Hacker: Tesla has a new battery. Net power ~ 109 kWh, range over 400 miles / 640 km

Jason Hughes, a hacker who tweets as @ wk057, has discovered suggestions for Tesla's battery management firmware for batteries with a usable capacity of approximately 109 kWh. Such a large package has never been seen in Tesla or any other mass-produced passenger car.

Battery ~ 109 kWh and a cruising range of 640+ kilometers?

The data that Hughes came across was about BMS software, which is low-level software. Therefore, the hacker suspects that the information may be correct. And that they are not included in order to confuse competitors or other firmware researchers.

Package o net power 109 kWh that's roughly 113-114 kWh of total capacity as @ wk057 estimates. This amount of energy should allow the Tesla Model S to travel more than 640 kilometers on a single charge (source). Meanwhile, the latest version update Long range plus speaks of less than 630 kilometers from current battery with a capacity of about 100 kWh:

> New Tesla Model S / X "Long Range Plus" instead of "Long Range". The range increases to almost 630 and 565 kilometers.

In 109 kWh batteries, the lithium-ion cells will be grouped into 108 parts. The voltage across the case will be approximately 450 volts. It was immediately speculated that the extra capacity would be gained by dumping modules, as Elon Musk recently mentioned.

We, as editors of www.elektrowoz.pl, were interested in a slightly different question: why in the BMS software there is no mention of a larger battery capacity. The richest version of the Cybetruck promises a range of more than 800 kilometers, and a car of this size is a truck! - for ~ 109 kWh of energy, this distance is unlikely to be overcome.
