摘要： A highly reliable protection element for a storage battery is provided. A protection element includes a low melting point metal body and heater elements. The low melting point metal body is connected to a charger side line and a storage battery side line of a charge/discharge circuit. The heater element is connected to the storage battery side line and a switch, and the heater element is connected to the charger side line and a switch. When the switches are operated, a voltage that is not affected by a voltage drop of the low melting point metal body is applied to one of the heater elements, so that the low melting point metal body can be reliably fused.

摘要： Embodiments of the present invention provide a power supply unit capable of achieving noise reduction while maintaining efficiency under the light load state. A FET driver controls switching elements in either one of a Pulse Width Modulation (PWM) mode, an intermittent mode having a lower operating frequency than that in the PWM mode, and a noise-free mode having a higher operating frequency than an audible frequency range. The FET driver operates first in the intermittent mode under the light load state. A microphone collects noise generated from the surroundings of a power supply unit. When the level of an audio signal collected by the microphone exceeds a predetermined level, the FET driver transitions from the intermittent mode to the noise-free mode. In accordance with such an embodiment, the FET driver operates in the noise-free mode only when noise is actually generated.

摘要： A charging system capable of charging a battery cell so that the surface temperature of the battery cell does not exceed an upper temperature limit, is provided. A battery charger is configured in a manner such that a setting current is variable during charging. The battery charger starts charging of a secondary battery with a setting voltage set to a minimum charging current value. The surface temperature of the secondary battery is measured during charging. An estimated temperature value is calculated which is a surface temperature of the secondary battery, at which the secondary battery is charged up until a charging amount corresponding to the maximum surface temperature under assumption that the charging is performed with a present charging current value. The setting current is increased when the estimated temperature value is lower than the target temperature range and is reduced when the estimated temperature value is higher than the target temperature range. When the estimated temperature value belongs to the target temperature range, a present setting current is maintained.
