Claim 0:
1. A method, comprising:
detecting that an ambulatory infusion pump configured to contain a medicament and having a rechargeable battery has been placed on an inductive charging device;
initiating charging of the rechargeable battery of the ambulatory infusion pump with the inductive charging device by transmitting power to the ambulatory infusion pump at a first charging rate;
detecting a plurality of temperature values within the ambulatory infusion pump while transmitting power to the ambulatory infusion pump at the first charging rate;
determining a rate of change of the plurality of temperature values;
comparing the plurality of temperature values and the rate of change of the plurality of temperature values within the ambulatory infusion pump to one or more predetermined thresholds relating to a medicament sensitivity threshold temperature, the medicament sensitivity threshold temperature being a temperature at which the medicament configured to be contained within the ambulatory infusion pump can become negatively affected by the temperature; and
if a temperature value of the plurality of temperature values and the rate of change of the plurality of temperature values within the ambulatory infusion pump is below the one or more predetermined thresholds, causing the inductive charging device to continue to transmit power to the ambulatory infusion pump at the first charging rate, and
if one or more of the temperature value of the plurality of temperature values and the rate of change of the plurality of temperature values within the ambulatory infusion pump is above a first threshold of the one or more predetermined thresholds and below a second threshold of the one or more predetermined thresholds higher than the first threshold, causing the inductive charging device to reduce the first charging rate to a second charging rate lower than the first charging rate, and
if one or more of the temperature values of the plurality of temperature values and the rate of change of the plurality of temperature values within the ambulatory infusion pump is above the second threshold higher than the first threshold, causing the inductive charging device to suspend charging of the ambulatory infusion pump.
