[0024] Please refer to Figures 1 to 6 A detector for an energy storage fire protection system includes a first sensor 2, a first circuit board 3, a second sensor 4 and a second circuit board 5. The first circuit board 3 is provided with the first sensor 2, and the second circuit board 5 is provided with the second sensor 4; the first circuit board 3 and the second circuit board 5 are stacked and electrically connected.

Compared with the multi-sensor arrangement on the same circuit board, the space between the multi-layer circuit boards can form good heat dissipation and ventilation, reduce the temperature impact between multiple sensors during operation and increase air circulation, thereby improving the detection accuracy and sensitivity of the sensor.

[0026] Furthermore, the second sensor 4 is disposed on a side of the second circuit board 5 opposite to the first circuit board 3 , and a connector 7 is disposed on a side of the second circuit board 5 away from the first circuit board 3 .

[0027] From the above description, it can be seen that the second sensor 4 and the connector 7 are respectively arranged on the two sides of the second circuit board 5 to reasonably utilize the space of the circuit board; the connector 7 is used to connect with the controller to transmit sensing data and ensure power supply.

[0028] Furthermore, a plug-in terminal 8 perpendicular to the second circuit board 5 is provided on the second circuit board 5 , and the plug-in terminal 8 is plugged into the first circuit board 3 .

[0029] As can be seen from the above description, the plug-in terminal 8 on the second circuit board 5 is plugged into the first circuit board 3 to electrically connect the two, without the need to provide independent connection structures for each to be connected in parallel with other external components.

[0030] Furthermore, four plug-in terminals 8 are provided, and the four plug-in terminals 8 are arranged at intervals around the center of the second circuit board 5 .

[0031] It can be seen from the above description that the plug-in terminals 8 are used for electrical connection between two circuit boards on the one hand, and for mounting support of the first circuit board 3 on the other hand, and the arrangement of the four plug-in terminals 8 can ensure sufficient supporting strength.

[0032] Furthermore, the first sensor 2 is arranged on a side of the first circuit board 3 away from the second circuit board 5 .

[0033] It can be seen from the above description that the first sensor 2 and the second sensor 4 are arranged in a non-opposite manner, so there is no need to design a yielding structure, while ensuring that the heat generated by the two sensors during operation will not affect the other sensor.

[0034] Furthermore, the first sensor 2 is a VOC sensor, and the second sensor 4 is a H2 sensor or a CO sensor.

[0035] From the above description, it can be seen that a VOC sensor is used to detect smoke and volatile organic compounds when the battery inside the relevant energy storage system is in thermal runaway, and a H2 sensor or a CO sensor is used to detect H2 and CO gases when the battery inside the relevant energy storage system is in thermal runaway.

[0036] Furthermore, a labyrinth structure 9 is provided on the first circuit board 3 , and the sensing end of the VOC sensor is arranged in the labyrinth structure 9 .

[0038] Furthermore, a third sensor 6 is included, and the third sensor 6 is disposed on the second circuit board 5 .

[0039] From the above description, it can be seen that multiple sensors are used to comprehensively and accurately sense the parameters of the external environment changes inside the energy storage system, so that fire risks can be sensed and alarms can be issued in a timely manner in the early stages.

[0040] Furthermore, the second sensor 4 and the third sensor 6 are disposed on the same side of the second circuit board 5 , and there is a gap between the second sensor 4 and the third sensor 6 .

[0041] As can be seen from the above description, the design of the second sensor 4 and the third sensor 6 on the same side of the circuit board improves the compactness of the arrangement of the internal components of the device, and ensures that the two do not affect each other through a certain spacing design.

[0042] Furthermore, it also includes a shell 1 and a panel 10, a plurality of indicator lights 101 are provided on the side of the second circuit board 5 away from the first circuit board 3, the first sensor 2, the first circuit board 3, the second sensor 4 and the second circuit board 5 are all arranged in the shell 1; an opening is provided on the side of the shell 1 opposite to the second circuit board 5, and the indicator lights 101 cooperate with the opening; the panel 10 is locked to the side of the shell 1 where the opening is provided, and an opening and a text mark are provided on the panel 10 corresponding to the indicator lights 101.
