Document Type and Number:
WIPO Patent Application WO/2023/035118
Kind Code:
A1
Abstract:
Embodiments of the present application provide an over-discharge protection method and system, a vehicle, a battery management system, and a storage medium. The vehicle comprises a power battery, a switch unit, a starting unit, and a battery management system. The method is applied to the battery management system. The method comprises: detecting a current amount of charge of a power battery; when the current amount of charge is less than a first preset amount of charge and greater than or equal to a second preset amount of charge, and when the switch unit is in a connecting state, disconnecting the switch unit; when the current amount of charge is less than the first preset amount of charge and greater than or equal to the second preset amount of charge, and when the switch unit is in a disconnected state, if a hardware triggering signal is received, connecting the switch unit. The second preset amount of charge is less than the first preset amount of charge. In the present application, when the current amount of charge of a power battery is still sufficient to start the vehicle, a discharge circuit of the battery is disconnected to reduce the energy consumption of the power battery, such that the energy of the power battery is used to start the vehicle as much as possible, thereby improving the user experience.
