ABSTRACT:
Electrical charging control apparatus regulates the charging of a rechargeable battery by a solar panel. The control of the charging is through a relay which when closed directly connects the output and charging terminal of the solar panel to the output and charging terminal of the battery to permit the charging of the battery by the solar panel. Such coupling is in turn under the control of signal-tester apparatus which prevents the coupling when the signals at the uncoupled terminals are in a coupling prevention relationship chosen to prevent significant discharging of the battery through the solar panel; of breaker apparatus which breaks a coupling after a predetermined period of time; and of additional signal-tester apparatus which causes a termination of the coupling when the signal at the connected terminals reaches a chosen charging termination threshold. The breaking of the coupling, which can result in a periodic breaking, permits the testing for discharging prevention. A charging control method is in accordance with the above outlined method of operation of the charging control apparatus.
