Quality inspection specifications for lithium battery energy storage power stations

What is Quality Management in lithium ion battery production?

Quality management for complex process chains Due to the complexity of the production chain for lithium- ion battery production, classical tools of quality management in production, such as statistical process control (SPC), process capability indices and design of experiments (DoE) soon reach their limits of applicability .

What is the production chain of lithium ion batteries?

Production chain for lithium-ion batteries Lithium-ion cells are galvanic elements that convert electrical energy into chemical energy and vice versa . Hence, they are able to store and release large amounts of energy, e.g. electricity generated by solar or wind energy used to power an electric vehicle.

What is quality-oriented production planning in Assembly of battery modules?

A tool for quality-oriented production planning in assembly of battery modules was developed by , defining critical product and process characteristics and deriving appropriate quality assurance systems using a measurement equipment catalogue.

Are quality management tools limiting the production chain of lithium-ion cells?

It has been shown that current quality management tools easily face their limits when applied to the production chain of lithium-ion cells due to its complexity and the need for real time processing of collected data.

What is the product model for lithium-ion cells?

A detailed product model for lithium-ion cells was presented by . Most common formats cover cylindrical cells, prismatic hard case cells and pouch cells. The production of lithium-ion cells has a big impact on cost and quality of the batteries [3,17].

Can lithium-ion batteries be used in electric vehicles?

Due to their large energy and power density, lithium-ion batteries are among the most promising solutions for the application in electric vehicles (EV) . Although lithium-ion batteries have become well established in consumer electronics, there are several challenges yet to be overcome for batteries in electric vehicles.
