Abstract

A power converter cartridge for a vehicle includes a housing slidably insertable into a body cavity of the vehicle and including electrical outlets and coolant, data, and power interface ports configured to connect to corresponding ports of the cavity, a converter, and a controller configured to, responsive to a signal from the vehicle via the data port, cause the converter to convert power received from a traction battery of the vehicle via the power interface port to supply corresponding external loads connected to the outlets.

First claim

What is claimed is:

1. A power converter cartridge for a vehicle comprising:
a housing slidably insertable into a body cavity of the vehicle and including
electrical outlets and coolant, data, and power interface ports configured to connect to corresponding ports of the cavity,
a converter operable to convert power received from a traction battery of the vehicle to at least two different voltage and current levels for supply to external loads connected to the outlets, and wherein the converter is further operable to convert alternating current power received from the outlets by an external power source to a direct current power for charging the battery, and
a controller configured to, responsive to a signal from the vehicle via the data port, cause the converter to convert power received from the traction battery of the vehicle via the power interface port to supply corresponding external loads connected to the outlets, wherein the controller is further configured to, responsive to another signal from the vehicle, cause the converter to convert power received at the outlets from the external power source connected thereto to charge the traction battery, wherein the coolant port is connected to a coolant system of the vehicle and is operable to circulate refrigerant through the housing to cool the converter when converting power received from the traction battery.

2. The cartridge of claim 1 , wherein the power is received from the battery and an engine.

3. The cartridge of claim 1 , wherein the causing is while a transmission of the vehicle is in PARK, DRIVE, REVERSE, or NEUTRAL.

4. The cartridge of claim 3 , wherein the causing is while a speed of the vehicle is greater than zero or while the vehicle is stationary.

5. A reconfigurable power system for a vehicle comprising:
an engine;
a traction battery; and
power converter cartridges, each slidable into a cavity of a body of the vehicle and including a converter, electrical outlets, and coolant, data, and power interface ports configured to connect to corresponding ports of the cavity such that the converter is operable to supply at least two different voltage and current levels to external loads connected to the outlets with converted energy received via the power interface port from the battery and engine, and the converter is further operable to convert alternating current power received from the electrical outlets by an external power source to a direct current power for charging the traction battery,
a controller configured to, responsive to a signal from the vehicle via the data port, cause the converter to convert power received from the traction battery of the vehicle via the power interface port to supply corresponding external loads connected to the outlets, wherein the controller is further configured to, responsive to another signal from the vehicle, cause the converter to convert power received at the outlets from the external power source connected thereto to charge the traction battery, and wherein the coolant port is connected to a coolant system of the vehicle and is operable to circulate refrigerant through the power converter cartridges to cool the converter when converting power received from the traction battery and when converting the alternating current power to the direct current power.

6. The system of claim 5 , wherein voltage and current ratings of the outlets of one of the cartridges are different from the corresponding ratings of the outlets of another of the cartridges.

7. The system of claim 5 , wherein connector recess configurations of the outlets of a same cartridge are different from one another, and the configurations of one cartridge are different from the corresponding configurations of another cartridge.

8. The system of claim 5 , wherein the supplying is while a transmission of the vehicle is in PARK, DRIVE, REVERSE, or NEUTRAL.

9. The system of claim 8 , wherein the supplying is while a speed of the vehicle is greater than zero or while the vehicle is stationary.
