Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle safety monitoring, and in particular to an electric vehicle charging area safety early warning system. Background Art

[0002] With the development of society, traffic congestion and environmental pollution are becoming increasingly serious. Electric vehicles have begun to become the travel choice of most people, especially for short-distance trips within cities. As the electric vehicle industry has sprung up like mushrooms after rain, various problems of uneven quality have also arisen, especially for the core components of electric vehicles, batteries. Unqualified batteries are very likely to cause hazards such as spontaneous combustion. Even for qualified batteries, care must be taken when charging them to prevent damage caused by excessive charging.

[0003] Due to the guidance of the current government and the awareness of residents, for users living in buildings, electric vehicles will be charged in the charging area designated by the community property. However, when the existing electric vehicle chargers are charging the electric vehicle batteries, most electric vehicles do not have an automatic power-off function. In the actual charging process, when the battery is full, the electric vehicle charger will not stop charging by itself, but will continue to output a low trickle current to the battery. Although a small amount of trickle current will not have much effect in a short period of time, if this state is maintained for a long time, it will cause floating charge to the battery. If this continues for a long time, it will cause serious water loss and affect the battery life. If the battery life is shortened, quality problems will occur. When a battery explodes due to a malfunction, other batteries in the charging area where it is located will cause a chain explosion, causing great harm. However, today's residential communities or office buildings do not have devices or systems for safety monitoring of all electric vehicles in the charging area, and there are safety hazards. Summary of the invention

[0029] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0030] like Figure 1As shown, an electric vehicle charging area safety warning system described in the present invention includes an environmental detection module for real-time monitoring of environmental parameters in the electric vehicle charging area. The electric vehicle charging area refers to the location range of the electric vehicle when it is in the charging state, which can be in a residential area or in an office building. The environmental parameters collected by the environmental detection module include environmental temperature signals and smoke signals in the electric vehicle charging area. There are several environmental detection modules distributed in the electric vehicle charging area to perform signal monitoring on various positions in the electric vehicle charging area. The environmental detection module transmits the collected data to the control module. The control module is used to process the environmental parameters collected by the environmental detection module and to monitor the charging status of the charging pile in real time, such as the current, voltage, or power consumption during charging, to ensure that when an abnormality occurs in the circuit, the control module obtains the abnormal signal as soon as possible. The charging pile is used to supply power to the electric vehicle. The charging pile or the charger can be used to charge the electric vehicle, as long as it can charge the electric vehicle and achieve the effect of cutting off the power supply control. The charging pile is located in the electric vehicle charging area. When charging a motor vehicle, an environmental detection module and a charging pile are connected to a control module. The environmental detection module monitors the environmental parameters in the electric vehicle charging area in real time and transmits them to the control module. The control module processes the environmental parameters, and there is a built-in threshold range in the control module. This threshold range is a safety threshold range. If this threshold is exceeded, the control module determines that the collected data information is abnormal. The control module processes the environmental parameters according to the detection and judgment strategy. The control module compares the collected data signal with the threshold parameter in the control module. The control module controls the switch of the power supply of the charging pile according to the judgment result. The control module is also connected to a data server, and the data server is connected to a Web server. The control module transmits the processed environmental parameters and the charging status of the charging pile to the Web server through the data server for storage. There are several charging piles, each of which is equipped with a control module. Several control modules transmit their processed environmental parameter data to the data server for aggregation. The user terminal remotely checks the charging safety status of the electric vehicle charging area by downloading data from the Web server.

[0031] The determination method of the detection and determination strategy is as follows:

[0032] S1, the environmental detection module monitors the environmental parameters in the electric vehicle charging area in real time;

[0033] S2, the environmental detection module transmits the collected environmental parameters to the control module;

[0034] S3, inputting the safety threshold range into the control module;

[0035] S4. The control module compares the input environmental parameters with the safety threshold range. If the environmental parameters are within the safety threshold range, the charging pile continues to charge the electric vehicle. If the environmental parameters are not within the safety threshold range, the control module immediately cuts off the power supply of the charging pile to protect the safety of the electric vehicle.

[0036] Embodiment 1:

[0037] The environmental detection module includes a smoke and temperature sensor and a regional temperature measurement module. Both the smoke and temperature sensor and the regional temperature measurement module are arranged in the electric vehicle charging area for real-time monitoring of temperature signals and smoke signals. There are several smoke and temperature sensors and regional temperature measurement modules, which are evenly distributed in the electric vehicle charging area. Both the smoke and temperature sensors and the regional temperature measurement modules are existing monitoring modules. As long as they can achieve the purpose of monitoring temperature and smoke, in addition, the environmental detection module can also have the function of monitoring other environmental signals, such as the pressure of the electric vehicle battery, the position of the electric vehicle, the charging current of the battery, etc.

[0038] The control module in this embodiment is a smart socket, which also serves as a data communication gateway. The smart socket is arranged at the charging interface of the charging pile. The charging pile charges the electric vehicle through the smart socket. The smart socket monitors the current and power consumption in the charging pile in real time. The data signal collected by the environmental detection module is also transmitted to the smart socket, which processes the data. The smart socket belongs to the existing technology and can display data on it. It can also monitor the current of the charging pile and the circuit in the system. If the current suddenly increases, it is determined that an abnormality has occurred, and the power supply of the charging pile is cut off to protect the safety of the electric vehicle.

[0039] In this embodiment, since there are a large number of environmental detection modules, the environmental detection module communicates wirelessly with the control module through LoRa signals, which saves wiring space and realizes intelligent data transmission. The control module forms a data transmission channel with the data server through NB-IOT or wired, and data transmission can be performed wirelessly or wired.

[0040] Furthermore, the control module also includes an alarm module, which is used to issue an on-site alarm when the environmental detection module monitors that the environmental parameters reach the threshold of the control module, and transmit the alarm signal to the user terminal through the data server.

[0041] In specific implementation, the electric vehicle charging area in this embodiment is a cone. If the installation height of the regional temperature measurement module is 2.5 meters, the monitored area is 3*6 square meters. This is taken as an example to illustrate the installation height and monitoring range of the regional temperature measurement module. The regional temperature measurement module automatically reports the temperature values ​​of the five points with the highest temperature measurement values ​​among the temperature measurement points to the control module, that is, the smart socket. The smart socket processes the collected temperature values ​​and the current and power values ​​of the charging pile, and compares them with the built-in threshold range. When a sudden increase in current is detected or an alarm is received from the environmental detection module, the smart socket will immediately and automatically cut off the total power supply of the charging pile, and at the same time send an alarm to the user terminal through the data server to remind the user to avoid further expansion of the harm.

[0042] The present invention installs a plurality of smoke and temperature sensors and regional temperature measurement modules in the electric vehicle charging area of ​​a residential area or an office building, which actually monitor the temperature signal and smoke signal in the charging area in real time and transmit them to the control module. The control module monitors the charging current and power consumption of the charging pile in real time, and compares the collected data with the internal threshold value. If the safety threshold value is exceeded, the charging pile is controlled to be powered off, and an alarm signal is remotely transmitted to the user terminal through the data server to remind the user, thereby minimizing the possibility of harm, and the data server can summarize the monitoring data of several charging piles in one electric vehicle charging area, and can also summarize the monitoring data of charging piles in several electric vehicle charging areas, thereby effectively avoiding the occurrence of dangerous accidents during the charging process of electric vehicles.

[0043] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
