from chemistry to pack
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
Ola S1 E-Scooter are the number one selling scooters in India in the electric 2 wheeler market. In 2023 Ola sold 252,647 units (till dec21). Ola S1 comes in three models: Ola S1 Pro, S1 Air and S1X. In this article we will see benchmarking of OLA battery pack for S1. S1 air and X … Read more
When we say cell energy density we need to consider if this is gravimetric (Wh/kg) or volumetric (Wh/litre). The energy content of the cell will be determined by the discharge rate, temperature and other parameters. Discharge rate capability of a new SAFT MP 176065 xtd battery. As you can see, at a C/8 discharge rate … Read more
Pack Gravimetric Energy Density has the units Wh/kg and is a key pack metric. The optimum metric is a high Wh/kg. Hence: The best you can achieve will be less than or equal to the cell Wh/kg that the pack is made from. Perhaps the simplest of the battery metrics as the capacity of the cell … Read more
