17. A method for auto-voltage detection comprising:
-
applying a predetermined test charge to a battery; measuring the initial terminal voltage of the battery in response to the predetermined test charge; determining a condition of a battery based at least in part on the voltage response; applying a first predetermined precharge current to the battery for a first predetermined period of time; waiting a second predetermined period of time; applying a second predetermined precharge current to the battery for a third predetermined period of time; waiting a fourth predetermined period of time; determining a voltage rating of the battery based at least in part on the condition of the battery and a measured response to a precharge process; and charging the battery based at least in part on the voltage rating of the battery. - View Dependent Claims (18)
