[0002] An energy storage system (ESS) is a device or system that can store electrical energy and release it when needed. They are often used to balance supply and demand in power systems, optimize energy utilization, and improve grid stability and reliability.

[0003] If the battery system within the energy storage compartment is overcharged or over-discharged for a prolonged period, the chemical reactions within the battery may become uncontrolled, leading to excessive heat generation and ultimately a fire risk. As battery components age, their internal chemical reactions and heat management capabilities may decline, increasing the risk of thermal runaway. Using particle detectors to provide early warning of battery thermal runaway within the energy storage compartment is an advanced technology that requires real-time sampling and monitoring of the air within the compartment.

This results in inaccurate real-time monitoring and an inability to timely predict the direction of safety risks. At the same time, when sampling and monitoring the air in the energy storage cabin, how to timely control heat dissipation and ensure the stability of the monitoring work is also a key research task.

The fresh air squeezes the old air in the detection cavity out of the detection cavity through the vent of the air intake module, and then is discharged out of the cabin through the exhaust pipe of the sampling box, thereby realizing the ventilation operation. When it is necessary to sample the air in the energy storage cabin again, the air intake module is turned on again to draw air into the energy storage cabin for real-time detection. This method enables the air in the detection cavity to be unaffected by the previous detection, thereby further improving the accuracy of real-time monitoring and improving the monitoring efficiency.

The air intake module 200 and the ventilation module 300 have the same structure. The two opposite walls of the sampling box 100 are respectively penetrated by a first mounting hole 120 and a second mounting hole 130, and a third mounting hole 160 is opened on the adjacent wall connected between the two side walls.

[0036] The sampling box 100 is provided with a detection base 700, the detection base 700 has a detection cavity 740, and the detection cavity 740 is provided with a particle sensor 900;
