Recently, fuse manufacturer Chauron Technology completed a multi-million RMB Series B financing round, with exclusive investment from Renfa Investment.
The funds raised will be primarily used for market expansion, capacity expansion, and the R&D of high-end products such as Pyrofuse instant circuit breakers.
Founded in 2018, Chauron Technology specializes in mid-to-high-end market of fuse products for new energy power systems, serving applications in EVs, charging piles, wind/solar/storage systems, and electric vessels.
The company offers dozens of product series and hundreds of specifications, providing circuit protection solutions for various new energy high and low-voltage power sources, distribution systems, control systems, and electrical equipment.
Circuit protection devices are essential for the safe and stable operation of power systems, playing a crucial role in electrical and electronic devices. A fuse, a type of circuit protection device, safeguards against overloads and short circuits.
When current exceeds safe levels, the fuse quickly disconnects the circuit, preventing damage to equipment and minimizing the risk of hazards such as fires.
In the new energy vehicle sector, fuses are vital for protecting key components such as battery packs, motor controllers, and onboard chargers.
They ensure these components are safely disconnected during overloads or short circuits, safeguarding the vehicle’s entire electrical system. Fuses also play a crucial role in energy storage systems by protecting battery packs, inverters, and combiner boxes, preventing damage from circuit faults and ensuring stable operation and efficient energy management.
As new energy technologies develop rapidly, the performance demands for fuses are increasing. They must respond quickly and operate stably in various complex environments.
According to Markets and Markets, the global high-voltage fuse market was valued at $1.6 billion in 2020. Driven by demand from sectors such as new energy vehicles, smart grids, and solar power generation, it is expected to reach $2.2 billion by 2025, with a compound annual growth rate (CAGR) of 5.8%.
Currently, the global circuit protection device market is dominated by major international companies like Littelfuse, Eaton, Schurter, and Mersen, with foreign fuse brands accounting for over 80% of the global market share.
However, existing fuse products in the market face several challenges. Traditional fuses often have slower response times and may fail to react quickly enough to rapidly changing currents, compromising protection in extreme conditions.
Furthermore, they generate significant heat during continuous operation, reducing system efficiency and potentially shortening the lifespan of equipment. Additionally, traditional fuses are costly in high-voltage, large-current systems, posing an economic burden for large-scale applications.
To address these challenges, Chauron Technology has introduced innovative solutions. Dr. Dai Chao, CEO of Chauron, explains that their Pyrofuse instant circuit breakers utilize advanced technology to interrupt circuits within 1 millisecond of detecting abnormal currents, offering significantly faster response times than traditional fuses and greatly enhancing circuit safety.
Additionally, Pyrofuse breakers are designed for low power consumption, reducing heat generation during operation, improving system efficiency, and extending equipment lifespan.
In terms of cost control, Chauron Technology’s Pyrofuse utilize unique arc-quenching methods and optimized circuit designs for high-voltage systems above 1000V. Meanwhile, its traditional fuses feature innovative fuse element solutions and modular designs, achieving lower material costs and higher production efficiency.
Chauron’s product line meets the needs of various application, from small power tools to large-scale energy storage systems. Specifically, the Pyrofuse series includes various models such as SPF-1 to SPF-6. These products are designed with compatibility and versatility, allowing seamless integration with existing circuit protection systems. For example, in charging stations, new energy vehicles, and energy storage systems, the Pyrofuse matches the installation and external dimensions of traditional fuses, simplifying replacements and upgrades.
In addition to Pyrofuse and high-performance DC traditional fuses, Chauron Technology offers customized solutions for various industries, such as the SMC fuse, an innovative product designed for two-wheel electric vehicles and power tools.
With its compact design and efficient performance, the SMC provides an economical and convenient circuit protection solution for users.
Chauron has established strong partnerships in the new energy vehicle sector with companies like CATL, GOTION HIGH-TECH, serving major automakers such as SAIC MOTOR, CHERY, and GEELY.
In the wind and solar energy storage sector, Chauron offers protection solutions for inverters, combiner boxes, battery packs, high-voltage boxes, and PCS, serving clients like SUNGROW and CATL. In the charging station sector, Chauron collaborates with numerous companies, including StarCharge and XJ Group to ensure reliable operations.
Internationally, Chaoron’s products are supplied to leading clients such as BORGWARNER and TATA Group, with exports to Europe, the Middle East, and Southeast Asia.
As the CEO of Chauron Technology, Dr. Dai Chao brings extensive research experience in circuit protection and new energy power systems. The company’s team also brings years of R&D expertise in the fuse and automotive industries.
Investor Insights: Zhao Chaoyun, Investment Director at Renfa Investment, believes that Pyrofuse have significant growth potential as new energy vehicles and high-voltage fast charging continue to expand.
Chauron Technology has a highly experienced R&D team, leading technological advantages, and a solid customer base. The company is consistently advancing in both the fuse and Pyrofuse. With support from investors like SUNGROW, Chauron is in a strong position to achieve rapid growth in the near future.
