Abstract
An Adaptive Current-collector Electrochemical (ACE) system utilizes an array of contact pads and associated current control transistors to control localized current generation in discrete regions of a battery. Each contact pad is formed on a battery electrode (anode or cathode) and coupled to an associated discrete battery region, and is connected by an associated transistor to a current collection plate. Sensors are used to monitor operating parameters (e.g., localized current flow and operating temperature) of each discrete battery region, and a control circuit uses the sensor data to control the operating state of the transistors, whereby localized current flow through each transistor is increased, decreased or turned off according to measured local operating parameters. The control circuit utilizes local control circuits that process local sensor data using 'stand-alone' control logic, or a central controller that processes all sensor data and coordinates transistor operations.
