Abstract: The present application provides an energy storage system, control method thereof, device, electronic equipment, and storage medium. The energy storage system comprises multiple interconnected battery devices and a communication network, where a battery device comprises a positive electrode and a negative electrode, and a battery device comprises a storage battery, a controller, and first and second switch modules; a positive pole of the storage battery is connected to a first terminal of the first switch module, the positive electrode and a first terminal of the second switch module are connected to a second terminal of the first switch module, and a second terminal of the second switch module is connected to a negative pole of the storage battery. The multiple battery devices can simultaneously perform disconnection and connection operations.

Abstract: The present application provides an energy storage system, which comprises: M energy storage batteries interconnected and a communication link, where an energy storage battery is provided with a unique controller configured to control a corresponding energy storage battery to connect to or bypass from the energy storage system, where the controller is configured to perform a balancing control method, where the controller is configured to: obtain a first state value of the corresponding energy storage battery, send the first state value to another M?1 controllers based on the communication link, receive second state values sent by another M?1 controllers, and determine whether to connect the corresponding energy storage battery to the energy storage system or bypass it from the energy storage system based on the first state value and the M?1 second state values. Technical solutions in the present application improves availability of an energy storage system.

Abstract: An embedded device detection method, comprising the following steps: executing a task by an embedded device, wherein the task comprises multiple functions; when an abnormal interruption occurs to the task, obtaining a stack pointer and a program counter corresponding to the abnormal interruption by a detection device, wherein the program counter is configured to record a memory address in use when the abnormal interruption occurs to the task; obtaining a stack space corresponding to a first target function being executed according to the program counter when the abnormal interruption occurs to the task; finding out a second target function before the first target function is executed according to the stack pointer and the stack space; and correcting the task according to the second target function.
