<p>Variable Timing Circuit for Motive Power Battery Chargers A timing circuit for charging motive power batteries. The timing control circuit provides different times of charge in accordance with the time at which a preselected voltage/current state of the battery is attained and cooperates with a controller in causing termination of the charging operation upon the battery reaching the preselected state of charge. The timing circuit provides an automatic finish time period of charge if the battery reaches the predetermined voltage/current state at some time during the initial control time period. The control includes a switch 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 signals such a fault condition in the charging operation.</p> |
