  • Patent number: 9020674
    Abstract: A regenerative braking system for a vehicle utilizing diversion of energy for efficient use or maintaining consistent vehicle performance. The regenerative braking system includes a generator for producing regenerative energy during slowing and includes switches connected to a battery and a plurality of devices. A processor is connected with the battery and the switches for controlling the configuration of the switches based on a characteristic of the battery. If the battery has a state of charge exceeding a predetermined threshold, the processor controls the switches to route the regenerative energy to the other devices. The processor also controls the switches to provide regenerative energy to specific devices where it may most desirably be utilized. Heating and cooling units of the vehicle may be alternatively or simultaneously connected to receive the regenerative energy for providing consistent vehicle slowing performance when the battery state of charge exceeds the predetermined threshold.

  • Patent number: 8942875
    Abstract: A method and a system for changing the segments of an SOC indicator of a vehicle at non-linear rates or for changing the number of the segments in an on state more slowly when the SOC is high or low as opposed to when the SOC is in the middle range. The system can be implemented with a vehicle including a battery, a sensor, a processor, a controller and a display. The method may include determining a display SOC based on the SOC of the vehicle, providing, by a display, three sets of lights including a low-SOC set, a middle-SOC set, and a high-SOC set, each light is illuminated or de-illuminated based on whether the display SOC has changed by an amount greater than the light's assigned power increment or decrement, where the middle-SOC power increments and decrements are less than the low-SOC or high-SOC power increments and decrements.

  • Patent number: 8892300
    Abstract: A method and a system for changing the power consumption value available for an HVAC unit of a vehicle when an available battery power for batteries of the vehicle is low. A method and a system for non-linearly changing the power consumption value available for the HVAC unit when the available battery power decreases to a power value less than a low power value. The system can be a vehicle including batteries, an HVAC unit, an ECU and a memory. The method may include setting an HVAC power consumption value to a relatively constant power value when the available battery power is greater than a low power value and decreasing the HVAC power consumption value by a non-linear rate of power reduction when the available battery power decreases to a power value less than the low power value.

  • Patent number: 8820446
    Abstract: A vehicle is equipped with a battery, an electric motor configured so as to generate the driving force of the vehicle by use of the electric power stored in the battery, a charger configured so as to supply the electric power outputted from the power supply outside of the vehicle to the battery, and an ECU configured so as to control the state of charge of the battery when the battery is charged. The ECU calculates an index value indicating the state of charge of the battery, and sets the control range thereof. The ECU raises the upper limit of the index value so that the possible travel distance of the vehicle becomes not less than the target distance when predetermined conditions on degradation of the battery are satisfied.

  • Patent number: 8712619
    Abstract: A vehicle is equipped with a battery configured so as to be rechargeable, a motor generator configured so as to generate the driving force of the vehicle by use of electric power stored in the battery, a switch configured so as to switch between generation of a command for extending the use period of the battery and stop of generation of the command, and an ECU for controlling the state of charge of the battery. The ECU sets the control range of SOC of the battery. When the switch stops generation of the command, the ECU sets the control range to a first range. Meanwhile, when a command is generated by the switch, the ECU sets the control range to a second range narrower than the first range.

  • Publication number: 20140097676
    Abstract: A charging control unit sets a fully charged state of a power storage device so as to have a margin for a fully charged capacity of the power storage device. The charging control unit sets the fully charged state to be variable in accordance with a degree of deterioration of the power storage device such that the margin becomes smaller as the degree of deterioration of the power storage device is larger. A traveling control unit switches between first control and second control in accordance with a degree of decrease of the margin when regenerative electric power exceeds a charging power upper limit value, the first control being control for regenerating, to the power storage device, an excess of the regenerative electric power relative to the charging power upper limit value, the second control being control for consuming the excess of the regenerative electric power using an auxiliary load.

  • Patent number: 8598734
    Abstract: Converters are connected in parallel with each other to a pair of electric power lines. When required electric power required by a drive force generation unit is not more than a threshold value, a converter ECU causes a voltage converting operation of one of the converters that is associated with a power storage device of a higher output voltage to perform voltage converting operation, and causes the voltage converting operation of the other converter to be stopped, based on output voltages of the power storage devices detected by output voltage detection units. The first power storage device and the second power storage device are configured so that one of the power storage devices has a higher power supply voltage by a predetermined value than the power supply voltage of the other power storage device. The predetermined value is defined based on errors which may be included in detected values of the output voltage detection units.

  • Publication number: 20130275023
    Abstract: A variable power drive mode system for a vehicle. The system includes a pedal, a processor, an engine or other vehicle power source for moving the vehicle and a battery. The processor of the vehicle determines, either automatically or based upon user input, a desired drive mode for the vehicle. A memory connected with the processor stores different data corresponding to the different drive modes determinable by the processor for the vehicle. The processor uses the different data stored in memory in combination with a position of the pedal to control the engine or other vehicle power source to generate power in accordance with the determined drive mode. Certain drive modes may provide for more aggressive driving profiles at the expense of fuel efficiency or fuel consumption when compared to other drive modes.
