[Application Fields]
Optical storage and Charge or Storage and Charge multi-energy complementary application
Multi-energy complementary application scenarios, such as large charging stations or change stations, "optical storage and charging" or "storage and charging" integrated charging stations make use of clean energy power supply, through photovoltaic power generation after the storage of electrical energy, photovoltaic, energy storage and charging facilities formed a micro-grid, according to the demand of the public grid intelligent interaction, and can achieve grid-connected, off-grid two different modes of operation. The use of energy storage system can also alleviate the impact of charging pile on regional power grid when charging with high current; Cut the peak and fill the valley to earn the electricity price difference.
The use of common DC bus power supply scheme, photovoltaic, energy storage, charging pile, DCDC load, etc., reduce ACDC conversion links, reduce investment costs, and improve system efficiency.
Storage and charge inspection, use to discharge new energy vehicles or battery packs, check the battery capacity, and calculate the degree of battery capacity attenuation.
Vehicle mobile energy storage
The mobile energy storage vehicle is loaded with a large-capacity battery. The DCDC module can realize various application scenarios such as charging the vehicle and supplying DC load.
The electric vehicle can supply power to DC load through the DCDC module to realize electric vehicle energy storage V2L.
Parallel balanced control of UPS battery pack
Medium and high-power UPS is usually connected in parallel with multiple groups of batteries, each battery is connected to the DCDC module,when the consistency between battery packs is poor, the DCDC module adjusts by boosting and balancing,control the current balance between the battery packs, suppress the circulation between the battery packs, ensure the UPS and the battery system to work reliably, and extend the battery life.
