Scalable intelligent power supply system and method
View Patent ↗A scalable intelligent power-supply system and method capable of powering a defined load for a specified period of time is disclosed and claimed. Multiple external AC and DC inputs supply power to the system if available and required. An internal DC input from a back-up energy source is on board. The back-up energy source is scalable by adding additional energy cartridges such as batteries in racks mounted within frames of the system. The AC and DC inputs (including the internal DC input) are controlled, measured, sensed, and converted by circuitry controlled by the microprocessor into multiple AC and/or DC outputs. A microprocessor manages power input to, within, and output from the system. The performance of a Lithium-ion batteries used to power an automobile can be determined on the basis individual battery packs or individual battery cells within the packs. This enables the clusters or groups of Lithium ion batteries to be used in a vehicle such that these clusters operate and function as a “gas” tank or more appropriately as an “energy” tank.
1. A power supply, comprising:
a plurality of quick disconnect removable cartridge battery packs;
each of said quick disconnect removable cartridge battery packs is switchably interconnected to a battery bus interconnected with a load;
each of said quick disconnect removable cartridge battery packs is switchably interconnected to a charge bus;
each of said quick disconnect removable cartridge battery packs is switchably interconnected to a battery information bus;
said plurality of quick disconnect removable cartridge battery packs includes first, second, third, and fourth portions thereof;
a microprocessor, said microprocessor switchably interconnecting a first portion of said plurality of quick disconnect removable cartridge battery packs with said battery bus such that electrical current may flow from said first portion of said plurality of said quick disconnect removable cartridge battery packs to said battery bus but not from said battery bus to said first portion of said plurality of said quick disconnect removable cartridge battery packs;
said microprocessor switchably interconnecting a second portion of said plurality of quick disconnect removable cartridge battery packs with said charge bus such that electrical current may flow from said charge bus to said second portion of said plurality of quick disconnect removable cartridge battery packs but not from said second portion of said plurality of quick disconnect removable cartridge battery packs to said charge bus;
said microprocessor switchably interconnecting a third portion of said plurality of quick disconnect removable cartridge battery packs with both said battery bus and said charge bus such that electrical current may flow from said third portion of said plurality of said quick disconnect removable cartridge battery packs to said battery bus but not from said battery bus to said third portion of said plurality of said quick disconnect removable cartridge battery packs, and, such that electrical current may flow from said charge bus to said third portion of said plurality of quick disconnect removable cartridge battery packs but not from said third portion of said plurality of quick disconnect removable cartridge battery packs to said charge bus;
said microprocessor switchably disconnecting a fourth portion of said plurality of quick disconnect removable cartridge battery packs from both said charge bus and said battery bus such that no current may flow from said fourth portion of said plurality of quick disconnect removable cartridge battery packs to either said battery bus or said charge bus and,
wherein each of said quick disconnect removable cartridge battery packs of said plurality of quick disconnect removable battery packs resides in precisely one of said first, second, third and fourth portions of said plurality of quick disconnect removable cartridge battery packs.
