10. The automatic generation method based on the functional configuration of the lithium-ion power battery according to claim 8, characterized in that: the condition determination in S5 specifically includes determining whether a charging overcurrent switch defined by a # define macro in project _ define.h is configured to be 1, and if so, executing a corresponding protection logic API; if the configuration is not 1, no code related to charging overcurrent is generated;
the API calls protection thresholds and protection delays in proje _ define.c and proje _ define.h to perform corresponding logic protection processing, in product application, if the current voltage temperature of the working environment does not reach the condition that the battery is prohibited from using, the API maintains the normal operation of the system, and if the current/voltage/temperature of the working environment reaches the condition that the battery is prohibited from using, the API prohibits the normal operation of the system and enters the protection state.
