Features of an Intelligent Battery Test System

Battery performance and safety are key in determining the reliability in applications such as new energy vehicles (NEVs), energy storage systems (ESS), and industrial mobility equipment. With the new energy industry continuously evolving, battery performance and safety are crucial. As a national high-tech enterprise specializing in new energy battery electrical performance testing, Zhuhai Jiuyuan Power Electronics Technology Co., Ltd. has developed a series of intelligent battery tester solutions that integrate precision, efficiency, intelligence, and flexibility. These solutions address the core testing needs. Global customers in the battery industry rely on Jiuyuan Power Technology. Below, we describe the key features and intelligent battery testing systems that keep Zhuhai Jiuyuan ahead of the competition.

High Accuracy of Electrical Performance Detection

The key value of an intelligent battery tester is its ability to offer accurate and reliable test and measurement data, and in this regard, Zhuhai Jiuyuan is recognized as an industry leader. Its test systems are characterized by the industry-leader of ±0.1% V on voltage measurement, and ±0.001 Hz on frequency control, an achievement that even falls short of the national standards’ most basic level for battery testing. With these metrics, each crucial parameter of a battery—its capacity, charge-discharge efficiency, internal resistance, voltage stability during cycling, and the like—will measure with sufficiently small deviations to infringe the battery testing system.

Users have the opportunity to collect and analyze specific data to comprehend the actual functionality of the battery. For example, when assessing the capacity over time of lithium-ion batteries used in New Energy vehicles (NEVs), the system can detect very small differences in the rate of capacity decline between individual cells, allowing manufacturers to eliminate bad cells and improve the balance of battery packs. Similarly, the internal resistance of lead-acid batteries used in backup power systems can give indications of aging within the battery system and help to prevent the batteries from going into an unexpected power outage. Zhuhai Jiuyuan produces intelligent battery testers that have consistency and reliability to obtain test results in all technologies including lithium-ion and lead-acid (as well as special designs with electrolytes), providing a strong basis for quality assurance and continued efforts for improvement within product development.

Bidirectional Energy Flow & Energy-Efficient Design

With traditional battery test equipment, users are faced with increased energy costs from the wasted electricity, as well as the added operational complexity associated with the need for supplementary cooling systems. Discharge testing on these systems uses resistive loads which converts the electricity into heat and therefore, wastes energy. With a bidirectional energy flow, Zhuhai Jiuyuan’s Intelligent battery test system can overcome this design challenge.

The system can do both unidirectional and bidirectional load testing. It can simulate real-world charging scenarios, during charging test. It can control charging current and voltage precisely. For discharge test, rather than wasting the energy through resistors, the system either feeds the discharged electrical energy back to the grid or stores it in an energy storage system to be used later. By keeping resistive load power consumption to nil, a comprehensive energy efficiency of up to 98.5\% can be achieved as power consumption by the system is also kept to a minimum.

This energy-saving constituent of the system is also beneficial to users performing extensive testing, such as battery manufacturers with mass production lines or energy storage companies undertaking long cycle tests. For instance, a battery production line in which 10 test stations are operating can save electricity by thousands of yuan on an annual basis compared to traditional equipment. The system also saves on carbon emissions, thus contributing to the worldwide green development.

Intelligent Data Analysis & Safety Precaution Systems

Advanced intelligent battery testers are designed to perform predictive battery testing and risk assessment in systems. The test systems from Zhuhai Jiuyuan integrate predictive intelligent data analysis algorithms with safety risk systems to transform test data from a passive to a proactive system.

While testing the system individually analyzes the voltage, temperature, and internal resistance and charge-discharge rate. If the system records unusual values, such as a rapid increase in internal resistance indicating micro-short circuits, or a steep localized increase in temperature suggesting thermal runaway risks, the system starts a warning alarm and sends a warning message. This warning system has the potential to inform users of incidents that threaten the safety of the system, such as combustion or explosion of a battery. This monitoring and warning functionality is especially important when testing large scale energy storage batteries.\n\ Long term analysis of the collected data is the other functionality of the system. Studying the cycle life data of a set of energy storage batteries enables the system to predict the remaining number of charge-discharge cycles the batteries can undergo. This information is valuable in maintaining and even replacing batteries in a system and preventing dropout on the end user’s side. Battery management and predicted cycle life data may yield maintenance programs for the end users.

Flexible Customization for Multi-Scenario Adaptation

The battery industry spans many application scenarios, with power battery, energy storage battery for grid-scale ESS, and aerospace specialty batteries all requiring vastly different types of testing. A one-size-fits-all testing system will never be able to satisfy all customers, and this is where customization capabilities come into play.

Zhuhai Jiuyuan’s R&D staff, having vast expertise within the new energy industry, are able to provide customized intelligent battery tester systems to meet each customer’s needs.

For battery pack manufacturers: Include battery charge/discharge cycle testing to mimic fast charge/discharge scenarios battery utilized in electric vehicles, and long duration tests to assess battery performance at low temperatures to simulate cold weather regions.

For energy storage systems: Adapt the system's power range and duration of the tests to adequately perform long cycle testing simulations over battery pack of large capacity, in energy storage systems.

For aerospace or other extreme environments: The systems structural design should be optimized with regards to the environmental parameters, for maximum flexibility at high altitudes or extreme temperatures.

Such flexible customizations will ensure the test system is in complete alignment with the user's application scenarios as well as avoiding spending on unnecessary functions, achieving cost savings through meeting the testing needs at the same time.

Consistent Value from Dependable Design

Testing batteries is a long process. At times, it requires batt testers to run continuously. This is the case in manufacturing and quality inspection. Because of this, the continuity of work is very reliant on the intelligent battery tester.
