A device suitable for battery charging and a device that predicts the state of charge is complex. To reduce the number of components, an effort was initiated to combine the battery charger and a state-of-cycle indicator because the sensors, processor, displays, and controls can be shared. State-of-charge information can be used by the battery charger for better charging procedures. Also, the computational capability of the state-of-charge indicator can also be used by the charger to optimize charge control. These considerations prompted by US DOE to direct JPL to develop a battery charger/state-of-charge indicator (BC/SCI) system for electric vehicle use under contract to Gould Laboratories. This report describes the original and subsequent objectives for the BC/SCI and the rationale for those objectives. The requirements generated from the objectives, both the original and reduced, are listed. A description of the BC/SCI is provided. A complete discussion of the power section problem is given and recommendations made for solving that problem. Other recommendations are provided for the state-of-charge indicator. One section of this report deals with the tests performed by JPL on the BC/SCI.
