Tesla optimizes charging performance, Cybertruck is about to achieve a 20% speed increase

News on April 10, Tesla recently announced that it will increase the charging speed of its electric pickup truck Cybertruck through OTA (Over-The-Air) updates, and the increase is expected to reach 20%. This move demonstrates Tesla’s continued innovation capabilities in electric vehicle technology and software updates.

When Tesla delivers new cars, it usually adopts a strategy of hardware first and software later. Taking Cybertruck as an example, the vehicles currently delivered are not yet equipped with all Autopilot and FSD (fully autonomous driving) functions, although these intelligent driving functions are included in the car purchase package. Tesla revealed that these features will be gradually provided to car owners in subsequent OTA updates. This strategy allows Tesla to provide more smart driving features to owners upon delivery.

#The data editor learned that for the power system of electric vehicles, the role of software updates is often ignored, but in fact there is still room for optimization. Tesla often imposes software restrictions on the power system in the early stages of launching new cars to ensure the stability and reliability of the hardware. With an in-depth understanding and verification of hardware performance, Tesla will gradually unlock more performance through software updates. The increase in Cybertruck charging speed is based on this strategy.

Early test results show that Cybertruck’s charging curve performance is not ideal. During the charging process, the peak charging power will drop rapidly after reaching 255kW. When the charging capacity reaches only 20%, the charging power begins to decrease significantly, until the power drops to 150kW when the charging capacity is 40%. When the charging capacity is 60%, the power drops to 100kW, and then the charging speed is maintained at 75-80kW until the charging capacity reaches 90%. These test results are cause for concern because of the high expectations placed on the Cybertruck. Its claimed large-capacity battery and high-efficiency charging system allow users to charge quickly for longer use. However, test results showed that the Cybertruck’s charging speed did not meet expectations. During the charging process, maintaining a lower charging power may cause users to wait longer for charging to complete. This may be problematic for some users. In response to this issue, Drew Baglino, Tesla’s head of energy and powertrain engineering, said that the team will optimize the charging curve to enable the Cybertruck to add up to 154 miles in 15 minutes. (approximately 247.84 kilometers) cruising range. This update will increase range by 20% in the same charging time compared to the current estimate of 128 miles (approximately 206 kilometers).

Baglino revealed that this important OTA update is expected to be pushed to Cybertruck owners later this quarter, that is, before the end of June. This update will not only increase charging speed, but also further optimize the vehicle's endurance performance and user experience, demonstrating Tesla's leading position in the field of electric vehicle technology.
