An electrical energy absorption and heat storage system absorbs electrical energy transferred during a calibration process of an electric vehicle charging station. The system includes a resistive load, which, in operation, receives electrical energy and converts the electrical energy into heat. The heat is transferred to and stored in one or more heat storage mediums and then dissipated. The heat storage mediums may include phase-change heat storage mediums, such as water, solid heat storage mediums, such as ceramic mass (e.g., alumina), or combinations thereof. The stored heat may be dissipated as steam, contained for later dissipation, or combinations thereof. Heat sinks, convection and conduction cooling may be employed to dissipate the stored heat. An energy status of the system, together with information regarding the characteristics of the calibration process, may be used to determine whether it is appropriate to use the system to absorb the heat of the calibration process.
