Customer ServiceEV power battery testing has three main elements, namely SOC, SOH and battery life prediction. The relationship between capacity loss L cal per d, the SOC and the temperature of the battery is shown for different temperatures in Fig. 1.As the temperature increases, the SOC gradually increases at the same reaction rate.
Customer ServiceDuring the thermal test, batteries are placed in a testing chamber, and the temperature is raised at 5C per minute to a maximum of 130C. These tests reveal how the battery responds to different temperatures. During the temperature cycling test, the battery is placed in a chamber where the temperature is decreased from 85C to -40C at 1C per minute.
Battery testing methods range from basic voltage to more advanced methods like diagnostic battery management (dbm), which helps detect subtle battery issues that could go unnoticed. Different battery chemistries require unique battery testing methods, such as lithium-ion (li-ion), lead-acid, and nickel-based batteries.
As technology grows, batteries have become an integral part of our daily lives. They power everything from our smartphones to our vehicles, and even the renewable energy grid systems that are changing the way we use power. To ensure that these batteries deliver the expected results, we must regularly test and maintain them.
Batteries undergo both laboratory and field testing. Laboratory testing is designed to create controlled and repeatable environments that can precisely control aspects like temperature and humidity. On the other hand, field testing offers unpredictable conditions for batteries to reflect the scenarios consumers may be operating in.
Battery test standards, including by IEC, SAE, and UL, guide manufacturers at every stage of the design process. Various testing models exist to verify safe operation in real-world conditions for industries as diverse as automotive, aerospace, and health care.
In the case of a lead-antimony battery, measure and record the specific gravity of 10% of the cells and float charging current. For chemistries other than lead-antimony and where float current is not used to monitor the state of charge, measure and record the specific gravity 10% or more of the battery cells.
