Abstract

A high-efficiency reserve power battery charging system for a power plant or the like which stores a reserve charge in a rechargeable external battery. The system incorporates an intermediate storage battery and a charging control device for selectively storing charge in the intermediate storage battery during non-peak hours for later assistance in charging the external battery during peak hours.

Claims

1. An intermediate storage charging system, comprising:

an AC input power supply;

a rectifier selectively connectable to said AC power supply for generating a first charging current therefrom;

an intermediate storage battery for generating a second charging current, said intermediate storage battery being connected to an output of said rectifier and chargeable thereby from said first charging current;

a cyclic timing control device connected between said AC input power supply and said rectifier for sending an existing charge on said intermediate storage battery and for connecting said AC input power supply to said rectifier only during a preset time interval of non-peak power consumption and while said existing charge on said intermediate storage battery does not exceed a preset saturation level; and

at least one terminal storage battery coupled to the interconnected of said intermediate storage battery and the output of said rectifier and charged thereby from said first and second charging currents, said terminal storage battery being charged exclusively by the second charging current of said intermediate storage battery during times of peak power consumption to thereby level consumption of said first changing current.

2. The intermediate storage charging system according to claim 1, wherein said AC input power supply further comprises a monophase AC power supply.

3. The intermediate storage charging system according to claim 1, wherein said AC input power supply further comprises a multiple-phase AC power supply.

4. The intermediate storage charging system according to claim 1, wherein said rectifier further comprises a full diode bridge.

5. The intermediate storage charging system according to claim 1, wherein said cyclic timing control device further comprises a programmable timer for determining said preset time interval of non-peak power consumption, and a sensor for sensing said existing charge on said intermediate storage battery.

6. The intermediate storage charging system according to claim 1, wherein said at least one terminal storage battery further comprises a plurality of rechargeable storage batteries each coupled to the output of said rectifier, whereby the system may function to charge the plurality of terminal storage batteries simultaneously.

7. The intermediate storage charging system according to claim 1, further comprising an output control device connected between each of the plurality of terminal storage batteries and the output of said rectifier, said output control devices being one from among a group of charge-time controllers, charging voltage controllers, charging current controllers, and output measuring devices.

8. The intermediate storage charging system according to claim 1, further comprising an auxiliary DC input source selectively connectable to the interconnection of said intermediate storage battery, rectifier output, and terminal storage battery for generating a third charging current.
