The invention relates to a cell data acquisition method and device, a battery management system, a storage medium and a program product. The method comprises the following steps: a main processor stores a data acquisition instruction of a battery cell in a shared storage area, and acquires battery cell data stored in the shared storage area by a coprocessor according to a communication state parameter stored in the shared storage area by the coprocessor; the shared storage area represents a storage area for data sharing between the main processor and the coprocessor; the data acquisition instruction is used for indicating the coprocessor to acquire cell data; the communication state parameter is used for representing an instruction transmission state between the coprocessor and a third-party unit acquiring the cell data; in the method, the main processor only needs to store the data acquisition instruction of the battery cell in the shared storage area to indicate the coprocessor to acquire the battery cell data without the main processor, and finally only needs to read the battery cell data stored in the shared storage area by the coprocessor, so that the load of the main processor is reduced, and the operation stability of the system is improved.
本申请涉及一种电芯数据获取方法、装置、电池管理系统、存储介质和程序产品。该方法包括:主处理器将电芯的数据获取指令存入共享存储区域,并根据协处理器存入共享存储区域中的通讯状态参数,获取协处理器存入共享存储区域的电芯数据;共享存储区域表示主处理器和协处理器之间数据共享的存储区域;数据获取指令用于指示协处理器获取电芯数据;通讯状态参数用于表征协处理器与获取电芯数据的第三方单元之间的指令传输状态;上述方法中,主处理器只需将电芯的数据获取指令存入共享存储区域,以指示协处理器获取电芯数据而无需主处理器获取,最终只需读取协处理器存入共享存储区域的电芯数据,降低了主处理器的负载,提高了系统运行的稳定性。
