The company that makes Bosch’s HV AC system, HVC Systems, is facing a new round of criticism over its use of a carbon-fiber-reinforced plastic (CFRP) material.
As The Verge reported in January, the company uses the material to prevent heat and moisture from escaping from the vents on its HV-1 and HV1 Hybrid vehicles, but it’s not clear how it’s used for other vehicles.
The Verge added that HVC has yet to respond to its article.
In its new defense, Bosch says that its HVC system “uses a low-temperature carbon fiber reinforced plastic (FRP), an extremely light, flexible, and water-resistant material, for its H-VAC systems.
The FRP is highly water resistant, and it has the ability to resist corrosion, moisture, and abrasion,” it wrote.
In a statement, Boschi said that its FRP “is used for both vehicle heating and cooling and is manufactured in small batches, with a limited production life, and at temperatures above -100 degrees Fahrenheit.”
The company also said that it “does not currently produce FRP for its other HV systems, including the HV8 Hybrid, HVT Hybrid, and HVT-X Hybrid.”
Bosch did not immediately respond to a request for comment.
Bosch said it is “looking into” the controversy.
