The second mode is mode in which the width of changes over time in power charged to or discharged from the storage battery is controlled to stay within a prescribed range.

Provided is a system including: a management unit configured to manage a plurality of battery packs connected in parallel, in which the management unit is configured to control the plurality of battery packs to cause the plurality of battery packs to be discharged alternately so that a discharge rate of each of the plurality of battery packs becomes higher than the discharge rate in a case of discharging all of the plurality of battery packs. The plurality of battery packs include a plurality of left-hand side battery packs and a plurality of right-hand side battery packs, and the management unit is configured to manage the plurality of battery packs to cause at least one of the plurality of battery packs in each of the plurality of left-hand side battery packs and the plurality of right-hand side battery packs to be discharged at a time in order.

Provided is a power supply and distribution system, the power supply and distribution system includes at least one non-isolated AC/DC converter unit, an MV DC bus and multiple isolated DC/DC converter units, and the at least one non-isolated AC/DC converter unit is connected between an MV AC grid and the MV DC bus, and is configured to convert an input MV AC voltage to an output MV DC voltage, where the output MV DC voltage is fed into the MV DC bus, the multiple isolated DC/DC converter units are connected to the MV DC bus in parallel via MV class cables, and are configured to convert a voltage level from the MV DC bus to a charging voltage level. The power supply and distribution system can be used for charging the EVs.

A battery apparatus includes: a plurality of battery cells; a battery management system (BMS) for managing the plurality of battery cells; and a connection controller for sequentially connecting the plurality of battery cells to the BMS, and the connection controller connects a corresponding battery cell to the BMS according to a potential of a lower battery cell and a potential of the corresponding battery cell.

A method is for replacing a rechargeable battery that is considered as an unsatisfactory rechargeable battery that needs replacing in an assembled battery in which rechargeable batteries are stacked and restrained in a row and electrically connected in series or in parallel. The method includes removing of finding at least one of the rechargeable batteries to be an unsatisfactory rechargeable battery in the assembled battery and removing the unsatisfactory rechargeable battery, and installing a satisfactory rechargeable battery, which has little deterioration, on at least one end of the row of the rechargeable batteries, in a row direction, in the assembled battery from which the unsatisfactory rechargeable battery has been removed.

A vehicle interior panel assembly includes an in-vehicle support substrate and a stowage tray for a mobile device. The stowage tray includes a reception surface for the mobile device, and one or more sliders configured to attach the stowage tray to the support substrate. The one or more sliders are further configured to tilt the reception surface with respect to a sowed position for the stowage tray in the support substrate. This structure for a stowage tray helps improve within vehicle integration and support more flexible useability.

An electric vehicle charging system includes a power distributing system configured to receive power from a power control system and selectively direct the power to one of a plurality of power dispensers coupled to the power distribution system.

A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

According to at least one embodiment, the present disclosure provides an electro-hydraulic brake comprising: a main brake unit configured to provide braking hydraulic pressure to a plurality of wheel cylinders by driving a motor; an auxiliary brake unit connected to the main brake unit to be filled with high-pressure braking hydraulic pressure, and configured to provide braking hydraulic pressure to the plurality of wheel cylinders when an operation error of the main brake unit occurs; a main battery configured to supply power to the main brake unit and the auxiliary brake unit; and an auxiliary battery configured to supply power to the auxiliary brake unit when the main battery fails, wherein the auxiliary brake unit comprises an auxiliary brake control unit that controls charging and discharging of the auxiliary battery, and a power module that monitors a state of the main battery and transmits the state to the auxiliary brake control unit, and a battery management module that monitors a state of charge (SOC) of the auxiliary battery and transmits the state of charge to the auxiliary brake control unit.
