Abstract
A charging system for a battery of a vehicle comprises an electrical interface module that includes first and second electrical interfaces. An inverter module communicates with the electrical interface module and the battery and has a first state and a second state. In the first state, the inverter module allows the battery to be charged through the first electrical interface when a voltage source is connected to the first electrical interface, the vehicle is off, and a charge level of the battery is less than a threshold. In the second state, the inverter module allows the battery to provide power to the second electrical interface when a voltage source is not connected to the first electrical interface, the vehicle is on, and/or the charge level of the battery is greater than or equal to the threshold.
