Abstract: According to one embodiment, a memory system comprises a first memory including a nonvolatile memory cell array, a second memory configured to operate at higher speed than the first memory, and a memory controller. The memory controller executes, in response to a write command from a host, data transfer from the host to the second memory, a data-in operation, and a program operation, with respect to first data instructed to be written by the write command.

Abstract: A physics-based calendar life model for determining the state of health of a lithium ion battery cell. The model accounts for parasitic reactions on anode and cathode particles to accurately determine degradation of a battery. By incorporating electrolyte decomposition in a cathode, the present calendar model can predict capacity retention as well as the substantial rise of cell resistance at high state of charge (SOC) and temperatures. The present calendar model is a simple algorithm, utilizing only three parameters, and determines the capacity retention and resistance rise based on temperature, SOC and time.

Abstract: An automatically generated and customized fast charging process results in reduced degradation in the battery cell. An algorithm for a particular battery cell profile is automatically generated and customized to minimize degradation due to fast charging for that particular batch. To generate the custom algorithm, battery cell information is retrieved for a profile of a battery, wherein each battery profile may have a particular manufacturer, model, type, electrode batch, and potentially other specific identification information. Each battery cell is charged from a particular SOC level and at a selected C-rate, and then discharged. During discharge, the battery cell is monitored for detection of lithium plating or other undesirable effects. A lookup table is automatically generated from the battery cell information, and can be provided to devices and/or battery management systems. The BMS then uses the lookup table to apply a charging process that is customized to the on-board battery.
