A recently granted patent (Publication Number: US11827112B2) discloses a battery assembly designed for electric vehicles. The assembly includes multiple high-voltage battery packs, a front power distribution box, and a rear power distribution box. These components are interconnected in parallel, with each battery pack operating within a voltage range of 520 to 800 volts. Additionally, each battery pack is configured to operate within 12 volts of each other, ensuring uniform performance across the assembly. The design also features sub-assemblies with specific positive and negative connectors for efficient power distribution.

Moreover, the patent outlines methods for maintaining voltage within the high-voltage battery assembly. One method involves selecting a current battery pack based on voltage measurements, activating it if the difference from the previous measurement is within a predetermined threshold. Another method focuses on activating specific battery packs based on voltage differences, ensuring optimal performance and balance within the assembly. These innovative approaches aim to enhance the efficiency and longevity of high-voltage battery systems in electric vehicles, contributing to the overall advancement of sustainable transportation technologies.
