    Abstract: A charge control method for an alkaline storage battery includes determining whether or not a temperature T of a battery is less than 0° C.; if the temperature T is equal to or higher than 0° C., determining whether or not the battery has been considered to be charged to a maximum capacity that can be stored in the battery; if the battery has not been considered to be charged to the maximum capacity, determining the temperature T of the battery again; if the battery has been considered to be charged to the maximum capacity, finishing the charging; if it is determined that the temperature T is less than 0° C., determining whether or not a specified voltage value has been reached, the specified voltage value having been preset in a range lower than a voltage value when the battery has been considered to be charged to the maximum capacity that can be stored in the battery; if the voltage value of the battery has not reached the specified voltage value, determining the temperature T of the battery again; and if the voltage value of the battery has reached the specified voltage value, finishing the charging.

    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on and executes a first discharge-stopping mode in which the gate voltage of the discharge control transistor is withdrawn via a load and, at a predetermined discharge-stopping mode switching timing, switches to a second discharge-stopping mode in which the gate voltage of the discharge control transistor is withdrawn directly to a low-voltage power source.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: 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.
