  • Patent number: 8767367
    Abstract: With a wire protection method in accordance with the present invention, the method being used for supplying electric power from a power source to a load, an applied-current to the load is detected every predetermined time, A wire rise temperature is calculated using the detected applied-current I(n) and by a relational expression concerning heat radiation and heat generation of the wire. The calculated rise in temperature is added to a reference temperature so that a wire temperature is estimated. When the estimated wire temperature is lower than a predetermined upper limit temperature, the calculation of the rise in temperature is repeated. When the estimated wire temperature has become equal to or higher than the predetermined upper limit temperature, the electric power supply from the power source to the load is stopped so that the wire is protected.

  • Patent number: 8730635
    Abstract: If a power supply path is in an abnormal state, a power-supply-path protection circuit of a power supply controller inhibits a switching circuit that switches on/off power supply from a power source to a load from power supply, using data related to a protection-current temperature characteristic line set by a characteristic setting circuit. The protection-current temperature characteristic line has a characteristic in which a protection current value is constant corresponding to increase in an ambient temperature or a negative characteristic in which the protection current value reduces corresponding to increase in the ambient temperature. Within a temperature range equal to or lower than an supposed maximum ambient temperature around the power-supply-path, the protection-current temperature characteristic line and a power-supply-path temperature characteristic line have a relation that the protection-current value is equal to or lower than an allowable current value at an identical ambient temperature.
