Control device for controlling a switch in a charging line disposed between a first power line and a second power line in a power distribution architecture. The control device includes a current level input for receiving a current measurement of the current conducted through the charging line, a voltage level input for receiving a voltage measurement of the voltage applied on the charging line. A monitor monitors the relationship between the current and voltage measurements and generates a control signal for controlling the switch in response to a coherent change in the current and voltage measurements exceeding a threshold. A control signal is not generated when a change in one of the current and voltage measurements exceeding a threshold is not associated with a coherent change in the other of the current and voltage measurements.

Various embodiments are described that relate to charging a battery set. The battery set can comprise a first battery and a second battery. The batteries can be alternately charged so they are balanced. In one example, when the first battery is charged, then the second battery is not charged and vice versa. The alternation of charging can be managed based on different criteria, such as timing or charge level.

A vehicle power system includes a coil that, in a first operational mode, receives power wirelessly from an external source, a first battery connected to the coil to receive power transferred from the coil while the coil is in the first operational mode, a second battery that receives power from the first battery, and a switch that switches the coil between the first operational mode and a second operational mode in which the coil receives power from the second battery and wirelessly transfers power from the second battery to an electrical load in the vehicle.

A power supply control device controls power supply by switching on or off a first semiconductor switch and a second semiconductor switch that are arranged on a current path. A first diode and a second diode are connected between a drain and a source of the first semiconductor switch and the second semiconductor switch, respectively. Cathodes of the first diode and the second diode are arranged downstream and upstream of the respective anode on the current path. If current flows through the current path even though a microcomputer has given an instruction to switch the first semiconductor switch and the second semiconductor switch off, a first drive circuit switches the first semiconductor switch on.

A jump starting device having USB. For example, a handheld jump starting device having USB for boosting or charging a depleted or discharged battery. The handheld jump starting device, for example, can include a rechargeable lithium ion battery pack and a microcontroller. The lithium ion battery can be coupled to a power output port of the device through a power switch circuit actuated by the microcontroller.

A method for controlling an energy terminal, comprises determining a metric indicating a future availability of an energy resource at an energy terminal based on usage data associated to use of the energy resource by the energy terminal, generating control data to control the distribution of the energy resource between the energy terminal and an energy infrastructure based on the metric, and communicating the control data to the energy terminal.

A mobile device mounting system includes a device case and a mount. The device case includes: an insert including a rectangular bore and defining a set of undercut sections about the rectangular bore; and a first set of magnetic elements arranged in a first pattern about the rectangular bore. The mount includes: a body; a polygonal boss extending from the body and configured to insert into the rectangular bore; a set of locking jaws arranged on the polygonal boss configured to transiently mate with the set of undercut sections to constrain the polygonal boss within the rectangular bore; and a second set of magnetic elements arranged in a second pattern about the polygonal boss and configured to transiently couple to the first set of magnetic elements to transiently retain the mount against the device case and to drive the set of locking jaws toward the set of undercut sections.

The disclosure is directed to a system and method for providing supplemental power to start one or more cranking motors. The supplemental starting system includes a starting-signal isolator configured to connect to one or more electrical starting-signal wires providing starting signal to one or more cranking motors, a resetting relay electrically connecting to the starting-signal isolator, a programmable logic controller (PLC) electrically connecting to the resetting relay, a supplemental battery relay electrically connecting to the starting-signal isolator and the PLC, a supplemental battery electrically connecting to the supplemental battery relay, and a positive output-terminal electrically connecting to the supplemental battery relay. When an output of the starting-signal isolator is higher than a threshold voltage, the resetting relay and the supplemental battery relay are configured to be in a close state, so that the supplemental starting system is configured to provide electricity to one of the one or more cranking motors.
