Abstract
A battery control system for controlling the connection of a plurality of batteries to a load is provided. The system comprises a plurality of switches and a plurality of controllers. Each switch is operable to connect or disconnect one of the batteries from the load. Each controller is operatively coupled to one of the switches. Each controller is operative to cause one of the switches to disconnect one of the batteries from the load. Each controller has an input and an output for communicating with another controller wherein the controllers communicate with each other to limit the number of batteries that can be disconnected from the loads
Claims48
A battery control system for controlling the connection of a plurality of batteries to a load comprising:
- a plurality of switches each of which is operable to connect or disconnect one of the batteries from the load;
- and
- a plurality of controllers each of which is operatively coupled to one of said switches, each of said controllers being operative to cause one of said switches to disconnect one of the batteries from the load, each of said controllers having an output for communication with another of said controllers, each of said controllers also having an input for communication with another of said controllers, wherein said controllers communicate with each other to limit the number of batteries that can be disconnected from the load.
An UPS system having a plurality of batteries for providing backup power to a load comprising:
- a plurality of switches each of which is operable to connect or disconnect one of the batteries from the load;
- and
- a plurality of controllers each of which is operatively coupled to one of said switches, each of said controllers being operative to cause one of said switches to disconnect one of the batteries from the load, each of said controllers having an output for communication with another of said controllers, each of said controllers also having an input for communication with another of said controllers, wherein said controllers communicate with each other to limit the number of batteries that can be disconnected from the load.
A power plant system for providing power to a load comprising:
- a source of AC power;
- an AC to DC power converter for converting the AC power to DC power and for supplying the DC power to the load;
- an UPS system for providing backup DC power to the load, the UPS system comprising a plurality of batteries;
- a plurality of switches each of which is operable to connect or disconnect one of said batteries from the load;
- and
- a plurality of controllers each of which is operatively coupled to one of said switches, each of said controllers being operative to cause one of said switches to disconnect one of the batteries from the load, each of said controllers having an output for communication with another of said controllers, each of said controllers also having an input for communication with another of said controllers, wherein said controllers communicate with each other to limit the number of batteries that can be disconnected from the load.
