Abstract
Electric vehicle (EV) charging stations for: (i) preventing damage to a battery of an EV charging station, and (ii) maintaining fast charging of the battery of the EV charging station. An EV charging station controller determines if an input power to the EV charging station is above an input power threshold value, and, if so, determines if a charge level of the battery of the EV charging station is below a low charge threshold level. If the charge level is below the low charge threshold level, a portion of the input power may be reserved for the battery of the EV charging station.
Claims19
An electric vehicle (EV) charging station controller of an EV charging station, comprising one or more processors configured to cause the EV charging station to:
- measure an input power, wherein the input power is a power received from a power source at an input port of the EV charging station;
- determine if the input power is above an input power threshold value;
- when the input power is above the input power threshold value, measure a battery charge level of a battery of the EV charging station;
- determine if the battery charge level is below a low charge threshold level;
- when the battery charge level is below the low charge threshold level, reserve a portion of the input power to charge the battery;
- and
- charge the battery with the reserved portion of the input power regardless of a power output requested by an EV;
- wherein the input power threshold value is a first input power threshold value, and wherein the EV charging station controller is further configured to cause the EV charging station to:
- determine if the input power is above a second input power threshold value;
- and
- when the input power is above the second input power threshold value, enable multiple charging heads of the EV charging station.
An electric vehicle (EV) charging station configured to prevent battery damage, the EV charging station comprising:
- an EV charging station battery;
- one or more processors;
- and
- a non-transitory program memory communicatively coupled to the one or more processors and storing executable instructions that, when executed by the one or more processors, cause the EV charging station to:
- measure an input power, wherein the input power is a power received from a power source at an input port of the EV charging station;
- determine if the input power is above an input power threshold value;
- when the input power is above the input power threshold value, measure a battery charge level of the EV charging station battery;
- determine if the battery charge level is below a low charge threshold level;
- when the battery charge level is below the low charge threshold level, reserve, for the EV charging station battery, a portion of the input power to charge the EV charging station battery;
- and
- charge the battery with the reserved portion of the input power regardless of a power output requested by an EV;
- wherein the input power threshold value is a first input power threshold value, and wherein the instructions, when executed, further cause the EV charging station to:
- determine if the input power is above a second input power threshold value;
- and
- when the input power is above the second input power threshold value, enable multiple charging heads of the EV charging station.
A computer-implemented method for preventing damage to a battery of an electric vehicle (EV) charging station, the method comprising:
- measuring, by one or more sensors of the EV charging station, an input power, wherein the input power is a power received from a power source at an input port of the EV charging station;
- determining, by an EV charging station controller of the EV charging station, that the input power is above an input power threshold value;
- in response to the determination that the input power is above the input power threshold value, determining, by the EV charging station controller, a battery charge level of the battery of the EV charging station;
- determining, by the EV charging station controller, that the battery charge level is below a low charge threshold level;
- in response to determining that the battery charge level is below the low charge threshold level, reserving, by the EV charging station controller, a portion of the input power to charge the battery;
- and
- charging the battery with the reserved portion of the input power regardless of a power output requested by an EV;
- wherein the input power threshold value is a first input power threshold value, and wherein the method further comprises:
- determining, by the EV charging station controller, that the input power is above a second input power threshold value;
- and
- in response to determining that the input power is above the second input power threshold value, enabling, by the EV charging station controller, multiple charging heads of the EV charging station.
