Apparatus and method for detecting a phase sequence in a vehicle
First Claim
1. An apparatus for detecting a phase sequence in a vehicle, the apparatus comprising:
- a control module for being operatively coupled to a first sensing device and a second sensing device in a vehicle that receives an incoming power signal from a power grid, the first sensing device being arranged to provide a first voltage in response to the incoming power signal and the second sensing device being arranged to provide a second voltage in response to the incoming power signal, the control module being configured to;
determine a phase difference between the first voltage and the second voltage;
control a number of switching devices to generate an output voltage signal based on the phase difference to charge at least one battery on the vehicle; and
determine whether the power grid corresponds to one of a first split phase case and a second phase split case prior to controlling the number of switching devices to generate the output voltage signal.

Abstract
In at least one embodiment, an apparatus for detecting a phase sequence in a vehicle is provided. The apparatus includes a control module for being operatively coupled to a power grid for receiving an incoming power signal therefrom, the incoming power signal providing a first voltage and a second voltage in a vehicle. The control module is configured to determine a phase difference between the first voltage and the second voltage and to determine a signal frequency of the incoming signal to determine a country type for the power grid. The control module is further configured to control a number of switching devices to generate an output voltage signal based on the phase difference and the signal frequency to charge at least one battery on the vehicle.
