A shared charging cabinet and an ejecting control method thereof are provided. The method includes the steps of: a comprehensive ranking of shared power supplies (200) currently contained in the shared charging cabinet (100) is performed according to lending times and remaining power of shared power supplies; when the shared charging cabinet (100) receives a lending instruction, one of the shared power supplies (200) is controlled to be ejected according to the comprehensive ranking in response to the lending instruction. Therefore, the ejecting order of the shared power supplies (200) in this application is determined according to the lending times and the remaining power of the shared power supplies (200), so that the ejecting times of the shared power supplies (200) in the shared charging cabinet (100) is balanced, and the service life of the shared power supplies (200) can be further balanced.

An user-interactive charging paradigm is presented that tailors the device charging to the user's real-time needs. The core of approach is a relaxation-aware charging algorithm that maximizes the charged capacity within the user's available time and slows down the battery's capacity fading. The approach also integrates relaxation-aware charging algorithm existing fast charging algorithms via a user-interactive interface, allowing users to choose a charging method based on their real-time needs. The relaxation-aware charging algorithm is shown to slow down the battery fading by over 36% on average, and up to 60% in extreme cases, when compared with existing fast charging solutions. Such fading slowdown translates to, for instance, an up to 2-hour extension of the LTE time for a Nexus 5X phone after 2-year usage, revealed by a trace-driven analysis based on 976 charging cases collected from 7 users over 3 months.

Provided is a battery unit including: a power supply; a detector configured to detect an output voltage of the power supply; a connecting configured to be connectable with a load for atomizing an aerosol source or heating a flavor source; and a controller capable of executing a power supply mode in which electric power is supplied to the load from the power supply. The controller executes a specific control different from the supply of electric power to the load based on am amount of change in the output voltage per a predetermined time period in the power supply mode.

Power management techniques are disclosed. For instance, an apparatus may include a bidirectional voltage converter circuit, and a control module that selectively operates the bidirectional voltage converter circuit in a charging mode and a delivery mode. The charging mode converts a voltage provided by an interface (e.g., a USB interface) into a charging voltage employed by an energy storage module (e.g., a rechargeable battery). Conversely, the delivery mode converts a voltage provided by the energy storage module into a voltage employed by the interface. Other embodiments are described and claimed.

A method is provided for carrying out a charging process of a vehicle-external charging apparatus (1) for charging a vehicle (2), in particular an electric or hybrid vehicle. The method includes using a current measuring instrument (3) of the charging apparatus (1) to measure a charging current. The method then includes closing a first contactor (4) of the charging apparatus (1) and a second contactor (5) of the vehicle (2) for a time period that is measured by the current measuring instrument (3). A charging apparatus (1) for performing the method also is provided.

An electronic control unit is configured to i) turn off a charging relay when a charger is disconnected from an external power source while external charging is in progress which is started when the charger is connected to the external power source and the charging relay is turned on while a system is off and in which a battery is charged with electric power from the external power source by the charger, and ii) set the period from the disconnection of the charger from the external power source to the turn-off of the charging relay to be longer when preliminary air conditioning is in progress than when preliminary air conditioning is not in progress.

An interchangeable shaft assembly for a surgical instrument that includes first and second drive systems. The interchangeable shaft assembly is configured for removable attachment to a housing of the surgical instrument. Various embodiments include a latch system that enables the interchangeable shaft assembly to be detached from the housing when the first drive system is unactuated but prevents the interchangeable shaft assembly from being detached from the housing when the first drive system is in an actuated position.

The battery cellar includes a storage cabinet that stores a plurality of used batteries, a power converter (an AC/DC converter and a DC/DC converter) electrically connected between the plurality of used batteries stored in the storage cabinet and a power system, and a server that controls the power converter to charge or discharge the plurality of batteries in response to a demand response request from the power system. The server selects, from the plurality of used batteries, a first battery, the degradation degree of which has reached a reference value, and a second battery, the degradation degree of which does not reach the reference value but is predicted to reach the reference value within a predetermined period, as replacement target batteries.
