System and method for management of heterogeneous battery modules
A battery management system and method that allows a battery bank to be composed of battery modules that can be heterogeneous with respect to each other. A battery bank composed of modules that support the battery management system allows for any subset of modules to be easily replaced with modules of different electrochemical characteristics. Each of the modules may also have a controller that manages cells of the module. The bank level controller and module level controller may operate to virtualize the hardware under their management to reduce or eliminate the heterogeneous features of the underlying cells and modules.
Systems and methods for individual control of a plurality of battery cells
A battery control system includes a plurality of battery cells that are separately controllable as units of individual cells or groups of cells. Each controllable unit may be switchably activated or deactivated in the overall battery circuit, and one or more conditions of each controllable unit may be individually measured. Various techniques are disclosed for operating the battery control system to optimize or improve system performance and longevity.
System for flight plan generation of an electric vertical takeoff and landing (eVTOL) aircraft and a method for its use
Aspects relate to a system for flight plan generation of an electric vertical takeoff and landing (eVTOL) aircraft. An exemplary system for flight plan generation includes a flight controller mounted on an eVTOL aircraft. The flight controller may be configured to receive a plurality of flight plan data and generate a flight plan for the aircraft as a function of the plurality of flight plan data.

Electrified powertrain with centralized power distribution strategy and decentralized inverters
A method for distributing electrical power to electric motors in an electric powertrain, in which the electric motors are electrically connected to a shared power supply, includes receiving input signals via a supervisory controller. The input signals include a total torque request of the electric powertrain and electrical limits of the power supply. The method includes determining an open-loop torque command for each respective motor in response to the input signals. In response to the total torque request and the power supply limits, the controller also determines maximum and minimum power limits of motor, with the maximum and minimum power limits including a calibrated power reserve for executing a predetermined torque operation. The method includes transmitting the open-loop torque command and the power limits to a respective motor control processor of each motor to thereby control the torque operation.
Electric vehicle (EV) charge unit reservations
A computer implemented method for managing charge availability of a charge unit (CU) to obtain charge for a battery of an electric vehicle (EV) is provided. The CU includes a computer for processing at least part of the method and for communicating with a server over a network. The method includes receiving, by the server, status information from the computer of the CU. The method includes sending to the computer of the CU instructions to make a reservation for the CU. The reservation is for a user account that has requested a desire to charge the battery of the electric vehicle of the user at the CU or another CU. The method includes sending, by the server, a confirmation for the reservation to the user account. The confirmation is viewable via a device having access to the server via the user account. The method includes sending, by the server, a data regarding a time of availability of the CU to the user account for the reservation. The computer of the CU is configured to display a visual indicator regarding the reservation of the CU.

Electric vehicle
An electric vehicle includes: a rotary electric machine configured to generate a driving force for driving driving wheels; a driving battery storing power to drive the rotary electric machine; a converter connected to the driving battery; an auxiliary battery connected to the driving battery via the converter; and a cooling box connected to the auxiliary battery. When the driving battery has an SOC reduced to be smaller than a prescribed threshold value, the converter is stopped and power remaining in the auxiliary battery is used to drive the cooling box.

Hybrid-type engine generator output controller
In an output control of a hybrid-type engine generator equipped with a load output demand detecting unit, a load output demand increase/decrease determination unit and an output control unit, a configuration is adopted whereby load output demand from (output required by) the load is detected, increase/decrease of the detected load output demand is determined, discharge power from the battery is added to generated power output of the engine generator unit when detected load output demand is determined to be increasing, and output of the engine generator unit is controlled so as to use some generated power output of the engine generator unit as charge power of the battery when detected load output demand is determined to be decreasing.
