Wataru ARATANI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Charge/discharge control apparatus, condition-of-use creation apparatus, non-transitory computer readable medium, and power storage system
    Patent number: 11462780
    Abstract: A charge/discharge control apparatus according to one aspect of the present invention is an apparatus that controls charge or discharge of a secondary battery to be charged or discharged on the basis of at least one condition of use calculated from a deterioration model or a deterioration map of a secondary battery and at least one inner state parameter of the secondary battery to be charged or discharged. The charge/discharge control apparatus updates the condition of use on the basis of change of the inner state parameter.
    Type: Grant

  • BATTERY SAFETY EVALUATION APPARATUS, BATTERY CONTROL APPARATUS, BATTERY SAFETY EVALUATION METHOD, NON-TRANSITORY COMPUTER READABLE MEDIUM, CONTROL CIRCUIT AND POWER STORAGE SYSTEM
    Publication number: 20180267108
    Abstract: A battery safety evaluation apparatus according to one aspect of the present invention includes a battery characteristic estimator, a heat amount estimator and safety index calculator. The battery characteristic estimator estimates an estimation value of an inner state parameter of a first battery on the basis of data on voltage and current of the first battery measured in charging or discharging. The heat amount estimator estimates a heat amount of the first battery upon change of an external temperature on the basis of first reference data which is at least indicating relationship between a heat amount of a secondary battery and the external temperature and is set to correspond to the first battery on the basis of the estimation value. The safety index calculator calculates a safety index regarding a temperature of the first battery upon change of the external temperature on the basis of the estimated heat amount.
