Abstract
An example direct current fast charger (DCFC) for providing asymmetrical charging power to electric vehicles can include a first power module having a rectifier and control electronics, and a second power module having a rectifier and control electronics. The first power module can be 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 first power module; request additional power from the second power module; when the second power module has available power to donate, receive donated power from the second power module; and charge 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 including a maximum power output of the first power module increased by the donated power.
