Evaluation testing of lithium ion batteries

In the evaluation of the electrical properties of lithium ion batteries, it is necessary to measure the voltage with high accuracy to prevent overcharging. The high-speed, high-voltage measurement unit in the NR Series multi-input data logger has a 14-bit resolution and a sampling cycle of 1 MHz, so this unit can support testing that requires high precision. Also, by using a temperature sensor, you can simultaneously record, for example, abnormal heat generation or overcharging of batteries. This allows you to complete the evaluation of lithium ion batteries using only a single unit.
