• assign a first target state of charge or second target state of charge corresponding to the at least one connected battery electric machine based on the at least one determined operating condition, wherein the second target state of charge is greater than the first target state of charge by at least a predefined threshold;
• and
• initiate charging of the at least one battery electric machine, via the at least one power source and the at least one power outlet, up to the first target state of charge or second target state of charge, or discontinue the charging based on the assignment and the at least one determined operating condition.
