New national standards implemented: Safety upgrade, wireless charging technology exempted from policy

In January 2024, the State Administration for Market Regulation officially released the "Electric Bicycle Electrical Safety Requirements" (GB 4296-2022), which explicitly prohibits the design, manufacture, and use of on-board chargers (Clause 4.3), aiming to eliminate safety hazards such as leakage and short circuit caused by vibration and plugging in traditional charging methods. It is worth noting that the standard clearly points out that "wire chargers are not applicable" in the "Output Interface Safety" section (5.5.6-5.5.8), which for the first time recognizes the and compliance of non-contact charging technology at the national level, and opens up policy channels for the promotion of wireless charging technology.

Core interpretation of the policy:

·Technological exemption: Wireless charging is exempted from the restrictions of in-vehicle chargers due to its non-contact nature, allowing the end to be flexibly designed as either external or integrated with the vehicle;

·Safety-oriented: All charging devices must undergo mandatory tests such as water resistance, shock, and overvoltage protection, and meet the battery mutual recognition and coordination protocol (verifying battery parameters before charging).

As a national-level "small giant" enterprise, Zhonghui Chuangzhi, with its more than 260 independently-owned intellectual patents and its technical accumulation from participating in the formulation of international standards, has taken the lead in launching a wireless charging system that is compatible with all scenarios, achieving high degree of alignment with the new national standards at the technical level.

Technical Adaptation: Full-link Compliance, Creating a New National Standard Benchmark Solution

1.Non-contact charging architecture, eradicating traditional safety hazards

Zhonghui Chuangzhi uses coupled magnetic resonance wireless power supply technology, which transmits electricity through electromagnetic waves without contact, completely avoiding physical risks of plug-and-play charging. Its system consists of a transmitting end (charging pile) and a receiving end (vehicle end), and the receiving end can be to external designs (such as kickstand type) or integrated designs developed jointly with car manufacturers (embedded in the frame, chassis).

Key compliance parameters:

·Electrical safety: IP67 grade water and dust proof, working temperature -20℃~50℃, passed the full item of GB 42296-2022; u

·Intelligent protection: threefold protection of overvoltage, overcurrent and overheating, charging up to 83%-95%, support 4A large current fast charging;

·Protocol recognition: bidirectional communication between the receiving end and the battery,-time verification of voltage and current parameters, eliminate compatibility risks.

2.Multi-scene solutions, covering civil and public needs

Community scenario: wall-mounted/standing magnetic charging pile, directly connected to 220V household power, supports seamless installation and intelligent billing;

site: ground-embedded transmitting end, supports "drop-and-charge" and one-to-many charging, a single control cabinet can connect 10 transmitting piles, the use of space resources;

Automotive cooperation: jointly develop vehicle-integrated receiving ends with electric bicycle manufacturers to achieve a "seamless charging" experience

Social value: Safeguarding the foundation, activating the potential of a trillion-level market

1.Crack down on people's livelihood pain points and guard public safety

According to statistics, the number of electric bicycles in China has exceeded 400 million, but traditional charging methods have caused more than 2,000 fire accidents per year (such as the major fire incident in Nanjing on February 24, 2024). Zhonghui Chuangzhi's wireless charging system, through zero-contact charging, intelligent monitoring, and full-enclosure protection, eliminates the hidden dangers of private wiring and batterycharging from the source, and provides safe infrastructure support for communities, scenic areas, and industrial parks.

2.Driving industrial upgrading and empowering smart cities

·Economic benefits: With a base of 350 million existing electric vehicles, if one charging pile is configured for every two vehicles, the market size exceeds 430 billion yuan;

·Management upgrade: Real-time collection of charging data, battery health status, and user behavior through the IoT cloud platform provides data support for urban travel planning;

·Green transformation: Reduce the land occupation of traditional charging facilities by 30%, and adapt to the needs of intensive urban construction under "double carbon" goal.

Authoritative endorsement: Technological leadership, standard guidance 

Based on the largest wireless charging R&D team in China (more than 50 people) and the top industry expert, Dr. Li Linghanrecipient of the special government allowance), Zhonghui Chuangzhi has achieved:

·Technological breakthrough: The world's first company to master the full power range of 1W-40kw magnetic resonance wireless power supply technology with a charging distance of up to 50cm;

·Standard participation: Led the drafting of several national standards related to wireless charging technology, promoting Chinese solutions to the;

·Large-scale implementation: Built intelligent production bases in Shenzhen and Fuyang, with an annual production capacity of over a million units, serving more than 40 industry scenarios.

Conclusion: Take the national standard as the outline, and technology as the wings

The promulgation of GB 42296-2022 marks a new stage of standardization and intelligence in the safety electric bicycle charging. With policy compliance as the cornerstone, technological innovation as the engine, and social value as the guide, Zhonghui Chuangzhi's charging system not only provides the optimal solution for the industry under the new national standards, but also drives the high-quality development of China's new energy transportation system with a-wheel drive of "safety intelligence".
