Abstract: A method comprises charging an electric vehicle using a connector connected at a first end to a direct current power source and at a second end to the electric vehicle, monitoring a state of charge of the electric vehicle, and when the state of charge exceeds a predefined state of charge level: disconnecting the first end of the connector from the direct current power source, connecting the first end of the connector to an alternating current source, and charging the electric vehicle using the connector connected at the first end to the alternating current source while the second end remains connected to the electric vehicle.

Abstract: Methods and apparatus are provided for predicting potential failure of wheel bearings in a vehicle. The apparatus includes a temperature sensor configured to measure a temperature value for a wheel bearing and a processor for comparing the temperature value to a threshold value. When the temperature value exceeds the threshold value, the process provides an indication to warn of the potential failure of the wheel bearing. The method includes operating the vehicle for a time period and measuring a temperature value for the wheel bearing after the time period. Next, the temperature value is compared to a threshold value for the wheel bearing. When the wheel bearing temperature value exceeds the threshold value, and indication is provided to warn of the potential failure of the wheel bearing.
