1. Overview of the Two-Wheeled EV Charging Station Industry
1.1 Industry Background
As an important short-distance travel tool for urban and rural residents in China, the number of electric bicycles has exceeded 400 million and continues to grow by tens of millions annually. However, along with this rapid increase in ownership comes an increasingly serious charging safety issue. Many electric bicycle users, due to the lack of public charging facilities in residential communities, office buildings, and other places, are forced to push their bikes into corridors, parking garages, and even indoors to charge, which seriously violates fire safety regulations. Electric bicycle batteries carry risks of overheating and overcharging during charging. Once spontaneous combustion occurs, fires spread quickly in enclosed spaces, easily causing serious mass casualties.
Since 2021, the Ministry of Emergency Management, Ministry of Public Security, and other departments have successively introduced policies prohibiting electric bicycles from being brought into buildings and homes for charging, while mandating the promotion of centralized charging models. Local governments have vigorously promoted the construction of centralized charging facilities in communities and business parks, creating huge market demand for two-wheeled electric vehicle charging stations. IoT smart charging stations have become core infrastructure for addressing electric bicycle charging safety issues, with the market size expanding rapidly.
1.2 Definition of Smart Charging Stations
Two-wheeled electric vehicle smart charging stations are public charging facilities specifically designed for electric bicycles, electric motorcycles, and other two-wheeled electric vehicles. They are equipped with intelligent functions such as multiple independent charging channels, QR code payment, overcharge protection, smoke alarm, and remote monitoring. Compared with ordinary household outlets, smart charging stations effectively prevent the risk of battery overcharge and spontaneous combustion through precise charging control and safety protection mechanisms; they enable centralized management and remote operation via Internet of Things connections, offering a safe and standardized alternative to wiring privately and charging in hallways.
2. Core Pain Points of Electric Bicycle Charging Safety Issues
2.1 Risk of Spontaneous Combustion Due to Battery Overcharging
During the charging process of electric bicycle lithium batteries, if the charger is of poor quality, the battery is aging, or charging is improperly controlled, overcharging may occur. Overcharging generates a large amount of heat inside the battery, leading to thermal runaway, which can cause electrolyte vaporization, battery swelling, fire, and explosion. A large number of cheap electric vehicles on the market are equipped with low-quality chargers that lack overcharge protection, posing a significant safety hazard. Users often have the habit of charging at night, without supervision; if a fire breaks out and detection is delayed, it can easily result in a major accident.
2.2 Too few chargers, and the illegal habits stick
Residential compounds and business parks still have far too few chargers. Riders who cannot find a socket fall back on illegal charging. A property ban on stairwell charging has little force when there is nowhere else to go and the ban is hard to enforce. Building a charger means agreeing a site, a power feed, the money, and who will run it. That coordination is slow, so the gap between supply and demand lasts.
2.3 Early chargers were little more than a socket strip
The first two-wheeler chargers were mostly a row of sockets, with no management on them. Status cannot be seen from afar, so a fault shows up only when a rider complains. There is no way to stop a non-standard charger. The bill is opaque and arguments follow. The hardware wears out fast and costs a lot to keep. There is no operating data to add up, so nobody can tell whether the site earned its keep.
3. Core applications of IoT technology in two-wheeler EV charging stations
3.1 Multiple safety protection mechanisms
The safety protection of smart charging stations is a core function. The charging power monitoring module continuously monitors the charging current and voltage; once it detects that the battery is fully charged (charging current drops below the threshold) or the charging time exceeds the preset limit, it immediately cuts off the power to prevent overcharging at the source. Smoke detectors are integrated into the top of the charging station or charging shed. Once smoke is detected, while triggering audible and visual alarms, all power to the charging station is immediately cut off to maximize control of a fire. Temperature sensors monitor temperature rise during charging and automatically cut off power in case of abnormally high temperature to prevent equipment overheating and safety incidents.
Lightning and surge protection ensure the safe operation of the charging station during thunderstorms; waterproof rating IP44 or above allows for outdoor deployment; anti-theft alarm protects charging cables and prevents equipment damage. Each charging socket is independently controlled, and the failure of one does not affect other users' normal charging, improving service reliability.
3.2 Convenient Charging and Multiple Payment Methods
QR code charging is the mainstream usage method. Users scan the QR code on the charging station with WeChat or Alipay, choose the charging duration (usually 0.5 hours, 1 hour, 2 hours, etc.) and pay; the system automatically activates the corresponding socket to start charging. After charging is completed, power is automatically cut off, and any unused charging time fees are refunded. NFC/IC card charging suits older riders: they top up a card and do not need a smartphone. An app adds the member features, including history, prepaid package top-ups, and a remote look at whether the bike is still charging.
3.3 IoT Remote Monitoring and Management
Each charging station connects to the cloud operation management platform through a built-in 4G/NB-IoT module, reporting device status, charging records, and fault information in real time. Operators can check key data such as the online rate of all charging stations in the jurisdiction, the status of each charging port, and daily revenue in real time via the Web or APP backend. Abnormal situations such as device offline, socket failure, and smoke alarm will push alert notifications for timely response and handling by maintenance personnel. The remote control function allows operators to remotely turn on or off specific charging stations or charging ports without on-site visits, significantly reducing operation and maintenance costs.
3.4 Operational Revenue and Business Model
The business models for two-wheel charging stations usually include self-operation by property management, operation by third-party operators, or revenue-sharing between property and operators. Time-based billing (ranging from 0.1-0.5 yuan per hour) is the mainstream charging mode, while some areas charge based on electricity consumption. Operational data is totaled as it happens, and the money settles itself, with no one standing there to collect cash. Monetization through advertisement screens is an additional revenue source, with the LED screen on top of the charging station displaying nearby business ads to increase non-charging income. Analysis of device operation data helps operators understand the return on investment for each location, guiding subsequent site selection and investment decisions.
4. Characteristics of IoT Technology for Two-Wheel Charging Stations
4.1 Selection of Communication Technology
The selection of communication technology for two-wheel charging stations needs to comprehensively consider factors such as network coverage, power consumption, cost, and data volume. 4G IoT SIM cards are currently the most widely used solution, offering wide coverage, high speed, and low latency, suitable for charging station applications that require real-time communication; SimtoLink provides IoT SIM cards optimized for charging station scenarios, supporting major carriers nationwide, with stable signals and reasonable rates. NB-IoT is suitable for low-power applications with small data volume and low real-time requirements, but its real-time response capability is weak. WiFi is suitable for indoor scenarios with stable network coverage, but its reliability is lower for outdoor installations.
4.2 Hardware Protection Design
Outdoor charging stations face harsh environmental challenges such as high temperatures, severe cold, humidity, and direct sunlight, making protection level and reliability crucial. The charging station housing is made of engineering plastics or metal materials, resistant to UV aging, high and low temperatures; the charging cables use thickened rubber insulation jackets, wear-resistant and bend-resistant; the connector is reinforced and rated for at least 5,000 mating cycles. Charging stations used in northern regions need heating modules to ensure normal operation in low-temperature environments; insect screens are designed to prevent insects from entering the equipment and causing short circuits.
5. Industry Development Trends
5.1 The Rise of the Battery Swap Model
The battery-swapping model is a new direction for energy replenishment for two-wheeled electric vehicles. Users place a depleted battery into a swapping cabinet and take out a fully charged one. The whole process takes no more than one minute, completely solving the time cost problem of "waiting to charge." The charging management system inside the swapping cabinet precisely controls the charging process of each battery, extending battery life and ensuring safety. IoT technology supports remote management, battery tracking, and settlement systems for the swapping cabinets. Food delivery and express riders work long shifts, so they are the best fit for swapping. As swap standards line up, the model will spread further.
5.2 Integrated solar-charging shed
A photovoltaic charging shed combines rooftop solar photovoltaic panels with EV charging stations to achieve on-site generation and consumption of clean energy. The electricity generated from photovoltaics is directly supplied to the EV charging stations, and any surplus is fed into the grid; when photovoltaic power is insufficient, it automatically switches to the grid supply. An integrated solar-charging shed not only meets the sheltering needs against wind and rain but also reduces electricity costs for charging, improving the economic efficiency of charging investment. As photovoltaic costs continue to decline, integrated solar-charging sheds will become an important choice for new charging shed constructions.
