During a delivery event held at the Texas factory in the United States earlier this month, Tesla announced that the pure electric pickup truck Cybertruck will use an 800V high-voltage battery system, and the auxiliary battery system has also been upgraded from the original 12V to 48V.
Tesla has now shared relevant design documents for its 48V electrical architecture with third-party automakers. Subsequently, Ford CEO Jim Farley also expressed his gratitude to Elon Musk and spoke highly of this behavior as beneficial to the entire automobile industry. Elon Musk then responded: “You’re welcome.”
Note: The battery (commonly known as the battery) currently used in mainstream cars is a 12v battery pack composed of 6 lead-acid batteries connected in series. It mainly supplies power for lighting, in-vehicle entertainment, electronic control units and other low-power electronic equipment.
However, with the diversification of in-car entertainment and the integration of more and more electrical components into cars, existing 12V batteries can no longer meet the needs of cars.
The Cybertruck launched by Tesla has upgraded the auxiliary battery system to 48V, and the opening of this related design will inevitably have a major impact on the entire car. It will inevitably push car companies to adjust the internal wiring and structure of the vehicle, bringing changes to the entire ecosystem. change.
By upgrading the voltage from 12V to 48V, theoretically the current flowing through will be smaller, which can reduce losses during transmission and reduce temperature. It can also reduce the need for wire diameter, allowing the use of thinner wires to save weight and cost. .
