Abstract

Official abstract text for this publication.

A method of providing an electrical charge to a vehicle traction battery using a power inverter module includes sensing a temperature of the power inverter module and sensing a temperature of the traction battery. From the sensed temperatures, an engine control unit may determine an expected voltage oscillation amplitude of the electrical charge. This amplitude may be used to calculate a maximum allowable nominal voltage of the electrical charge by subtracting the expected voltage oscillation amplitude from a maximum allowable voltage of the traction battery. The maximum allowable nominal voltage of the electrical charge may then be used to limit the available power provided to the traction battery by the power inverter module.
