 ABSTRACT This work provides an event-oriented method to model and predict the lifetime of leadacid and lithium-iron phosphate batteries. An ampere-hour integration method is proposed to be used in conjunction with the event-oriented method to achieve higher accuracy. The methods are applied to lead acid and lithium-iron phosphate batteries on a commercial 1 kW single-office/home-office uninterruptible power supply (UPS). Additional circuits for measurements, or microprocessors are avoided to not increase the UPS cost, reducing its market competitiveness. The usefulness of the proposed approach is demonstrated by an upkeep analysis based on the cost of the battery and the service time for each battery technology.
