In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits a detailed description of some known functions and known components.

the key detection processing module 1000 and the main processing module 1001 are used for outputting an enabling signal to control the enabling power supply module 1002 to work or stop working; the enable power module 1002 is operative to power the master processing module 1001.
As shown in fig. 1, the key detection processing module 1000 and the main processing module 1001 are independently powered, and the key detection processing module 1000 maintains continuous power supply. In one embodiment, the key detection processing module 1000 is powered by the low power consumption LDO (low dropout regulator) separately to detect the key to be detected. The key detection processing module 1000 may enter a sleep state according to control. The sleep state is awakened, and the awakening mode comprises timer awakening, watchdog timeout reset, key awakening and the like.
In one embodiment, the key detection processing module 1000 includes a key detection MCU;
the master processing module 1001 includes a master MCU.
The enabling signal can be output by the key detection processing module 1000 and the main processing module 1001, so as to control the enabling power supply module 1002, and the enabling power supply module 1002 supplies power to the main processing module 1001 when supplying power, so that the main processing module 1001 is electrified; after the power supply module 1002 is enabled to stop supplying power, the main processing module 1001 is powered down to stop working.
The enabling signal may be transmitted by the key detection processing module 1000 and the main processing module 1001. In one embodiment, the enable signal includes a first level and a second level. Wherein, the first level is used to control the operation of the enabled power module 1002, and the second level is used to control the disabled operation of the enabled power module 1002. For example, the first level may be a logic high level and the second level may be a logic low level. On this basis, if the key detection processing module and the main processing module 1001 select one to output the first level, the power supply enabling module 1002 can be driven to work; the key detection processing module 1000 and the main processing module 1001 need to output the second level at the same time, so that the power supply enabling module 1002 can be driven to stop working.

For example, in the energy storage battery system, each key to be tested collects electrical information according to design characteristics, and key adhesion mark information and key states are determined. According to the design of the existing energy storage battery system, key adhesion mark information is used for marking the occurrence of abnormality of a key to be detected, and key adhesion mark bits are used as expression in the system design. The key state represents the working state of the key to be tested, including whether the key to be tested is pressed, the duration of pressing, the duration of short circuit, the duration of lifting and the like.

In one embodiment, the first time threshold is adjusted according to the design of the energy storage battery system, and may be 10-20 seconds. As a preferred embodiment, the first time threshold is 15 seconds. And when the duration of the pressed time of the key to be tested is greater than the first time threshold, judging that the key adhesion possibly exists, and lifting the key to be tested through an enabling signal.
If the key to be detected is not lifted, the key state is judged to be short circuit, and if the short circuit time of the key to be detected is longer than a second time threshold, a key adhesion flag bit is set for the energy storage battery system to indicate abnormal key adhesion.
The second time threshold may be preset according to the key attribute of the key to be tested, and may be 1min-10min, preferably 5min.
In one embodiment, as shown in fig. 3, the process of adjusting the enable signal according to the key adhesion flag information and the key state in step S101 further includes step S203:
s203, when the key to be tested is not pressed, entering a dormant state.

s204, outputting a second level enabling signal when the duration of the pressed key to be tested is smaller than the first time threshold value;
s205, or when the key to be tested is lifted, outputting a second level enabling signal;
s206, or outputting a second level enabling signal when the short circuit time of the key to be tested is smaller than a second time threshold value.
It should be noted that, the key detection processing module 1000 outputs the enable signal of the first level or the second level, and the enable power supply module 1002 needs to be controlled in combination with the enable signal of the main processing module 1001.
