This article by Paladugu Chandrasekhar (CEO, Futurelite Batteries) discusses the tests involved in assembling Lithium-ion cells into modules and battery packs. Machine needed – Individual Cell Capacity testing Machine Formation – The cells received by the pack manufacturing unit could be at different levels of charge.
Checking the health of a lithium battery with a multimeter is essential for anyone working with or relying on lithium-ion batteries. This includes an initial voltage check after charging, investigating individual cell groups, assessing cell health, testing under load conditions, and monitoring self-discharge.
Battery Pack Testing Machine (120V 100A) After wiring the semi-finished battery pack, we go for capacity testing using the individual Battery Capacity Testing Machine. Using an advanced computer software, each process will be programmed before connecting the machine with semi-finished battery pack.
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.
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.
Lithium-ion batteries (LiBs) are the dominant electrochemical storage technology used in electric vehicles due to their high energy and power densities, as well as their long cycle life (Li et al., 2023). However, LiBs gradually self-discharge over time, which depends on temperature and state of charge (SoC).
