With the emergence of the electric car, it will become very dihicult to accurately predict when the batteries have been charged for use.

ELECTRIC CAR CHARGING DEVICE EQUIPPED WITH PAGING SYSTEM

by Tim Dimacchia and Neil Gibson

  With the emergence of the electric car, it will become very dihicult to accurately predict when the batteries have been charged for use. With petroleum powered vehicles, it is simply a matter of visiting a fire1 station and refilling the fuel tank. In the case of electric vehicles, a user will be forced to rely on a method of manually timing the estimated recharge period, as well as, checking the charge capacity,

and Controller

The system would consist of several components. These components are as follows:

COMeCtiOll t0

(1) The Battery Charging Device

The charging device would connect an AC out- let to the charge connection of the automobile. This device may be the same device currently planned for use in these 'futuristic' automobiles. Additional designs might involve portable or hxed charging apparatus.

(2) The Page Transmission System

This system would transmit a predetined data message via RF transmission to the automobile owner. Pager information could be programmed from the factory or by other means (i.e. automo-

bile dash, personal computer, etc.)

(3) Battery Charge Level Detection Device

The battery charge level device would monitor the 'charge' state of the automobiles batteries. As the battery reached various charge states, a signal would be sent to the Page Transmission System. The Pag...
