Abstract
Systems and methods for controlling a dual active bridge converter are disclosed herein. An environmental condition associated with an electric charger for an electric vehicle may be determined, where the electric charger comprises a dual active bridge converter. Based on the environmental condition associated with the electric charger, the dual active bridge converter may be caused to enter a heat generation mode that causes the dual active bridge converter to generate heat to ameliorate the environmental condition associated with the electric charger.
Claims20
A method comprising:
- determining an environmental condition associated with an electric charger for an electric vehicle, wherein the electric charger comprises a dual active bridge converter, and wherein determining the environmental condition comprises determining that a temperature associated with the electric charger is below a threshold temperature;
- and
- in response to determining that the temperature associated with the electric charger is below the threshold temperature, causing the dual active bridge converter to enter a heat generation mode that causes the dual active bridge converter to generate heat to increase the temperature and ameliorate the environmental condition associated with the electric charger.
A system comprising:
- a dual active bridge converter;
- control circuitry configured to:
- determine an environmental condition associated with an electric charger for an electric vehicle by determining that a temperature associated with the electric charger is below a threshold temperature, wherein the electric charger comprises the dual active bridge converter;
- and
- in response to determining that the temperature associated with the electric charger is below the threshold temperature, cause the dual active bridge converter to enter a heat generation mode that causes the dual active bridge converter to generate heat to increase the temperature and ameliorate the environmental condition associated with the electric charger.
A system comprising:
- a first bidirectional converter capable of bidirectional power flow;
- a second bidirectional converter capable of bidirectional power flow;
- control circuitry configured to:
- determine an environmental condition associated with an electric charger for an electric vehicle, wherein the electric charger comprises the first bidirectional converter and the second bidirectional converter;
- and
- based on the environmental condition associated with the electric charger, cause the first bidirectional converter and the second bidirectional converter to enter a heat generation mode that:
- causes the first bidirectional converter and the second bidirectional converter to generate heat to ameliorate the environmental condition associated with the electric charger by causing current to circulate between the first bidirectional converter and the second bidirectional converter.
