DESC:TECHNICAL FIELD
[0001] The present disclosure relates to the field of a regenerative battery tester and, more particularly relates to a regenerative battery tester on which one can check the battery by charging and discharging the battery.
BACKGROUND
[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described below. 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] Battery life testers are devices that evaluate the performance and capacity of batteries. They do this by subjecting the battery to a series of charge and discharge cycles and measuring the battery’s voltage and current. The results of these tests are used to determine the battery’s capacity and efficiency. One aspect of battery performance that can be evaluated using a battery life tester is the battery’s capacity, typically expressed in amp-hours (Ah) or milliampere-hours (mAh). A battery with a high capacity can store more energy and power a device for a longer period before needing to be recharged.
[0004] In addition to capacity, battery life testers can also evaluate a battery’s efficiency, or how well it converts chemical energy into electrical energy. A battery with high efficiency can deliver more power to a device for a given amount of energy input.
[0005] There are a variety of different battery life testers on the market, each with its own set of features and capabilities. Some testers are designed for use in laboratory settings, where they can be used to conduct more controlled and precise testing. Other testers are designed for use in the field, where they can be used to evaluate the performance of batteries in real-world conditions.
[0006] Regardless of the specific type of tester being used, the goal of battery life testing is to gather as much information as possible about the battery’s performance. This information can be used to improve the battery’s design, to optimize its use in a particular application, or to compare it to other batteries on the market. Ultimately, the goal of battery life testing is to help ensure that batteries are able to deliver reliable and consistent performance over their lifetime.
[0007] One type of battery life tester that has gained attention in recent years is the regenerative battery life tester, which faces a technical problem with power wastage. This occurs because some of the excess energy is dissipated as heat rather than being put to use. There are a few potential causes of this problem, such as the tester’s energy capture and return system being inefficient. To address this issue, it is necessary to optimize the design of the battery tester or the tester’s energy capture and return system.
SUMMARY
[0008] The present disclosure relates to a regenerative battery life tester. The tester is designed to minimize energy waste by returning any excess energy that is generated during the testing process back to the grid. In other words, rather than simply dissipating the excess energy as heat, a regenerative battery life tester captures it and feeds it back into the electrical grid.
[0009] In an embodiment, the regenerative battery life tester includes an inverter with a charger, which is used to charge the battery to a predefined voltage. Charging the battery to a predefined voltage comprises the tester automatically begins discharging the battery at a predefined current once the battery is charged to this level.
[00010] In another embodiment, the predefined current is selected by a user through a software dashboard.
[00011] In an embodiment, the regenerative battery life tester is a 48V regenerative battery life tester.
[00012] In another embodiment, the load is fed into the grid while the battery is being discharged, allowing the tester to capture any excess energy that is generated and return it to the grid.
[00013] In another embodiment, the tester also provides the voltage and current curve of the battery while it is being charged and discharged.
[00014] In another embodiment, providing the voltage and current curve of the battery comprises storing by the tester the individual voltages of each cell online and providing a graph that shows how all of the cells are behaving.
[00015] In another embodiment, the tester also includes a setting for low battery. When this setting is activated, the tester will automatically start charging the battery again when the battery’s voltage drops to a certain level. This allows users to see the full spectrum of the battery’s performance, from low voltage to high voltage.
[00016] In another embodiment, the tester also provides the option to discharge the battery at different selected currents, which can be useful for testing the battery under different conditions.
[00017] In another embodiment, the tester also includes a provision for connecting external loads. This allows users to put a particular load on the system and run it while discharging the battery.
[00018] In another embodiment, the tester also includes the option to connect an AC load, which can be used to power household or office equipment.
[00019] In another embodiment, the tester also includes a time-based switching feature, which allows users to turn the load on and off on the mains line. When the load is switched from the mains to the battery, the tester is able to make the transition in less than 10 milliseconds, ensuring that there is no disruption to the running load.
[00020] Overall, the regenerative battery life testers offer several advantages over traditional testers. They minimize energy waste by returning excess energy generated during the testing process back to the grid, making them more energy efficient and environmentally friendly. They also eliminate the need for external circuitry, streamlining the testing process and reducing the cost of equipment. These benefits make regenerative battery life testers more efficient and cost-effective.
[00021] The above advantages of the present disclosure will become more apparent when reference is made to the following description.

[00028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The apparatus, system, and examples provided herein are illustrative only and not intended to be limiting.
[00029] The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. Further, the term sterile barrier and sterile adapter denotes the same meaning and may be used interchangeably throughout the description.
[00030] The present disclosure mentions a regenerative battery life tester which is specifically designed to minimize energy waste during the testing process. Traditional battery life testers simply dissipate excess energy as heat, which is not only wasteful but also inefficient. In contrast, the regenerative battery life tester described in this disclosure captures this excess energy and returns it back to the grid, ensuring that all of the energy taken from the grid is put to good use.
[00031] The regenerative battery life tester includes an inverter with a charger, which is used to charge the battery to a predefined voltage. Once the battery is charged to this level, the tester automatically begins discharging the battery at a predefined current, which can be selected by the user through a software dashboard. While the battery is being discharged, the load is fed into the grid, allowing the tester to capture any excess energy that is generated and return it to the grid. This process minimizes energy waste and ensures that all of the energy taken from the grid is utilized effectively. Optionally, the regenerative battery life tester is a 48V regenerative battery life tester. Optionally, the grid is feed with an energy from the solar panels via MPPT charger.
[00032] One key advantage of the regenerative battery life tester is its ability to provide more accurate and reliable testing. By eliminating the impact of external factors on the testing process, the tester is able to provide a more consistent and accurate evaluation of the battery’s performance. In addition, by returning excess energy back to the grid, the tester is able to ensure that all of the energy taken from the grid is put to good use, rather than being wasted. This can be especially beneficial in situations where energy is scarce or expensive, as it can help to reduce the overall energy footprint of the testing process.
[00033] Another advantage of the regenerative battery life tester is its efficiency and cost-effectiveness. By minimizing energy waste and eliminating the need for external circuitry, the tester is able to streamline the testing process and reduce the cost of equipment.
[00034] In one of the embodiment, the tester provides the voltage and current curve of the battery while it is being charged and discharged. To do this, the tester stores the individual voltages of each cell online and provides a graph that shows how all of the cells are behaving. This can be useful for identifying any issues with the battery or for optimizing its performance.
[00035] In addition to its standard testing capabilities, the tester also includes a setting for low battery. When this setting is activated, the tester will automatically start charging the battery again when the battery’s voltage drops to a certain level. This allows users to see the full spectrum of the battery’s performance, from low voltage to high voltage. The tester also provides the option to discharge the battery at different selected currents, which can be useful for testing the battery under different conditions.
[00036] In an embodiment, the tester also includes a provision for connecting external loads. This allows users to put a particular load on the system and run it while discharging the battery. However, due to the maximum capacity of the system (30 or 40 amps), the load may not be able to reach its standard level. To address this, the tester includes the option to connect an AC load, which can be used to power household or office equipment. The tester also includes a time-based switching feature, which allows users to turn the load on and off on the mains line. When the load is switched from the mains to the battery, the tester is able to make the transition in less than 10 milliseconds, ensuring that there is no disruption to the running load.
[00037] The unreliability of backup estimates in existing battery testing methods has become a prominent issue in the industry. These inaccuracies lead to customer dissatisfaction and potential warranty concerns. The lack of proven quality testing makes it challenging for distributors to confidently stand behind the batteries they sell, leaving service engineers without concrete evidence when troubleshooting battery-related problems. Furthermore, customers face purchase confusion as they struggle to identify the true backup capabilities of batteries, making it difficult to choose the right one for their specific needs.
[00038] As shown in Figure 1a-b, relying on internal resistance (IR) and meter readings for battery life assessment introduces significant inaccuracies. Internal Resistance, while commonly used, presents challenges due to its non-linear relationship with the battery's discharge state and the influence of external factors such as temperature, discharge rate, and battery age. Meter readings, obtained through tools like multimeters and clamp meters, offer only rough estimates and may lack calibration for specific battery types. Dedicated IR meters, though more accurate, vary in quality and calibration, contributing to inconsistencies due to the absence of industry standards for battery testing equipment.
[00039] These readings provide indicative life rather than precise backup time due to the dynamic nature of battery discharge. Factors like discharge rate, load characteristics, and environmental conditions significantly impact actual backup time, hindering accurate predictions based solely on IR readings.
[00040] Meter quality and availability further compound the issue. Non-standard or poorly calibrated meters contribute to inaccurate readings, while high-quality IR meters may not be readily accessible or affordable for all users. Relying solely on internal resistance and meter readings is deemed unreliable, providing only indicative values that should not be considered definitive predictors of backup time.
[00041] In response to these challenges, Figure 2a-d shows a regenerative battery life tester or battery Power Backup Time Tester which emerges as a precise and portable solution that accurately measures the true backup time of batteries, irrespective of size or type. The device simulates real-world conditions by drawing power from the battery and measuring how long it can sustain specific loads.
[00042] The Battery Power Backup Time Tester offers numerous benefits for distributors, allowing them to boost customer confidence by providing accurate backup time data, optimize inventory by identifying batteries with exceptional backup times, and simplify warranty claims with concrete evidence supporting decisions.
[00043] Service engineers also benefit from the tester by quickly diagnosing battery issues, reducing service costs, and improving customer satisfaction through clear and reliable information about battery performance.
[00044] The Battery Power Backup Time Tester represents a game-changer for the battery industry, empowering distributors and service engineers to make informed decisions, prove quality, and deliver exceptional customer service. The call to action urges businesses to invest in the future of battery testing by contacting the provider to learn more about the Battery Power Backup Time Tester and its potential to revolutionize their operations.
[00045] Additional features, such as an easy-to-use interface, data logging, reporting for detailed analysis, and compatibility with a wide range of battery types and sizes, further enhance the appeal of the Battery Power Backup Time Tester. The conclusion emphasizes the importance of taking control of battery testing and encourages prompt action to experience the power of accurate and reliable data by acquiring the Battery Power Backup Time Tester.
[00046] Functionality of Automatic Battery Tester: The Automatic Battery Tester (ABT) is designed to seamlessly conduct a backup time test for 12-volt Lead Acid batteries, encompassing Tubular, VRLA, Gel, or any Lead Acid battery within the 100-250 Ah capacity range. The ABT employs a sophisticated charging process, utilizing Boost mode to charge the battery up to 14.4 Volts, followed by Float mode, stabilizing the battery at approximately 13.6 Volts to ensure proper battery gravity. The four-stage charging system includes Boost, Absorption, Float, and Trickle charging, taking 14 to 15 hours for thorough charging. This meticulous charging process is crucial for accurate backup time testing, considering the Lead Acid battery charging standard of 10% of its capacity. Thus, the charger is meticulously designed to meet this requirement.
[00047] Automatic Transfer: Upon completion of the charging process, the ABT seamlessly transitions to battery backup mode. If a load is connected, the ABT automatically initiates the battery discharge process, which continues until the Low Battery sign is triggered at the preset voltage of 10.5 Volts.
[00048] Life Cycle Test: The user defines the testing process, specifying the connected load through the hardware switch on the ABT. A DSP-based controller system oversees the charging and discharging processes through the hardware switch. Voltage and current sensors closely monitor battery parameters throughout the cycle. The DSP-based ABT records essential data, including time, voltage, current, and cycle count. The life cycle test persists until a predefined number of cycles is reached or a battery failure criterion is met. The collected life cycle data is then analyzed and presented for comprehensive evaluation.
[00049] Life cycle data is analyzed and presented for evaluation. Features of the Automatic Battery Tester, DSP-based Bidirectional Technology: The DSP-based ABT employs bidirectional technology to record time and voltage at regular intervals, along with other parameters such as power consumption during charging and discharging processes.
[00050] Isolation Transformer: Figure It's worth noting that High-Frequency-based Charger-Dischargers can be sensitive to voltage variations and power surges, posing challenges in developing countries. In contrast, the Isolation-based ABT utilizes a stable technology with rare failures and a life expectancy of a minimum of 15 years, easily repairable by local technicians. Isolation, or galvanic isolation, ensures no direct path for current flow, and an isolation transformer enhances stability by providing isolation between electrical devices and their power source.
[00051] Features of Automatic Battery Tester: Digital Warranty: introduces a revolutionary Digital Warranty system, displayed on a computer screen. The warranty gradually reduces over time as the ABT is utilized, offering a 2-Year Digital Warranty. The Su-vastika Pure SinewaveK Battery Tester is Bluetooth and WiFi compatible, paving the way for future upgrades to a dedicated Bluetooth application or Wi-Fi-based remote real-time monitoring.
[00052] Additional Features: The ABT boasts a user-friendly interface for setting test parameters and viewing results. Data logging in computer-based software continues in the background during the test. A communication interface facilitates remote monitoring and data transfer, while an alarm functionality promptly notifies users of potential battery issues.
[00053] Overall, the aspects of the present disclosure provide more efficient use of energy, rather than wasting energy during the testing process, a regenerative battery life tester ensures that all of the energy that is taken from the grid is put to good use. This can help to reduce the overall energy footprint of the testing process, making it more sustainable and environmentally friendly.
[0001] Another advantage of regenerative battery life testers is that they do not require any external circuitry. In traditional battery life testers, it is necessary to use external circuitry to control the charging and discharging of the battery. This can add complexity to the testing process, as well as increase the cost of the equipment. By eliminating the need for external circuitry, regenerative battery life testers are able to streamline the testing process and reduce the cost of equipment.
[0002] Overall, regenerative battery life testers offer a number of benefits over traditional battery life testers. By minimizing energy waste and eliminating the need for external circuitry, these devices are able to provide more efficient and cost-effective testing of batteries. As such, they are likely to become increasingly popular in the coming years as demand for energy-efficient technologies continues to grow.
