Abstract

A method of managing a battery system, the method comprising: receiving at least one measured characteristic of at least one battery cell from at least one sensor, estimating at least one battery cell at a first at least one state of time, estimating at least one physical parameter of at least one battery cell based on the at least one measured characteristic and an estimate of the at least one state, by applying an electrochemical-based battery model based on the estimated at least one parameter At least one state is estimated at a second time after the first time, and at least one of charging or discharging of at least one battery cell is adjusted based on the estimate of the at least one state.

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 US 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 management of the operation of secondary batteries. Background technique [0004] Rechargeable lithium batteries are attractive energy storage devices for portable electrical and electronic devices as well as electric and hybrid electric vehicles because of their high specific energy compared to other electrochemical energy storage devices. A typical lithium battery contains a negative electrode, a positive electrode, and a separator between the negative and positive electrodes. Both electrodes contain active materials that reversibly react with lithium. In some cases, the negative electrode can include lithium metal, which can ...
