  • Patent number: 10377237
    Abstract: An apparatus and a method are provided for controlling a low DC-DC converter (LDC) in an electric vehicle by prioritizing respective controllers, connecting the controllers in series in ascending order according to priority, and determining a command voltage of the LDC on the basis of output voltages of the respective controllers. Accordingly, even when a controller with a highest priority is operating, controllers of lower priority continue operating. Thus, electrical load performance degradation caused by instantaneous overcurrent generated in state transitions is prevented.

  • Patent number: 10236134
    Abstract: A battery thermal shield is used with a battery to reduce peak temperature exposure caused by a short of a battery from physical damage to the battery (e.g., the battery being pierced by a metal object). The thermal shield may be a highly thermal-conductive substance, such as a film, adhesive, gel, and/or other substance, that acts as an efficient heat spreader. Unlike a typical heat sink or heat fins, the thermal shield may have a low profile and be configured to spread a rapid onset of heat at a localized point or area (e.g., a location of an internal short) to a wider area to reduce a peak (maximum) temperature caused by a short of a battery. The thermal shield may be at least partially formed of graphite which may be adhered to the battery.

  • Patent number: 10225440
    Abstract: A system for securely storing and charging a mobile device includes an AC-connectable device, such as a multi-function printer or photocopier, having a charging area and a power source, wherein a mobile device such as a smartphone, a tablet computer, an e-reader or a portable rechargeable battery pack, is charged by placing the mobile device in the charging area and attaching the device to the power source. The charging area allows for the mobile device to be secured to or within the AC-connectable device. The charging area can be configured in many ways, including as a movable locking compartment, a fixed locking compartment or a rotatable locking compartment. The mobile device may also be used to power the AC-connectable device when it is not connected to an AC power source. The system also optionally provides for cleaning, sanitizing or drying of the mobile device while it is in the charging area.

  • Patent number: 10218209
    Abstract: A method, system, and computer program product for selecting a charging mode from among the set of charging modes supported by a charging device for charging a battery of a portable device. The method includes detecting a coupling of a charging device and the portable device. In response to detecting the coupling, a set of charging modes supported by the charging device is determined. The method further includes identifying whether the set of charging modes includes a particular charging mode. In response to identifying the charging device supports the particular charging mode, a first notification is issued to the charging device to trigger the charging device to operate in the particular charging mode. In response to identifying the charging device does not support the particular charging mode, an alternate charging mode is selected from among the set of charging modes.

  • Patent number: 10218195
    Abstract: Disclosed is a switching-type charging circuit including a first switch, a current detection unit, a switching circuit and a control circuit. The current detection unit is connected to the first switch and detects a current flowing through the first switch. The switching circuit is connected to the input end of the switching-type charging circuit through the first switch to receive an input voltage, and correspondingly outputs an output voltage to a battery through an inductor. When the input voltage of the switching-type charging circuit is cut off, an inverse current flowing to the first switch through the switching circuit is generated by the battery, and the control circuit adjusts the working frequency of the switch circuit to make the inverse current lower and become equal to or less than a quiescent current.
