Customized new energy charging station | Design power/appearance/function according to demand · Match special scenarios

With the rapid growth of the number of new energy vehicles, the demand for charging facilities has extended from "basic coverage" to "precise adaptation". There are significant differences in power requirements, appearance styles, and functional configurations of charging piles among different user groups in different scenarios, such as residential communities, commercial centers, highway service areas, industrial parks, tourist attractions, etc. Standardized products are difficult to fully meet personalized needs. Customized new energy charging pile solutions have emerged, which have become a key way to improve charging experience and optimize resource allocation by flexibly designing power parameters, appearance and functional modules, accurately matching the usage requirements of special scenarios.

1、 Why do we need customized charging stations? Differences in scenarios give rise to diverse demands

 The charging behavior of new energy vehicle users is closely related to the characteristics of the scenario, and the core demands for charging piles vary significantly in different places, which is the fundamental reason for the emergence of customized demand.

1. Power demand: the span from daily power replenishment to rapid energy replenishment

 Residential community scenario: Private cars are mainly charged slowly at night, and car owners are more concerned about charging safety and electricity cost. They usually choose 7kW (AC slow charging) or 11kW (AC medium speed charging) charging piles to meet the demand for 8-12 hours of full charging and avoid overloading household circuits.

• Commercial complex/office building scenario: Users have a short stay time (such as 2-4 hours) and need to "stop and charge, quickly recharge". They prefer charging piles with 120kW-180kW (DC fast charging), which can replenish 50% -80% of their electricity during parking, reducing waiting anxiety.

• Highway service area scenario: Users have extremely high requirements for charging timeliness (usually staying for no more than 30 minutes), requiring equipment with 300kW-480kW (overcharging pile) or even higher power, combined with battery fast charging technology to achieve emergency energy replenishment of "10 minutes to 40%".

Industrial parks/logistics scenarios: Commercial vehicles such as electric heavy-duty trucks and logistics vehicles have large battery capacities (with a single battery capacity of over 200kWh), requiring customized high-power DC piles of 350kW-600kW or multi station solutions that support "dual gun charging" and "alternating charging" to meet high-frequency and high power charging needs.

2. Appearance requirements: Functional aesthetics that integrate with the environment

 High end residential/villa areas: Users pay attention to the coordination between charging piles and building appearance, and tend to prefer simple white, matte metal texture designs, or customized wooden/stone decorative shells that match the villa style, or even hidden installations on garage walls to maintain overall aesthetics.

Cultural and tourism attractions/historic districts: It is necessary to avoid the modern industrial feel of charging stations from damaging the landscape atmosphere. Antique wood grain shells, low saturation color schemes (such as green gray, beige), or landscape ornaments (such as incorporating street lamp posts and rest pavilions) may be used.

Gas station/convenience store scenario: The charging station needs to be consistent with the existing facility style, such as matching the blue/red brand color scheme of the gas station, or designed as a compact wall mounted device, saving space and not interfering with normal business operations.

3. Functional requirements: Additional value in special scenarios

 Low temperature environment (northern region): It is necessary to integrate a battery heating module (preheat the battery to a suitable temperature through a charging station), or equip it with an insulated charging gun cable to avoid charging power attenuation and prolonged charging time caused by low temperature.

• High humidity/salt spray environment (coastal areas): The casing should adopt a waterproof and dustproof design of IP65 or above, the internal circuit should be coated with moisture-proof material, and the charging gun cable should be made of corrosion-resistant material to prevent short circuits caused by seawater erosion.

• Areas without network coverage (remote scenic spots/mountainous areas): It is necessary to support offline payments (such as card swiping, scanning codes to store transaction records locally), localized billing systems (without relying on cloud servers), and ensure normal use even in weak signal environments.

Shared charging scenario (community public parking spaces): It is necessary to integrate intelligent recognition functions (distinguishing between car owners and non car owners through license plate recognition and user app binding), support scheduled charging, timely billing, and remote management (property management can view charging status and restrict unauthorized use).

2、 Core design elements of customized charging stations

Customization is not simply "parameter adjustment", but a systematic design based on user needs, focusing on three dimensions: power, appearance, and functionality, while also considering safety, compatibility, and ease of maintenance in the future.

1. Science and flexibility in power design

 Power selection needs to comprehensively consider the user's vehicle type, power grid carrying capacity, and usage scenario characteristics. For example, the distribution capacity of residential communities is usually limited (the capacity of a single household electricity meter is mostly 4-8kW). If an 11kW charging pile is directly installed, it may cause a trip. In this case, the "power divider" or "intelligent orderly charging" technology (dynamically adjusting the output power according to the grid load) can be used to maximize the utilization of existing circuits while ensuring safety.

For commercial scenarios, it is necessary to evaluate the number of vehicles charging simultaneously and the peak power demand. For example, in a parking lot with 20 parking spaces, if all 120kW DC piles are installed, the theoretical peak power demand is 2400kW. However, in actual use, it is rare for all vehicles to be charged at full power at the same time. Therefore, the "time-sharing power sharing" design (such as controlling the total distribution capacity at 1000kW and dynamically allocating single pile power according to the number of vehicles connected) can be used to reduce the initial cost of power transformation.

In addition, the customization of high-power charging stations also requires matching with the vehicle's battery management system (BMS). For example, some early electric vehicle models only support a maximum charging power of 100kW, and even if a 200kW charging station is installed, higher speeds cannot be achieved. In this case, the "power adaptive" function of the charging station (automatically identifying the maximum power supported by the vehicle and adjusting the output) is needed to avoid resource waste or equipment conflicts.

2. Scene adaptation of exterior design

The appearance design of the charging station needs to meet both functional and aesthetic requirements. Structurally, wall mounted charging piles are suitable for residential garages or narrow parking spaces with limited space, while floor standing charging piles are more suitable for open public parking lots; From a material perspective, outdoor scenes should use rust resistant aluminum alloy or 304 stainless steel shells, paired with UV resistant PC panels (to prevent discoloration caused by sunlight exposure); From the perspective of the interactive interface, commercial scenarios can add LED displays (displaying charging progress, costs, and advertising information), while residential scenarios focus more on a simple operation panel (retaining only necessary buttons and indicator lights).

Examples of customized appearance for special scenarios include:

Hospital parking lot: The charging pile shell is coated with antibacterial material (to reduce bacterial growth), and the color is soft light blue or green to alleviate the anxiety of patients and their families;

Campus scene: designed in cartoon style or combined with school emblem elements to reduce students' sense of distance from charging facilities, while increasing anti misoperation protection (such as child lock function);

Gas station renovation project: The appearance style of the charging station and the fuel dispenser is unified (such as the same brand color and line design), and even a charging station installation position is reserved next to the fuel gun, forming a comprehensive energy supply station with "complementary oil and electricity".

3. On demand expansion of functional modules

The functions of customized charging stations can be flexibly stacked according to scene requirements, and common expansion modules include:

• Smart payment module: support WeChat/Alipay code scanning, NFC (touch by phone), IC card swiping and other payment methods, and even connect enterprise accounts (such as unified settlement by fleet management companies);

Energy management module: linked with photovoltaic panels and energy storage batteries (such as commercial rooftop photovoltaic power generation prioritizing charging piles), or through V2G (vehicle to grid) technology, the vehicle battery's electrical energy is reverse transmitted to the grid during peak hours to earn profits;

• Safety monitoring module: integrates smoke alarm, over temperature protection sensor, and leakage detection device. Once an abnormality is detected (such as overheating of the charging gun or vehicle battery failure), the power is immediately cut off and an alarm is pushed to the management background;

User experience module: Provides charging reservation function (locking charging stations in advance through the APP), charging completion reminder (SMS/APP push), remote fault diagnosis (operation and maintenance personnel check device status through the background to reduce on-site troubleshooting time).

3、 Implementation process and key links of customized charging stations

The implementation of customized projects requires deep collaboration between users and service providers. The entire process from requirement communication to installation and operation needs to clarify key nodes to ensure that the final product meets both personalized requirements and safety and quality standards.

1. Requirement research and scheme design

 The service provider first communicates with the user about specific scenario characteristics, including the type of charging vehicle (private car/commercial vehicle/special vehicle), daily charging capacity, peak usage period, existing power conditions (such as distribution capacity, line direction), and site spatial layout (such as parking space size, installation location orientation). For example, a parking lot in a certain scenic area wishes to install charging stations, but there is no fixed power grid access point in the area. The service provider needs to evaluate the feasibility of solar power supply and energy storage batteries; A certain logistics park needs to charge electric heavy-duty trucks, and it is necessary to confirm the vehicle battery capacity and charging interface standards (such as whether it is a GB/T 20234.3 DC interface).

Based on the research results, the service provider provides a preliminary design plan, including power configuration (single pile power and total power), appearance style (color, material, size), function list (basic charging+expansion module), installation method (wall mounted/floor standing/column mounted), and estimated cost. The plan needs to balance user needs and practical feasibility - for example, if a user wishes to install a 600kW supercharging pile, but the site's distribution capacity only supports 300kW, power adjustment or power expansion needs to be carried out first.

2. Technical validation and prototype testing

 For customized solutions with special requirements (such as low-temperature heating modules and V2G functions), service providers need to conduct technical verification: by simulating extreme environments in the laboratory (such as -20 ℃ low-temperature charging and high humidity environment operation), testing the stability and safety of the equipment; For exterior design, create a 1:1 physical model or 3D printed sample to confirm whether the size ratio, ease of operation, and visual effects meet expectations. For example, a high-end community requires charging piles to be installed in a hidden manner on the garage wall. The service provider has made an embedded prototype to verify its connection technology with wall decoration materials (such as gap sealing and cable hiding methods).

3. Manufacturing and Quality Control

 The production of customized charging stations must strictly follow industry standards (such as GB/T 18487.1-2015 "Electric Vehicle Conductive Charging System Part 1: General Requirements"), while meeting the special parameter requirements of users. During the production process, key components such as charging modules and control motherboards need to undergo aging tests (simulating long-term operating conditions), and the shell material needs to pass weather resistance tests (such as high-temperature 80 ℃ and low-temperature -40 ℃ cycling tests) to ensure long-term use in different environments without failure.

4. Installation, debugging, and after-sales operation and maintenance

The installation process needs to be operated by professional personnel to ensure the electrical connection safety of the charging station (such as grounding resistance<4 Ω, insulation resistance>1M Ω), and stable network communication (such as 4G/5G signal coverage or local Wi Fi backup). During the debugging phase, various customized functions need to be tested, such as whether the smart payment module can deduct fees normally, whether the scheduled charging function is accurately triggered, and whether the low-temperature heating module can preheat the battery to above 5 ℃ in a -10 ℃ environment. In terms of post operation and maintenance, service providers need to provide regular inspections (such as checking the aging status of lines every quarter), remote fault diagnosis (real-time monitoring of equipment status through IoT platforms), and rapid response mechanisms (such as telephone guidance within 2 hours and on-site maintenance within 24 hours).

4、 The future trend of customized charging stations: from single devices to scenario based solutions

With the increasing penetration rate of new energy vehicles, charging facilities will shift from "standardized product supply" to "scenario based service integration". The future customized charging piles will not only be charging tools, but also energy nodes deeply integrated with the scene, presenting the following trends:

Deep linkage with energy management systems: Charging piles will become an integral part of the building/park energy network, coordinating the charging needs of photovoltaic power generation, energy storage batteries, and electric vehicles through intelligent algorithms, achieving "peak shaving and valley filling" (reducing electricity costs) and "low-carbon energy supply" (reducing dependence on fossil fuels).

• More flexible deployment mode: For temporary scenarios such as exhibitions and construction sites, a mobile customized charging station (integrated with a generator or energy storage battery) is launched, which can be quickly installed and used after being transported to the site by trailer; For high-frequency mobile scenarios (such as around taxi swapping stations), deploy "shared power pool" charging stations (where multiple vehicles share total power and dynamically allocate charging resources).

User participation in design co creation: Through online platforms, users can participate in the appearance voting of charging stations (such as selecting colors and patterns), customize functions (such as whether voice broadcasting or lighting prompts are needed), and even open up some technical parameters (such as power adjustment range) to make the devices more tailored to individual needs.

From power to appearance, from function to scenario, customized new energy charging piles are breaking the limitations of "one size fits all" and providing more solid infrastructure support for the popularization of new energy vehicles by accurately adapting to the needs of different users. Whether it's one click convenient charging in residential communities, high-speed energy replenishment on highways, or reliable operation in special environments, customized solutions are redefining the meaning of "charging freedom" with flexibility and professionalism.
