Embodiment Construction

[0052] Reference is now made in detail to certain embodiments of the calorimeter. The disclosed embodiments are not intended to be limitations of the claims. On the contrary, the claims are intended to cover all alternatives, modifications and equivalents.

[0053] In its various aspects, the disclosure describes a calorimeter and methods for making and using the same. The calorimeter described here helps manufacturers understand the thermal operating characteristics of an electronic device or battery by measuring the heat generated when the battery is charged or discharged, or when the device is operated, whether the heat is electrochemically or resistively generated, etc. Also the calorimeters described herein can be operated over a wide range of test temperatures and conditions, and thus are capable of measuring the thermal operating characteristics of electronic devices and batteries at a number of different temperatures. Knowing the thermal operating characteristics of ...
