Title:
LEAD STORAGE BATTERY AND LEAD STORAGE BATTERY SYSTEM FOR SYSTEM UTILISING NATURAL ENERGY
Document Type and Number:
WIPO Patent Application WO/2012/020575
Kind Code:
A1
Abstract:
A lead storage battery or lead storage battery system for a system utilising natural energy, wherein the purpose of the present invention is to provide a novel lead storage battery or lead storage battery system which is superior in terms of costs as the power and costs required for uniform charging and the number of times the natural energy/storage battery system stops are reduced by varying the uniform charging interval of the lead storage battery in accordance with the usage conditions (SOC transition) of the lead storage battery to thereby prolong the life of the lead storage battery, and by reducing the uniform charging performed only to ascertain the SOC. A further purpose is to provide a lead storage battery and a lead storage battery system in which operation is easy to manage as a result of it being made possible for the user of the lead storage battery to ascertain the timing of the next scheduled uniform charging. The lead storage battery and lead storage battery system is provided with: an SOC transition history management unit that obtains an estimated SOC transition condition; a lead storage battery deterioration model; and a uniform charging optimisation planning unit that plans a system for implementing an optimum lead storage battery, on the basis of the information of the deterioration model and the SOC transition condition from the SOC transition history management unit.
