A method for charging a battery includes coupling an electrical device in a circuit between the battery and an electrical power source. The electrical device having on and off states that are mechanically different. The method includes charging the battery by setting the electrical device to the on state, measuring current flowing through contacts of the electrical device while in the on state, determining current as a function of time flowing through the contacts of the electrical device, using the current as a function of time as a variable in a thermal model based on heating of the contacts and cooling of the contacts, determining by the thermal model a predicted temperature of the contacts based on the current as a function of time and the heating and cooling of the contacts and controlling the on and off state of the electrical device based on the predicted temperature.

An integrated fuel management system can include a switching unit coupled to an electric vehicle (EV) charging station, a computer system, a first electronic unit, and a second electronic unit. The first electronic unit can be coupled to the switching unit and operable for providing state information for the EV charging station to the computer system. The second electronic unit can be coupled to a fueling station for types of vehicles that use fuel and operable for providing state information for the fueling station to the computer system. Further, the computer system can be operable for displaying the state information for the EV charging station and for displaying the state information for the fueling station.

To navigate an electric vehicle from a starting location to a destination, a system identifies multiple charging stations between the starting location and the destination and determining a navigation route that requires a least amount of time for the electric vehicle to travel from the starting location to the destination via one or more of the charging stations, including determining a non-linear relationship between an amount of time and an amount of charge the EV receives during the amount of time.
