Tesla 18650 Cell Specs

The 18650 cell that tesla uses has a 3 1ah capacity at 3 6v.

Tesla 18650 cell specs.

The tesla battery packs using panasonic 18650 batteries can charge no faster than this. They will also be found in the model 3 later this year but for now the 18650 cell is the only one used by tesla in its vehicles. The recommended max continuous discharge rate for nca is 1c for max cycle life but can go much higher if you don t mind losing some of its cycle life. It s worth noting that.

2170 and 18650 size. The tesla powerbank cannot currently be shipped to alaska hawaii or puerto rico due to freight restrictions. Tesla could certainly use more 2170 cell production capacity for model 3 and model y but the bigger issue is that if panasonic switches its existing 18650 lines to it model s and model x won t. However 18650 cell is very limited by its size volume which is generally between 2 0 2 6ah cell for mass production.

Tesla allows charging current to be up to 4 amperes. These used 18650 tesla battery modules from a 85kwh model s. These are currently the best battery on the market for energy density allowing many classic conversions to get well over 200 miles per charge. They supposedly have a longer lifespan than panasonic s off the.

The maximum charging voltage for a panasonic cell is 4 2 volts. Like all li ion chemistries. Single 18650 cell with 3350mah capacity. It s worth noting jason hughes s teardown of the 100kwh battery pack he notes that it is 102 4 kwh of actual capacity with 8 256 cells which suggests each cell is still only 258 to 276 wh kg for 12 4 watt hours divided by 0 045 0 048 kilograms as panasonic 18650s are typically around 45 48 grams.

At present while there is a huge demand for more energy density for lithium battery the current 18650 cell can t increase much on capacity. Panasonic specifies a maximum charging current of 2 amperes per cell. They are rated at 500 amps 750 amps peak.
