  • Patent number: 8143861
    Abstract: At the time of charging a power storage device from a commercial power supply, electric power from the commercial power supply is applied to a neutral point of each of first and second motor generators. A rotation preventing control unit (222) determines one phase to be subjected to switching control in the first inverter, based on a rotation angle (?1) of the first motor generator. Further, rotation preventing control unit (222) calculates torque generated in the first motor generator, generates a torque control value for canceling out the torque, and outputs the value to a phase voltage operating unit (214) for motor control.

  • Patent number: 8127874
    Abstract: When a time average of square values of charge-discharge current exceeds a predetermined reference value and when a state of charge of a battery is higher than a preset reference level, the procedure corrects a basic input limit set according to a battery temperature and the state of charge and sets the corrected basic input limit to an effective input limit. When the state of charge is lower than a preset reference level, the procedure of the invention corrects a basic output limit set according to the battery temperature and the state of charge and sets the corrected basic output limit to an effective output limit. This arrangement more adequately sets the effective input limit and the effective output limit, compared with a technique of simultaneously correcting the effective input limit and the effective output limit based on the temperature of the battery.

  • Patent number: 8102152
    Abstract: According to a deterioration detecting method for rechargeable lithium batteries, battery voltages of a rechargeable lithium battery before and after the completion of charging or discharging are measured. An evaluation value is calculated based on the measured battery voltages. This evaluation value is compared with a reference value of the rechargeable lithium battery stored in advance. A deterioration level of the rechargeable lithium battery is estimated based on this comparison result. In addition, further deterioration can be suppressed by controlling charging and discharging of the rechargeable lithium battery based on the estimated deterioration level.

  • Patent number: 8063611
    Abstract: A DC blocking capacitor and a resistor are coupled in series, and coupled in parallel with an electricity storing section. An ON/OFF circuit and a peak voltage holding circuit are coupled in parallel with the resistor. A current sensing section is coupled in series with the storing section, with its output supplied to the peak current holding circuit. Current from a positive to a negative electrode of the storing section is referred to as a positive direction. The ON/OFF circuit is turned on when the current flows in a negative direction, and is turned off when the current flows in the positive direction. An internal resistor of the storing section is found based on a peak voltage and a peak current resulting from the control and held by the respective circuits. A degree of degradation of the electricity storing section is determined with this internal resistor.

  • Patent number: 8013569
    Abstract: A renewable energy system for directly charging electric and hybrid vehicles is shown for areas with modest wind resources and/or solar resources. The invention consists of a composite stanchion for mounting on a base in a parking lot that is both capable of supporting a medium sized wind turbine (or solar array) and serving as a battery storage and charging control station. Significant improvements in blade pitch adjustment and cost reduction for wind turbine blades allow the system to operate at an acceptable cost in areas with modest winds and avoid the need for remotely supplied renewable electricity in areas of high population density. In turn, this will allow for increased electrical grid stability through increased use of distributed generation.
