Abstract
Various disclosed embodiments include illustrative controller units, direct current fast charging (DCFC) units, and methods. In an illustrative embodiment, a controller unit includes a controller and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the controller to determine status of a power electronics module (PEM) of a direct current fast charging (DCFC) unit, and instruct the PEM to control power quality of a three-phase alternating current (AC) grid power signal in response to the determined status being available.
Claims17
A controller unit comprising:
- a controller;
- and
- a memory configured to store computer-executable instructions configured to cause the controller to:
- determine status of a power electronics module (PEM) of a direct current fast charging (DCFC) unit;
- instruct the PEM to control power quality of a three-phase alternating current (AC) grid power signal in response to the determined status being available;
- receive three-phase current values from a non-linear load sharing a three-phase grid power signal with the DCFC unit in response to the instruction to control power quality;
- and
- receive three-phase grid current values and voltage values from current sensors and voltage sensors disposed within the DCFC unit in response to the instruction to control power quality.
A direct current fast charging (DCFC) unit comprising:
- a power electronics module (PEM);
- a first controller;
- a memory configured to store computer-executable instructions configured to cause the first controller to:
- determine status of the PEM;
- and
- instruct the PEM to control power quality of a three-phase alternating current (AC) grid power signal in response to the determined status being available;
- a communication device configured to receive three-phase current values from a non-linear load sharing a three-phase grid power signal with the DCFC unit;
- current sensors configured to receive three-phase grid current values;
- and
- voltage sensors configured to receive three-phase grid voltage values.
A method comprising:
- determining status of a power electronics module (PEM) of a direct current fast charging (DCFC) unit;
- instructing the PEM to control power quality of a three-phase alternating current (AC) signal in response to the determined status being available;
- receiving three-phase current values from a non-linear load sharing a three-phase grid power signal with the DCFC unit in response to the instruction to control power quality;
- receiving three-phase grid current values from current sensors disposed within the DCFC unit in response to the instruction to control power quality;
- and
- receiving three-phase grid voltage values from voltage sensors disposed within the DCFC unit in response to the instruction to control power quality.
