from chemistry to pack
We have initial data for the 2026 BYD Short Blade 2.0 cell based on a shared [1] teardown of a 75.6kWh pack. Specifications Charge Rate – supports a massive 8C peak charge rate. Under optimal conditions with the right charger, this rate allows the short blade battery to charge from 0% to 80% (and potentially … Read more
Look at the data and what we can infer about the Geely Aegis Short Blade battery cell. A blade cell that has an energy density of 192Wh/kg. We know that this cell is destined for the Geely Galaxy E5 and has two pack sizes: 49.52kWh and 60.22kWh. Using these two numbers we can estimate the … Read more
What makes a Blade or Prismatic cell what it is? Blade cells are long, thin and have a terminal at each end. But so do some prismatic cells. Is it the ratio of the side dimensions? The following graph shows data from the Cell Database where we have plotted the ratio between the middle dimension … Read more
Not many details around the BYD Shark PHEV, but worth sharing what we know. The image shows a rectangular battery pack, typical of the BYD Blade design. This uniform shape keeps the cost low, but will challenge the packaging of the driveline and in particular propshafts.
