Introduction to the charging efficiency in the charge and discharge process of lithium-ion battery packs.
This document introduces the measurement of heat generation during charging and discharging of a Battery Pack with a capacity of 350mAh (3.7V) and dimensions of 40mm × 29mm with a thickness of 4.5mm. The battery is unused but is an old one manufactured on July 11, 2006, which is over 10 years old. Our company can manufacture heat flow detection modules according to the battery size. In this technical document, the heat flow detection module is set up in a room temperature environment, using the HJ1001SD8 (Hokuto Denko) as the charging and discharging device. 【Features】 ■ Capable of manufacturing heat flow detection modules according to battery size ■ Heat flow detection module set in a room temperature environment ■ HJ1001SD8 (Hokuto Denko) used as the charging and discharging device *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company works in the field of thermal safety evaluation to prevent thermal runaway accidents involving chemical substances. To achieve this, we analyze reaction kinetics parameters from thermal measurement data of a few milligrams of chemical substances and provide a measurement and analysis system that enables thermal safety evaluation when the chemical substances are scaled up to kg to 1000 kg. Additionally, we offer an evaluation system that combines isothermal microcalorimeters (IMC) for lithium-ion batteries and DSC with AKTS analysis software, allowing for comprehensive measurement of the entire battery.
