The LG E66a pouch cell is used in the Audi e-tron GT quattro and the 2019 Porsche Taycan that shares the same platform. Key features Designed to meet Dimensions Note that this cell has a single piece outer wrap and the tabs have been moved towards the bottom of the cell. These two features significantly … 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
Looking at the benchmarks there are a number of pouch cell cooling options that have been used and threads where we can see improvements to designs. Firstly thought it is worth just reminding ourselves of the heat generation mechanism in a battery cell. Heat Generation in a Cell can be defined quite simple for the … Read more
The 2019 Porsche Taycan comes with a total/gross 79.2kWh or 93.4kWh battery pack Turbo S Performance Battery Plus This is the largest battery capacity on offer in 2019 and the highest power. Specifications: The 270kW continuous discharge power is based on the charge power and hence the overall system thermal and electrical limits for extended … Read more
