ABSTRACT:
A timing circuit for charging motive power batteries (B). The timing control circuit (25) provides different times of charge in accordance with the time at which a predetermined voltage/current state of the battery is achieved. Control circuit (25) cooperates with a controller (18) in causing termination of the charging operation immediately upon reaching of the voltage/current state if this occurs in a first time slot of an initial control time period. The timing circuit (25) provides an automatic finish time period of charge if the battery (B) reaches the predetermined voltage/current state at some time during the initial control time period. The control includes a switch (23) permitting the user to cause an automatic additional amount of charging upon completion of the normal charging cycle effected by the control, such as for effecting a weekend charge. The control further includes structure for terminating the charging operation in the event the battery being charged does not reach the predetermined voltage/current state at the end of a preselected maximum time. A signal light (24) signals such a fault condition in the charging operation.
