INTELLIGENT POWER MANAGEMENT SYSTEM, INCLUDING AUTONOMOUS BATTERY SELF-CHARACTERIZATION
A system for characterizing a battery of a battery electric system includes a sensor array, processor, and memory. The sensor array measures a temperature-specific battery voltage and battery current of the battery as battery parameters. The processor executes instructions from memory to provide or create a baseline open circuit voltage to state of charge (OCV-SOC) characteristic relationship during a sequence of charging and discharging modes of the battery. After creating or accessing the baseline OCV-SOC characteristic relationship, the processor determines if the battery is in an open mode during which the battery is not connected to a load. In open mode, the battery parameters are measured via the sensor array. An adjusted OCV-SOC characteristic relationship is created by adjusting an SOC quantity of the baseline OCV-SOC characteristic relationship using the battery parameters. The battery is controlled using the adjusted OCV-SOC characteristic relationship.

A physical vapor transport (PVT) apparatus for growth of silicon carbide (SiC) ingots can be improved by incorporating a moveable source. During growth of the ingot, the shape of the growth interface can be maintained as a convex shape by keeping a substantially constant distance between the growth interface and the source material. It is shown that temperature gradients during the growth phase are also influenced by the shape of the growth interface. By moving the source during crystal growth, the resulting SiC ingot can be taller with fewer defects, and can be less likely to crack during subsequent grinding or polishing operations.

A battery monitoring system (BMS) for a battery of a battery electric system includes a sensor array, a processor, and memory. Execution of the instructions causes the processor to receive battery parameters from the sensor array during respective charging and discharging modes of the battery, including at least a voltage, current, and temperature of the battery. Separate charge-side and discharge-side resistances of the battery are determined during charging and discharging modes, followed by calculation of a degradation level of the battery using the charge-side and discharge-side resistances. The processor may also perform a preventive action in response to the degradation level exceeding a calibrated threshold.
