Abstract: Methods and devices are provided for charging a battery in a temperature controlled charging process using a simple voltage-controlled charger. A control circuit includes elements for increasing the apparent voltage drop in a charging circuit, including a rechargeable battery, to produce a signal to a connected voltage-controlled charger to effect a lowering of the charger supplied charging current. This increased voltage drop is initiated upon sensing battery temperatures at or above a predetermined limit. In this way, a solely voltage-controlled charger may be controlled by battery temperature.
