Title:
BATTERY POWER CONTROL METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/020842
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a battery power control method and apparatus, and a device and a storage medium. The method comprises: acquiring, in real time, electrical parameters of a battery; and performing closed-loop control on the allowable power of the battery according to the electrical parameters. In the present application, an allowable power is adaptively controlled according to electrical parameters, and the allowable power of a battery cell is provided on the basis of the actual capacity of the battery cell, such that the energy of the battery is more fully exerted, the problem of undervoltage under any operating condition and any battery cell state is prevented from occurring, and the available power of the battery can be exerted to the maximum extent with no undervoltage. With regard to low-temperature and low-SOC emergency acceleration or emergency deceleration, abnormal aging of a battery cell, etc., an under-voltage caused by a sharp voltage drop resulting from a large-current operating condition can be effectively avoided, and it is ensured that the energy of a battery can be fully exerted, such that the acceleration capability of an electric device in a low-temperature and low-SOC state is better.
