Automatic and dynamic home electricity load balancing for the purpose of EV charging
First Claim
1. A charging unit to charge a set of one or more electric vehicles, comprising:
- a processor and a non-transitory machine-readable medium that stores instructions that, when executed by the processor, cause the charging unit to;
receive a present electric current consumption value that represents a total present electric current consumption value at a single electric service panel in which the charging unit is connected,cause electric charging power to be supplied to the set of one or more electric vehicles through the single electric service panel such that the supplied electric charging power to the set of one or more electric vehicles is a value less than a difference between a maximum current capacity for the single electric service panel and a sum of the present electric current consumption value and a current consumption value of a largest expected electric consumer at the single electric service panel.

Abstract
An electric vehicle charging system includes logic collocated with an electric service panel to monitor a total present electric current consumption value for all electric consumers below a point in the service panel; a first input to receive the present electric current consumption value from the logic collocated with the service panel, and to compare the present electric current consumption value with a maximum current capacity value for the service panel; a second input to receive electric current from the service panel; an output to supply electric charging power to at least one electric vehicle; and logic to set an electric charging current drawn from the service panel through the second input and provided to the electric vehicle charging output to a value less than a difference between the maximum current capacity for the service panel and a sum of the present electric current consumption value and the current consumption value of a largest expected electric consumer.
