  • Patent number: 11180046
    Abstract: A method of charging a battery in a vehicle, the method comprising: controlling, by a controller, battery charging from a power source external to the vehicle, charging the battery to a state of charge (SOC), wherein the SOC is based on: cost of electricity, source of electricity, battery health, battery temperature, electrical grid voltage, electrical grid frequency, and/or utility incentives. Generally, the vehicle charges more on good days so it can charge less on bad days, and charges less on bad days so it can charge more on good days.

  • Patent number: 11183918
    Abstract: In an abnormality determination system, when a drive signal is input and no shutdown signal for stopping gate drive of switching elements is input, a signal switching section outputs the drive signal to a bridge circuit. When a shutdown signal is input, the signal switching section stops output of the drive signal and activates a shutdown function of an inverter. An abnormality determination section determines an abnormality in the shutdown function. When a power source relay is opened, a control unit drives the bridge circuit to start a discharge process of discharging electric charge from a smoothing capacitor, and activates the shutdown function during execution of the discharge process. When it is determined that a directly or indirectly detected voltage of the smoothing capacitor has dropped during operation of the shutdown function, the abnormality determination section determines that the shutdown function is abnormal.

By cycling so that only a few of the vehicles are charging at a time, the demand on the circuits is kept below a predetermined limit. In cases where a load shedding event is in progress, the limit can be further reduced. In cases where the cost of electricity is varying dynamically, the system considers a driver's explicit charging requirements (if any) and preferences for opportunistic charging when the price of electricity is not too high.

  • Patent number: 11121565
    Abstract: Combination fuel cell stack and electrochemical battery system provides stable and redundant electrical power to one or more traction motors. The electrochemical battery packs comprise modules that are switched between a low-voltage parallel configuration connecting to the fuel cell stack and a high-voltage series configuration connecting to the traction motors, thereby harvesting low-voltage energy from the fuel cells and deploying that energy as high-voltage power to the motor. The plurality of electrochemical battery packs can be switched such that at least one is always connected to the traction motor for continuity of power.

  • Patent number: 11117480
    Abstract: When DC charging is completed, an ECU of a vehicle performs first diagnosis processing for diagnosing whether or not charge relays have stuck with an SMR being closed. In the first diagnosis processing, whether or not the charge relays have stuck is diagnosed based on an open/close command to the charge relays and a voltage applied to a charge port. When both of the charge relays are determined as having stuck in the first diagnosis processing, the ECU performs second diagnosis processing on the assumption that a DC power feed facility falls under a specific DC power feed facility. In the second diagnosis processing, whether or not the charge relays have stuck is diagnosed based on the open/close command to the charge relays, the voltage applied to the charge port (a first voltage), and a voltage (a second voltage) between a first power line and a second power line.

  • Patent number: 11117487
    Abstract: An electric vehicle charge controller and charging method for controlling a charging rate for a battery of an electric vehicle is presented. The battery receives charge via a node connected to a power distribution source. The charge controller receiving a nodal voltage measurement for voltage at the node, receiving a value of electric power at the node, and determining a change in the electric power value based on a previous electric power value. When the change in electric power is greater than a load change threshold, the charge controller determines an estimate of voltage-to-load sensitivity. The charge controller determines the charging rate of the electric vehicle based on the nodal voltage, the determined voltage-to-load sensitivity, and a state of charge of the at least one battery, and controls the charging rate for the at least one battery in accordance with the determined charging rate.
