Abstract
The present invention discloses methods and systems for scheduling and distributing power for electric vehicle chargers, through enabling and disabling a plurality of relays at a system. One of the criteria to allow an authenticated user to use an electric vehicle charger is whether there is enough electricity capacity. When the user is allowed to use a scheduled electric vehicle charger, its location is then sent to the user. Alert messages can be generated if charging does not begin within a first time limit and the cancellation of a reservation will take place if the second time limit is reached.
Claims20
A method performed at an electric vehicle (EV) charger, comprising:
- (a) enabling a plurality of relays;
- (b) creating a time scheduler;
- (c) monitoring time and a respective amount of current passing through each relay in the plurality of relays, wherein the time is monitored for determining whether more electricity should be provided to a load at the time;
- (d) disabling at least one relay in the plurality of relays if an amount of current passes through the at least one relay is more than a threshold;
- and
- (e) after a period of time, re-enabling the at least one relay.
An electric vehicle (EV) charger, comprising:
- at least one processing unit;
- and
- at least one non-transitory computer readable storage medium storing program instructions executable by the at least one processing unit for:
- (a) enabling a plurality of relays;
- (b) creating a time scheduler;
- (c) monitoring time and a respective amount of current passes through each relay in the plurality of relays;
- wherein the time is monitored for determining whether more electricity should be provided to a load at the time;
- (d) disabling at least one relay in the plurality of relays if an amount of current passing through the at least one relay is more than a threshold;
- and
- (e) after a period of time, re-enabling the at least one relay.
