The global Integrated Charging Control Unit (ICCU) market was valued at US$ 6434 million in 2024 and is anticipated to reach US$ 13830 million by 2031, witnessing a CAGR of 11.7% during the forecast period 2025-2031.
The integrated charging control unit (ICCU) market is witnessing rapid growth, driven by the global expansion of electric vehicles (EVs) and the need for efficient power electronics. The ICCU is a critical component in EVs that integrates onboard charging (OBC) and DC-DC conversion functions into a single system, offering improved efficiency, reduced weight, and cost savings. As EV adoption accelerates and charging infrastructure expands, the demand for ICCU solutions is expected to rise significantly in the coming years.
What is an Integrated Charging Control Unit (ICCU)?
An integrated charging control unit combines multiple power electronics functions that are typically separate in EVs. It merges the onboard charger and the DC-DC converter into one unit, which simplifies the architecture, reduces components, and enhances performance.
Key benefits include:
- Improved charging efficiency and energy management
- Reduced weight and size, optimizing vehicle design
- Lower manufacturing costs due to fewer components
- Enhanced reliability and integration with battery management systems
- Compatibility with fast-charging technologies
ICCU technology is increasingly adopted by EV manufacturers to optimize powertrain systems and support vehicle electrification.
