REMOVABLE MODULE
A removable module and a method for operating the removable module. 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.
1 . A removable module comprising:
a multipurpose connector configured to:
connect the removable module to a motor when the removable module is attached to a vehicle, and
connect the removable module to electric vehicle supply equipment when the removable module is detached from the vehicle; and
dual-purpose circuitry configured to:
receive electric power from the electric vehicle supply equipment when the multipurpose connector connects the removable module to the electric vehicle supply equipment, and
output electric energy to the motor when the multipurpose connector connects the removable module to the motor.
2 . The removable module according to claim 1 , further comprising:
combinational circuitry configured to:
output an auxiliary voltage to an auxiliary load when the combinational circuitry converts DC current into the auxiliary voltage.
3 . The removable module according to claim 2 , wherein the dual-purpose circuitry is configured to convert the electric power into the DC current.
4 . The removable module according to claim 2 , wherein the combinational circuitry is configured to output DC energy to an energy storage device when the combinational circuitry converts the DC current into the DC energy.
5 . The removable module according to claim 4 , wherein the dual-purpose circuitry is configured to convert a DC voltage into the electric energy when the dual-purpose circuitry receives the DC voltage from the energy storage device.
6 . The removable module according to claim 5 , wherein the energy storage device is configured to store the DC energy as the DC voltage.
7 . The removable module according to claim 5 , wherein the combinational circuitry is configured to output the auxiliary voltage to the auxiliary load when the combinational circuitry converts the DC voltage into the DC energy.
8 . The removable module according to claim 1 , further comprising:
sensing circuitry configured to:
detect that the removable module is connected to the electric vehicle supply equipment when the multipurpose connector connects the removable module to the electric vehicle supply equipment.
9 . The removable module according to claim 8 , wherein the sensing circuitry is configured to detect that the removable module is connected to the motor when the multipurpose connector connects the removable module to the motor.
