Features

Bidirectional power module Safer and more reliable
Full high-frequency isolation design to ensure the safety between the battery and the grid/load; Battery-friendly, battery grouping access, reduce battery series and parallel connection, avoid battery circulation problems, and extend battery life; Compatible with different manufacturers and different characteristics of batteries grouped into the DC side of the module; It is grid-friendly, and the AC side is connected in parallel, showing the characteristics of a single machine.

Bidirectional power module more efficient
The battery is isolated from the power grid at high frequency, eliminating the need for power frequency transformers, and the high frequency isolation efficiency is higher, as high as 95%.

Bidirectional power module smarter and more friendly
Cooperating with STS module, it can realize seamless switching between on and off grid; Covers multiple battery voltage levels for passenger cars (40V~750Vdc), with a wide battery voltage range.

Lower cost
Compared with traditional modular energy storage, high-frequency isolation saves power frequency transformers and indirect costs (cabinet, fan, etc.), and the system cost is low; Through a set of circuits, two functions of charging and inversion are realized, charging and discharging are integrated, and the cost is low.

More flexible configuration
Module hot swap design, flexible system configuration; According to requirements, it can be flexibly configured into energy storage converters with different power levels and battery voltage levels.

Bidirectional power module application Field 
Energy storage (cascade utilization of batteries)
The product is a modular energy storage converter, which is very suitable for decommissioning or the use of old power batteries as energy storage. The power covers 15kW~250kW, which is suitable for energy storage in industrial and commercial parks. Flexible embedded PCS solution provides core PCS module, which is convenient for system integrators to flexibly design different forms of energy storage systems; isolated bidirectional AC/DC converters are safer, more efficient, and more bulky when connected to batteries small; With the STS module, after the grid is powered off, it can be switched to off-grid power supply, which is suitable for microgrid (island, remote villages, etc.) scenarios; wide voltage range, very suitable for retired power battery echelon applications; can be configured as mobile energy storage, suitable for G20 Important power supply scenarios such as summits, Boao Forum, and college entrance examinations.

Battery formation and separation
Figure 2 shows the solution of bidirectional high frequency isolation power supply for battery formation and capacity division. The battery pack is grouped into the module, eliminating the power frequency transformer, and the system is more efficient and smaller in size.

DC power aging
DC power supply, such as charging pile module, power operation power supply, communication power supply, etc., during production aging, if there is a resistive load or electronic load, huge power loss will be generated; if the DC power supply is connected to the V2G module during the aging process, the power Feeding back to the grid will save at least 95% of the electricity, save the owner's electricity bill, and save the owner's production cost.
