In the new energy era, batteries are everywhere, and so are chargers. Safe and fast charging is a core concern of society. Kingpan Co., Ltd. officially launches the new generation of gallium nitride chargers for two-wheeled vehicles with lead-acid batteries - S250. Equipped with the company's independently developed variable-frequency square-wave patented technology, it redefines the electric vehicle charging experience with the core advantages of "safer, more cost-effective, and more efficient".

1. Technical Breakthrough - Variable-frequency Square-wave, 20% Increase in Battery Life
   The S250 charger adopts Kingpan Co., Ltd.'s exclusive variable-frequency square-wave intermittent safe and fast charging theory for lead-acid batteries (Patent No.: ZL.201210295561.X). By intelligently adjusting the current waveform, it significantly improves charging efficiency and battery performance:
   • Increase Battery Capacity: Compared with ordinary chargers, the S250 can release 20% more power. The single-cycle charge and discharge increases the capacity by 16.7% - 20.3%, helping groups such as food delivery riders and commuters to greatly extend their daily driving range.
   • Prolong Battery Life: The lead-acid battery life is extended by 100 - 150 cycles, with a battery life of ≥ 500 cycles, an extension of about 35% (traditional charging is 300 - 400 cycles). This effectively slows down the attenuation of battery capacity and reduces the long-term battery replacement costs for users.
   • Safe and Fast Charging: On the premise of ensuring safety, the charging speed is optimized. It can be fully charged in 4 hours, and the battery does not overheat, bulge, or emit gas, reducing potential safety hazards and users' waiting time.
2. Core Advantages - Safety First, Benefit for the People
   As the main product of Kingpan Co., Ltd., the S250 focuses on the real needs of users:
   • Safety Protection: It is equipped with triple protection mechanisms against overcharging, overcurrent, and short circuits. The whole process is digitally controlled, and it provides full protection in case of charging abnormalities, eliminating the risk of charging fires, which is especially suitable for the high-frequency food delivery industry.
   • Economical and Practical: It provides industrial-grade quality at an affordable price, truly achieving "one-time investment, long-term savings".
   • Wide Compatibility: It is compatible with mainstream 48V lead-acid battery electric vehicles on the market. Its important parameter is "48V 4A", and its performance is stable and reliable.
3. Social Benefits: Increase the income and reduce the burden of ordinary workers, and promote the superposition of social benefits. For example, for food delivery riders' 1000Wh two-wheeled vehicles (48V/20AH):

About Kingpan Co., Ltd.
         Guangzhou Kingpan Industrial Co., Ltd. is a national high-tech enterprise and a leader in safe and fast charging technology. It has focused on the research and development of electric vehicle charging technology for 33 years. It is a specialized and innovative small company in the field of safe and fast charging for storage batteries. It has more than 50 core patents, and its products are sold well in Europe, America, South Korea, Japan, Russia, and China, with over 2,000 customers.

The core of the variable-frequency square-wave technology is the "four synchronizations", moving forward in unison.

Throughout the charging process, it always maintains the dynamic synchronization of the positive electrode reaction, negative electrode reaction, ion migration, and electron migration, ensuring full charging within micro - time intervals.
