Abstract
Official abstract text for this publication.
A battery management and protection system can include various features to improve safety-critical and other functions. Among the features that can be included in some implementations are automatic loading of safety or other parameters during start-up of the system; a centralized timekeeper and an event system that can trigger actions in the system independently of a central processing unit; use of the same modules for both automatically-controlled safety-related measurements and firmware-controlled measurements; enhanced diagnostic features, and a sleepwalking feature that allows certain modules in the system to continue to perform various functions even when the module or the system is in a low-power sleep mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery management and protection system having an active mode and one or more low-power sleep modes, the system comprising: a central processing unit that is inactive while the system is in the one or more low-power sleep modes; a module, other than the central processing unit, to receive signals indicative of an operational characteristic of a battery and to determine whether the characteristic is within a predetermined range; a timekeeper that inclu…
