from chemistry to pack
Yanti Innovative Electromotive Solutions Pvt Ltd Abstract A module at 78% state-of-health (SoH) is scrapped as end-of-life; after reconditioning, it powers a stationary storage for three more years. Another at 82% SoH fails weeks into revival. Conventional metrics cannot explain the difference. Field analysis of >1,000 EV modules across platforms reveals that recoverability the probability … Read more
Is it necessary to clean battery terminals before welding? This is a common question for those focused on battery production processes. Author Jerry Wan Laser cleaning of terminals is a critical step in the assembly of battery modules. It effectively removes surface impurities and creates optimal conditions for laser welding, which in turn enhances product … Read more
The Renault 5 E-Tech has two battery packs defined by usable energy of 40kWh and 52kWh. Initially the vehicle is launched with the 52kWh usable pack. This pack is assembled by Ampere, a subsidiary of Renault and using AESC pouch cells. This post has been built based on the support of and sponsorship from: Quarto Technical Services, Eatron … Read more
However we look at a battery pack design we end up with lots of cells being connected together. In parallel to increase the capacity and in series to increase the voltage. We end up with a complex system to manufacture and hence look for repeating patterns. These repeating patterns are important whether the pack is … Read more
Knowing the power demand for a battery cell or pack is really useful, but how do you turn that into a current demand? The following image shows the solution we use in the Battery Calculations Workbook and in the Vehicle Model. At first it can look daunting, but it is quite simple, maybe too simple … Read more
What do you need to know when benchmarking modules? This is all part of our thought process so that we can start to pull together the data you need. Hence, a high level list: This post has been built based on the support and sponsorship from: Thermo Fisher Scientific, Eatron Technologies, About:Energy and Quarto Technical Services. What have we missed? … Read more
Cell component mechanical tests are extensive and required in order that a more detailed understanding of how the cells behave can be established. The battery cell is a complex: chemistry, electrical, thermal and mechanical system. Cycle ageing is seen as a deteriation in the chemistry of the cell, but should also be considered as a … Read more
Looking at the pouch cell design and edge cooling evolution allows us to appreciated the importance of battery cell electro-thermal behaviour. Fundamentally pouch cells are made from multiple layers of active material all applied to copper and aluminium electrodes that are sandwiched and compressed together. The copper and aluminium electrodes have very good in-plane thermal … Read more
