| 摘要 |
A bridge circuit using a battery temperature sensing resistor and an ambient temperature sensing resistor provides signals which can be applied to an output circuit to cause a charging circuit to provide a relatively high charging current when the battery temperature is within a predetermined temperature region relative to the ambient temperature, and to provide a relatively low charging current when the battery temperature is above or below the predetermined temperature region. A memory circuit can be provided to prevent subsequent high charging currents.
