MEAN WELL BIC-5K – 5kW Grid-Tied Bidirectional AC⇄DC Power Supply for Energy and V2G Applications

Rising energy costs and the global transition toward low-carbon solutions are accelerating demand for energy recovery and storage systems. The new MEAN WELL BIC-5K expands the proven MEAN WELL BIC-2200 family, delivering higher power for industrial and grid-tied applications.

With a rated power of 5,000W, the BIC-5K enables efficient bidirectional AC⇄DC energy conversion, supporting both battery charging and energy recovery back to the grid.

True bidirectional energy management

The BIC-5K supports:

• AC → DC conversion for battery charging,
• DC → AC conversion for feeding recovered energy back to the grid.

This regenerative capability helps enterprises:

• reduce electricity costs,
• improve system efficiency,
• lower carbon emissions.

High performance and fast switching

Designed with a fully digital architecture, the BIC-5K offers:

• efficiency up to 93.5%,
• ultra-fast bidirectional switching <1ms,
• low THDi (<3%) and high power factor up to 0.99,
• wide input range 180–305 Vac.

Parallel operation enables system expansion up to 30 kW (5+1 units), making it suitable for scalable industrial systems.

Industrial integration and protection

Key integration features include:

• built-in CANBus or MODBus communication,
• multi-unit configuration for three-phase (3Ø) systems,
• comprehensive protection: anti-islanding, AC abnormality, DC over-voltage, overload, short circuit, and over-temperature.

The unit operates within -30°C to +70°C and features PCB conformal coating for enhanced durability in demanding environments.

Typical applications

• Battery cell formation and grading
• Battery test systems
• Power supply burn-in systems with energy recovery
• Energy storage systems (ESS)
• Vehicle-to-Grid (V2G) applications

Certification and reliability

The BIC-5K is certified to CB, UL, TÜV, RCM, EAC, CE, UKCA, including compliance with 62368-1, 62477-1 and grid-connection standard 50549-1.

Backed by a 5-year warranty.
