Estimate the Overall Equal Lithium Load of a Battery
We typically see the chemical factor lithium printed on batteries and we start to question how a lot of it was loaded into the battery. Allow us go right to the method on how to compute its lithium content. To begin with we need to set up the subsequent information: very first is the total equivalent lithium articles (ELC) for 1 cell of the battery, second is the sum of cells in the battery. To compute the ELC (in grams), ELC is equivalent to the battery’s electrical power (in ampere-hrs) multiply by .three then multiplied by the battery’s sum of cells.
Consider the situation of an HP Compaq 367759-001 battery with ten.8V, 8800 mAh, Li-ion specialized specification as an example.
Enable us get started by computing the ELC utilizing the formula declared previously. We know the power ranking to be 8800 mAh (milliamps) and we must convert it to Ah (amp hours) to use our system and we have eight.8 Ah (8800 mAh equals 8.8 Ah). And so we are now all set to compute the HP Compaq 367759-001 battery a single cell ELC which is eight.eight x .3 equals two.64 grams.
In addition, we are needed to set up the sum of cells from our chosen battery. The battery’s voltage was offered at 10.8V, we should divide that by the minimal voltage of a single cell then we get the sum of cells in collection as a result. Next is to divide the battery’s provided potential (8800 mAh) by the nominal functionality of one particular mobile and we get the resultant sum of cells in parallel. Now we can compute the sum of cell in the battery by multiplying the collection and parallel final results. Of all the cells in HP 367759-001, the number 18650 is often used. It has a common lower voltage of 3.6V and 2200 mAh nominal potential. We are now all set to compute the sum of cells in the HP Compaq 367759-001 battery with this: (8800 mAh/2200 mAh) x (ten.eight volts/three.6 volts) equals 12 cells.
To conclude our endeavor to find the total ELC in HP Compaq 367759-001 battery, we need to do the subsequent computation. We have the data for one cell’s ELC at two.64 grams and the sum of cells in the battery is twelve cells. Lastly, compute the whole equal lithium load of the battery by carrying out this calculation: 2.64g x 12 = 31.68 grams.
