At least a portion of the enclosure of a thermal battery is formed of a ceramic material that is non-porous and electrically-non-conductive. The thermal battery includes at least one cell, a squib that when activated causes the at least one cell to become active, and an enclosure that surrounds the at least one cell and the squib. Squib terminals and battery terminals extend through the enclosure and are electrically connected to the squib and to the at least one cell, respectively. At least the portion of the enclosure through which the squib and battery terminals extend is formed of the ceramic material. The enclosure includes a container and a header. At least the header is made from the ceramic material, and preferably both the container and the header are made from the ceramic material.

Ceramic enclosed thermal battery

A power supply apparatus has at least one modular reserve battery magazine with a plurality of compartments. A plurality of reserve battery modules may be respectively replaceably provided in corresponding ones of the plurality of compartments, each of the plurality of reserve battery modules being configured to provide power when a reserve battery provided therein is activated. Each reserve battery module of the plurality of reserve battery modules includes a sleeve and a reserve battery provided within the sleeve, the sleeve being configured to fit within one of the plurality of compartments in a predetermined orientation. Each sleeve may be detachably connectable within any compartment of the plurality of compartments and includes electrical connections so that each reserve battery module of the plurality of reserve battery modules is separately replaceable while the power supply apparatus remains remotely located.

Power supply apparatus with reserve battery modules and method for providing backup power

A subsea system includes an electrically powered control system for controlling the subsea system and a replaceable reserve battery electrically coupled to the control system to provide backup and/or supplemental power to the control system when the reserve battery is activated. The reserve battery is provided in a housing having a first coupling, the subsea system includes a second coupling, and the first and second couplings are detachably connectable to each other and include electrical connections so that the reserve battery is replaceable while the subsea system remains below the sea-surface.
