As new energy vehicles enter millions of households, charging piles are growing increasingly vital as "energy refueling stations". The charging module, which accounts for over half of the total equipment cost, directly determines charging experience and safety through its performance and reliability. Surging market demand and continuous technological upgrades have made testing requirements for charging modules more complex and stringent.

Leveraging industry leading expertise in power electronic circuit design, Jingce independently developed the new generation JN807 Series Programmable DC Electronic Load. Boasting robust performance including high precision measurement, high power density and modular design, it serves as an ideal testing partner for the R&D and production of charging modules. It provides customers with safe, efficient and accurate testing solutions for new energy charging pile modules,

helping them cut costs, boost efficiency and improve yield rates.

01 Full-coverage Core Functions | High precision Measurement

Through high speed closed-loop circuits and ARM+FPGA software algorithms, the JN807 Series realizes power control and precise measurement monitoring. It accurately supports basic modes including Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV) and Constant Power (CP), as well as extended functions such as dynamic load variation and short?circuit simulation, fully complying with standard testing items.

Equipped with a 16 bit high precision A/D converter and a voltage current sampling rate of 1 microsecond per cycle, it precisely captures subtle changes such as output response time. Customizable load waveform visualization makes test data more intuitive.

02 High Power Density: Compact Size, High Performance

Charging pile modules are growing more powerful, while testing equipment must remain space efficient.

03 Modular Design for Easy Maintenance & Upgrade

04 Flexible Capacity Expansion for Diverse Testing Needs

With larger capacity batteries and faster charging rates for new energy vehicles, charging module power is evolving from 30kW to 60kW and 80kW, making expandability a key requirement for testing equipment.

Highly adaptable, the JN807 Series supports master slave control and rapid parallel connection via external cascade terminals for multi?load parallel testing, reaching a maximum power of 500?kW. It covers testing requirements for mainstream and future high power modules with industry?leading power ratings. Flexible expandability greatly improves equipment utilization and application scope.

As a high?power DC electronic load integrating high precision, high performance and high power density, the JN807 Series plays a vital role in multiple industrial application scenarios with its comprehensive functions and excellent adaptability.
