Description
It is widely applied in the following scenarios: such as fuel cell power generation, energy storage, storage and charging, photovoltaic storage and charging, storage and charging inspection, battery secondary utilization energy storage, vehicle-to-grid interaction V2G and other multi-energy complementary scenarios. With high-frequency isolation between input and output, it is the preferred product for the energy bidirectional flow application industry
Product Features:
- More secure and reliable:
- Full high-frequency isolation design ensures the safety between the battery and DC bus.
- Full digital control with DSP+CPLD, featuring multi-level software and hardware protection against overcurrent, overvoltage, and over-temperature, ensuring safety and reliability.
- Reliable parallel connection function facilitates power expansion, allowing up to 16 modules to be connected in parallel.
- Higher efficiency:
- DC/DC employs soft-switching resonant technology, achieving a maximum efficiency of 97%.
- Compared to traditional non-isolated DC/DC systems, the high-frequency isolation efficiency in this system is higher, reaching over 97%, eliminating the need for a line frequency transformer in system applications.
- More intelligent and user-friendly:
- Covers multiple battery voltage levels (40V~300Vdc) for passenger vehicles, with a wide battery voltage range.
- Wider DC bus voltage for easy connection to various DC bus specifications.
- Lower cost:
- Compared to traditional bidirectional power supply solutions, high-frequency isolation eliminates the need for a line frequency transformer, reducing system cost.
- Achieves both charging and inverting functions through a single circuit, integrating charging and discharging, resulting in lower costs.
- More flexible configuration:
- Supports standard rack-mounted installation with a compact structure.
- Module hot-swappable design for flexible system configuration.
- Facilitates system integrators in flexibly designing different forms of energy storage, photovoltaic storage, energy storage inspection, or energy storage systems.
