A system for integrating electric loads into the utility electric grid in a cost-effective, emissions-minimizing way. The system generates and implements a computer-readable series of instructions for one or more of starting and stopping electrical device charging or operation powering of an electrical device's duty cycle. The system includes a planning server including an optimization engine, one or more processors, and a memory device storing instructions thereon that when executed by the one or more processors, causes one or more of the one or more processors to: receive a charge request for charging an electrical device or operation powering of the electrical device's duty cycle, wherein the charge request includes time charge block sorting factors, generate a charging and powering schedule that includes multiple sets of disjointed time charge blocks to start and stop drawing power from a power grid to charge the electrical device or power the electrical device's duty cycle, calculate greenhouse gas emissions created during the scheduled time blocks, wherein each time charge block represents a block of time, a charge price, and a charge emissions value; and sort the time charge blocks in the charging and powering schedule using sorting factors that include price, emissions, solar availability, and combinations therein. Applied to a large number of devices, this system enables integration of devices like smart hot water heaters and electric vehicles into a utility's electric grid with reduced capacity need, avoiding capital expenses and lower operating expenses, while also minimizing carbon emissions and other air pollution.

Presented are control systems for operating rechargeable electrochemical devices, methods for making/using such systems, and vehicles with intelligent battery charging and charging behavior feedback capabilities. A method of operating a rechargeable battery includes an electronic controller receiving battery data from a battery sensing device indicative of a battery state of charge (SOC). Using this battery data, the controller determines a number of low SOC excursions at which the battery SOC is below a predefined low SOC threshold and a number of high SOC excursions at which the battery SOC exceeds a predefined high SOC threshold. The controller then determines if the number of low SOC excursions exceeds a predefined maximum allowable low excursions and/or the number of high SOC excursions exceeds a predefined maximum allowable high excursions. If so, the controller responsively commands a resident subsystem to execute a control operation that mitigates degradation of the rechargeable battery.

A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.

An electrified vehicle includes a controller programmed to implement performance mode control of first and second electric machines and wheel brakes associated with wheels of respective first and second axles to provide a braking force to a first axle while providing torque to the second axle to intentionally spin the tires of the second axle to provide a peelout and associated heating or smoking of the tires to improve traction and provide a visual display of power. The maneuver may be repeated for the first axle by providing torque to the first axle while applying braking force to the second axle. A sequential maneuver that spins tires of the first axle followed by tires of the second axle may be performed by specified manipulation of the brake pedal and accelerator pedal.

A vehicle control system includes one or more processors configured to assign plural vehicles to different groups in one or more vehicle systems for travel along one or more routes. The one or more processors also are configured to determine trip plans for the different groups. The trip plans designate different operational settings of the vehicles in the different groups at different locations along one or more routes during movement of the one or more vehicle systems along the one or more routes. The one or more processors also are configured to modify one or more of the groups to which the vehicles are assigned or the operational settings for the vehicles in one or more of the vehicle systems based on a movement parameter of one or more of the vehicle systems. The trip plans for the different groups of the vehicles are interdependent upon each other.

A battery pack management device capable of reducing power consumption while transmitting and receiving data between a master BMS and a slave BMS by using a wireless communication method. The battery pack management device according to the present disclosure includes: a master BMS including an external communicator, an internal communicator, and a master controller and a slave BMS including a power supply, a state measurement sensor, a slave wireless communicator, and a slave controller.

When the voltage synchronization is determined to be possible, the main controller is configured to transmit a voltage synchronization command to a plurality of auxiliary controllers. The plurality of auxiliary controllers are configured to adjust sensed voltages based on an output voltage of a fuel cell stack when the transmitted voltage synchronization command is received.

A method for controlling a braking torque of a drive system and for braking a vehicle includes in a first state connecting phase connections of a synchronous machine to one another by a changeover apparatus and short circuiting the phase connections such that a first braking torque develops at the synchronous machine. In a second state the phase connections are connected to one another by the changeover apparatus and to a resistance, such that a second braking torque develops at the synchronous machine. The changeover apparatus periodically switches between the first and second states at a switching frequency of 10 Hz or higher to produce a pre-settable braking torque at the synchronous machine, with the changeover between the first state and the second state being controlled by a timing element in an unregulated manner.
