from chemistry to pack
With so much data now available in the Battery Pack Database it is interesting to look at Cell to Pack Mass Ratio by Chemistry and Format. Note that for this analysis we have excluded all of the BESS packs as they tend to not be as mass sensitive as mobile applications. The fixed lines showing … Read more
2026 Renault Megane E-Tech LFP battery pack with LG Energy Solutions pouch cells and a Cell to Pack design. However, we immediately feel that this isn’t the best battery package when we see Renault’s own description: Thanks to the larger battery, the new Megane E-Tech Electric is slightly taller (20 mm) than before and also … Read more
We have already looked at the BMW iX3 Neue Klasse Battery and the BMW Gen6 EV Battery Technology behind it. The second Neue Klasse model, the BMW i3 (badged NA0, reviving the i3 name for an all-electric 3 Series), uses the same Gen6 battery system, so this is really a companion piece rather than a … Read more
When we look at the battery pack design for a vehicle we want to minimise the overall weight and hence need the cells to work structurally as part of the pack design. This leads us to Thermally Conductive Adhesives (TCAs) as a means of fixing cells to cooling systems and bonding them into a battery … Read more
The 2026 VW Polo MEB+ has been talked about for some time as this will be the first vehicle to take the PowerCo unified cell. The technology partner for these cells is Gotion and we have already seen numbers for the cells. This post has been built based on the support of and sponsorship from: Quarto Technical … Read more
We have seen cell to pack battery designs from BYD and CATL. BYD with their ground breaking Blade design has brought LFP chemistry back into the world of EV’s. Cell to Pack Cell to Pack is all about reducing cost and increasing the volumetric density of battery packs. This is primarily aimed at road vehicle … Read more
The CATL Qilin CTP 3.0 is their second generation cell to pack design. Qilin is named after a legendary creature from China. The latest CATL post suggests that this integrated system can increase the energy density to 255Wh/kg for ternary battery systems (NMC, NMCX etc), and 160Wh/kg for LFP battery systems. Essentially removing the overheads … Read more
