The first circuit breaker 41 is connected to the power supply. The circuit protection device 42 is connected to the first circuit breaker 41. The voltage converter 43 is connected to the circuit protection device 42, the control panel 10, and the alarm main control platform 20, respectively.

[0048] In this embodiment, a first circuit breaker 41 with leakage protection function and a circuit protection device 42 are provided in the power supply system of the fire protection charging device 1. The first circuit breaker 41 is connected to an external 220V AC power supply. By controlling the switch of the first circuit breaker 41, the overall circuit of the charging device can be protected to reduce the damage caused by abnormal conditions such as circuit overload and short circuit. The circuit protection device 42 can further strengthen the protection of the charging device against lightning surge faults. Finally, through the voltage converter 43, the 220V AC power is converted into a voltage that can be used by the control panel 10 and the alarm main control platform 20, such as 24V DC power, to power the control panel 10 and the alarm main control platform 20. In addition, in combination with Figure 2 As shown, the circuit protection device 42 is also connected to the control board 10 , and the control board 10 can monitor the working status of the circuit protection device 42 .

[0049] Optionally, the circuit protection device 42 includes: a surge protector and a leakage protector.

[0050] Optionally, the voltage converter 43 includes a 220V AC to 24V DC voltage converter.

[0051] The surge protector can detect the peak current generated by lightning strikes, electrostatic induction, etc. in the circuit, and conduct and shunt it to the ground in a very short time, thereby reducing damage to the charging equipment, improving the reliability and stability of the charging equipment, and ensuring the normal operation of the charging equipment. The leakage protector can detect the leakage current in the circuit and quickly cut off the circuit to prevent users from electric shock and charging equipment from leakage.

[0052] Optionally, the surge protector includes an inductive surge protector or a capacitive surge protector.

[0053] Optionally, the leakage protector includes a distribution type leakage protector or a protection type leakage protector.

[0054] Combination Figure 3 As shown, optionally, the control system further includes: a battery charge and discharge management unit 51 and a backup battery 52. ​​The battery charge and discharge management unit 51 provides a backup power supply to the control system when the input mains power is cut off, and is respectively connected to the circuit protection device 42, the control board 10 and the alarm main control platform 20. The backup battery 52 is connected to the battery charge and discharge management unit 51.

[0055] A backup battery 52 is provided in the control system. When the first circuit breaker 41 or the circuit protection device 42 controls to disconnect the input mains power, the backup battery 52 can be discharged through the battery charge and discharge management unit 51 to supply power to the control panel 10 and the alarm main control platform 20, so that the control system can realize comprehensive fault reporting and real-time monitoring. Under normal circumstances where the input mains power is normally supplied, the battery charge and discharge management unit 51 can charge the backup battery 52. ​​In addition, combined with Figure 2 As shown, the control board 10 can also communicate with the battery charge and discharge management unit 51 via RS485 communication to obtain the mains power supply status and battery charge and discharge status in real time.

[0056] Combination Figure 4 As shown, the embodiment of the present disclosure provides a fire protection charging device 1, including: a fire protection charging device body, and a control system of the fire protection charging device as described above. The fire protection charging device body includes one or more charging compartments 70, which are arranged in the fire protection charging device body. The control system is arranged in the fire protection charging device body.

[0057] Combination Figure 4 As shown, the fire protection charging device 1 provided by the embodiment of the present disclosure is described by setting four charging compartments 70. In different embodiments, different numbers of charging compartments 70 can be set according to charging requirements. During the charging process of each charging compartment 70, the control system of the fire protection charging device can monitor the charging compartment 70 in real time, and when it is determined that there is a fire hazard, an alarm signal is issued, and corresponding prevention or fire extinguishing measures are executed to realize the fire protection function of the charging device.

[0058] Combination Figure 2 and Figure 4 As shown, optionally, the fire protection charging device 1 further includes a water level sensor 61. The water level sensor 61 is disposed at the bottom of the fire protection charging device body and is connected to the control panel 10.

[0059] The water level sensor 61 is used to monitor the water ingress of the fire protection charging device 1. For example, in heavy rain, water will enter the charging device, and the water level sensor 61 will send the monitored signal to the control board 10. When the water level is too high, the control board 10 will promptly disconnect the power supply and stop charging the battery pack, thereby reducing the impact of water accumulation on the battery pack and reducing the possibility of fire. Figure 3 As shown, the control board 10 can also supply power to the water level sensor 61 so that the water level sensor 61 can work normally.

[0060] Optionally, the water level sensor 61 includes a pressure water level sensor 61, an optical liquid level sensor or a non-contact capacitive liquid level sensor.

[0061] Combination Figure 2 and Figure 4 As shown, optionally, the fire protection charging device 1 further includes a heating system 62. The heating system 62 is disposed in the fire protection charging device body and connected to the control panel 10.

[0062] In low temperature environments such as winter, the ambient temperature of the charging equipment is low, and the battery pack is in a low temperature charging state, which will affect the life of the battery pack. Therefore, when the control board 10 receives a signal that the battery pack temperature is low, the heating system 62 can be turned on to heat the battery pack to solve the impact of low temperature charging on the life of the battery pack. Figure 3 As shown, the heating system 62 is also connected to the circuit protection device 42 and is powered by 220V AC.

[0063] Optionally, the heating system 62 includes heating wires or infrared radiation heating.

[0065] Compared with a low temperature environment, when the temperature of the environment in which the charging device is located is high, the charging compartment 70 needs to be cooled. By providing a first fan 631 in each charging compartment 70, when the temperature of the charging compartment 70 is high, the corresponding first fan 631 can be turned on to dissipate the heat of the charging compartment 70, thereby realizing the temperature control function of the charging compartment 70. In addition, a separate second fan 632 is also provided on the main body of the fire protection charging device to dissipate the heat of the main body of the fire protection charging device 1 according to the overall temperature of the fire protection charging device 1. Figure 3 As shown, the exhaust system 63 is also connected to the voltage converter 43 and is powered by direct current.

[0066] Combination Figure 2 and Figure 4 As shown, optionally, the charging compartment 70 includes a smart socket 31 and / or a composite detector 30. The smart socket 31 is disposed in the charging compartment 70 and is communicatively connected to the control panel 10 and the alarm main control platform 20. The composite detector 30 is disposed in the charging compartment 70 and is communicatively connected to the control panel 10.

[0067] The smart socket 31 is used to charge the battery pack and can communicate with the control panel 10 and the alarm control platform 20 through the CAN bus to exchange data and obtain the current charging voltage, current, power and other data of the battery pack in real time. The composite detector 30 is used to monitor the changes of various parameters of the charging equipment and send the detected data to the control panel 10 for fire determination. In addition, combined with Figure 4 As shown, a composite detector 30 is also provided on the fire protection charging device body for monitoring the overall situation of the fire protection charging device 1 .

[0068] Combination Figure 3 As shown, optionally, the smart socket 31 is connected to the circuit protection device 42 via a relay 66 and a second circuit breaker 67 .

[0069] In order to power the high-voltage circuit inside the smart socket 31, it is necessary to connect the smart socket 31 to a 220V AC power source. For all smart sockets 31, a relay 66 and a second circuit breaker 67 are set together to achieve unified control of all smart sockets 31, and centralized power-off protection of charging facilities in the event of a fire or system failure. An independent relay is set inside each smart socket, and communication is used to achieve switch control of the load power supply of a single smart socket. The implementation of the above method makes the charging equipment more intelligent and has the least wiring. In addition, combined with Figure 3 and Figure 4 As shown, the smart socket 31 is also provided with an indicator light 32, and the indicator light 32 is connected to the voltage converter 43 and is powered by direct current.

[0070] Combination Figure 5 As shown, optionally, the composite detector 30 includes a single-chip computer body 100, a power module 200, a temperature detection module 300 and a gas detection module 400. The power module 200 is connected to the single-chip computer body 100. The temperature detection module 300 is respectively connected to the single-chip computer body 100 and the power module 200. The gas detection module 400 is respectively connected to the single-chip computer body 100 and the power module 200.

[0071] Combination Figure 3As shown, the control panel 10 and the composite detector 30 exchange data and power the composite detector 30 through the two-bus technology to realize the internal monitoring of the charging device. In the composite detector 30, a temperature detection module 300 and a gas detection module 400 are provided, and the single-chip computer body 100, the temperature detection module 300 and the gas detection module 400 are powered by the power module 200. During the charging process of the fire protection charging device, the temperature change and gas change of the charging device are detected by the temperature detection module 300 and the gas detection module 400, and the detected changes are sent to the single-chip computer. The single-chip computer can realize real-time collection and calculation processing of the detected data based on the ARM (Advanced RISC Machine, Advanced Reduced Instruction Set Machine) processor to perform fire warning judgment. By combining multiple detection methods, the fire is warned according to the temperature and gas changes, so as to improve the accuracy of the composite detector 30 in fire warning.

[0072] Combination Figure 6 As shown, optionally, the power module 200 includes a two-bus circuit 201, a DC / DC circuit 202 and a voltage stabilizing circuit 203. The two-bus circuit 201 is connected to an external power supply. The DC / DC circuit 202 is connected to the two-bus circuit 201. The voltage stabilizing circuit 203 is connected to the DC / DC circuit 202.

[0073] In this implementation, the power supply module 200 is used to power each module in the composite detector 30. First, an external power supply is connected through the two-bus circuit 201, and a first voltage V1 is output after filtering and rectification. Then, the first voltage V1 output by the two-bus circuit 201 is converted into a stable second voltage V2 through the DC / DC circuit 202 to power the composite detector 30. Since the working power supplies of different modules in the composite detector 30 are different, it is necessary to design multiple voltage stabilizing circuits 203 in the circuit to provide different power supplies for power supply. In addition, the two buses also have a communication function. When the composite detector 30 detects a fire, the fire information can be reported to the control system of the fire protection charging equipment through the communication bus, and comprehensive judgment and system control can be performed.

[0074] Optionally, the value range of the first voltage V1 includes [22V, 26V]. More specifically, the first voltage V1 is 23V, 24V or 25V.

[0075] Optionally, the value range of the second voltage V2 includes [7V, 10V]. More specifically, the second voltage V2 is 7V, 8V or 10V.

[0076] Optionally, the voltage stabilizing circuit 203 includes a first voltage stabilizing circuit 213, a second voltage stabilizing circuit 223 and a third voltage stabilizing circuit 233. The first voltage stabilizing circuit 213 is connected to the DC / DC circuit 202. The second voltage stabilizing circuit 223 is connected to the DC / DC circuit 202. The third voltage stabilizing circuit 233 is connected to the second voltage stabilizing circuit 223.

[0077] In this embodiment, three different voltage stabilizing circuits are provided, and three different voltages are output according to the second voltage V2. Among them, the value range of the third voltage V3 output by the first voltage stabilizing circuit 213 includes [3V, 4V]. More specifically, the third voltage V3 is 3.3V, 3.5V or 3.7V. The value range of the fourth voltage V4 output by the second voltage stabilizing circuit 223 includes [4.5V, 5.5V]. More specifically, the fourth voltage V4 is 4.7V, 5V or 5.3V. The value range of the fifth voltage V5 output by the third voltage stabilizing circuit 233 includes [1.5V, 2V]. More specifically, the fifth voltage V5 is 1.5V, 1.8V or 2V.

[0078] Combination Figure 6 As shown, optionally, the temperature detection module 300 includes: an ambient temperature sensor circuit 301, a temperature and humidity sensor circuit 302, and a thermopile temperature sensor circuit 303. The power supply end of the ambient temperature sensor circuit 301 is connected to the first voltage stabilizing circuit 213, and the output end is connected to the single-chip computer body 10. The power supply end of the temperature and humidity sensor circuit 302 is connected to the first voltage stabilizing circuit 213, and the output end is connected to the single-chip computer body 100. The thermopile temperature sensor circuit 303 is connected to the second voltage stabilizing circuit 223 and the single-chip computer body 100, respectively.

[0079] In this embodiment, three different temperature sensor circuits are arranged in the composite detector 30 to detect temperature changes in different areas. The ambient temperature sensor is used to detect the change of the current ambient temperature. Since the ambient temperature will rise when a fire occurs, the change of the ambient temperature can be used to give a preliminary warning of the fire. The temperature and humidity sensor is used to detect the temperature and humidity on the surface of each sensor, and according to the detected temperature and humidity, a temperature and humidity error compensation algorithm is used to compensate for the measurement error of the sensor, and the detection result of the sensor is compensated and adjusted. In order to improve the accuracy of the detection result of the temperature and humidity sensor, the arrangement position of the temperature and humidity sensor also needs to avoid the heating unit on the circuit board. The thermopile temperature sensor is used to detect the temperature of the surface of the battery and the charger. During the charging process, if the detected temperature is greater than the set value, an alarm signal is issued, and the charging power supply of all charging compartments is cut off in conjunction. The third voltage V3 output by the first voltage stabilizing circuit 213 is used to power the ambient temperature sensor and the temperature and humidity sensor, and the fourth voltage V4 output by the second voltage stabilizing circuit 223 is used to power the thermopile temperature sensor, which can improve the detection accuracy of each sensor. In addition, for the ambient temperature sensor and the temperature and humidity sensor, two first voltage stabilizing circuits 213 may be provided to provide power, thereby achieving the independence of the ambient temperature sensor and the temperature and humidity sensor.

The carbon monoxide sensor circuit 401 is connected to the second voltage stabilizing circuit 223 and the single-chip computer body 100 respectively. The VOC gas sensor circuit 402 is connected to the second voltage stabilizing circuit 223 and the single-chip computer body 100 respectively. The power supply end of the smoke sensor circuit 403 is connected to the third voltage stabilizing circuit 233, and the output end is connected to the single-chip computer body 100.

[0081] In this embodiment, the gas detection module 400 needs to detect a variety of different indicators in the air, including carbon monoxide concentration, set gas concentration, and smoke concentration, which are important indicators for judging the occurrence of fire. The carbon monoxide sensor and the VOC gas sensor are powered by the fourth voltage V4 output by the second voltage stabilizing circuit 223, and the smoke sensor is powered by the fifth voltage V5 output by the third voltage stabilizing circuit 233. The thermopile temperature sensor, the carbon monoxide sensor, and the VOC gas sensor can also be powered by three second voltage stabilizing circuits 223 to realize the independence of the thermopile temperature sensor, the carbon monoxide sensor, and the VOC gas sensor.

[0082] The composite detector 30 provided in the embodiment of the present disclosure integrates a variety of fire detection technologies such as ambient temperature sensors, temperature and humidity sensors, thermopile temperature sensors, carbon monoxide sensors, VOC gas sensors and smoke sensors, and can perform three-dimensional fire monitoring of the entire charging process. The composite detector 30 provided in the embodiment of the present disclosure can be applied to charging and swapping facilities, and can also be adapted to other occasions with battery fire hazards. It mainly includes early fire warning before battery thermal runaway and mid-term fire alarm during thermal runaway. Disconnecting the power supply of the battery pack in time before the battery pack temperature and released gas reach a certain level can terminate the battery thermal runaway process and effectively reduce fires. In addition, connecting the composite detector 30 to the fire extinguishing system can also realize automatic fire extinguishing control after the fire alarm, thereby achieving the purpose of effectively controlling the fire.

[0083] Combination Figure 4 As shown, optionally, the charging compartment 70 also includes a door lock 72.

[0084] Combination Figure 3 and Figure 4 As shown, optionally, the fire protection charging device 1 further includes a camera 65, which is arranged on the fire protection charging device body and is used to obtain a real-time image of the fire protection charging device 1. The camera 65 is connected to the control board 10 and the battery charge and discharge management unit 51 respectively, and the camera 65 is powered by the battery charge and discharge management unit 51.

[0085] Combination Figure 2 and Figure 4 As shown, optionally, the fire protection charging device 1 further includes a fire extinguishing control system 64, which is communicatively connected to the control panel 10. The fire extinguishing control system 64 includes: a fire extinguisher, which stores fire extinguishing agent; a control valve assembly, including a total circuit control assembly and one or more single circuit control assemblies, which are communicatively connected to the control panel 10, the total circuit control assembly is connected to the fire extinguisher, and each single circuit control assembly is respectively connected to a charging compartment 70. Among them, the control panel 10 controls the fire extinguisher to spray the fire extinguishing agent by opening the total circuit control assembly and the single circuit control assembly corresponding to the charging compartment 70, so as to extinguish the fire in the charging compartment 70.

[0086] When the composite detector 30 of one of the charging compartments 70 sends out an alarm signal, the fire extinguisher can be controlled by the control valve assembly to spray out the fire extinguishing agent, thereby extinguishing the fire in the charging compartment 70. In addition, since some battery packs may re-ignite after being extinguished once, effective fire extinguishing can be achieved by performing the fire extinguishing process multiple times.
