Automatic and dynamic home electricity load balancing for the purpose of EV charging
First Claim
1. An electric vehicle charging system, comprising:
- 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;
an 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;
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.
