In the context of 48V network vehicles (MILD hybrids, etc.), Valeo offers 48V solutions, an evolution of our 12V technology. These products, using the same PTC stone technology, allow 48V to offer higher voltage and power. In addition, the 48V makes it possible to compensate for the shortage of energy for heating the passenger compartment while the engine heats up.
First fully brazed block on the market (+800 W while maintaining the same number of stones).
High Voltage Coolant heaters (HVCH) were initially developed to heat glycol in the HVAC modules of electric vehicles, ensuring optimal comfort in the cabin. Their role has expanded with battery preheating, an essential functionality in cold climates to preserve the performance and range of electric vehicles.
Valeo wants to democratize the implementation of HVCH by offering a flat design, allowing their integration into compact air conditioning systems and thus meeting all requirements.
High-voltage Air heaters represent the natural evolution of low-voltage 12V PTCs, specifically designed for BEVs. Thanks to PTC stone technology, Valeo high voltage heaters operate at higher powers and voltages, providing superior performance.
With the rise of vehicles equipped with ultra-fast charging technologies operating at 800 V, it is becoming essential to upgrade certain components, particularly those that consume the most energy, to align with this standard. Valeo therefore also offers high voltage air heaters at 800 V.
