Abstract
A generator-battery DC power supply system comprises a plurality of sub-systems each including a battery and a temperature sensor sensing the temperature of the battery and controlling the generator regulating means to decrease the generator output voltage in response to an increase in the sensed battery temperature, to thereby prevent overheating of the battery by over-charging same. The system further includes a bus-tie-contactor for connecting the sub-systems in parallel, and control means effective to control all the generators in response to the highest-sensed temperature of any battery in the sub-systems. The illustrated system is particularly useful in electrical power supply systems on aircraft.
Claims10
A power supply system comprising a plurality of sub-systems;
- each sub-system including a generator producing a DC output voltage, a battery supplying the power in case of failure or termination of operation of the generator, and generator regulating means regulating the output voltage of its respective generator;
- circuit means connecting the batteries of all said sub-systems in parallel;
- each of said generator regulating means including a temperature sensor sensing the temperature of its respective battery;
- comparator means for comparing the output of said temperature sensors and for determining the battery at the highest temperature;
- and control means effective to control the generator regulating means of all the generators of said sub-systems to decrease their output voltages in response to an increase in the temperature of the battery in the sub-system having the highest temperature, to thereby prevent over-heating of any of the batteries by over-charging them.
