Abstract: A reserve, energy sourced, or deferred action battery in which each battery cell is provided a separate reservoir containing the necessary electrolyte fluid for that cell. A simple design is then possible as the electrolyte fluid is stored in close proximity to the battery cells when needed at the time of activating the battery. A combination of two electrolyte fluids may be used that react exothermically when mixed together at the time of activation thereby producing heat. The production of heat allows the battery to activate at existing cold ambient temperatures that would otherwise render the reserve battery without sufficient operating power. The invention also provides an activation system which ensures reliable activation of the battery and ensures that the battery is not is subject to unintended activation.

Abstract: An electronic control system for a reserve, energy sourced, or deferred action battery that determines start-up temperature and voltage conditions to determine the necessary amount of charge to deliver from a reserve battery to a discharged battery. A temperature sensor is used to measure the ambient temperature and operating temperature of the electronic control system. A target charge value is selected based on the ambient temperature and startup voltage information. The operating temperature of the electronics control system is monitored to ensure the most efficient and reliable delivery of charge. Indications are provided to the user to provide information regarding charging status, connection status, and voltage levels.
