This disclosure is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not just as admissions of prior art.
[0003] In the energy industry, energy storage plays a vital role, and batteries are a crucial component for storing energy. In recent years, lithium-ion batteries have gained popularity due to their high energy density, longer lifespan, and lower environmental impact as compared to lead-acid batteries. However, traditional inverters are not compatible with lithium-ion batteries as they are designed to work with lead-acid batteries. This creates a need for a method to replace lead-acid batteries with lithium-ion batteries in traditional inverters.
[0004] The challenges in this process are to modify the charging profile and low and high cut-off settings of traditional inverters that are not suitable for lithium-ion batteries. Additionally, it is necessary to obtain battery parameter data and create an in-built warranty without using a real-time clock (RTC) for reliability.
[0005] Furthermore, it is necessary for the user to view all the parameters of the inverter/UPS, such as battery charging, discharging, load time remaining, overload short circuit mains fail, etc.
[0006] Thus, there is a need for an easy and cost-effective method to upgrade to a more efficient battery technology in traditional inverters that addresses these challenges.
SUMMARY

[00042] The traditional inverters that have been in use for a long time typically utilize lead-acid batteries. However, with the advancement in technology, lithium batteries have become a popular and more efficient choice. The present disclosure proposes a method to replace lead-acid batteries with lithium batteries in traditional inverters.
[00043] One of the major challenges in this replacement is that the charging profile and low & high cut of normal inverters are different for lithium batteries. To overcome this challenge, a DC-to-DC converter is proposed. This converter takes input from any available inverter and controls the charging current and voltage according to the lithium battery. It regulates the low and high battery requirements and the charging current received by the inverter/UPS. If the charging current is higher than required, the converter will stop it.
[00044] In addition, an in-built warranty and an Internet of Things (IoT) device are included to get the data of battery parameters. Once installed, the device becomes Bluetooth/Wi-Fi enabled, and the user can see all the parameters of the Inverter/UPS like battery charging, discharging, load time remaining, overload short circuit mains failure, etc. This feature is advantageous to the customer.
[00045] If the user does not want to change the battery of the traditional inverter and has solar off-grid installed, then the proposed concept can be used as a charge controller and can be integrated with a new UPS/inverter. A universal serial bus (USB) is used to communicate with the new UPS installed with a lithium battery and with the charge controller. The UPS controller controls the charge sharing, where during the charging of the battery, the current is shared from the solar and mains, with prioritizing solar power. The Lithium battery is installed with the new UPS, and the rest of the parameters are taken care of by the DC-to-DC converter.
[00046] The proposed UPS with a lithium battery becomes off-grid as well as IoT device compatible. It can show all parameters of solar and UPS both in one IoT device through Bluetooth or Wi-Fi module. The method offers an advantage to the customer by providing an easy and cost-effective way to upgrade to more efficient battery technology in traditional inverters. It is an excellent solution for those who want to switch to lithium batteries but do not want to invest in a new inverter altogether.
[00047] The proposed method provides a simple and cost-effective solution for those looking to upgrade to more efficient battery technology. It also makes the UPS system IoT enabled, allowing the user to monitor and control their inverter remotely. With the increasing demand for efficient and sustainable energy solutions, this method provides a viable solution that is beneficial to both the customer and the environment.
[00048] Figures 1-3 illustrate a central processing unit, a solar PV voltage circuit, and another solar PV voltage circuit according to an embodiment of the invention. In modern power management systems, efficient utilization of battery resources is crucial for maintaining uninterrupted power supply and maximizing energy utilization. Traditional methods often lack adaptability and real-time monitoring capabilities, resulting in suboptimal performance and increased maintenance requirements. To address these challenges, a novel method for adaptive battery parameter management in inverter systems is presented, offering enhanced efficiency, reliability, and user convenience.
[00049] The proposed method begins with the detection of battery connection to the inverter system, as show in Figure 4. Upon detection (401), the method proceeds to obtain (402) the high and low requirements of the connected battery, essential for optimizing charging and discharging processes. Subsequently, the method calculates (403) the charging current received by the inverter, ensuring precise control over energy flow and battery health. Regulation (404) of both battery requirements and charging current is then performed to maintain optimal operation and prolong battery lifespan.
[00050] A key feature of the proposed invention is the integration of an in-built warranty and IoT device within the inverter system. This allows for seamless collection of battery parameter data, enabling real-time monitoring and analysis. Users gain comprehensive insights into battery performance, facilitating proactive maintenance and fault detection. Furthermore, the method utilizes a universal serial bus (USB) for efficient communication between components, simplifying system integration and data exchange.
[00051] Moreover, the proposed invention optimizes charge sharing between solar and main power sources, prioritizing renewable energy utilization. This ensures efficient energy management and reduces reliance on conventional power grids. Additionally, the integration of lithium batteries enhances system efficiency and compatibility with IoT devices. Users can conveniently monitor all parameters through a single IoT device, eliminating the need for separate monitoring systems.
[00052] Figures 5-6 illustrate a power section circuit of the converter according to an embodiment of the invention. Further, Figures 7-10 illustrate a reset circuit, a boost voltage circuit, a temperature sensor circuit, and a battery selection setting according to an embodiment of the invention.
[00053] The adaptive battery parameter method presented herein revolutionizes inverter system management, offering unprecedented efficiency, reliability, and user convenience. By harnessing the power of IoT technology and lithium batteries, the proposed invention sets new standards for energy management in both residential and commercial settings. The proposed method represents a significant advancement in the field of power electronics and warrants protection through patent application.
