  • Patent number: 10766378
    Abstract: An ECU is configured to perform output restriction control if first and second conditions are satisfied when a cell temperature is more than a threshold temperature determined based on a thermal destruction temperature of a sealing member. On the other hand, the ECU is configured not to perform the output restriction control if one of the first and second conditions is not satisfied even when the cell temperature is more than the threshold temperature. The first condition is satisfied when an acceleration time period is more than a predetermined time period. The second condition is satisfied when the temperature increase ratio of the cell is more than a restriction value.

    Abstract: A control system for a battery includes a current sensor and an electronic control unit. The electronic control unit is configured to calculate a first error and a second offset error of the current sensor respectively based on outputs of the current sensor just before a stop of the electronic control unit and at startup of the electronic control unit. The electronic control unit is configured to correct an output of the current sensor by using a first error when a temperature of the current sensor at startup of the electronic control unit is higher than or equal to a threshold temperature, and correct the output of the current sensor by using a second error when the temperature of the current sensor at startup of the electronic control unit is lower than the threshold temperature.

  • Patent number: 9744874
    Abstract: An electric vehicle includes: a vehicle drive apparatus configured to receive electricity to generate vehicle drive power and to generate electricity; a secondary battery that selectively receives and outputs electricity from/to the vehicle drive apparatus; a current sensor that selectively detects (a) an electric current to be input into the secondary battery and (b) an electric current output from the secondary battery; and an electronic control unit configured to control charging and discharging of the secondary battery, and configured to calculate, using a detected value from the current sensor, an evaluation value indicating a degree of deterioration of the secondary battery due to non-uniformity in salt concentration in the secondary battery caused by charging and discharging of the secondary battery. The electronic control unit is configured to execute a capacity-raising control in which a remaining capacity of the secondary battery is raised when the evaluation value reaches a prescribed threshold.

  • Patent number: 9656662
    Abstract: In a hybrid vehicle, an ECU executes a forced charging control for forcibly charging a battery by using an engine and a vehicle driving device in a case where a remaining capacity of the battery is equal to or less than a predetermined value. In a case where an evaluation value shows a degree of deterioration of the battery attributable to excessive charging, the ECU uses a first electric power as an electric charging power for charging the battery when an absolute value of the evaluation value is equal to or lower than a first threshold, and uses a second electric power falling short of the first electric power as the electric charging power for charging the battery when the absolute value of the evaluation value is higher than the first threshold in a case where the forced charging control is executed while the hybrid vehicle is stopped.
