In recent years, due to the growth of renewable energy and its increasing grid connection share, the power grid has gradually evolved from a traditional centralized and large-scale power supply model to a distributed structure spread across various regions. However, the intermittent nature of green energy has increased the demand for flexible dispatch and stability in the power grid.
To enhance grid stability and achieve a more flexible power architecture, the role of the Bidirectional Power Supply has evolved from simple power conversion to the core of energy asset dispatch. It is a core technology for realizing V2G (Vehicle-to-Grid), microgrids, and residential energy storage grid connection, as shown in Figure 1.
In an era where energy usage logic is being rewritten, the Bidirectional Power Supply is no longer an optional feature, but an essential component for transforming electricity from a “consumable” to an “asset.”

Figure 1. Application of Bidirectional Power Supply
MEAN WELL’s newly released BIC-5K series Bidirectional Power Supply complies with the international grid-connected power generation equipment standard IEC 50549-1, possessing the key performance characteristics required for grid stability:
- Rapid switching
- High efficiency and energy saving
- High voltage support
- Flexible expansion
- Smart communication
- Ultimate safety
The BIC-5K Bidirectional Power Supply offers three operating modes: BIC bidirectional mode, grid-connected mode, and charging mode.
BIC Bidirectional Mode
In this operating mode, the BIC-5K is a standard single-unit high-power bidirectional power supply that automatically detects voltage and switches current direction. It can also switch as needed via external signals or CAN Bus/Modbus communication.
Grid-Connected Mode
In this operating mode, based on the IEC 50549-1 standard, the BIC-5K is not only a bidirectional power supply but also part of a distributed energy resource (DER).
Charging Modes
The BIC-5K is not simply a standalone high-power charger. In addition to adjusting the 2-stage/3-stage charging modes and charging curve values via communication, it can also be used in conjunction with grid connection mode.
