System and method for generating battery alarms in infusion devices

A medical device comprising:

• a rechargeable battery;
• a user interface;
• a battery sensor;
• a processor communicatively coupled to the battery sensor;
• and
• a memory storing a plurality of trained neural networks for different rechargeable battery types and instructions that, when executed by the processor, cause the processor to:
• determine, from the rechargeable battery, information indicative of a type of the rechargeable battery,
• select one of the plurality of trained neural networks based on the information indicative of the type of the rechargeable battery,
• at least one of receive or determine, at predetermined intervals of time in real-time, measurements comprising at least three of:
• a voltage of the rechargeable battery from the battery sensor,
• a change in the voltage over the predetermined intervals of time,
• an average current associated with the rechargeable battery from the battery sensor,
• a temperature of the rechargeable battery from the battery sensor, and
• a remaining voltage or capacity of the rechargeable battery,
• generate a feature vector comprising a full charge voltage or capacity of the rechargeable battery in addition to the at least three of the voltage, the change in the voltage, the average current, the temperature, and the remaining voltage or capacity,
• apply the feature vector to the selected trained neural network to determine an actual remaining voltage or capacity of the rechargeable battery, and
• generate, in real-time, an alarm when the actual remaining voltage or capacity of the rechargeable battery is below at least one of a first threshold corresponding to a low battery state, a second threshold corresponding to a very low battery state, and a third threshold corresponding to a depleted battery state,
• wherein
• when the first threshold is reached and the second threshold is not reached, the processor indicates the low battery state for the alarm,
• when the first and second thresholds are reached and the third threshold is not reached, the processor indicates the very low battery state for the alarm, and
• when the first, second, and third thresholds are reached, the processor indicates the depleted battery state for the alarm.
