Abstract

An apparatus for charging electric storage batteries comprises a host computer for providing charging information to and receiving status information from a plurality of slave computers. The slave computers are coupled to the host computer by means of a fiber optic data link. A plurality of control modules are coupled to each slave computer. Each control module applies charging current to a plurality of electric storage batteries in response to instructions received from the slave computer. Each control module also sends charging and battery temperature status information back to its respective slave computer.

Claims

1. An apparatus for charging electric storage batteries, said apparatus comprising:

(a) a host computer for providing charging information to and receiving status information from at least one slave computer by means of a data link; and

(b) at least one control module coupled to said slave computer for applying charging current to at least one electric storage battery in response to instructions received from said slave computer, and for providing feedback and status information to said slave computer.

2. An apparatus in accordance with claim 1 wherein said data link comprises a fiber optic data link.

3. An apparatus in accordance with claim 1 wherein said control module comprises:

(a) means for supplying direct electrical current of a predetermined, adjustable magnitude; and

(b) means for monitoring the magnitude of said direct current.

4. An apparatus in accordance with claim 3 wherein said control module additionally comprises:

(a) means for monitoring the temperature of said battery; and

(b) means for controlling the temperature of said battery.

5. An apparatus in accordance with claim 4 additionally comprising:

(a) means for comparing Kwh demand being used against a predetermined minimum level; and

(b) means for increasing charging power applied to batteries in accordance with a predetermined schedule when the Kwh demand is reduced to said predetermined minimum level.

6. An apparatus in accordance with claim 4 additionally comprising means for comparing predetermined charging parameters with predetermined failure limits and automatically removing charging power in the event that a predetermined parameter exceeds its respective failure limit.

7. An apparatus in accordance with claim 6 additionally comprising means for providing an alarm in the event that a predetermined parameter exceeds its respective failure limit.

8. An apparatus in accordance with claim 4 additionally comprising a scheduling computer for receiving, formatting and displaying status schedule and inventory information from said slave computer by means of a data link.

9. An apparatus in accordance with claim 1 additionally comprising means for energy management control comprising:

(a) means for receiving a signal representative of Kwh demand being consumed;

(b) means for comparing Kwh demand being used against a predetermine maximum level; and

(c) means for reducing charging power applied to batteries in accordance with a predetermined priority schedule when the Kwh demand exceeds said predetermined maximum level.

10. An apparatus in accordance with claim 5 wherein said data link comprises a fiber optic data link.

11. An apparatus in accordance with claim 1, comprising at least two control modules, wherein said control modules are sequentially activated in order to stagger re-application of charging current to the batteries in accordance with a predetermined schedule following a power failure.
