What is battery discharge testing?

Battery discharge testing, also known as battery load testing, is a process that test battery health statement by constant current discharging of the set value by continuously the discharge current from a fully charged state and then measuring how long the battery lasts.

How to measure battery self-discharge?

A powerful tool is presented to directly measure battery self-discharge. Precise self-discharge currents are measured with a high resolution of 0.25 µA. Experimental investigation of the method is done based on temperature and SoC. Arrhenius analysis of self-discharge provides chemical insights to the LiB cells.

How does lithium ion self discharge measure a cell's self-discharge?

These Lithium-ion self discharge measurement solutions determine a cell’s self-discharge by directly measuring its self-discharge current. Directly measure self-discharge current in as little as 1–2 hours instead of monitoring cell open circuit voltage over days or weeks.

What happens if a battery has a different self-discharge rate?

Varying self-discharge rates between cells in a battery pack can result in voltage imbalances between the cells and a shorter battery pack life (Zheng et al., 2020). Self-discharge rates vary depending on the cell chemistry, capacity, electrode geometry, electrolyte formulation, impurities, and temperature.

What is intelligent battery discharger?

Intelligent battery discharger is a instrument that can maintain and capacity test to battery, DC power and UPS backup battery.
