Advance EV Battery Cell Development

Advance electric vehicle (EV) Battery Cell Development

The electric vehicle (EV) battery is one of the most expensive components of the modern EV. Ensuring the battery pack delivers peak performance starts at the cell level, since the weakest cell will degrade the performance of the entire battery at the module and pack level.

At the R&D stage, developers in an EV battery cell test lab often have to handle thousands of test channels. They must characterize, select, and optimize both cell chemistry and material. Precise characterization of cells must also be done to determine internal resistance, efficiency, capacity, cyclical life span and calendar life, as well as reaction to temperature changes, and mechanical resistance, among other test parameters. In addition, impedance testing of battery cells can provide early warning of potential cell weakness or abnormal deterioration which can lead to battery failure.

Understanding Measurement Accuracy Specifications for Battery Testers

Understanding Measurement Accuracy Specifications for Battery Testers

When you specify and purchase cell and battery test equipment for your R&D lab or production line, it is critical to have a thorough understanding of performance specifications. While it may be easy to state the price, the number of channels you need, and the current per channel, the accuracy of the equipment is the most critical specification. It can be challenging to specify your needs correctly. In this white paper, you will learn how to define accuracy and error in the realm of test equipment, four ways to specify accuracy, and interpret an actual error versus a specified error.
