36Kr has learned that recently, the fuse R & D and manufacturer "Super Fuse Technology" has completed a tens of millions of yuan Series B financing, exclusively invested by Renfa Investment. The funds from this round of financing will be mainly used for market expansion, capacity expansion, and the research and development of high-end new products such as Pyrofuse Instantaneous Interrupter.

"Super Fuse Technology" was established in 2018, focusing on the medium and high-end market of fuses in the new energy power system. Its products cover the new energy vehicle, charging pile, wind power, photovoltaic energy storage, and electric ship fields. It has dozens of product series and hundreds of product specifications, and is committed to providing circuit protection solutions for various new energy high and low voltage power supplies, power distribution systems, control systems, and electrical equipment.

Circuit protection devices are key components to ensure the safe and stable operation of the power system, and they play a crucial role in various electrical and electronic devices. Fuses are a type of circuit protection device that plays the role of overload and short-circuit protection in the circuit. When the current abnormally rises and exceeds the safety threshold, the fuse will quickly cut off the circuit to avoid damage to electrical equipment or catastrophic events such as fires.

In the field of new energy vehicles, the application of fuses is crucial. They are used to protect key components such as battery packs, motor controllers, and on-board chargers, ensuring that these components can be powered off in time in the event of overload or short circuit, thereby protecting the safety of the entire vehicle's electrical system. In addition, in the energy storage system, fuses also play an important role. They protect energy storage battery packs, inverters, and confluence equipment, preventing equipment damage caused by circuit faults, and ensuring the stable operation of the energy storage system and the effective management of energy.

With the rapid development of new energy technologies, the performance requirements for fuses are also getting higher and higher. They not only need to respond quickly but also need to work stably in various complex environments.

Data from Markets and Markets shows that the global high-voltage fuse market size was $1.6 billion in 2020. Driven by the demand in fields 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 of 5.8%.

At present, the global circuit protection device market is mainly occupied by some international large companies, such as Littelfuse, Eaton, Schurter, Mersen, etc., and foreign fuse brands account for more than 80% of the global market share.

However, there are some pain points in the existing fuse products on the market. First, the response time of traditional fuses is relatively slow. Facing the rapidly changing current, they cannot respond in time, which may lead to the inability to effectively protect the circuit in extreme cases. Secondly, traditional fuses will generate more heat during continuous operation, which not only reduces the energy efficiency of the system but also may affect the service life of the equipment. In addition, the cost of traditional fuses in high-voltage and high-current systems is relatively high, which poses a certain economic pressure for large-scale applications.

In response to these pain points, the products of "Super Fuse Technology" have carried out innovations and improvements in these aspects. Dai Chao, the CEO of "Super Fuse Technology", introduced that their Pyrofuse Instantaneous Interrupter adopts advanced technology and can cut off the circuit almost instantly (within 1 millisecond) when the current abnormally rises. This fast response ability far exceeds that of traditional fuses, greatly improving the safety of the circuit. At the same time, the Pyrofuse Instantaneous Interrupter focuses on low power consumption in the design, reducing the heat generated during operation. This not only improves the energy efficiency of the system but also helps extend the service life of the equipment.

36Kr has learned that in terms of cost control, especially in high-voltage systems above 1000V, the Pyrofuse Instantaneous Interrupter of "Super Fuse Technology" adopts a unique arc extinguishing method and an optimized circuit design, while its traditional fuses adopt an innovative melt solution and modular design to achieve lower material costs and higher production efficiency.

In addition, the product line of "Super Fuse Technology" can meet the needs of different application scenarios from small electric tools to large-scale energy storage systems. Specifically, it has a variety of models. The Pyrofuse Instantaneous Interrupter series includes multiple series such as SPF-1 to SPF-6. These products consider compatibility and universality in the design and can seamlessly interface with the existing circuit protection system. For example, for charging piles, new energy vehicles, and energy storage systems, the Pyrofuse Instantaneous Interrupter can provide the same installation size and overall dimensions as the original traditional fuses, facilitating replacement and upgrading.
