle capabilities and assign the charging/discharging device having a high device capability among the charging/discharging devices for which device information has been acquired in the second acquisition controller, to the electric vehicle having a high vehicle capability.

Method and system for managing hydrogen fuel in hydrogen fuel cell-powered aircraft is disclosed. The method identifies unused hydrogen fuel in a fuel tank of the aircraft. Determines an amount of the unused hydrogen fuel in the fuel tank of the aircraft. Transfers the amount of the unused hydrogen fuel from the fuel tank of the aircraft into a hydrogen fuel cell of the aircraft and converts the amount of the unused hydrogen fuel into electricity via the hydrogen fuel cell of the aircraft.

A system for charging a battery within an at least partially electric vehicle. The system includes a charging device wherein the charging device configured to electrically connect to the at least partially electric vehicle and charge at least one battery by a predetermined amount. The system also includes a network configured to determine the location of the charging device.
