Battery energy storage moving to higher DC voltagesFor improved efficiency and avoided costsThe evolution of battery nergy storage systems (BESS) is now pushing higher DC voltages in utility scale applications. The Wood Mackenzie Power & Renewables Report is forecasting phenomenal growth
The scheme of the high-voltage DC power supply Based on the proposed solution, the primary task of the input stage is to serve as a regulating circuit for the input voltage of the battery pack (V bat) with a rated voltage of 32 V and the intermediate voltage (V dc ≈ 320 V).
In an AC-Coupled PV and energy storage solution (pictured in Figure 1, left side), both inverters employed can push power and can absorb or supply reactive power at the same time. The AC-Coupled system can produce peak PV power at the same time as the bi-directional inverter is discharging the full battery power to the grid.
The power supply is powered by a 32 V lithium battery pack with high energy storage density, boosted to about 400 V through the intermediate stage of a non-isolated DC-DC boost converter, and then connected to an isolated phase-shifted full-bridge DC-DC converter, outputting a high voltage of 50 kV.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
