Drawing from this patent and aligning it with Tesla's publicly available information, we present an elucidation of the battery pack system within its humanoid robot.

▲Patent Drawing 1

From Patent Drawing 1, it is evident that Tesla's humanoid robot employs a battery pack system comprising cylindrical battery cells grouped together and housed within a protective enclosure. According to Tesla's public disclosures, this battery pack system boasts an energy capacity of 2.3KWh at a voltage of 52V. However, the 52V voltage specification raises some skepticism, leading us to question the accuracy of the information released by Tesla.

▲Patent Drawing 2

Patent Drawing 2 reveals the internal layout of the battery cells within the pack enclosure. Notably, a distinct dividing line runs through the center of the battery pack system, indicating it comprises two modules.

Each module appears to house 63 cells, as depicted in the drawing. Considering Tesla's battery cell technology roadmap, it is plausible that the humanoid robot utilizes mature 21700 battery cells known for their higher capacity. Referring to the publicly available 2018 Tesla Model 3 Cell Report, Panasonic's 21700 battery cell has a capacity of 4.78Ah. The calculation is as follows: 63 x 2 x 3.7 x 4.78 = 2.22KWh. This figure aligns closely with the 2.3KWh disclosed by Tesla, and only the specifications of 21700 battery cells fit this calculation. Consequently, regardless of the calculation method, the officially stated 52V for the humanoid robot's battery pack remains elusive.

Furthermore, it can be inferred that the two modules are connected in series, facilitating subsequent maintenance and servicing in the aftermarket.

▲Tesla Humanoid Robot Cooling Method

In practical applications, the humanoid robot expends energy with every movement, a process that occurs frequently and continuously in industrial settings. Therefore, thermal management remains a paramount concern for humanoid robots.

This patent showcases Tesla's ingenious integration of the cooling systems for both the humanoid robot's computer and battery pack. Both systems feature heat dissipation fins, with a shared air duct running between them. A fan actively draws air to simultaneously cool both the computer and battery pack systems. The above interpretation is based on the information disclosed in Tesla's patents related to its humanoid robot.

As humanoid robots continue to mature and gain market traction, heightened demands will be placed on the battery pack system's energy capacity and thermal management.

Beyond electric vehicles, the humanoid robot presents Tesla with another significant application scenario and a vast, untapped market, leveraging its expertise in electronics, software, chips, and battery technology. This platform will continue to monitor these developments and stay abreast of related information on local humanoid robot battery pack systems.
