Product Overview
- 10kV high-voltage direct connection: the high-voltage line enters the enclosure directly, reducing intermediate distribution equipment and making the system more compact.
- Multi-pulse phase shifting: a phase-shifting transformer improves the rectifier power take-off and reduces harmonic impact on the grid.
- SiC active rectification: actively corrects the current waveform while supporting reactive power compensation and power quality management.
- High-efficiency DC/DC: rapidly adjusts output according to vehicle battery voltage to improve DC conversion efficiency.
- Dynamic power distribution: 2 ultra-fast and 4 fast charging terminals flexibly share power, reducing idle charging guns.
- Integrated prefabrication: high voltage, transformation, power conversion and control are integrated to shorten on-site construction.
Product Features
Megawatt-Level Ultra-Fast Charging
System power reaches 2.5MW with 1500A liquid-cooled ultra-fast charging terminals, delivering high-power rapid charging for heavy trucks, mining trucks and large electric equipment.
Up to 96.5% System Efficiency
System efficiency reaches 96.5%, effectively reducing energy loss under high-power continuous charging conditions.
2 Ultra-Fast + 4 Fast Charging Terminals
Equipped with 2 × 1500A liquid-cooled ultra-fast terminals and 4 × 250A air-cooled fast terminals, with flexible power distribution based on vehicle and site load demand.
THDi ≤ 3%
Phase-shifting transformers, multi-pulse rectification and power electronics work together to limit THDi to within 3%, meeting power quality requirements for high-power charging equipment.
Fast Station Deployment
Prefabricated, integrated design means on-site work mainly involves high-voltage connection and charging terminal wiring, greatly reducing conventional distribution room construction and commissioning. Typical build time can be shortened to 7–14 days.
Reduced Footprint
High-voltage incoming line, transformer, power conversion and control systems are highly integrated, eliminating a separate conventional distribution room and reducing site equipment footprint by about 40%.
