The removable module has a multipurpose connector that connect the removable module to a motor when the removable module is attached to a vehicle. Dual-purpose circuitry in the removable module can output electric energy to the motor when the multipurpose connector connects the removable module to the motor. The multipurpose connector can connect the removable module to the electric vehicle supply equipment when the removable module is detached from the vehicle. While the removable module is detached from the vehicle, the dual-purpose circuitry cannot output electric energy to the motor. When the multipurpose connector connects the removable module to the electric vehicle supply equipment, the dual-purpose circuitry can receive electric power from the electric vehicle supply equipment. ## Claims ### Claim 1 A method for operating a removable module, the method comprising: connecting, via a multipurpose connector, the removable module to a motor when the removable module is attached to a vehicle; outputting, from dual-purpose circuitry of the removeable module when the dual-purpose circuitry is operating in a first mode, electric energy to the motor when the multipurpose connector connects the removable module to the motor of the vehicle; connecting, via the multipurpose connector, the removable module to electric vehicle supply equipment when the removable module is detached from the vehicle; and receiving, by the dual-purpose circuitry when the dual-purpose circuitry is operating in a second mode, electric power from the electric vehicle supply equipment when the multipurpose connector connects the removable module to the electric vehicle supply equipment, wherein the dual-purpose circuitry is configured to perform as an inverter while in the first mode and to perform as power factor correction circuitry in the second mode. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: outputting, from combinational circuitry of the removable module, an auxiliary voltage to an auxiliary load when the combinational circuitry converts DC current into the auxiliary voltage. ### Claim 3 (depends on 2) The method according to claim 2, further comprising: converting, by the dual-purpose circuitry, the electric power into the DC current. ### Claim 4 (depends on 2) The method according to claim 2, further comprising: outputting, from the combinational circuitry, DC energy to an energy storage device when the combinational circuitry converts the DC current into the DC energy. ### Claim 5 (depends on 4) The method according to claim 4, further comprising: converting, by the dual-purpose circuitry when the dual-purpose circuitry receives an inverter mode connection DC voltage from the energy storage device, the DC voltage into the electric energy. ### Claim 6 (depends on 5) The method according to claim 5, wherein the energy storage device stores the DC energy as the DC voltage. ### Claim 7 (depends on 5) The method according to claim 5, further comprising: outputting, when the combinational circuitry converts the DC voltage into the DC energy, the auxiliary voltage from the combinational circuitry to the auxiliary load. ### Claim 8 (depends on 1) The method according to claim 1, further comprising: detecting, by sensing circuitry when the multipurpose connector connects the removable module to the electric vehicle supply equipment, a connection between the removable module and the electric vehicle supply equipment. ### Claim 9 (depends on 8) The method according to claim 8, further comprising: detecting, by the sensing circuitry when the multipurpose connector connects the removable module to the motor, a connection between the removable module and the motor.
