[0003] The low-voltage battery is an important component of pure electric vehicles, responsible for supplying power to various on-board electrical systems. Since the motor drive system of pure electric vehicles replaces the traditional internal combustion engine system, the structural parts in the front cabin are more complex, and there are more high and low voltage wiring harnesses, leaving less space for the layout of the low-voltage battery bracket, and at the same time, higher requirements are placed on its structural rigidity.
