Abstract: A semiconductor device capable of turning a discharge control transistor off faster while maintaining safety is provided. A control unit, in discharge stopping processing, turns a switching element on and executes a first discharge-stopping mode in which the gate voltage of the discharge control transistor is withdrawn via a load and, at a predetermined discharge-stopping mode switching timing, switches to a second discharge-stopping mode in which the gate voltage of the discharge control transistor is withdrawn directly to a low-voltage power source.

Abstract: A power supply system can include an electrical battery for supplying electrical load using pulse discharge; and a control unit to control the electrical battery to pulse discharge by periodically switching between a discharge state of the electrical battery, when the electrical battery is connected to the electrical load, and a rest state of the electrical battery when the electrical battery is disconnected from the electrical load. During the pulse discharge, the control unit can control a power source for supplying an injection current to the electrical battery during a rest period when the electrical battery is in the rest state. The control unit can further determine the voltage of the electrical battery during the rest state, and when the voltage does not meet a threshold value increase the duration of the rest period, until said threshold value is reached. Other systems, methods and apparatuses are described.

Abstract: To perform charge/discharge control of a storage battery at an appropriate timing. In a battery controller, a battery information acquisition unit acquires information on the storage battery. A degradation progression rate calculation unit calculates a degradation progression rate of the storage battery based on the information acquired by the battery information acquisition unit. A limit value setting unit sets a limit value for controlling charge/discharge of the storage battery based on the degradation progression rate calculated by the degradation progression rate calculation unit. A timing determination unit determines a timing at which the limit value needs to be output based on the information acquired by the battery information acquisition unit. A limit value output unit outputs the limit value to a host controller based on the timing determined by the timing determination unit.

Abstract: The described technology includes a power distribution controller configured to control functioning of a first power source configured to supply power to a first component and to a second component and a second power source configured to supply power to the second component. The power distribution controller sets an upper limit of current from the first power source to the second component based on average level of charge at the second power source over a predetermined amount of time. The power distribution controller reduces the amount of power loss due to spikes in current from the first power source to the second component.
