Factors such as method, temperature, DOD, load, and duty cycle are considered. For example, battery capacity and cycle life, two key performance indicators, can vary by 50 percent or more depending on the temperature and discharge rate at the time of testing. Battery specifications should always include test conditions to avoid ambiguity.
A solid battery testing procedure can help monitor battery health, predict its performance characteristics, such as cycle life and state-of-health, and diagnose any potential issues that may cause battery failure. Consequently, this helps to prevent breakdowns, keep battery capacity in good condition, and keep the charge efficiency at a maximum.
One key factor that determines a battery’s prowess is its capacity. In this guide, we will delve into the intricate world of battery capacity testing, unraveling the mysteries behind this crucial aspect of battery performance.
When testing a battery, three SoH indicators must be evaluated: Batteries come in many conditions and a charge can easily mask a symptom allowing a weak battery to perform well. Likewise, a strong battery with low charge shares similarities with a pack that exhibits capacity loss.
“Battery testing” can range from the characterization of the smallest batteries in portable equipment to large vehicle batteries operating at 1,000 V and beyond. Battery systems are critical to electric vehicles. Today, lithium-ion batteries are one of the most commonly used types in electric vehicles due to their high energy and power density.
Well-developed battery test technologies must recognize all battery conditions and provide reliable results, even if the charge is low. This is a demanding request as a good battery that is only partially charged behaves in a similar way to a faded pack that is fully charged.
