In a case in which an excess sensor which is a sensor in which the value for comparison exceeds the threshold value is present in one of the consecutive comparison processes, the detector determines that a foreign substance is present when the number of times of excess, which is the number of times at which the value for comparison exceeds the threshold value in the excess sensor reaches the first number of times. In a case in which the excess sensors of which the number is a first count that is more than one are present in one of the consecutive comparison processes, the detector determines that the foreign substance is present when the number of times of excess in each of the excess sensors of which the number is the first count reaches the second number of times, which is less than the first number of times.

A battery management system and method for performing a battery state and, optionally, health parameter observation is disclosed, in particular, cell state-of-charge (SOC) observation, with two redundant, independent and dissimilar lanes. Specifically, a SOC determination in a first one of the lanes is based on Coulomb Counting. The other lane employs a different algorithm than Coulomb Counting. In some embodiments, a battery health observation is further performed independently by the two lanes, wherein the first lane employs an aging model and the other lane a different (dissimilar) algorithm. On the basis of state and health observation, state (state of function) of the battery system can be predicted to determine a range of flight in accordance with a predetermined flight profile.

A device to inspect a pipeline includes a device housing, a plurality of motors, a plurality of wheels, an inertial measurement unit, and a controller. The plurality of motors is coupled to the device housing. The plurality of wheels extends from the device housing. Each wheel is rotatably coupled to a respective motor. The inertial measurement unit is configured to provide a signal corresponding to an orientation of the device housing relative to the pipeline. The controller is configured to independently control operation of each motor of the plurality of motors based on the signal provided by the inertial measurement unit to maintain the device housing within a desired orientation range relative to the pipeline. Because the controller can independently control each motor of the device, the device can advance along a pipeline with minimal human intervention.

An electric vehicle comprises an electric motor for generating driving power for moving a vehicle body of the electric vehicle; a battery unit for supplying electric power to the electric motor; a charging connector connected to an outside electric power supply for supplying the electric power to be charged; a main controller for controlling switching between a first connection state in which the battery unit is connected to the electric motor and a second connection state in which the battery unit is connected to the charging connector; and a relay for opening and closing a power supply path from the low-voltage battery to the main controller; wherein a relay opens the power supply path to cut off electric power supply to the main controller for a specified time, when the relay switches one of the first connection state and the second connection state to the other connection state.

A method for detecting an imminent overheating of at least one battery cell of a battery, preferably for a motor vehicle. The imminent overheating is detected as a function of at least one determined first variable relating to the at least one battery cell. A temperature gradient over time of a temperature sensed in a predetermined proximity to the at least one battery cell and/or a voltage of the at least one battery cell is determined as the at least one first variable.

There is provided a charging device for a vehicle, which carries out timer charging in which the charging device, is set in a standby state without charging until charging start time comes when the charging start time is set. The charging device includes a charger that charges an electrical storage device of the vehicle with electric power supplied from a device outside the vehicle, a cable lock mechanism (260) that locks a charging cable in a state where the charging cable is connected to an inlet, and an electronic control unit (170) that determines whether to carry out timer charging or carry out instant charging without carrying out the timer charging on the basis of a state of a switch associated with operation of the cable lock mechanism (260).

Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.

In a high-speed measurement mode, a high-voltage measurement mode (V0 measurement) is omitted and only a negative-pole side ground fault resistor voltage measurement mode (VC1n measurement) and a positive-pole side ground fault resistor voltage measurement mode (VC1p measurement) are performed. In the negative-pole side ground fault resistor voltage measurement mode (VC1n measurement) and the positive-pole side ground fault resistor voltage measurement mode (VC1p measurement), the charging time for the flying capacitor is set to a second predetermined time period that is shorter than a first predetermined time period, which is different from basic operations in a normal measurement mode.
