Abstract: An electric vehicle charging system includes a charging interface positioned on an external surface of the electric vehicle and one or more electrodes positioned on the charging interface. The charging system may also include a heating system positioned on the charging interface. The heating system may be configured to heat at least a portion of the charging interface. The charging system may also include a control system configured to selectively activate the heating system based at least on one or more ambient conditions.

Abstract: A battery monitoring system, comprises a battery state detection circuit that detects battery states of a plurality of battery cells that are connected in series, based on respective cell voltages of the plurality of battery cells, and a control circuit that monitors state of a battery cell, based on each cell voltage of the plurality of battery cells. The control circuit inputs pseudo voltage information to the battery state detection circuit, and thereby diagnoses whether or not the battery state detection circuit is operating normally.
Abstract: A method of controlling a state of charge of a battery in a vehicle includes receiving a request to enter an enhanced charging mode. A target for the state of charge is increased from a normal operating target to at least one enhanced mode target. The state of charge may be controlled to the at least one enhanced mode target during a drive charging cycle and during a park charging cycle.

Abstract: There is herein provided an uninterruptible power supply device with a degradation judgment circuit 4 of a storage battery 2 which can perform an exact judgment, continuing the power supply to a load apparatus 8 stably without giving the excessive burden to the storage battery 2. The storage battery 2 is floatingly charged from a rectifier 1 connected with the power source 10. The device has the control circuit 3 for controlling the output voltage of the rectifier 1 and the degradation judgment circuit 4. The output voltage of the rectifier 1 is lowered to below a steady state by the control circuit 3. As a result, the storage battery 2 discharges with the current Idc restricted rather than rated discharge current. And a part of power supply is supplied to the load 8. The degradation judgment circuit 4 judges the degradation of the storage battery based on the discharge voltage Vdc.
