Title:
BATTERY SAMPLING CHIP AND BATTERY MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/050082
Kind Code:
A1
Abstract:
Provided in the present application are a battery sampling chip and a battery management system. The battery sampling chip comprises: a selector module, which comprises a first data selector and a second data selector, wherein both the first data selector and the second data selector are used for collecting state data of a first group of battery cells; an analog-to-digital conversion module, which is connected to the first data selector and the second data selector; and a data control module, which is used for sending alarm information when no converted state data sent by the analog-to-digital conversion module is received within a preset time period. By means of the redundancy design of data selectors, whether a selector module fails or is abnormal can be effectively determined, such that a battery management system comprising the battery sampling chip is prevented from monitoring erroneous state data. Compared with the prior art, the battery sampling chip provided in the embodiments of the present application improves the reliability of the battery sampling chip itself and also enhances the safety of the battery management system.
