How Does a 6-Channel Pouch Cell Tester Work?

Today in the fast-paced energy storage market, everything is powered by lithium, from your smartphone to electric vehicles. Enabling the efficient and safe progress of these technologies are cutting-edge testing and sorting devices, in particular, the 6-channel pouch cell tester. In this article we take a closer look at the role of this new exciting power tool of battery testing, how it works, and why it is essential in the battery manufacture operation.
What Is A Pouch Cell Tester?
Pouch-cell testers are simply testing devices that define the quality and confirm that pouch-type lithium-ion batteries meet requirements. While cylindrical or prismatic cells come in a ridged metal casing, pouch cells come in an aluminum casing that is pliable, hence light and compact. You will find pouch cells in electric vehicles (EVs), energy storage systems (ESS), and portable electronic devices.
Meanwhile, every 6-channel pouch cell tester is a testing system that tests 6 separate pouch cells simultaneously. Every channel in the pouch cell tester is independent so that battery manufacturers can check the performance of multiple cells at the same time. The multi-channel trait makes for quicker testing and speeds the entire process up, greatly increasing throughput on busy production floors.
Key Functions of a 6-channel Pouch Cell Tester
Voltage and Capacity Testing: The tester checks voltage and capacity of every single cell. The level of voltage essentially tells you how charged the battery is, while the capacity testing ascertain that in a full charge cycle the battery can store the required charge for optimum performance.Internal Resistance Measurement: To ascertain a battery’s state of health, internal resistance is crucial. Essence: A Battery’s Internal Health
Excessive Resistance: Resistance to the passage of current can result in loss by heat and energy, permitting overheating, and possibly destroying battery life. The tester can see if trouble could arise, due to design, or construction of the cell.
Charge and Discharge Cycles: To nip real-life operational demands in the bud, the tester performs artificial cycles of charge and discharge to see how well the battery copes with this operational burden—and thus can tell manufacturers where cell design is lacking.
Overcharge and Overdischarge Protection: The 6-channel tester is also conscious overcharge and overdischarge states, showing that the battery can be charged to all states without fear and used in all states of charge as well (overcharge may indicate causes of a runaway condition, for example).
Cycle Life Testing: The tester performs charge and discharge cycles, and counts how many of these cycles the pouch cell will take, before the capacity enters the dead zone, a key number for EVs.
Temperature Sensing: Due to the deleterious effect certain heat imperatives have, temperature sensing is prevalent in testers; excess heat may indicate the quality of a cell, or manufacturing problem.
Any Downsides?Pluses of the 6-Channel Pouch Cell Tester
Faster throughput: “We get more than two hours back into production process if 30 seconds of testing is removed from each cell,” said Keller.
Groundbreaking: Tests Multiple Cells at Once “Most traditional battery testing is done one cell at a time,” notes Keller. “And with limited time and assets to dedicate to each cell, this is not the most effective method. By testing several cells at once to ensure they meet or exceed specifications, you will save money.”
More info: “The six-channel pouch cell tester allows for testing of multiple cell sizes and capacities at one time,” Keller continued.
“It makes testing time shorter, allowing more cells to be tested in less time and resulting in more accurate information.” Keller continued, “As a review, if I know that I tested a thousand times with zero flaws, the test would take less than a day and allow me to save thirty seconds total testing.”
