Embodiment Construction

[0131] figure 1 An embodiment of a testing system 110 for determining battery performance during development of a battery configuration under test is highly illustrative. An exemplary battery 112 is shown. The battery 112 may be a rechargeable battery. The battery 112 may be selected from the group consisting of: lithium ion battery (Li-Ion), nickel cadmium battery (Ni-Cd), nickel metal hydride battery (Ni-MH). For example, the battery may include at least one cathode material selected from the group consisting of LiCoO2 (lithium cobalt oxide), LiNixMnyCozO2 (lithium nickel manganese cobalt oxide), and LiFePO4 (lithium iron phosphate). For example, the cell may include at least one anode material selected from the group consisting of graphite, silicon. For example, the battery may contain at least one electrolyte selected from the group consisting of LiPF6, LiBF4, or LiClO4 in an organic solvent such as ethylene carbonate, dimethyl carbonate, and diethyl carbonate.

Abstract

A test system (110) for determining battery performance during battery configuration development in a test environment is presented. The test system (110) comprises at least one communication interface (114) and at least one processing device (122). The test system (110) is configured to receive operational data indicative of at least one test protocol via the communication interface (114). The test system (110) is configured to receive battery performance input data via the communication interface (114). The processing device (122) is configured to determine at least one predicted time series of at least one state variable indicative of battery performance based on the battery performance input data and the operational data using the at least one data-driven model. The test system (110) is configured for providing at least part of the predicted time series of state variables.
