Tesla 18650 Battery Cell Specs

The most popular battery pack supplied by tesla contains 7 104 18650 cells in 16 444 cell modules capable of storing up to 85 kwh of energy.

Tesla 18650 battery cell specs.

Understanding different li ion specifications. Tesla 18650 p100d cell. Tesla s old versus new battery format. As outlined in hughes s blog post tesla was able to fit more of its cylindrical 18650 lithium ion battery cells into each of the 16 modules making up the p100d battery.

More 18650 battery cells. Tesla is hoping to produce the cells at about the same cost. We think jack rickard used an older 18650 cell in his calcs ref 51 31 he stated that the 2170 s energy density was better than the 18650 s. We see a 15 increase in volume density and a 15 increase in weight density.

If they reach a capacity of 6 000 mah per cell the improvement rises to 20. That s right since 2013 the battery packs of a tesla contains 7 104 individual 18650 cells which stores up to 85kwh of energy or enough juice to power a full size car. The good thing about 18650 batteries was that these were commodity lithium ion battery cells and allowed tesla to purchase reliable cells from its battery supplier panasonic at the scale it. The most important product tesla has developed so far that will be used from powering homes to space travel.

Model s modules are comprised of 3400mah cells arranged in a 74p6s configuration. Tesla 2170 battery cells are about 50 percent more energy dense than the previous 18650 cells. Nowadays you can find 18650 batteries in a plethora of products from chainsaws and scooters to even a tesla model x. The 18650 cell is a li ion type battery which has found its application in many fields such as portable electronics like torch lights electric vehicles cars like tesla and much more.

Note that these numbers are on cell level only in a battery pack you also need interconnections control hardware and cooling. They are rated at 500 amps 750 amps peak. In 2015 panasonic altered the anode design increasing cell capacity by about 6 enabling the battery packs to store up to 90 kwh of energy. The main reason for this battery being successful is its properties compared to its competitors.
