A method for charging a battery in an electric or hybrid vehicle provides an alternative to switching to low tap. In accordance with this method, if a tap cross occurs, an OBCM reduces its power limit by a configurable amount and then retries charging at a lower level. This process can be repeated as many times as it takes to find a power level that prevents a tap cross. Advantageously, the battery can be charged in the shortest amount of time instead of limiting the power to the low tap level. A charging system implementing the method is also provided.
