A temperature rise pattern is retrieved from charging time based on the difference between a battery temperature at the beginning of battery charge and a target temperature value which a battery is intended to reach. A particular method includes applying one or more communication traces and one or more power traces to a structure using at least one direct-write technique. An automatic calibration routine may be used to determine nominal amounts of current over-reporting that may be used to prevent the processor performance from exceeding the maximum turbo mode. Particular designs of the fluidizing plate feature the disposition of a central through hole for the shaft of a stirrer mechanism, and an opening for the emptying of the fluidization vessel.
