View the Complete Application at the US Patent & Trademark Office
A vehicle may include at least one controller and a battery configured to be selectively charged with energy from an off-board energy source. The at least one controller may be configured to receive user input specifying a cost minimization mode of battery charging. The at least one controller may be further configured to, in response to the input, determine a time period available for charging the battery, determine when, during the time period, a cost of energy from the off-board energy source is at a minimum or below a threshold cost, and cause the battery to be charged during at least a portion of the time period when the cost is at the minimum or below the threshold cost to minimize the cost of charging the battery.
