The cell to pack mass ratio is a simple metric to calculate and gives you an idea as to the efficiency of your pack design. The gradient of the line at 1.59 is 62.9% cell to pack mass ratio. I need a few more points here and we will gradually add more benchmarks.
The ratio depends on several factors, such as your daily energy consumption, location, energy needs of your solar setup (backup or off-grid), and budget constraints. For most applications, a good rule of thumb is to aim for a 1:1 ratio of batteries and watts or slightly more if you live in regions with limited sunlight, such as near the poles.
In a paper recently published in Applied Energy, researchers from MIT and Princeton University examine battery storage to determine the key drivers that impact its …
The ratio between energy output and energy input of a battery is the energy efficiency. (Energy efficiency reflects the ratio between reversible energy, which …
