Ballman, G C

A battery charger has a control circuit portion and a power circuit portion with common terminals to connect to a battery desired to be recharged, the power circuit includes a transformer and rectifier to deliver at least partially rectified a-c current to the battery, and an a-c power connection through which a-c power is supplied to the power circuit with the control circuit having a solid state switch to selectively connect the a-c power to the power circuit portion. The control circuit portion of the charger has a d-c disconnect feature which senses the interruption in the electrical circuit between the charger's terminals and the battery, said disconnect feature causing the operation of the a-c power switching device to disconnect the a-c power from the power circuit after the terminals have been disconnected. A further feature is an a-c interrupt feature which senses the disconnection or interruption of a-c power from the power circuit, latches the a-c power turn off control in its off condition, interrupts the voltage following and timing charge control and maintains it in readiness for resumption of the charging cycle, at the interrupted point in the cycle, after the a-c power has been restored.
