In accordance with at least one aspect of the present disclosure, there is provided a method for controlling power in an aircraft. The method includes, monitoring an electric energy storage module electrically connected to an electrical bus for an exceedance of a first current limit and monitoring a generator module connected to the electrical bus for an exceedance of a second current limit. If the current limit of either of the electric energy storage module or the generator module is exceeded by a predetermined exceedance amount, the method includes reducing a power consumption for an electric machine by a predetermined bias until the exceedance of the electrical energy storage and the exceedance of the generator module are both less than or equal to zero.

One embodiment relates to a hybrid vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, a rechargeable power source, and a PTO. The hybrid vehicle drive system can include a control system for reducing or eliminating regenerative braking during a traction control or anti-lock braking event.

A wireless power feeding control apparatus for a vehicle includes a positioning unit and an examination unit. The vehicle is provided with a power receiving coil that wirelessly receives electrical power from a power transmitting coil of a power transmission facility, a parking lock mechanism, and a parking lock sensor that outputs an electrical signal corresponding to a locked state of a wheel established by the parking lock mechanism. The positioning unit positions the power transmitting coil or assists in positioning the power transmitting coil on the basis of a quantity of electricity generated by the power receiving coil receiving a magnetic field from the power transmitting coil subjected to weak excitation weaker than excitation during electrical power transmission. The examination unit checks the locked state of the wheel after the weak excitation is stopped and before the electrical power transmission is started.

The apparatus also includes a first controller configured to control the first voltage converter to convert the second voltage into the first charging voltage and to provide the first charging voltage to the first energy storage device during a charging mode of operation and communicate with a second controller located remotely from the power electronic energy conversion system to cause a second charging voltage to be provided to the first energy storage device during the charging mode of operation to rapidly charge the first energy storage device.

A method for operating at least two pulse-width-modulated inverters connected to a direct-current supply network. The pulse-width-modulated inverters are each actuated via an actuation signal and operated in an operating point. A phase difference is generated between the actuation signals of the at least two pulse-width-modulated inverters by adapting the actuation signal of at least one of the pulse-width-modulated inverters as a function of operating point information describing the operating points of the pulse-width-modulated inverters.

The invention includes a Microprocessor Control Center for controlling an Electric Vehicle Charging Station, and methods thereof, which include a load center for aggregating a charging load from a renewable energy source, a battery stored energy source, and electricity taken directly from the transmission grid when the battery storage depleted. The objective of the system is to maximize the use of the renewable energy source which is used directly and at first priority. The use of an energy storage system prevents local brown-outs which can occur when large amounts of electricity is quickly removed from the grid. The energy storage system is recharged from the grid off-peak when rates and house-hold usage are lowest. In a preferred embodiment, the renewable source is solar power, in other embodiments the renewable source can be wind, tidal and biomass. The solar panels are located on the weather canopy roof at petroleum retail fueling sites.

A power supply system with a large number of battery modules, wherein each battery module has a first electrical connection and a second electrical connection, via which the battery modules are connected in series in an interconnection branch of the power supply system. Each battery module also has an accumulator which can be connected via a bridge circuit of the battery module to the first electrical connection and the second electrical connection, and to a charging path via which the power supply system can be charged, and to a discharging path via which the power supply system can deliver electrical power to a connected consumer. The power supply system has a switching component to which the charging path, the discharging path and the interconnection branch are connected, and wherein the switching component can connect the charging path and/or the discharging path electrically conductively to the interconnection branch.

A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.
