Vehicle time delay battery charger
First Claim
1. An apparatus for switching one or more terminal pairs in an automobile after one or more time periods, the one or more time periods beginning once an automobile engine is turned off, comprising:
- a. engine sensing means;
b. timing means coupled to said engine sensing means, said timing means receiving an engine signal from said engine sensing means when the automobile engine is turned off and providing each one of one or more responses after a corresponding one of the one or more time periods has ended; and
c. switching means coupled to said timing means for receiving the one or more responses from said timing means, each one of the one or more responses corresponding to a number of the one or more terminal pairs, said switching means switching said number of the one or more terminal pairs once a corresponding one of the one or more responses is received.

Abstract
A device for providing vehicle battery power to rechargeable devices in vehicles, such as portable radios, cell phones, flashlights and laptop computer terminals left in patrol vehicles. The device has battery power as input, and outputs power to rechargeable devices while the vehicle is on, and for a time period thereafter. One device has multiple outputs having corresponding time periods. One device includes an engine sensor, a timer, a first switch and a second switch, with the first switch coupled to a first rechargeable device through a first terminal pair and the second switch coupled to a second rechargeable device through a second terminal pair. Each terminal pair can have a unique time period and, in some embodiments, can have one of a set number of time periods selected with a jumper.
