    摘要: A battery includes a battery monitoring system for performing a battery self test. The battery monitoring system is integrated into the battery and configured to monitor a first health of the battery. The battery monitoring system is configured to receive an input signal from a wired interface or a wireless interface. The input signal is configured to instruct the battery monitoring system to provide feedback regarding the first health of the battery and/or a second health of the battery monitoring system. The wired interface consists of a positive terminal and a negative terminal of the battery.

    摘要: An estimation apparatus of estimating a deterioration state of a secondary battery has a current sensor measuring an electric current of the secondary battery, a current estimating section estimating the electric current of the secondary battery by using a battery model, and a deterioration estimating section estimating a second deterioration component produced in association with a salt concentration imbalance in the secondary battery. The deterioration estimating section estimates the second deterioration component by using the measured current obtained from the current sensor, the estimated current obtained from the current estimating section, and a first deterioration component produced in association with wear of the secondary battery. The deterioration estimating section corrects the estimated current by using a ratio between a resistance change rate of the secondary battery when the second deterioration component is eliminated and a resistance change rate during charge and discharge of the secondary battery.

    摘要: A vehicle has an ECU, a battery being chargeable with off-board electricity and a motor driven by electric power of the battery. The ECU has a microcomputer to receive an operation time each time a user sets the ECU in an operation state, prepare a frequency of operation times for each time zone, and set a time of the time zone corresponding to the high frequency as a charging end target time. When the microcomputer receives a signal from an onboard charger connected with an off-board power source, the microcomputer sets a charging schedule such that the battery charged by the charger according to the schedule is set in a fully-charged state at the charging end target time. The microcomputer controls the charger to charge the battery according to the schedule and to set the battery in the fully-charged state at the charging end target time.
