Estimate the Total Equivalent Lithium Load of a Battery
We frequently see the chemical factor lithium printed on power packs and commence to speculate how much of it was loaded into the battery. Let us go directly to the method how to compute the lithium content. Initially we must establish this data: first is the whole comparative lithium content (ELC) for one cell of the battery, second is the sum of cells in the battery. To figure out the ELC (in grams), ELC is equivalent to the battery’s power (in ampere-hours) multiply by zero. 3 then multiplied by the battery’s sum of cells. 18500 battery
Take those circumstance of an HP Compaq 367759-001 battery with 12. 8V, 8800 mAh, Liion technical specification as an example.
I want to get started by computing the ELC using the formula declared prior. We know the ability ranking to be 8800 mAh (milliamps) and we should convert it to My oh my (amp hours) to apply our formula and we have 8. 8 My oh my (8800 mAh equals eight. 8 Ah). And so we are now prepared to compute the HP Compaq 367759-001 battery one cellular ELC which is almost 8. 8 x 0. 3 equals 2. 64 grms.
Additionally, we are required to establish the total of cells from our chosen battery. The battery’s voltage was given at 10. 8V, we should divide that by the low voltage of one cell then we have the sum of skin cells in series as a result. Next is to divide the battery’s given ability (8800 mAh) by the nominal capability of one cell and get the resultant sum of cells in parallel. Nowadays we can compute the sum of cell in the battery by growing the series and similar results. Of all the cells in HP 367759-001, the number 18650 is frequently used. It has a standard low volt quality of 3. 6V and 2200 mAh nominal capacity. We are now willing to compute the sum of cells in the HEWLETT PACKARD Compaq 367759-001 battery with this: (8800 mAh/2200 mAh) x (10. 8 volts/3. 6 volts) equals doze cells.
To conclude our try to find the total ELC in HEWLETT PACKARD Compaq 367759-001 battery, we need to do the subsequent computation. We have the data for one cell’s ELC at 2. 64 grams and the sum of cells in the battery is doze cells. Lastly, compute the total equivalent lithium fill of the battery by performing this calculation: 2. 64g x 12 sama dengan 31. 68 grams.
