1. Observe the indicator light of the charging pile: during normal operation, the indicator light should show the corresponding state, such as the power indicator light is always on, the charging indicator light flashes, etc. If the indicator light does not light up, flashes abnormally, or displays an error code, there may be a problem.
2. Check the display (if any): check whether the display can normally display charging information, such as voltage, current, charging time, etc. If the display screen is black, colorful, or disordered, it may be abnormal.

• Timeshare:
  • Peak hours (such as daytime working hours, etc.): different regions of the peak electricity price is different, generally per kilowatt-hour electricity may be from 0.8 - 1.8 yuan or even higher.
  • Peak hours (e. g. off-peak hours on normal working days, etc.): usually around 0.5 - 1.5 yuan per kilowatt-hour.
  • Low period (e. g. night, etc.): the lowest price, can be as low as 0.3 - 0.9 yuan per degree of electricity, etc.
• Single electricity price: some charging piles (especially some old ones or those that are not connected to the power grid for their own use) may be charged at a fixed electricity price such as 0.5 - 1 yuan/degree.

The charging speed of the DC pile is much faster. The common DC pile power is 30kW, 60kW, 120kW or even higher. For example, using a 60kW DC pile to charge an electric vehicle with the above 50kWh battery capacity may only take about 50 minutes to fully charge.

1. Have a fixed parking space: This is the basis for installing the charging pile to ensure that the charging pile has a suitable installation location.
   • For example, your own garage, parking space, or a long-term lease and a parking space licensed by the property.
2. Power conditions: The power supply line and capacity that can meet the power demand of the charging pile are required near the parking space.
   • For example, some of the old community may be insufficient power capacity, the need for power capacity.
3. Comply with safety standards: the installation position cannot affect the fire passage, there can be no flammable and explosive materials, etc., and must comply with relevant safety regulations.

1. Electrical safety

The charging pile power supply is generally connected from the standby switch of the power supply in the power distribution room, and the capacity does not exceed the total capacity of the power supply. It is separated from the lighting circuit of residential users and will not affect the normal power consumption of users.

2. Fire safety

The location of charging piles shall meet the requirements of fire safety and be far away from flammable, explosive, pollution and other dangerous sources. The shell and internal connector of the charging pile are made of flame retardant materials to meet the fire protection requirements. The protection device of the charging pile cooperates with the upper power protection device to form protection. When the charging line is overloaded during the charging process of the vehicle, the overload protection in the charging pile will trip in time, disconnect the power supply, and isolate the fault. When the charging pile body or the line between the charging pile and the power distribution room is overloaded, the power switch will trip, disconnect the power supply in time, avoid accidents, and ensure that users can charge safely.

Charging car charging pile is universal in general, but it needs to meet certain conditions.

General Conditions and Standards

Comply with national standard:

Electric vehicles and charging piles must meet national standards. Since 2015, five national ministries and commissions have jointly issued five national standards for electric vehicle charging interfaces and communication protocols (referred to as GB 2015), which will be formally implemented on January 1, 2016. These standards focus on the safety and compatibility of charging piles.

Since then, in order to further improve the technical level and safety of charging facilities, the state has issued new standards, such as GB/T 18487.1-2023 and GB/T 27930-2023, which were issued on September 7, 2023 and formally implemented on April 1, 2024.

Supply voltage requirements:

The power supply voltage of the charging pile should match the charging demand of the electric vehicle. For example, AC charging piles with a capacity of less than 7kw usually use 220V single-phase AC, while AC charging piles with a capacity of more than 7kw use 380V three-phase AC.

Generality Description

When both the electric vehicle and the charging pile meet the above national standards and the power supply voltage and other conditions match, they can be used universally. This means that car owners can charge their electric vehicles on different brands of charging piles, provided that these charging piles follow the same national standards.

Special circumstances

Although most charging piles are universal, there are still some special cases. For example, certain brands or models of electric vehicles may have special charging interfaces or communication protocols, which may prevent them from charging on certain charging piles.

Alternatively, due to regional differences and different grid conditions, some charging piles may need to be appropriately modified or adjusted to meet the charging needs of specific electric vehicles.

In addition, it does not rule out the problem that some piles cannot be charged due to software problems and do not match the cars of other manufacturers, or the charging will be cut off occasionally. In addition, imports such as Tesla will not be universal. The most common problem is the communication protocol. Many charging piles or electric vehicles are not fully implemented in accordance with the national standard, so there will be places in the protocol that cannot be intercommunicated, resulting in no match.

Conclusion

In summary, charging car charging piles are universal in most cases, but the premise is that they must meet national standards and match the power supply voltage and other conditions. At the same time, car owners should also pay attention to the existence of special circumstances to ensure that their electric vehicles can be charged smoothly on charging piles of different brands.

No, it's not. Due to the limited power of the car battery during the charging phase, when the output power of the DC charging pile reaches a certain upper limit, the larger power will not bring faster charging speed. Therefore, the significance of the high-power DC charging pile is that it can support dual connectors and output high power at the same time to charge two electric vehicles at the same time. In the future, when the electric vehicle battery is improved to support higher power charging, you can consider investing in upgrading the charging station again.

The higher the output power of the charging station, the faster the charging speed, but this conclusion is affected by many factors.

Relationship between 1. output power and charging speed

Proportional relationship:

Generally speaking, the charging output power is proportional to the charging speed. High output power means that more power can be transferred to the electric car battery in the same time, so the charging speed will be faster.

Example Description:

The output power of the DC charging pile is usually much higher than that of the AC charging pile. For example, the output power of the DC charging pile can reach 60kW to 120kW, while the output power of the AC charging pile is generally between 3.5kW and 21kW. Therefore, when charging with DC charging piles, the charging speed of electric vehicles will be significantly faster than that of AC charging piles.

2. other factors that affect the charging speed

Although the output power is an important factor affecting the charging speed, it is not the only factor. Here are some other factors that can affect charging speed:

electric car battery capacity:

An electric vehicle with a larger battery capacity will take longer to fully charge at the same output power.

Charging interface and communication protocol for electric vehicles:

The charging interface and communication protocol of electric vehicles need to match the charging pile, otherwise it may affect the charging speed.

Charging voltage and current of electric vehicles:

The charging interface of an electric vehicle has a set input voltage and current, and the charging voltage and current of the charging pile cannot exceed the upper limit of the charging interface of the electric vehicle. Therefore, electric vehicles of different brands and models will have different charging speeds.

Battery level:

Generally speaking, the lower the battery power, the faster the charging speed; the higher the battery power, the slower the charging speed. This is because the battery management system of electric vehicles will adjust the charging power according to the battery status to protect the battery from damage.

Battery temperature:

Battery temperature is too high or too low will affect the charging speed. In the optimal temperature range (usually 10°C to 30°C), the battery can obtain the fastest charging speed.

Simultaneous use of other electrical equipment:

If other electrical equipment of the electric vehicle (such as air conditioning, audio, etc.) is used at the same time during the charging process, the charging speed may be reduced.

3. Conclusion

In summary, the higher the output power of the charging station, the faster the charging speed. However, this conclusion is affected by many factors, including the battery capacity of the electric vehicle, the charging interface and communication protocol, the battery power level, the battery temperature, and whether other electrical devices are used at the same time. Therefore, when choosing a charging station, in addition to considering the output power, other factors need to be comprehensively considered to ensure the best charging experience.

Precautions

In the actual charging process, it is recommended that the owner choose the appropriate charging method and charging time according to the actual situation of the electric vehicle and the conditions of the charging station.

At the same time, in order to extend battery life and improve charging efficiency, it is recommended that car owners check the battery status before charging and follow the charging guidelines of electric vehicle manufacturers.
