The present invention generally relates to a thermal battery testing apparatus and a method for testing a thermal battery. The method includes one or more of the following steps: connecting the thermal battery in series with a resistance; connecting the thermal battery and resistance in series with a sinusoidal voltage source; applying a sinusoidal voltage to the thermal battery, measuring an impedance, reactance and/or capacitance across two terminals of the thermal battery, comparing the measured impedance, reactance and/or capacitance to a reference impedance, reactance and/or capacitance; and indicating whether the tested thermal battery is 'in family' or 'out of family.' The battery testing apparatus may include a testing device configured to apply a sinusoidal voltage to the thermal battery and to measure the impedance, reactance and/or capacitance across two terminals of the thermal battery. The testing apparatus may further be configured to report &#x201c;out of family&#x201d; batteries.

System and method for nondestructive testing of thermal batteries

A method of manufacturing thermal batteries is disclosed. In the method according to the present invention, pellets used in the manufacture of thermal batteries are grouped together based on certain material characteristics such as weight, thickness, and density. Pellets with different material characteristics can be grouped together in a single thermal battery to produce a thermal battery with characteristics that are the average of the characteristics of the pellets used to manufacture the thermal battery.

System and method for manufacturing a thermal battery

The present invention is directed at a system for automatically manufacturing thermal batteries. In the present invention, thermal batteries are manufactured using a press system, a stacking system and an enclosing system. The present invention uses a tracking, storage, and/or retrieval system to track various components used in the manufacturing process to improve manufacturing quality and to track the various components throughout the manufacturing process.

Automated tracking and storage system for use with an automated thermal battery manufacturing system

An automated system and method for manufacturing a thermal battery is disclosed. In an exemplary embodiment, the system comprises a press system, a stacking system, and an enclosing system to automate the manufacturing process of thermal batteries. A method of manufacturing a thermal battery using the system is also disclosed. An automated tracking, storage, and retrieval system for pellets used in the manufacturing process and a pellet pairing system are also disclosed.
