Development of a Charge Algorithm for the Optimized Charging of a 120 V Flooded Lead-Acid Lighthouse Battery with Forced Electrolyte Destratification.

摘要

Proper charging was identified as the most important requirement for the reliable and economical operation of a battery that is part of the hybrid power system for remote lighthouses. Therefore a charge algorithm was developed to optimize charging of a flooded lead-acid battery with forced electrolyte destratification. This algorithm is independent of the operating temperature, the state of charge and the battery age. It controls charging according to the weakest battery module in the pack and is able in the course of several cycles to automatically equalize the performance of the modules in the battery pack without excessive overcharging. The charge algorithm prevents overheating due to bad battery connectors and quite generally responds to all causes of poor charge acceptance with a gentle treatment of the battery during charging.
