Abstract

The invention relates to methods and apparatus for communication and balancing and communication in a battery system. The invention relates to methods and apparatus for communication and balancing in a battery system. The apparatus may include a battery pack connected to a management network. The management network may be configured to communicate with a master controller via a communication bus. The apparatus may be configured to operate in a communication mode and a balancing mode.

Description

technical field [0001] The present invention relates to methods and apparatus for autonomous balancing and communication in battery systems. Background technique [0002] An increasing number of battery-powered systems equipped with battery packs (ie, series-connected batteries) utilize active balancing techniques to improve the storage capacity and life cycle of the battery packs. Switched capacitor balancing techniques are often used for this purpose. Furthermore, it is generally desirable to monitor each cell in the battery pack to prevent unsafe conditions, such as overvoltage, undervoltage, excessive temperature, etc., by enabling safety mechanisms should such conditions be detected. Routine monitoring of each battery cell in a battery pack requires additional wiring beyond the basic pack wiring. Contents of the invention [0003] The present invention relates to methods and apparatus for autonomous balancing and communication in battery systems. [0004] The devic...
