FORVIA HELLA has unveiled the Coolant Control Hub max (CCH max), an advanced system centralizing thermal management in electric vehicles. Building on the original Coolant Control Hub, this innovation integrates the drivetrain, battery, and interior thermal management, enhancing performance, reducing complexity, and enabling environmentally friendly refrigerant use.
Key Highlights:
- Innovative Cooling: Individual cooling for vehicle interior and battery using a water-glycol circuit.
- Environmental Benefits: Switch to propane or CO2 to eliminate PFAS chemicals.
- System Efficiency: Halves the number of required cooling and refrigerant valves, eliminates additional electric heaters.
- Weight Reduction: Overall system weight reduced by 20%, decreasing CO2 emissions and increasing vehicle range.
- Market Impact: Significant orders and first launch planned in Mexico.
Jörg Weisgerber, Managing Director Electronics at FORVIA HELLA, stated, “Longer ranges, shorter charging times, and affordability are central for electromobility’s market development. Intelligent thermal management design is key. We have proven the benefits of our subsystem solution with the Coolant Control Hub, and with the CCH max, we are taking the next step.”
Performance Optimization
The Coolant Control Hub max uses a water-glycol cooling circuit to manage the temperature of the drivetrain, battery, and interior, significantly reducing the number of necessary components. This leads to an 80% reduction in refrigerant use, allowing for safe and cost-effective application of natural refrigerants like propane or CO2, eliminating PFAS chemicals entirely.
Intelligent Distribution
The system employs a unique individual cooling method, optimizing target temperatures for both the interior and battery in a shared water-glycol circuit. It incorporates a flexible heat pump system utilizing various heat sources, including ambient air, drivetrain, and the refrigerant system itself. The self-heating mode ensures adequate heat generation when other sources are insufficient.
Efficiency and Sustainability
By eliminating half of the coolant and refrigerant valves and dispensing with electric auxiliary heaters, the Coolant Control Hub max reduces overall system weight by 20%. This weight reduction contributes to lower CO2 emissions and extended vehicle range, aligning with sustainable practices and regulatory standards.
Market Introduction
With orders already placed in the low to mid three-digit million euro range, the Coolant Control Hub max is set for its initial launch in Mexico, marking a significant step in advancing electric vehicle technology and reinforcing FORVIA HELLA‘s leadership in automotive innovation.
