Abstract: A method for charging a secondary battery utilizing a deposition-dissolution reaction of metallic lithium as a reaction of a negative electrode has a multi-stage charging step. The method comprises at least: a first charging step in which the secondary battery is charged at a first current density to deposit metallic lithium on a surface on the solid electrolyte layer side of the negative electrode current collector to form a deposited Li layer; and a second charging step in which the secondary battery is charged at a second current density greater than the first current density after the first charging step to increase a thickness of the deposited Li layer, wherein the first charging step includes performing pausing at least once or discharging at least once, in which the secondary battery is charged at the first current density so that an SOC does not exceed 4.5%.

Abstract: A vehicle armrest includes an opening/closing body, a switch knob and an operation transmission mechanism. The opening/closing body opens and closes an upper side of a storage section. The switch knob is configured to open the opening/closing body. The operation transmission mechanism opens the opening/closing body in response to an operation of the switch knob. The opening/closing body includes an inner base portion and an outer lid portion. The outer lid portion is movably connected to the base portion to move forward and rearward in a front-rear direction. The switch knob is disposed in a fixed position in a main box body farther forward than the front end of the opening/closing body when the lid portion has been moved to the forwardmost position.

Abstract: A method for subscribing a mobile equipment to a service hosted on at least one data processing peripheral server in a Mobile Edge Computing architecture network includes sending a message for registration from the mobile equipment to a central server of the network and establishing, by the mobile equipment, a communication session with a first data processing peripheral server. Prior to establishing the communication session with the first data processing peripheral server, upon receiving the message for registration, the central server selects the first data processing peripheral server corresponding to a location of the mobile equipment.

Abstract: A vehicle has a motor that drives the vehicle, a battery that allows supplying an electric power to the motor, and a power conversion device disposed between the motor and the battery. An execution command of ripple charging and discharging that alternately charges and discharges multiple times with the battery is output to the power conversion device when a temperature of the battery is lower than a predetermined threshold temperature, and the flow rate of the heating medium is controlled such that the flow rate of the heating medium is reduced compared with a case where the temperature of the battery is lower than the temperature of the heating medium when the temperature of the battery is higher than the temperature of the heating medium that exchanges heat with the battery while the ripple charging and discharging is executed.

Abstract: A communication control device is configured to select a communication frequency band for communicating between a vehicle and an external base station when starting communication between the vehicle and the external base station. In selecting the communication frequency band, the communication control device measures or determines the amount of electromagnetic noise in each frequency band inside the cockpit module. Then, the communication control device changes the communication frequency band based on the amount of electromagnetic noise, and communicates with the external base station using the changed communication frequency band.

Abstract: A secondary battery is configured by stacking a plurality of battery cells containing a lithium metal or a lithium-containing alloy as a negative electrode active material on a negative electrode layer. The battery cell has a positive electrode tab connected to the positive electrode collector and exposed to the outside, and a negative electrode tab connected to the negative electrode current collector and exposed to the outside. The positive electrode tab and the negative electrode tab are provided on opposite sides of the center line in the thickness direction of the battery cell, and the positive electrode tab and the negative electrode tab of the adjacent battery cells are arranged and connected so as to face each other.

Abstract: A vehicle control method causes a controller to execute: processing of determining whether or not a first other vehicle traveling on a second lane, the second lane merging with a first lane on which an own vehicle travels in front of the own vehicle, is traveling diagonally in front of the own vehicle; and processing of, when determining that the first other vehicle is traveling diagonally in front of the own vehicle, controlling vehicle speed of the own vehicle in such a way that a front-rear direction distance from a rear-end position of the first other vehicle to a front-end position of the own vehicle in a front-rear direction of the first lane is shorter than a first target inter-vehicle distance in vehicle speed control to maintain an inter-vehicle distance to a preceding vehicle traveling in front of the own vehicle on the first lane.
