InactiveUS7183748B1Prevents wasteful power consumptionCancel a battery cutoff operationElectric powerArrangements for several simultaneous batteriesCharge controlBattery cell
A charging control unit decides the number of battery cells on the basis of an output voltage of a battery pack, and an output voltage of a charging circuit is determined in accordance with the decided number of battery cells. Even though supply of an external power supply is detected, when a battery connection is not detected, the power supply circuit of the charging control unit is set in a stop state. In addition, when disconnection of the battery is detected, a canceling voltage for canceling a cutoff state caused by overdischarging of the battery is output. In a power supply device for a portable terminal, a capacitor electrically charged by an output voltage of main DC / DC converter is connected as an auxiliary power supply of a backup DC / DC converter to make exchange of the auxiliary battery unnecessary.

A controller predicts a requested state of charge / discharge corresponding to a future run of a hybrid vehicle. If it is predicted that the hybrid vehicle will be stopped and restarted, or will be greatly accelerated and therefore that a request for a great discharge will be outputted in the future, the controller increases a target SOC of an HV battery to increase the value to which the charge of the HV battery will be converged in preparation for the great discharge. If it is predicted that a great regenerative electric power will be generated by a vehicle deceleration and therefore that a request for charging will be outputted, the target SOC is reduced, and the amount of charge in the HV battery is reduced, so that the regenerative power generated can be efficiency recovered.
