METHOD AND APPARATUS FOR CHARGING A BATTERY WITH AC POWER BASED ON STATE OF BATTERY RELATED INFORMATION

Technology for charging at least one battery is described. An aspect of the technology involves charging a battery using alternating current (AC) power by periodically stopping () charging of a battery of a mobile energy storage and power consumption device (A) with AC power, and when charging of the battery with AC power is stopped, initiating () a direct current (DC) power charging communications cycle for the battery, in which the initiating the DC power charging communications cycle includes obtaining () state of battery related information for the battery by transmitting, over a communication link or interface, a request signal to a charging control device at the mobile energy storage and power consumption device indicating DC power charging mode of operation.
