Abstract

A battery system has a battery management system configured to determine a state of charge and a state of health of a secondary battery. The battery management system can output data to and receive input from a remote computer that calculates at least a portion of the state of health of the battery.

Description

[0001] Statement Regarding Federally Funded Research [0002] This invention was made with government support under ARPA-E Award No. DE-AR0000278 awarded by the United States Department of Energy. The US Government has certain rights in this invention. technical field [0003] The present invention relates generally to batteries, and more particularly to the operation of managing batteries. Background technique [0004] Rechargeable lithium batteries are attractive energy storage devices for portable electrical and electronic devices and electric and hybrid vehicles because of their high specific energy compared to other electrochemical energy storage devices. A typical lithium battery includes a negative electrode, a positive electrode, and a separator positioned between the negative electrode and the positive electrode. Both electrodes contain active species that reversibly react with lithium. In some cases, the negative electrode can include lithium metal, which can be...
