At around 4 a.m. on February 23, a major fire accident occurred in Mingshang Xiyuan, Yuhuatai District, Nanjing, killing 15 people. According to preliminary analysis, the fire was caused by illegal charging of electric bicycles on the elevated floors of six buildings.

Another safety accident involving electric bicycle charging is very sad.

With the popularity of electric bicycles, more and more people choose to use electric bicycles as a travel tool. However, what follows is the frequent occurrence of electric bicycle charging safety accidents, which poses a great threat to the safety of people's lives and property. According to statistics from the National Fire and Rescue Bureau, a total of 21,000 electric bicycle fires were reported across the country in 2023, an increase of 17.4% compared to 2022. The frequent fire accidents and the rising trend have once again attracted attention on the safety issues of electric bicycles.

 Causes of electric bicycle charging safety accidents

1. Illegal charging

For convenience, many electric bicycle users plug in power sources in residential areas, stairwells, etc. for charging. This behavior can easily cause fires. In addition, some users push electric bicycles into elevators and charge them in high-rise buildings, which is also a very dangerous behavior.

2. The charger is unqualified

Some electric bicycle users buy substandard chargers for charging in order to be cheap. Spontaneous combustion caused by various reasons, such as lack of ventilation, exposure to the sun, high ambient temperature, inability to intelligently cut off power, and lack of flame-retardant materials on the casing.

3. Charging time is too long

The battery of an electric bicycle produces hydrogen and oxygen during the charging process. If the charging time is too long, the battery may overheat and cause a fire.

As mentioned above, problems such as users' personal behavior and mismatched batteries will bring safety risks to wired charging of electric bicycles.

Wireless charging: protect cycling safety and make charging more secure

Wireless charging is a safer and smarter charging method that realizes wireless transmission of electric energy through the principle of magnetic resonance. When the motorcycle is parked in the charging area, the system will automatically identify and charge it. This technology has the characteristics of high efficiency, stability, and safety, and provides reliable technical guarantee for the safe charging of motorcycles.

As a leading company in the domestic wireless charging field, Zhonghui Chuangzhi has also paid attention to the safety issues of electric bicycle charging. Based on magnetic resonance wireless charging technology and IOT Internet of Things platform, Zhonghui Chuangzhi spent two years investing millions in R&D funds and successfully launched it. For the intelligent wireless charging management system for electric two-wheelers, wireless charging does not cause direct physical contact with current, that is, it does not cause risks such as wear and electric shock. The built-in powerful chips and algorithms can adapt to specific battery voltages and can be used through the IOT system. Real-time monitoring of the charging status; not only that, the charging action is very convenient, realizing magnetic stop-and-go charging. It avoids the risk of electric shock caused by wired charging and reduces the risk of fire caused by poor contact. In addition, since there is no direct contact with metal wires during wireless charging, safety hazards caused by friction and collision are reduced.

At present, intelligent wireless charging management systems for electric two-wheeled vehicles have been successfully implemented in batches, including magnetic suction, shared unattended motorcycle wireless charging systems and campus shared scooter wireless charging systems. Currently, these two two-wheeled vehicle projects have been implemented domestically. It has been implemented in batches in many regions and universities, and has been praised by local operators and users.

Zhonghui Chuangzhi also uses this article to express its condolences to the victims. May the deceased rest in peace and the living be alert. Learn lessons from electric bicycle fire accidents, popularize wireless charging technology for electric bicycles as soon as possible, and create a safe and reliable environment for charging electric bicycles while riding.
