Abstract: The present invention generally relates to a device and method for the management of a collection of battery cells. In one embodiment, the present invention permits the management of a collection of battery cells composed of an overall battery pack manager unit, individual cell manager units, and wireless communication links between these units. In another embodiment, the present invention relates to a device and method for the management of a collection of battery cells in the field of rechargeable batteries, such as batteries based on lithium-based chemistries, nickel-based chemistries, and lead-acid chemistries. In still another embodiment, the present invention is directed to a method that permits the maximization of battery pack capacity during a charge-discharge cycle and/or permits the maximization of the total number of charge-discharge cycles.

Abstract: The present invention generally relates to a device and method for stabilizing a battery pack, wherein the battery pack stabilization device has a by-pass circuit to prevent individual cell overcharge. In one embodiment, the present invention relates to an efficient balancing and monitoring system for use in an electric vehicle that utilizes nickel-zinc-based batteries. In another embodiment, the present invention relates to a device that permits over-voltage protection as well as the ability to monitor cell voltage. In still another embodiment, the present invention provides a method to coordinate multiple packs of cells within a vehicle so a driver could be aware of possible distance and time parameters, as well as a monitoring or alert system to inform the driver of reduced power, thus preventing damage to the cells.
