Retaining the Power Backup of the Battery and Increased Life Span of the Battery for the Solar System- Challenges and Opportunities

Abstract

The battery backup plays an important role in storing energy from the solar panel during the daytime. This energy, thus, stored can be utilized for daily usage during day and night. Depending on the amount of power generated from the solar panel the battery bank must be selected. The lifespan of the battery depends on the charging and discharging cycles. The life span also depends on the amount of load connected to the battery as well as the rate at which the current is drained from the battery. It’s critical to note the charging and discharging cycles of the battery must be reduced to improve the life span of the same. This paper explains the different types of batteries and the factors affecting the life span of batteries. The paper also suggests the methods to be followed to improve the life span by proposing a model for charging. This model regulates the charging and discharging cycle of a battery to increase the life span of the battery. The model also regulates the charging current by considering the battery temperature. The raise in battery temperature also reduces battery life. The paper performs the ABCD analysis of the new model considering the various issues related to battery performance and socio economic impacts of the same. This paper concludes with the recommendation to implement the charger for the battery-operated devices that do not require fast charging, thus, improving battery life. This paper also concludes with the statement that the proposed model is not suitable for any battery operated devices, which require fast charging where improved battery life is not so essential.
