The cell to pack volume ratio is the total volume of the cells divided by the volume of the battery pack.
- 70.2% BYD Seal 82.56kWh
- 50.6% Zeekr 001 140kWh
- 46.7% VW ID4 62kWh
A significant issue with these numbers is the accuracy of the battery pack volume as it is based on overall dimensions and very few packs are rectangular. The following graph shows the spread of pack volume data when we look across all applications.
