Is it safe to install charging piles at gas stations?

Since the launch of new energy vehicles, the growth rate of new energy vehicles has been increasing. Now many domestic gas stations are also focusing on developing multi-energy sources. So investors have been worried about one issue:

1. Is it safe to install charging piles at gas stations?

1) Heat dissipation and capacity expansion

The summer temperature in our country is often relatively high, and in this case, box-type substations working outdoors often generate a large amount of heat energy.

The box-type substation is small in size and makes it difficult to dissipate heat. The internal radiator has a poor heat dissipation effect, causing its temperature to greatly exceed its normal operating temperature range, which can easily cause safety accidents.

2) Equipment quality and operation and maintenance aging

The quality of relevant equipment varies and there is a lack of real-time operation and maintenance management methods. If a failure occurs, it will affect the safe operation of the distribution network.

3) Flooding problem

Box-type substations are mostly installed in outdoor environments, and most are installed in relatively flat areas following charging stations. Once heavy rains, urban waterlogging, etc. occur, the ensuing flooding problem will bring great safety and Hidden danger.

2. Hidden dangers of charging piles

1) Use electric shock

It is worth noting that the charging guns of some charging piles also pose great safety risks.

Some charging piles start supplying power before the charging gun is plugged into the car for charging,

and the voltage can reach more than 750 volts, but the relevant information is not displayed in time to inform the user.

In other words, if the user removes the charging gun with bare hands at this time, arc burns may occur, resulting in electric shock injuries.

In severe cases, the person cannot escape the situation and will be directly shocked to death.

2) Heavy rain

The national standard for electric vehicle charging piles also puts forward clear requirements for waterproofing. When electric vehicle charging piles are installed outdoors, the outdoor level of the electric vehicle charging pile must not be lower than the IP54 protection level. Among them, waterproofing and moisture-proofing are something that must be strictly paid attention to when charging piles for outdoor electric vehicles. If the outdoor protection level of the electric vehicle charging pile does not meet the standard and water stains appear inside the electric vehicle charging pile. The body of the electric vehicle charging pile has become seriously affected by moisture, which will affect the normal operation of the electric vehicle charging pile and problems will occur on the display screen of the electric vehicle charging pile. , exacerbating the risk.

3) Collision and dumping

In addition, the guardrails on the street are occasionally hit by vehicles. If an abnormal event occurs at the charging pile, what is its power-off function? During production, it is necessary to use shock-proof and impact-resistant charging pile potting compound to fill the internal gaps. It has flame-retardant and heat-conducting properties and plays a role in shock-proof and impact resistance. Therefore, it is necessary to study charging piles with dumping, shut down, and power-off functions based on using charging pile potting glue to avoid secondary electric shock injuries to personnel due to accidental collisions.

4) Outdoors in disrepair

In addition, untimely maintenance of charging piles also affects the safe use of charging piles. Charging piles installed outdoors will face various complex environments. For charging piles installed outdoors, in addition to preventing water from entering the interior, metal parts must also be prevented from rusting, increasing the risk of electric shock during use.

5) Charging pile spontaneous combustion

In summer, the weather is hot, and electric vehicle charging piles and electric vehicles are in a high-consumption state. It is very easy for guns to misfire and cause overheating and combustion accidents. To ensure public transportation safety, and vehicle and personal safety, electric vehicle charging piles must continuously improve their safety protection level.

3. Electric leakage accidents caused by vehicle failure

  • During the use of electric passenger vehicles, the basic insulation inside the vehicle charger may wear out due to external reasons such as bumps, causing the insulation level between the live part of the charger and the vehicle chassis to decrease or the components of the charger itself to be damaged.
  •  When the vehicle is non-charging since the charger is not working and is not connected to external charging facilities, this type of insulation failure will not affect the normal use of the vehicle.
  •  When the vehicle is charging, when the vehicle with internal insulation failure is connected to the external AC power supply, the insulation failure point of the charger will form a conductive path through the protective line (PE) and power line connected to the vehicle, and the charging facility will feel There are two types of fault currents: overload or short-circuit current and ground (residual) fault current. If charging is implemented without PE wires and good grounding protection, or if people encounter a faulty vehicle at this time, the risk of electric shock will come.
  • Through cloud computing, big data, the Internet of Things, mobile Internet, and other technologies, the self-developed RAMEVA8 multi-channel intelligent data collection and sensing measurement terminal is used to continuously monitor the operating status data of the power transformation and distribution equipment of the charging pile box substation 24/7. Flexible realize business needs such as comprehensive perception, real-time analysis, and proactive operation and maintenance of the charging pile power distribution system. It can effectively predict and provide alarm notifications for potential safety hazards caused by box-type transformers due to leakage, overload, three-phase imbalance, flooding, etc., thereby improving the safety and reliability of power distribution in the entire charging station and minimizing risks. By building a multi-dimensional sensing edge intelligence algorithm model, the platform conducts in-depth mining and analysis of physical, electrical, environmental, spatial, and other data, finds common problems hidden in large-scale data, and discovers weak links in distribution network planning and operation inspection. , and put forward targeted risk control and optimization strategies to reduce non-stop losses, eliminate hidden risks, optimize energy efficiency, and improve power supply quality. From economic benefits to risk management to orderly charging, comprehensively improve the comprehensive operating capabilities of charging facilities.
