Asymmetrical power output direct current fast charger

A direct current fast charger (DCFC) comprising:

• a first power module comprising a first rectifier and first control electronics;
• a second power module comprising a second rectifier and second control electronics, the second power module being configured to:
• receive a request to charge a battery of an electric vehicle (EV) at a specified charge rate;
• determine that the specified charge rate exceeds a maximum charge rate of the second power module;
• request additional power from the first power module on the DCFC;
• when the first power module has available power to donate to the second power module, receive donated power from the first power module;
• and
• charge the battery of the EV at an increased charge rate that exceeds the maximum charge rate of the second power module, the increased charge rate comprising a maximum power output of the second power module increased by the donated power from the first power module,
• wherein a power level of the first power module is capped at a reduced maximum power output, wherein the maximum power output of the second power module is higher than the reduced maximum power output of the first power module.

A non-transitory computer-readable storage medium comprising:

• computer-executable instructions for causing a direct current fast charger (DCFC) to:
• receive, via a first power module on the DCFC, a request to charge a battery of an electric vehicle (EV) at a specified charge rate;
• determine, via the first power module, that the specified charge rate exceeds a maximum charge rate of the first power module;
• request additional power from a second power module on the DCFC;
• when the second power module has available power to donate to the first power module, receive, via the first power module, donated power from the second power module;
• and
• charge, via the first power module, the battery of the EV at an increased charge rate that exceeds the maximum charge rate of the first power module, the increased charge rate comprising a maximum power output of the first power module increased by the donated power from the second power module,
• wherein a power level of the second power module is capped at a reduced maximum power output, and wherein the maximum power output of the first power module is higher than the reduced maximum power output of the second power module.
