ELECTRIC CHARGING POWER MANAGEMENT
First Claim
Patent Images
1. A power management system, the system comprising:
- a processor configured to execute a set of instructions;
a link to a power supply; and
a set of branches, each branch configured to selectively provide power from the link to one or more rechargeable devices responsive to control from the processor;
wherein the set of instructions, when executed by the processor, cause the processor to;
receive a request to provide electrical power to a rechargeable device including a rechargeable battery;
determine a set of charging parameters responsive to the request, the set of charging parameters indicating a length of time over which to provide the requested electrical power and an amount of electrical power to provide;
identify an electrical resource available for a block of time compatible with the set of charging parameters, the identified electrical resource including a branch in the set of branches; and
issue one or more control instructions to route electrical power from the power supply via the identified electrical resource to the rechargeable device during the block of time responsive to the request.

Abstract
Power management systems and methods are used to charge batteries and battery-powered devices over an allotted period of time. A finite amount of source power is allocated and distributed across multiple devices according to a schedule. Users submit requests for time slots in the schedule. For example, a charging platform for electric vehicles can prioritize recharging vehicles that have impending departure times and defer recharging vehicles that are expected to remain present longer.

11. A method of allocating electrical power in a power management system, the method comprising:
-
receiving, by a processor, a request to provide electrical power to a rechargeable device; determining, by the processor, a set of charging parameters responsive to the request, the set of charging parameters indicating a length of time over which to provide the requested electrical power and an amount of electrical power to provide; identifying, by the processor, an electrical resource available for a block of time compatible with the set of charging parameters, the identified electrical resource including a branch from a set of branches, each branch configured to selectively provide power from a power supply to one or more rechargeable devices responsive to control instructions from the processor; and issuing, by the processor, one or more control instructions to route electrical power from the power supply via the identified electrical resource to the rechargeable device during the block of time responsive to the request. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
