Abstract:
1. Hybrid power source equipment, comprising: a nonaqueous secondary battery; a secondary battery protecting circuit connected in parallel with said secondary battery; and a solar cell connected to said secondary battery, said secondary battery protecting circuit including said first voltage detecting circuit comprises a first resistance voltage-dividing circuit connected in parallel with said secondary battery, having a temperature detecting section and including a voltage outputting portion, and a first circuit whose input portion is connected to said voltage outputting portion of said first resistance voltage-dividing circuit and which turns ON in response to a voltage in said first circuit input portion being greater than or equal to a first reference voltage value, said second voltage detecting circuit comprises a second resistance voltage-dividing circuit connected in parallel with said secondary battery and including a voltage outputting portion, and a second circuit whose input portion is connected to said voltage outputting portion of said second resistance voltage-dividing circuit and which turns ON in response to a voltage in said second circuit input portion being greater than or equal to a second reference voltage value, said switch section and said heat radiating section are connected in series with each other and are connected in parallel with said secondary battery, said switch section operates in response to outputs from said first circuit and said second circuit, and when at least one of said first circuit and said second circuit is in an ON state, said switch section is in a conduction state, and an electric power accumulated in said secondary battery is transformed into heat by said heat radiating section.
