Abstract: A battery management controller includes input channels to receive a voltage signal from a battery and output channels to provide diagnostic signals to an operator. The controller is programmed to output a diagnostic signal predictive of a thermal condition in response to the voltage decreasing at a rate greater than a predetermined rate that signals that the voltage is decreasing toward a local minimum that precedes an increase in the voltage indicative of a battery temperature increase rate becoming greater than a threshold. The diagnostic signal may be used to alert the operator of the condition. The controller may be further programmed to issue commands to mitigate the thermal condition based on the diagnostic signal.

Abstract: An electrolyte solution usable in a lithium or lithium-ion battery, among other types of batteries that offers one or more of the following: improved stability (e.g., stable discharge capacities even after several cycles), elimination of the risk of unintentionally producing hydrochloric acid, improved thermal stability, and reduced production costs associated with manufacturing a battery. Indeed, the inventors have discovered an unexpected result that by including an additive to a dinnimitride salt (e.g., LiDN), the discharge capacity of the battery may improve beyond what is available in the prior art, including LiPF6. For example, production costs may be decreased since LiDN is not water-sensitive, so precautions to ensure that the compound is not exposed to water may be avoided. Further benefits include thermal stability since LiDN may be more thermally stable when compared to LiPF6.
