ABSTRACT:
A charge control apparatus and method for charging of an electrical energy storage device, such as a rechargeable storage battery, by an electrical energy source, such as a photovoltaic panel, provides multiple charge setpoint selection means wherein the electrical connection of one or more setpoint control terminations to the three electrical potential contacts storage device "+", no contact (NC), or common "-", produces a specific and predefined charge setpoint condition, including charge termination and resumption voltage thresholds, from a plurality of charge setpoint possibilities. Temperature compensation is employed in multiple setpoint charge control to maintain setpoint thresholds essentially constant with apparatus temperature and to effect a change in setpoint thresholds with storage device temperature in accordance with storage device charging characteristics.
