Single and multiple cell battery with built-in controller

摘要

Single and multiple cell batteries are provided with built-in controllers that monitor the cell or cells and provide a safety disconnect when certain monitored conditions are detected by the controller. Preferred single and multiple cell batteries have their cell or cells within a container having a positive terminal and a negative terminal. The built-in controller monitors the cell or cells for each of the following conditions: over temperature, short-circuit, overcharge, and over-discharge and the controller provides a safety disconnect when one of the monitored conditions exist. A multiple cell battery includes a built-in controller that monitors the temperature of the cells and provides a safety disconnect that electronically disconnects all of the cells when at least one of the cells exceeds a predetermined temperature, or a controller that monitors the state of charge of each of the cells and individually controls the charge cycle of each of the cells, or a controller that monitors the temperature of the cells and to provides a safety disconnect when at least one of the cells exceeds a predetermined temperature.
